Terms of Use

Last updated

These Terms of Use govern your use of the Arca app and the https://arca.pacifiq.io website, operated by Pacifiq. By downloading or using Arca, you agree to these terms.

The most important thing to understand

Arca is zero-knowledge. Your photos are encrypted with a key derived from your PIN, which is never stored or transmitted. This means:

  • We cannot recover your PIN or decrypt your vault if you forget it.
  • We cannot retrieve, reset, or restore your data for you.
  • You are responsible for remembering your PIN and keeping your own encrypted backups.

This is the deliberate cost of genuine privacy. Please take it seriously.

License

We grant you a personal, non-exclusive, non-transferable, revocable license to use Arca on Apple devices you own or control, in accordance with the App Store Terms of Service and these terms.

Acceptable use

You agree to use Arca lawfully and only to store content you have the right to store. You may not use Arca to store or distribute unlawful material, or attempt to circumvent its security or licensing.

Purchases and subscriptions

Arca is free to download. Premium is available as an annual subscription ($29.99/year) or a one-time lifetime purchase ($79.99). Subscriptions auto-renew unless cancelled at least 24 hours before the period ends; manage or cancel in your Apple ID settings. A lapsed subscription does not delete or lock photos you have already imported.

No warranty

Arca is provided “as is.” While we design Arca for strong security, no software is perfectly secure, and we make no guarantee that the app will be uninterrupted or error-free. To the maximum extent permitted by law, we disclaim all implied warranties.

Limitation of liability

To the maximum extent permitted by law, Pacifiq is not liable for any indirect, incidental, or consequential damages, or for loss of data arising from a forgotten PIN, a missing backup, or device loss or failure.

Changes

We may update these terms as the app evolves. Continued use after changes constitutes acceptance of the updated terms.
