Data collection
The developer does not collect, transmit, sell, or share your passwords, account details, document numbers, notes, or document images. The App contains no advertising, analytics, or cross-app tracking SDK.
Local storage
Information you enter and images you select are stored in the App’s private container on your device using Apple system storage technologies. The App has no developer-operated account system, cloud service, or remote backup service.
Photos and camera
Photo-library or camera access is requested only when you choose to add or save a document image. Selected images remain on your device and are not uploaded to the developer.
Payments
If you obtained the App through Apple’s App Store, Apple processes the purchase, taxes, and refunds under its own policies. The developer does not receive your complete payment-card information.
Deletion and retention
You can delete individual entries in the App. Deleting the App removes its local data from that device, subject to device backups you control. Because the developer does not receive your vault, the developer cannot view or recover it.
Children
The App is not directed at children and does not knowingly collect personal information from children.
Changes
This policy may be updated when the App’s functionality or legal requirements change. The revision date above identifies the current version.
