OkPicture analyzes your photos directly on your device using perceptual hashing — a technique that compares image content rather than just file names or sizes. This means it can detect near-identical shots, burst photos, and screenshots saved multiple times, even if they were taken seconds apart.

Your photos never leave your device. OkPicture operates entirely offline — no servers, no uploads, no cloud processing. All analysis happens locally using your iPhone's own processing power. We have no access to your photos or any data about you.

Photo library access is required to display your photos inside the app, identify duplicates and similar images, and delete the photos you choose to remove. We only use this permission for these core functions — never for data collection or tracking.

When you confirm a deletion in OkPicture, the photos are moved to the iOS Recently Deleted album, where they stay for 30 days before being permanently removed. This gives you a safety net to recover anything deleted by mistake.

Yes. Deleted photos go to the native iOS Recently Deleted album (in the Photos app under Albums → Recently Deleted) and can be restored within 30 days. After 30 days iOS permanently erases them.

Yes — fully. OkPicture has no network dependency. Scanning, reviewing, and deleting all work completely offline.

Most libraries scan in under 30 seconds. Very large libraries (10,000+ photos) may take a minute or two on older devices. The app will show a progress indicator while scanning.

The initial scan uses your device's CPU briefly, but OkPicture is designed to be lightweight. Once the scan completes, the app runs smoothly even on older iPhones.
