Does the app upload my photos anywhere?
No. All analysis runs on the phone, and the results sit in the app's own database on the phone. There is no account and no server to upload to. The Privacy page lists each kind of data and where it lives.
Does the app delete photos on its own?
Never. It only pre-selects what it is sure of, and nothing is deleted until you press Delete and confirm on the system's own dialog.
What if I delete something by mistake?
On iPhone, open Photos → Recently Deleted; photos stay there for 30 days. On Android 11 and later they go to the system trash (unless you chose "Delete permanently" in the app's Settings). On Android 7.1 to 10, and for anything in Files, deletion is immediate — the app says so before you confirm.
Why is my storage not free yet after cleaning?
Because the photos are sitting in Recently Deleted or the trash. Empty it (on iPhone the app has a button that opens Photos for you) and the space comes back.
Can I let the app see only part of my library?
Yes. Choose "Limited Access" on iPhone, or "Select photos" on Android 14 and later. The app sees only what you picked, and has a "Select more photos" button when you want to widen it.
Does scanning drain the battery?
Background scanning only runs while the phone is charging. When you open the app, scanning runs straight away but pauses in Low Power Mode, under 20% battery when not charging, or when the phone runs hot.
How is the Google Play edition different from the full Android edition?
The full edition adds Files — APKs, junk, duplicate and large files across the whole storage — because it is granted All files access. The Google Play edition cleans photos and videos the same way, and finds duplicate and large files in a folder you pick. Both share one app ID, so one replaces the other rather than installing side by side.
Which devices does it run on?
iPhone and iPad on iOS 15 and later, Android phones and tablets on 7.1 and later. Vietnamese and English, following the phone's language.
