Duplicate Photo Cleaner

Duplicate Photo Cleaner finds the photos you have twice, puts them side by side and lets you decide what goes. Nothing is deleted unless you pick it.

WHAT IT FINDS
• Exact duplicates — the same file, byte for byte, matched by a content hash.
• Similar photos — an on-device perceptual hash with an adjustable threshold.
• Bursts — shots taken within seconds of each other.
Every group tells you why it was grouped: "Identical file", or "Very similar, 3 bits apart".

YOU DECIDE WHAT GOES
• Nothing is pre-selected. There is no "select all" default.
• The app may suggest keeping the largest and newest photo. A suggestion is not a choice.
• A review screen lists exactly which photos will go and how much space that frees.
• Per-group and total reclaimable size are shown before anything is deleted.

DELETION GOES THROUGH ANDROID
• Photos go to the system Recycle Bin first, where Android keeps them for about 30 days.
• Android shows its own confirmation dialog. If you dismiss it, nothing happens and your selection stays.
• Permanent deletion exists, but it is a separate action behind its own confirmation.

ON YOUR PHONE ONLY
• Photos are analysed on the device. Nothing is uploaded, there is no account and no server.
• The app reads file names, sizes, dates and the pictures themselves, to compare them and nothing else.
• It asks for photo library access because duplicates can only be found by looking at the whole library. The system photo picker shows only photos you have already picked, so it cannot find copies you do not know about.
• If you share only selected photos on Android 14 and newer, the app says so and scans just those.

BEING HONEST ABOUT LIMITS
• "Similar" is a heuristic. It can group photos that are not really the same, and it can miss ones that are. You look, and you decide.
• This app does not promise a "safe" clean-up and never deletes on its own.
• On Android 10 and older there is no system Recycle Bin an app can use. On those versions the app will not delete anything: it shows you the duplicates and leaves the deleting to your gallery app.

ALSO IN THE APP
• Scan progress with a cancel button and results that fill in as it goes.
• A hash cache keyed to each file, so a second scan is quick.
• Folders to ignore, such as Screenshots.
• Tidy, the mascot, gets visibly lighter as you reclaim space — tied to the real bytes, not a timer.
• 31 app languages and a dark interface.
• Free with ads. A one-time purchase removes them.
