Frequently Asked Questions (FAQ)

1. Does MomentFold delete photos immediately?

No. MomentFold uses a safe, two-step deletion workflow:

  1. When you swipe or tap Trash, the photo is only marked as staged for deletion inside MomentFold. Your photo remains untouched in Apple Photos.
  2. Photos are only deleted when you open the Review screen and tap Purge. This prompts Apple’s official system confirmation dialog asking for your authorization.
  3. Once approved, the photos are moved to the standard “Recently Deleted” album in Apple Photos, where you can still recover them for up to 30 days.

2. Are my photos uploaded to external servers or AI services?

Never. MomentFold operates with strict, on-device privacy:

  • MomentFold does not upload your photos or videos. Apple Photos may use iCloud Photos according to your settings.
  • All AI and vision analysis (including aesthetic scoring and burst/variant detection) runs 100% locally on your device’s Apple Neural Engine and GPU using Apple’s native Vision framework.
  • MomentFold has no user accounts, no analytics tracking, and no external application servers.

3. What is the difference between Keep, Trash, and Archive?

  • Keep: Marks the photo as a keeper. If you enable “Link Keep with Photos Favorites” in Settings, it also favorites the photo in your Apple Photos library.
  • Trash: Stages the photo for deletion during your next Review & Purge session.
  • Archive: Marks the photo as reviewed and preserves it in Apple Photos, but clears it from your active culling feed.

4. How do I undo an action?

If you tap an action by mistake, simply tap the Undo button in the action rail to reverse your last decision. You can also view and edit staged decisions anytime before purging by visiting the Review screen from the More menu.

5. How does Daily Review work?

Open Daily Review from the feed menu, or Stats > This Week > “See every day”, to view the month-by-month calendar. Days use the photos’ capture dates, not the dates they were imported or added to your library. Tap a day with remaining photos to review that capture-date group. Once all photos from that day have been reviewed, the cell displays a completed checkmark.

6. How does duplicate and burst photo grouping work?

MomentFold automatically identifies photo bursts and near-duplicates using capture timestamps and on-device visual feature prints. In the feed, groups are collapsed into a stack with the highest-scored “hero” photo displayed on top. You can expand the stack to pick the best shot, or tap the options menu to ungroup photos if you prefer to evaluate them individually.

7. How does iCloud Sync work?

MomentFold offers an optional iCloud sync toggle in App Settings:

  • It synchronizes your app preferences and lifetime purge statistics across your personal Apple devices.
  • All synchronization happens through your private Apple CloudKit container (iCloud.net.yishanhe.momentfold.app).
  • No photos, thumbnails, or image metadata are ever sent through CloudKit.

8. Why does the storage savings number start with “~”?

The ~ means approximately. MomentFold totals the full resource size of photos staged for deletion and formats it in MB or GB. If optimized storage is enabled in Apple Photos, your device may keep smaller local versions while the originals remain in iCloud, so the space actually freed on the device can be lower than the number shown.

9. Can I browse a grid instead of full screen?

Current development builds offer Fullscreen and Waterfall layouts in Feed Settings. Waterfall lets you browse several photos at once and open one for closer review. This option may not yet be in your installed public beta.

10. Does Hold in Trash delete a photo later?

No. Hold in Trash keeps a photo out of Final Review until the hold expires. It never deletes automatically. Once eligible, the photo still needs your review and Apple’s deletion confirmation. The original stays in Apple Photos until you confirm deletion.
