Privacy policy
Last updated: October 18, 2026
At a glance:Blyc processes your photos, videos, queries and search index on your device. It has no account system or backend and collects no usage analytics. Public model and map data require downloads; iCloud media may also require a connection.
1. Information Blyc processes
| Information | Purpose | Location |
|---|---|---|
| Photos and videos | Understand visual content on-device, build an index and display results | System photo library; Blyc does not upload your media |
| Search index | Retrieval data computed from photo content for description-based search | App storage; not uploaded to any server |
| Location metadata | Coordinates in photo metadata, used to identify the city where a photo was taken | Processed on-device and stored within the app, excluded from iCloud backup |
| Search text | Compared with the index on-device | Not saved or sent |
| Voice | Transcribed on-device by the system, on supported devices and languages | No audio recording is retained or sent |
2. When Blyc connects to the internet
| When | Service | What the provider can see |
|---|---|---|
| Downloading the search model during setup | Public model hosting platform | A standard download request, without photos or personal content |
| Downloading city names for city search | Public GeoNames data | A standard download request, without personal content |
| Downloading boundaries for city search | Public Overture Maps data | Requested map tiles, revealing the approximate regions of photos in your library; no photos or exact coordinates |
| Viewing or sharing photos stored only in iCloud | Apple iCloud | Handled by the system under Apple’s privacy policy |
Once model and city data are ready, indexing and search can work offline with locally available media. You can disable city search in settings to stop boundary downloads. Providers receive your IP address as part of normal network communication. Blyc adds no other identifiers.
3. Permissions
- Photos: Access the library to index and display results, and perform actions you request such as favoriting, adding to albums or deleting. Deletion requires system confirmation and moves photos to Recently Deleted.
- Microphone and speech recognition: Used only for voice search.
- Network: Used for the downloads listed in section 2.
4. Exporting the index
You can export the search index in settings. The file contains retrieval data, without photos, filenames, capture times or locations. You choose its destination in the system share sheet. Blyc does not upload it automatically.
5. Deleting data
Deleting Blyc removes its model, index and city data without affecting your photos. Reindexing all photos in settings only clears and rebuilds the index.
6. Children
Blyc does not collect personal information or offer features for children that require it.
7. Changes to this policy
If data handling changes, this page and its date will be updated. Material changes will be described in app release notes.
