Terms of Use

Last updated: September 18, 2026

These terms describe Vailuna, provided by Yayun Liu, including subscriptions and responsibility for your data. Please also read our Privacy Policy and the notices for your version, platform and purchase channel.

1. License and your content

Your photos, videos, files and passwords remain yours. Only store, import or share content you are entitled to use. Do not infringe others’ rights or use the app unlawfully. Apps obtained through the App Store are subject to Apple’s Standard End User License Agreement (EULA). This page supplements product and service information and does not replace that license. Third-party components retain the licenses listed in the app’s Open Source Licenses screen.

2. Passwords and recovery

Your vault is encrypted on-device. Keep your master password and any recovery information you set up safe. Biometrics authorize local access; they do not give the developer your password or keys. We cannot decrypt your vault for you. Losing all valid unlock and recovery methods may make your data unrecoverable.

3. Pro subscriptions and cancellation

Pro offers the additional features listed on the purchase screen. Benefits, supported platforms, monthly or annual billing, local-currency prices and available offers are shown in the app and Apple’s purchase confirmation. Pro does not include cloud storage capacity or pay third-party cloud fees.

Apple bills App Store purchases to your Apple Account. Subscriptions generally renew automatically unless cancelled. Use Manage Subscription in the app or Apple’s subscription settings to check renewal dates and cancel. Access normally continues until the paid period ends. Uninstalling the app, disconnecting sync or deactivating a desktop does not cancel a subscription. Refund requests go to Apple; eligibility is determined by Apple and applicable rules.

Restore purchases with the Apple Account used to buy them. Expiry may restrict Pro features but does not itself delete your vault files. TestFlight and sandbox purchases are for testing and are not production paid entitlements.

4. Your cloud and desktop activation

Sync uses your own cloud account or selected folder. Cloud capacity, connectivity, account authorization and provider rules affect availability. Activating a desktop grants access to features; it does not mean your data has synced. Devices must use compatible sync settings and open the same vault. Full storage, network outages or expired authorization can leave uploads or downloads incomplete.

Sync is not an independent backup: deletions and replacements may propagate to other devices. Before moving a vault or cleaning an old backup, verify the destination and keep any independent backup you need. Disconnecting sync does not automatically erase every previous location or version retained by your provider.

5. Photo optimization and original replacement

Compressing and replacing originals can be irreversible. Lossy compression changes pixels; HDR-to-SDR conversion changes dynamic range. Allowing camera extras to be omitted can remove proprietary camera fields. The app attempts to preserve important metadata and validate output according to your settings, but this is not a promise of byte-for-byte identity or compatibility with every editor or camera feature.

Read the quality, HDR, metadata and backup notices before proceeding. Once a replacement is complete and recoverable backups are removed, discarded pixels and information cannot be restored by the app. Keep independent originals of important material. Unsupported or unvalidated items are retained or skipped as indicated by the operation result.

6. Sharing, external services and availability

Export, sharing and AutoFill pass relevant content to the system feature, app or recipient you choose. Those copies are no longer protected solely by the vault. Enabling full web rendering can allow scripts and remote resources in a file to access the network. Use these features only with content you trust.

Features depend on operating system, hardware, version and third-party services. We cannot guarantee uninterrupted or error-free operation on every device or cloud service. Check the reported outcome of operations. Nothing here excludes consumer rights or liability that cannot lawfully be excluded.

7. Updates and contact

Changes are dated on this page. Material changes requiring notice or consent will be handled as applicable; updating a webpage does not replace required consent. Visit Help & Support or email [email protected] with questions.
