1Who we are

Filzen is developed by ALFA Dizayn (“we”). Contact: info@alfadizayn.com.

2What stays on your phone

To find duplicates, similar and blurry shots, screenshots, junk files and to let you search, Filzen builds an index stored only on your device:

  • file names, sizes, dates and the GPS coordinates already embedded in your photos;
  • analysis results: sharpness and quality scores, duplicate fingerprints, text recognised in photos and documents (OCR), the number of faces in a photo and face groups, and search vectors;
  • place names, looked up in a list of towns built into the app (no coordinates are sent anywhere);
  • your cleanup history and settings.

All of this is processed on your device with on-device models. None of it is sent to us or to anyone else. Face groups are computed and kept on your device only; we never receive biometric data.

3What leaves your phone, and when

  • Purchases (Filzen Pro): payment is handled by Google Play or the App Store; we never see your card. RevenueCat (RevenueCat, Inc., USA) processes a random anonymous app user ID and the purchase/transaction details to confirm your subscription.
  • Smart search (optional, off by default): when you turn it on, Filzen downloads its on-device search model (about 117 MB) from Hugging Face. Only the download request is made (which reveals your IP address to the host); no photos or queries are sent.
  • Photo map: by default the map is built into the app, works offline and contacts no server. If you choose the detailed map (streets and place names), map tiles are downloaded from OpenFreeMap (tiles.openfreemap.org, OpenStreetMap data). Like any map app, its server sees your IP address and which area of the map is on screen; your photos and their positions are never sent. You can switch back to the offline map at any time with the map’s layers button. “Open in Maps” hands the place you tapped to your phone’s map app.
  • Notifications: created on your device; nothing is sent to a server.

Filzen has no advertising, no analytics and no tracking, and does not collect crash reports in this version. We do not sell or share personal data.

4Permissions

  • Photos and videos: to analyse your library. Nothing is deleted without the system’s own confirmation dialog.
  • Photo location (media location): to read the GPS position stored in your photos for place names and the map.
  • Files: only files and folders you pick, to find leftovers and let you search inside documents.
  • Notifications (optional): weekly cleanup reminder and “on this day” memories.

5Deleting your data

  1. In Filzen open Settings → Erase Filzen data and confirm. This removes the index, analysis results, face groups, search data, downloaded models and settings from your phone. Your photos and files are not touched.
  2. Uninstalling Filzen also removes all of this.

Because we hold no copy of your library data, there is nothing on our side to delete. For purchase records, RevenueCat keeps the anonymous transaction history required for your subscription; you can ask us to request its deletion at info@alfadizayn.com.

6Retention

On-device data stays until you erase it or uninstall the app. Purchase records are kept by the stores and RevenueCat as long as needed for your subscription and legal obligations.

7Children

Filzen is not directed at children under 13 and does not knowingly collect their data.

8Your rights

Depending on where you live (for example under the GDPR or Turkey’s KVKK) you can ask for access, correction, deletion or restriction of your personal data and object to processing. Write to info@alfadizayn.com; we answer within 30 days.

9Changes

We may update this policy; the current version is always on this page with its date.
