FlickrSyncr

FlickrSyncr silently monitors your selected device folders and uploads new photos and videos to your Flickr account in real-time — the moment a new photo is detected, it is queued and uploaded automatically.

- Real-time folder monitoring — new photos and videos are detected the instant they are created and queued for upload automatically
- Custom folder support — monitor device photo albums and arbitrary filesystem folders side by side
- Continuous background sync — the upload queue drains itself item by item with no user interaction required
- Upload queue management — view pending, uploading, uploaded, and failed items with live progress
- Duplicate detection — MD5 hashing prevents re-uploading files already on Flickr, even on a fresh install on a new device (via Flickr machine tags); videos use a strengthened hash (first + last 1 MB + file size) to avoid false collisions
- Album (photoset) management — browse, create, and set a default upload album; new albums use a Flickr logo cover image
WiFi-only mode — optionally restrict uploads to WiFi connections to save mobile data
- Privacy control — choose public, friends-only, or private visibility per upload
Upload progress notifications — real-time progress, completion, and error notifications
- Automatic retry — failed uploads retry automatically up to the configured limit
- Unsupported format filtering — WebP and other formats not accepted by Flickr are skipped gracefully
- Media browser — browse your camera roll with upload status badges, filter by type or upload state; ignore individual items to hide them from all tabs without deleting files; "Upload All" on the Not Uploaded tab to enqueue everything in one tap
- Security hardened — TLS hostname validation for Flickr domains, CSRF-protected OAuth flow, proper XML parsing, and sensitive data guarded from non-release logs
- Optimized scanning — batch database lookups, paginated media loading, and background isolate file hashing for smooth performance with large photo libraries
- Settings — per-folder selection, default album, privacy, WiFi-only, auto-delete after upload (immediately or after 24h) with batch "Allow all / Deny all" system dialog, privacy policy, and more
