The Punch — Terms of Use and End User Licence Agreement

Product: The Punch, a punch-list add-in for Autodesk Revit, and for Autodesk Navisworks Manage and Simulate on the same subscription

Brand: Caltior

Offered by: Duckbird LLC, under the Caltior brand

Document date: 15 September 2026 — Document revision: SCHEDULE-P-2026-09-15 — revision 27

Revision history: rev 1, 27 July 2026 (first publication). rev 2, 27 July 2026 (clauses 15.1 and 20.5: support and notices address corrected to Caltior@caltior.io, replacing an address that did not accept mail). rev 3, 28 July 2026 (clauses 6.1 and 6.2: Revit 2026 corrected to supported. The previous wording stated Revit 2026 had no shipping configuration, manifest or installer path - true when first written, and no longer true. The storefront and the installer both cover Revit 2024, 2025 and 2026, and this correction brings these terms into agreement with them. No entitlement is reduced by this change). rev 4, 2 August 2026 (clauses 6.1 and 6.2: Revit 2023 added to commercial support. Owner confirms the shipping installer includes a functional 2023 path; storefront and these terms now state Revit 2023, 2024, 2025 and 2026. No entitlement is reduced by this change). rev 5, 2 August 2026 (clause 7.1.1: July 2026 launch promotion recorded as closed/ended; storefront no longer offers it. Standard monthly and annual prices in 7.1.2 and 7.1.3 are the current offer. No entitlement is reduced for customers whose first period was already billed under the closed promotion). rev 6, 3 August 2026 (clauses 6.1 and 6.2: Revit 2022 added to commercial support. Installer ships a dedicated 2022 payload with Newtonsoft.Json 13.0.1 for hosts that lack it. No entitlement is reduced by this change). rev 7, 4 August 2026 (administrative record only: a prior draft claimed a further support/notices mailbox change; the public contact was already Caltior@caltior.io from rev 2 — no substantive mailbox change). rev 8, 12 August 2026 (metadata hygiene only: header revision number aligned to history; revision history placed in chronological order; product Version set to the shipping installer series 0.2.13; document date and Document revision id aligned. No entitlement is reduced by this change). rev 9, 12 August 2026 (product Version set to shipping installer series 0.2.14 — zoom last-known + plain-language dialogs; no entitlement reduced by this change). rev 10, 12 August 2026 (product Version set to shipping installer series 0.2.15 — licence block command-links; no entitlement reduced). rev 11, 15 August 2026 (Owner directive D-EXEC-NO-PUBLIC-MECHANISM: read-this-first item 1 and clause 11 restated so the storage method is not described; backup and liability duties unchanged; no entitlement reduced). rev 12, 22 August 2026 (Owner GO: Navisworks Manage/Simulate 2024-2027 is the same Punch subscription as Revit, not a second product. Clauses 1/read-this-first, 4.3, 5.5, 6.5-6.7, 11.1-11.2, 14.4. No entitlement reduced). rev 13, 22 August 2026 (Owner GO: Central America and the rest of South America added to sold territory. Clauses read-this-first 3, 7.10, 7.10.7, 19.3. Mexico and the Caribbean remain closed. No entitlement reduced). rev 14, 23 August 2026 (Owner: complete GST side. Canada, India, New Zealand, Singapore added to sold territory; Stripe Tax GST/HST/GST registrations active. Clauses 7.10, 7.10.8. Mexico/Caribbean/CH remain closed. No entitlement reduced). rev 15, 23 August 2026 (GST pack remains sold; Stripe Tax collection for IN/CA/NZ/SG expired. Collect-and-hold rejected. File when volume warrants. No entitlement reduced). rev 16, 23 August 2026 (Owner: global road. Collect where Stripe Tax registers; payable not revenue; file at volume. Letter/assessment/Stripe are the pressure, not a raid in the USA. No entitlement reduced). rev 17, 23 August 2026 (Owner: open Mexico, Switzerland, and Caribbean billing. China (CN) remains not sold. No entitlement reduced). rev 18, 23 August 2026 (Owner: new subscriptions USD $15.00/month or $150.00/year. Prior published-price subscriptions renew at that subscription's Stripe price until cancelled. No entitlement reduced). rev 19, 24 August 2026 (Owner: live download Navisworks host is Manage/Simulate 2027. Storefront and clause 6.5 state 2027, not 2024-2027). rev 20, 24 August 2026 (product Version set to shipping installer series 0.2.77. No entitlement reduced). rev 21, 24 August 2026 (Owner: live download Navisworks host is Manage/Simulate 2024-2027. Storefront and clause 6.5 restored from 2027-only. No entitlement reduced). rev 25, 5 September 2026 (Owner: clean client face. The Punch stops when the licence expires. Former 8.3 post-expiry CSV export is withdrawn and is not a separate entitlement. Data is not deleted. CSV is not described as a special right.). rev 26, 6 September 2026 (Owner legal recovery: new-sale price is the USD amount displayed and accepted at checkout for the selected application set and billing period. $15/$150 is no longer described as the universal current offer. Mutable installer Version 0.2.77 removed from the header; supported host years remain in clauses 6.1 and 6.5. Prior published-price subscriptions including launch $12 continue at that Stripe price. No entitlement reduced for existing subscribers.)

Revision history (continued): rev 22, 31 August 2026 (Owner GO C-LEGAL-SP-001: clauses 8.4, 11.7, and 13.1 scrubbed of public implementation mechanics under D-EXEC-NO-PUBLIC-MECHANISM; data-not-deleted, post-expiry CSV export, no model access, offline use, backup, as-is/liability, and clause 11.1 confidential-methods preserved. No entitlement reduced). rev 23, 4 September 2026 (Owner: you agree not to reverse engineer, copy, or use any part of information pathways or code via AGI, human, or other — covenant, not only a you-may-not restriction. Clause 5 restated as you agree that you will not; 5.3 expanded; 14.1 names information pathways as Caltior property; 14.5 All rights reserved for legal recourse if breached. No entitlement reduced). rev 24, 5 September 2026 (Owner Change: if the licence expires, Export CSV stops. Restores the 0.2.77 product rule. Clauses 3.3, 8.2, 8.3, 8.4, 18.5. This reduces the post-expiry CSV entitlement previously stated in 8.3. 18.5 no longer preserves 8.3 as a post-termination export right. Punch items already in your models are not deleted; CSV files you already exported remain yours.)

Revision history (continued): rev 27, 15 September 2026 (Owner GO: open selling to China (CN) at the published USD list. Clauses 3, 7.10, 7.10.1, 7.10.7, 7.10.9, 19.3. Cuba remains not sold. Hong Kong, Macau, and Taiwan are not this pack. No entitlement reduced.)


Read this first — three things to know before you buy

1. The Punch runs in your Revit or Navisworks session. Caltior does not host your punch list. Your items stay on your side. Keep backups of project work you care about. Clause 11 covers this, and clauses 12 and 13 limit what Caltior is responsible for if something goes wrong. Please read all three before you buy.

2. The installer is not code-signed. Caltior has not yet purchased a code-signing certificate. When you run the MSI, Windows SmartScreen will warn you that the publisher is unknown. This is expected and is not a sign that the download is compromised — but you should verify you downloaded it from caltior.io and nowhere else. Clause 10 covers this.

3. The Punch is currently sold in the United States, Australia, Brazil, Europe (EU member states, the United Kingdom, and the EEA), Central America, South America, Canada, India, New Zealand, Singapore, Mexico, Switzerland, the Caribbean, and China only. Caltior has not yet completed the regulatory, licensing and tax obligations that selling into other territories requires, and would rather decline a sale than make one it is not properly set up to make. If your billing country is outside the packs listed in clause 7.10, The Punch is not available to you yet. Clause 7.10 covers this.

None of these three facts is buried in this document, because none of them should be a surprise after you have paid.


1. These terms

1.1 These terms are the agreement between you and Caltior for your use of The Punch. By installing or using The Punch, you accept them.

1.2 If you are accepting these terms for a company or other organisation, you confirm you are authorised to do so, and "you" means that organisation.

1.3 If you do not accept these terms, do not install The Punch. If you have already paid, contact Caltior — see clause 7.4 on refunds.

2. Who you are contracting with

2.1 The Punch is offered under the Caltior brand by Duckbird LLC, the contracting seller and payment recipient. You are contracting with Duckbird LLC, a Delaware limited liability company, for your use of The Punch.

2.2 Duckbird LLC's business address for these terms is 8 The Grn Ste A, Dover, DE 19901, United States.

2.3 "Caltior" is the brand The Punch is sold under. "We", "us" and "our" in these terms mean Duckbird LLC, except where a clause expressly names a different party. Where these terms say "Caltior" does or may do something, that obligation or right is Duckbird LLC's.

2.4 Payment is processed by Stripe on behalf of Duckbird LLC. Your receipt and bank statement may show the payment processor or merchant descriptor used for the charge.

2.5 Caltior may in future be operated by a separate company. If the contracting party changes, clause 20.4 governs the transfer: your rights are not reduced, you are given any notice required, and access you have already paid for continues.

3. What you are buying

3.1 You are buying a licence to use The Punch for as long as your subscription is paid and current. You are not buying the software itself.

3.2 The software is licensed, not sold. Caltior keeps ownership of it. Clause 14 sets this out.

3.3 Your licence is enforced by a signed licence file with an expiry date matching the period you have paid for. When that date passes without renewal, the licence expires and The Punch stops until you renew. See clauses 7 and 8.

4. What your licence allows

4.1 Subject to these terms and to your subscription being current, Caltior grants you a non-exclusive, non-transferable, revocable licence to install and use The Punch.

4.2 Scope: one named individual per subscription. One subscription covers use by one named person. At checkout you may name the Autodesk email of that person, including when someone else pays. The licence file is bound to that Autodesk sign-in. That person may install The Punch on more than one computer they personally use — for example a desktop and a laptop — but the licence may not be shared with, passed to, or used concurrently by anyone else. If you need to cover more people, buy a subscription for each.

4.3 You may use The Punch on any Revit or Navisworks project you are lawfully entitled to work on, including client projects and commercial work. Punch item data and files you save are yours; Caltior claims no rights over them.

4.4 If you change employer or the named user changes, tell Caltior and the licence can be reassigned. A subscription may not be rotated between people to avoid buying additional seats.

5. What your licence does not allow

You agree that you will not:

5.1 Copy, distribute, resell, sublicense, rent, lend, or host The Punch for anyone else's use.

5.2 Share your licence file, or attempt to alter, forge, bypass, or defeat the licence check or its expiry date.

5.3 Reverse engineer, decompile, disassemble, copy, extract, reconstruct, or otherwise use any part of The Punch's information pathways or code — whether by a human, by AGI or any other artificial intelligence system, automated agent, or by any other actor, tool, or process — except to the exact extent that applicable law gives you a right to do so that cannot be excluded by contract. Ordinary licensed use of The Punch under clause 4 is not a breach of this clause 5.3. You agree not to permit any such actor to do those things on your behalf. This includes using any part of those information pathways or code to train, specify, reconstruct, or build any system or product.

5.4 Remove or obscure any copyright, trademark, or ownership notice.

5.5 Use The Punch to build a competing product, or use it in a way that breaks the law or Autodesk's own terms for Revit or Navisworks.

6. Host versions and your own Autodesk licences

6.1 The Punch is commercially supported on Autodesk Revit 2022, 2023, 2024, 2025 and 2026.

6.2 Revit 2022 and 2023 are supported as of the current shipping installer. Earlier published terms stated otherwise while commercial evidence was still limited; that restriction is withdrawn. You still need your own valid Autodesk Revit licence for whichever year you run (clause 6.3).

6.3 The Punch is an add-in. It requires your own valid, separately licensed installation of Autodesk Revit. Caltior does not supply Revit and is not affiliated with or endorsed by Autodesk.

6.4 If a future release of The Punch drops support for a Revit version you use, you may cancel under clause 7.3 and stop paying.

6.5 The same subscription also covers The Punch in Autodesk Navisworks Manage and Autodesk Navisworks Simulate 2024-2027. This is not a second product and not a second fee.

6.6 Navisworks use requires your own valid, separately licensed installation of Navisworks Manage or Simulate. Caltior does not supply Navisworks.

6.7 If a future release of The Punch drops support for a Navisworks year you use, you may cancel under clause 7.3 and stop paying.

7. Subscription, payment, and renewal

7.1 The available subscription prices are:

7.1.1 July 2026 launch promotion — closed. For subscriptions that began between 1 July and 31 July 2026, the first monthly billing period was USD $8.00, then renews at USD $12.00 per month. That one-period launch promotion has ended and is not offered for new subscriptions. Customers already billed under it keep the period they paid for; later renewals stay on that subscription's monthly Stripe price (USD $12.00 for those launch subscriptions), not the current offer.

7.1.2 New-sale price. For a new subscription, the price is the USD amount displayed and accepted at checkout for the selected application set and billing period. Applicable tax may be added at checkout.

7.1.3 Billing period. Monthly subscriptions renew monthly. Annual subscriptions are paid upfront and renew annually. The amount for that period is the amount displayed and accepted at checkout.

7.1.4 Prior published prices. A subscription that began at a prior published monthly or annual price continues to renew at that subscription's Stripe price until it is cancelled. That prior price is not offered for new subscriptions.

7.2 Payment is processed by Stripe. Card details are handled by Stripe and are not held by Caltior. Stripe's own terms apply to the payment itself.

7.3 The subscription renews automatically on the cadence you choose — monthly or annually — until you cancel. You may cancel at any time, effective at the end of the period you have already paid for. Cancelling stops the next renewal; it does not shorten a paid period and does not, by itself, entitle you to money back — see 7.4.

7.4 Refunds: none, beyond what the law requires.

7.4.1 Payments are not refundable. Cancelling stops future payments; it does not refund a payment already taken.

7.4.2 There is no pro-rata refund for the unused part of a paid period. If you cancel mid-period, your licence runs to the end of the monthly or annual period you have paid for and then expires.

7.4.3 This does not, and cannot, take away rights the law gives you that an agreement is not allowed to remove. Consumer-protection law in some countries grants refund or cancellation rights that cannot be signed away. Where you have such a right, you keep it in full, and clause 7.4.1 does not apply to it. If you believe you have one, contact Caltior and say so — it will be honoured rather than argued about.

7.4.4 Nothing above limits what Caltior may choose to do voluntarily in a particular case. It sets out what you are entitled to, not the most that will ever be offered.

7.5 If a payment fails and is not resolved, the subscription lapses and clause 8 applies.

7.6 Caltior may change the price. Any change applies from your next renewal, not mid-period, and you will be told before it takes effect. If you do not want to pay the new price, cancel before that renewal.

7.7 Prices are in US dollars and exclude any sales tax, VAT, or similar charge that may apply where you are.

7.8 Supply starts immediately, and you are asked to agree to that. When you subscribe, Caltior issues your licence file straight away rather than waiting — that is the point of the product. By subscribing you request immediate supply and acknowledge that, in countries where a consumer would otherwise have a short cancellation window for digital content, beginning supply immediately at your request may end that window. This is stated here because it is the reason clause 7.4 can say what it says; it is not buried, and it is not a trick.

7.9 Auto-renewal, in plain terms: this is a recurring monthly or annual charge, depending on the plan you choose, and it continues until you cancel. For a new sale, renewal is at the USD amount displayed and accepted at checkout for that plan. A subscription that began at a prior published price renews at that subscription's Stripe price. You can cancel at any time through the Stripe billing portal linked from your receipt — or by emailing Caltior. Cancellation stops the next renewal and takes effect at the end of the period already paid for.

7.10 Where The Punch is sold: the United States, Australia, Brazil, Europe, Central America, South America, Canada, India, New Zealand, Singapore, Mexico, Switzerland, the Caribbean, and China, for now.

7.10.1 The Punch is offered for purchase to customers whose billing country is the United States (US), Australia (AU), Brazil (BR), a country in the Europe pack (EU member states, the United Kingdom (GB), and the EEA states Iceland, Liechtenstein, and Norway), a country in the Central America pack (Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panama), or a country in the South America pack (in addition to Brazil: Argentina, Bolivia, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, Venezuela), Canada (CA), India (IN), New Zealand (NZ), or Singapore (SG), Mexico (MX), Switzerland (CH), or a country in the Caribbean pack (independent Caribbean states and common Caribbean billing territories; Puerto Rico and the US Virgin Islands are United States; Cuba is not sold), or China (CN). It is not currently offered for purchase from other territories.

7.10.2 This is not a judgement about those markets. Selling software into other territories brings regulatory, licensing and tax obligations that Caltior has not yet completed, and it would rather decline a sale than make one it is not properly set up to make. Other territories will be considered once those obligations can be met.

7.10.3 If a subscription is taken out from outside the allowed territories listed above, Caltior may cancel it and refund what was paid. That is the one situation in which a refund is given as a matter of course, and clause 7.4 does not stand in its way: Caltior should not keep money for a sale it was not in a position to make.

7.10.4 Nothing in this clause restricts *where you may use* The Punch. It concerns where it is sold. If you subscribe in the US and then work on a project abroad, that is fine — clause 4.3 already allows it.

7.10.5 Australia. Non-excludable rights under the Australian Consumer Law are preserved by these terms (including clause 7.4.3). Applicable tax is calculated at checkout via Stripe Tax when registrations are active; tax registrations remain Owner residual. Storefront prices remain in USD unless a Schedule states otherwise.

7.10.6 Europe (EU, UK, EEA). Non-excludable consumer rights under applicable EU member state law, UK law, or EEA law are preserved by these terms (including clause 7.4.3). Digital content / distance-selling withdrawal rules apply only as required by law; where you consent to immediate digital supply and acknowledge loss of withdrawal, supply may begin at once (see also clause 7.8). Applicable VAT is calculated at checkout via Stripe Tax when registrations are active; VAT/OSS and UK VAT registrations remain Owner residual. List prices remain USD exclusive unless a Schedule states otherwise. Caltior does not provide tax advice.

7.10.7 Central America and South America. Non-excludable consumer rights under applicable local law are preserved by these terms (including clause 7.4.3). Applicable tax is calculated at checkout via Stripe Tax when registrations are active; tax registrations remain Owner residual. List prices remain USD exclusive unless a Schedule states otherwise. Caltior does not provide tax advice. French Guiana is sold via the Europe pack (France), not this pack. Mexico and the Caribbean pack are sold under clause 7.10.1.

7.10.8 Tax at checkout (global). Where Stripe Tax has an active registration for the billing country, applicable GST/HST/VAT/IGST is added on top of the USD list price. That amount is a payable until volume warrants filing and remittance. Where Stripe Tax has no registration, the charge is the USD list price. Non-excludable local rights are preserved (clause 7.4.3). This clause does not invent a tax ID. Caltior does not provide tax advice.

7.10.9 China (CN). Non-excludable consumer rights under applicable PRC law are preserved by these terms (including clause 7.4.3). Applicable tax is calculated at checkout via Stripe Tax when registrations are active; tax registrations remain Owner residual. List prices remain USD exclusive unless a Schedule states otherwise. Caltior does not provide tax advice. Hong Kong (HK), Macau (MO), and Taiwan (TW) are not this pack.

8. What happens when your licence expires

8.1 When a subscription is cancelled, lapses, or is not paid, your licence file expires on the last day of the period you paid for.

8.2 When the licence expires, The Punch stops until you renew. Those ribbon commands will refuse to run and will tell you the licence has expired. This is by design and is not a fault.

8.3 Your punch items stay in your models. Caltior does not hold a copy of them.

8.4 Your data is not deleted. Punch items and files you already saved remain yours and remain readable after the licence ends. Without a valid licence you cannot use The Punch until you renew.

8.5 Resubscribing issues a new licence file and restores full access to data still held in your models. You do not need to restart Revit — the licence is re-read the next time you use a command.

9. Installation and updates

9.1 The Punch is distributed as a Windows MSI installer, downloaded from caltior.io. Do not install a copy obtained from anywhere else.

9.2 Caltior may release updates. Updates are provided under these same terms. Caltior does not promise any particular release schedule, feature, or fix.

10. The installer is not code-signed

10.1 As at the date of this document, the MSI is not code-signed. Caltior has not purchased a code-signing certificate.

10.2 The practical effect: when you run the installer, Windows SmartScreen will show an "unknown publisher" warning, and you will have to click through it to continue. Your organisation's IT policy or antivirus may also block it.

10.3 This is disclosed here so that it is not a surprise after payment. It reflects the current state of Caltior's tooling, not a problem with the download itself — provided you downloaded it from caltior.io.

10.4 If your organisation cannot install unsigned software, The Punch will not work for you today. Please do not buy it on the expectation that this changes.

11. Your project data, and backups — please read

11.1 The Punch runs inside Revit or Navisworks on your computer. Caltior does not host, receive, or store your punch items. How the product keeps that list is Caltior confidential information and is not described in these terms. You can export your list to CSV.

11.2 You remain responsible for your project files and for any effect The Punch has while it runs in Revit or Navisworks. Caltior does not operate a punch-list server for your job.

11.3 You are responsible for backing up your models. Keep backups appropriate to how important the work is, before installing The Punch and on an ongoing basis afterwards. If you use a central model, follow your normal backup and sync practice.

11.4 Software can have defects. The Punch is an early commercial release. A defect that corrupts, loses, or wrongly overwrites your project data is a real possibility, not a theoretical one, and a current backup is the only reliable protection against it.

11.5 Caltior strongly recommends trialling The Punch on a copy of a model before using it on live project work.

11.6 CSV files you export are written to a location you choose and are then entirely under your control. Caltior does not receive them.

11.7 Caltior does not receive, collect, or have access to the contents of your project models. Licence checks run on your machine from your licence file. The Punch is designed to work offline, including on air-gapped or restricted site networks. Caltior does not operate a licence server that receives your model contents.

12. No warranty

12.1 The Punch is provided "as is" and "as available", without warranty of any kind, express or implied.

12.2 In particular, Caltior does not warrant that The Punch will be free of defects, will run without interruption, will be compatible with your particular Revit configuration, add-ins, hardware, or workflow, or that it will preserve the integrity of your project data.

12.3 To the fullest extent the law allows, all implied warranties and conditions — including any as to merchantability, satisfactory quality, or fitness for a particular purpose — are excluded.

12.4 Nothing in this clause affects any legal rights you have as a consumer that cannot be excluded by agreement. Where such rights apply, they stand.

13. Limitation of liability

13.1 This clause matters. Please read it alongside clause 11. The Punch is a low-cost subscription — the USD amount displayed and accepted at checkout — and your project files may be worth a great deal more. The allocation of risk below is what makes it possible to offer the product at those prices.

13.2 Caltior is not liable for: loss of or damage to data; corruption of Revit models; loss of profit, revenue, business, contracts, or anticipated savings; loss of goodwill; project delay; the cost of reconstructing lost work; or any indirect or consequential loss — however caused, and whether or not Caltior was told such loss was possible.

13.3 Where Caltior is liable, its total aggregate liability to you, for all claims arising out of or in connection with The Punch and these terms, is limited to the total amount you actually paid Caltior in the twelve (12) months immediately before the event giving rise to the claim.

13.4 Nothing in these terms excludes or limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot lawfully be excluded or limited.

13.5 You accept that keeping backups (clause 11.3) is your responsibility, and that the limits in this clause are reasonable given the price of the product and the fact that you control your own backup practice.

14. Intellectual property

14.1 The Punch, including its source code, compiled binaries, information pathways, interface, documentation, name, and branding, is and remains the property of Caltior. All rights reserved. All rights not expressly granted in clause 4 are reserved.

14.2 Nothing in these terms transfers any ownership of the software to you.

14.3 Your project data is yours. Punch items, model content, and files you save using The Punch belong to you, and Caltior claims no licence or interest in them.

14.4 "Autodesk", "Revit", and "Navisworks" are trademarks of Autodesk, Inc. Caltior is not affiliated with, authorised by, or endorsed by Autodesk.

14.5 All rights reserved — legal recourse. If you breach these terms, including clause 5, Caltior reserves all rights and all legal recourse, including damages, injunctive or other equitable relief, termination, and any other remedy available at law or in equity, to the maximum extent permitted by law. Those remedies are cumulative and not exclusive, and they survive termination.

15. Support

15.1 Support requests may be sent to Caltior@caltior.io.

15.2 No response time or service level is promised in this document, and none should be inferred. Support, where offered, is provided on a reasonable-efforts / best-effort basis only.

15.3 Support does not extend to your Revit installation, your hardware, your network, other add-ins, or the content of your models.

16. Privacy and personal data

16.1 Caltior processes a small amount of personal data: the name and email address used to buy the subscription (handled by Stripe as payment processor), and the email address embedded in your licence file so it can be identified as yours. Punch items you create - including any assignee names you type - stay on your side and are never transmitted to Caltior. The add-in may contact caltior.io to check for an installer update, to confirm a subscription is current at renewal, and about every five days while The Punch is in use so Caltior can tell a licensed copy is running. Those calls send the email on your licence, the add-in version, and a random install id. They do not send your models or punch items. If the machine is offline, The Punch keeps working until the signed licence expiry. Access stops after the subscription is not paid (and any remaining days on the signed file). See the Privacy Notice for detail and for how to make a request about your data.

16.2 Payment details are handled by Stripe under Stripe's own privacy terms. Caltior does not store your card details.

16.3 Caltior does not receive the contents of your Revit models. See clause 11.7.

17. Changes to these terms

17.1 Caltior may change these terms — for example to reflect changes to the product, the law, or the way it operates.

17.2 If a change is material and unfavourable to you, Caltior will give you at least 30 days notice before it takes effect, sent to the email address on your subscription.

17.3 If you do not accept a change, cancel before it takes effect. Continuing to use The Punch after that date means you accept the changed terms.

17.4 Changes will not be applied retrospectively to a period you have already paid for.

18. Termination

18.1 You may terminate at any time by cancelling your subscription. Clause 8 applies.

18.2 Caltior may terminate or suspend your licence if you materially breach these terms — in particular clause 5. Where the breach can be put right, Caltior will give you notice and a reasonable chance to fix it first, unless the breach is deliberate.

18.3 If Caltior terminates for breach, no refund is due for the remainder of the current period.

18.4 If Caltior discontinues The Punch, it will give reasonable notice, stop taking further payments, and let every licence already paid for run to its expiry date. Your last paid month is served in full; discontinuation does not cut it short. On that basis no refund arises, because nothing you paid for goes undelivered.

18.4.1 Caltior will not stop supply part-way through a period you have paid for. Refusing a refund *and* withdrawing access mid-period would be keeping money for something not provided, which is a different matter from clause 7.4 — there, you chose to leave; here, Caltior did.

18.5 On termination, you must stop using The Punch and uninstall it. Clauses 8.4, 12, 13, 14, and 19 survive termination.

19. Governing law and disputes

19.1 These terms, and any dispute arising out of them, are governed by the laws of the State of Delaware and the federal laws of the United States, without regard to conflict-of-laws rules.

19.2 The state and federal courts located in New Castle County, Delaware have exclusive jurisdiction, except that nothing prevents a consumer from bringing proceedings where local consumer law entitles them to do so.

19.3 Because The Punch is sold only in the territories listed in clause 7.10, Delaware and US federal law remain the chosen governing law. Local mandatory consumer rights in an allowed territory (including Australia, Europe pack, Central America, South America, Canada, India, New Zealand, Singapore, Mexico, Switzerland, Caribbean, and China jurisdictions) are preserved where they cannot be excluded. Clause 7.4.3 nonetheless preserves any non-excludable local rights, for the case of a subscription taken from outside the US before Caltior can decline it.

20. General

20.1 Entire agreement. These terms are the whole agreement between you and Caltior about The Punch, and replace any earlier discussion or representation.

20.2 Severability. If any clause is found unenforceable, the rest continues to apply.

20.3 No waiver. If Caltior does not enforce a right immediately, it does not lose it.

20.4 Assignment and affiliate transfer. You may not transfer your licence or these terms to anyone else without Caltior's written agreement. Caltior may transfer these terms, your subscription relationship, and related customer records to an affiliate under common ownership as part of consolidating the commercial relationship, provided: (a) your rights under these terms are not reduced; (b) any notice required by these terms or applicable law is given; and (c) subscription continuity and paid access for the period already paid are preserved. A transfer under this clause is not a new sale and does not restart a refund or cooling-off period. Other assignment by Caltior as part of a sale or reorganisation of its business is also permitted on the same "rights not reduced" condition.

20.5 Notices. Caltior will contact you at the email address on your subscription. You can contact Caltior at Caltior@caltior.io or by post to Duckbird LLC, 8 The Grn Ste A, Dover, DE 19901, United States.
