Privacy Policy for Keepass Fidelity
App: Keepass Fidelity (net.helcel.fidelity)
Developer: Helcel
Effective date: 19 September 2026
What we collect
Nothing. We operate no servers and receive no data from the app. Keepass Fidelity has no internet access, no account, and contains no analytics, advertising, or tracking libraries.
Your data
Your loyalty cards (names and barcodes) are stored in the KeePass database you choose, not in a separate store controlled by us:
- Standalone mode: the app opens a
.kdbxfile you select, using the bundled KeePassDX engine. The file stays where you put it, encrypted by KeePass with your password or key file. - Keepass2Android plugin mode: entries are read and created through the Keepass2Android app installed on your device. That app holds the database and its own privacy policy applies to it.
Your database password is used only to unlock your database on the device. It is never stored anywhere by us and never leaves your device.
If your database file is kept in a folder synchronised by another app or cloud service, that service handles the file under its own privacy policy.
On-device cache
For quick access, the app keeps a recently-used history and may cache entry data in its private storage. You can mark individual entries to be excluded from caching, and the cache can be cleared from the app or by clearing the app's data in Android Settings.
Permissions
CAMERA— scanning a barcode to create an entry. Camera frames are processed on the device and are not stored or transmitted.READ_MEDIA_VISUAL_USER_SELECTED— reading a barcode from an image you explicitly select. Only the images you pick are accessed, and only while importing.
Retention and deletion
Cached data and history remain until you clear them or uninstall the app. Uninstalling does not delete your KeePass database, which is your own file: delete it yourself, or remove entries through the app or any KeePass client.
Children
Keepass Fidelity is suitable for all ages and collects no data from any user, including children.
Security
Your cards are protected by KeePass encryption, which depends on the strength of the password or key file you choose. On-device cache and history are held in the app's private storage, protected by the Android sandbox.
Open source
Keepass Fidelity is released into the public domain under the Unlicense. The full source is available at https://github.com/helcel-net/keepass-fidelity, so these statements can be independently verified.
Changes
Any change affecting privacy will be published in this document before or with the release that introduces it.
