Calt Vault free public beta — download agreement

By checking the box and downloading, you confirm that you understand and agree:

  • This is BETA testing software, not production 1.0. Features may change, break, or lose data.
  • You take all responsibility for downloading, installing, operating, passphrases, backups, data integrity, suitability, and all outcomes. You use Calt Vault entirely at your own risk.
  • The software is provided as-is and as available, with no warranty of any kind to the maximum extent permitted by law.
  • To the maximum extent permitted by law, Caltior is not liable for loss of data, lost passphrases, corruption, lost profit, business interruption, indirect or consequential loss, or any claim arising from beta use. Where liability cannot be excluded, aggregate liability for free beta is limited to the greater of USD 0 and amounts you actually paid Caltior for Vault in the twelve months before the claim (expected: USD 0 during free beta).
  • Nothing here excludes rights that applicable law does not allow to be excluded (including, where applicable, liability for fraud or for death/personal injury caused by negligence).
  • The build may be unsigned; Windows SmartScreen / unknown publisher warnings may appear. Download only from caltior.io.
  • You will keep originals/backups of anything important. Caltior cannot recover lost passphrases.
  • Calt Vault is not AGI-proof and is not a managed service — you operate the tool.

This click-to-agree gate is a website beta download agreement, not a full paid-product EULA. Production 1.0 terms, if any, will be stated when a paid product ships.
