Cleanse is a free, all-in-one phone cleaner and contact organizer that frees up storage and tidies your contacts — without ads that track you, subscriptions, or hidden paywalls. Everything runs on your device. Your data never leaves your phone.
★ SMART CONTACT ORGANIZER & DUPLICATE MERGE
Find and merge duplicate contacts in seconds. Cleanse detects duplicates by phone number, email, and similar names (even spelling variants like Mohammed/Mohammad), then safely merges them — keeping every phone, email, and note. Review each match side by side before merging, undo any merge instantly, and back up all contacts to a vCard first. It also flags incomplete and unreachable contacts so you can clean up your address book with confidence.
★ DUPLICATE & BLURRY PHOTO CLEANER
Reclaim huge amounts of space by removing duplicate photos and similar shots. Cleanse finds exact copies and visually similar images, plus blurry and low-quality pictures, keeps the best one, and lets you delete the rest in a tap.
★ APP LOCK (PIN & FINGERPRINT)
Lock private apps — messages, gallery, banking — behind a PIN or fingerprint. Your PIN is encrypted on-device and never uploaded.
App Lock uses Android's AccessibilityService API to work. When you enable App Lock and choose which apps to protect, the Accessibility service detects which app is currently in the foreground so Cleanse can show the lock screen over it. The service reads only the foreground app's package name — it does not read, log, collect, or transmit any screen content, and no data leaves your device. App Lock is optional and off by default; the Accessibility permission is requested only if you turn it on, and you can revoke it anytime in Android Settings.
★ STORAGE CLEANER & JUNK REMOVAL
Scan and clear junk files, app cache, thumbnails, old downloads, and leftover APK files to free up space fast. Schedule automatic cleaning and get storage-full alerts before you run out of room.
