SwipePicAway is made by one person, and every message gets read. Before writing in, the answers below cover the questions that come up most.
Can the app delete photos without me noticing?
No. Photos you swipe away are only staged in the app's trash bin. Nothing is removed from your library until you tap Delete and confirm the system dialog iOS shows on top. Even after that, iOS keeps deleted photos in the Recently Deleted album for around 30 days, where you can still recover them.
I swiped a photo away by mistake. How do I get it back?
While you're still in the deck, tap the undo arrow to take back your last decisions. Later on, open Profile → Trash Bin, select the photo, and tap Restore — it returns to its place, unsorted, as if nothing happened.
Why does a photo show "~" next to its size?
The tilde marks an estimate. Photos stored in iCloud but not downloaded to your device don't report their exact file size, so the app estimates it from the photo's resolution or the video's length until the real number is available.
Some photos don't appear in my decks. Why?
Photos that can't be deleted from this device — like items in iCloud Shared Albums or photos synced from a computer — are left out, since sorting them would have no effect. If you gave the app access to only a selection of photos, everything outside that selection is invisible to it; you can manage the selection from the banner on the Home screen or in iOS Settings.
How does duplicate detection work? Is it safe?
The scan runs entirely on your phone using Apple's on-device image analysis, grouping shots that look nearly identical so you can pick the keeper. No photo leaves your device, and the scan never deletes anything on its own.
Does the app upload or back up my photos?
No. The app makes no network requests at all. Read the privacy policy — it's short, because there's nothing to disclose.
