Postcard Archive is an offline, private archival app for postcard collectors. This policy explains, plainly, what we do and do not collect.

What we collect

Nothing. Postcard Archive has no user accounts, no cloud sync, no analytics, no advertising, no crash reporters that transmit data, and no tracking of any kind.

The app does not contact any server we control. It does not contact any third-party server. It does not need an internet connection to function.

What stays on your device

Every postcard you add to Postcard Archive — including the front and back images, captions, dates, locations, stamp and postmark notes, condition, themes, transcriptions, and any other field you fill in — is stored only in this app’s local storage on your device.

The app does not transmit this data anywhere.

Photos and camera permission

If you grant the app access to your photo library, the app reads images you select. The selected image is copied into your local archive. The app does not upload your photos.

If you grant camera access (where applicable), the app captures images directly into your local archive. Camera frames are not transmitted.

You can deny or revoke these permissions at any time in your operating system’s Settings; the app will still run but image-capture features will be unavailable.

Exports

You can export your archive as a CSV or JSON file from the app’s Settings screen. The exported file is written to a local temporary location on your device and offered to you through the system share sheet, where you choose the destination (Files, AirDrop, Mail, another app, etc.).

Postcard Archive Pro can also create a full archive backup file for your own safekeeping. On Android, this backup is a passphrase-protected encrypted .pcabak file. The passphrase is chosen by you and is not sent to us. If you share or store that backup elsewhere, that destination’s privacy and security practices apply.

The contents and destination of an exported file are entirely under your control. We do not see what you export or where you send it.

Backups

On iOS and iPadOS, the app’s data is included in iCloud Backup or Mac/iTunes encrypted backups according to Apple’s standard rules for app sandbox data. On macOS (Mac Catalyst), the app’s data lives inside its Mac App Sandbox container and is included in your Mac’s Time Machine backups if you have Time Machine enabled. The data is not synchronised separately by us.

On Android, the app opts out of Google Auto Backup for Apps. The postcard database is not copied to Google’s servers by the app, and Android cloud backup is disabled for Postcard Archive. To move or preserve your archive, use the in-app export and passphrase-protected encrypted backup tools that you control.

Children’s privacy

The app does not knowingly collect any personal information from anyone, including children under 13. The app contains no advertising and no behaviour tracking.

Data sharing

We do not sell, share, rent, or otherwise disclose your data because we never have it. The app stays local.

Changes to this policy

If we change this policy, the new version will appear in a future release of the app and at this URL. The version of this document that ships with your installed app is the version that applies to you.
