Cacher - Storage/Cache Cleaner のアプリ分析 11月4日

Cacher is a calm, honest storage cleaner for Android that helps you free up space. It finds large files, duplicate photos and app caches, shows exactly what is taking up room - real files, real numbers - and lets you decide what goes: you review the list and select what to delete. WHAT CACHER FINDS One "Scan" button looks for the files below and sorts them by how safe deleting is: "Definitely junk" (the only section with "Select all"), "Worth a look" and "Your call". • Large files and old screenshots, with size and age thresholds you set yourself • Duplicate photos and videos, matched by comparing the files themselves rather than their names • Similar photos - series of nearly identical shots - and blank shots: a black frame from a pocket, a shot into a lamp • The Downloads folder, sorted by type - app installers, archives, documents, photos, video and audio - plus older backup copies and messenger media • Empty folders, folders left behind by apps you uninstalled, APK installer files, and system leftovers such as .DS_Store, Thumbs.db and LOST.DIR APP CACHE, HONESTLY App caches are not part of the scan: they have their own item on the main screen, "Clear app cache". Cacher is a cache cleaner that works within Android's rules, which give no app the power to clear another app's cache: the only way is the "Clear cache" button on that app's own settings screen. On some phones Cacher taps it for you; on others the system keeps that button out of reach, so Cacher opens each app's storage screen and steps aside: you tap it yourself, and Cacher moves on once the cache has really shrunk. Cacher's hints leave the system buttons uncovered on purpose, so you tap the real button and read its real label. The only button Cacher presses on that screen is "Clear cache", so apps keep their data. HOW CACHER WORKS • Scan results, measurements, your settings and the cleanup history are kept in the app's own storage on your phone • Cacher cleans up storage and frees space - that is its whole job • Nothing is pre-selected for you, and anything that cannot be undone says so before it happens • "Cleared" appears only when the size really dropped. When a tap changed nothing, the report says that instead NON-MEDIA JUNK Some junk is not media at all, so the media library does not show it: empty folders, leftovers of uninstalled apps, stale installers, files left by other operating systems. The same scan lists every item with its size and path, and lets you mark anything as "Keep" so future scans skip it. CACHER+ Finding and deleting all of the above is free, in full; Cacher+ adds convenience and media squeezing. • Squeeze media - compress videos down to 1080p and shrink photos, keeping their dates and geotags. Seeing how much space it would save is free; the squeezing itself is the paid part, on Android 11 and newer • Automatic scans on a schedule, with quiet hours you set • Smart rules - quiet reminders when screenshots pile up or a cache grows • Storage history and analytics • Home screen widget and Quick Settings tile • App groups for cache cleaning • Extra color palettes and app icons PERMISSIONS, AND WHY • Usage access - the only way Android will tell an app how much space other apps occupy • Accessibility service - used for one fixed sequence: open an app's settings, tap "Storage and cache", tap "Clear cache". It reads those settings screens only while a cleanup or a check you started is running, and you can turn it off in one tap • All files access (Android 11 and newer) - folders and non-media junk are invisible to the media library, so without this access Cacher cannot find them • Photos and video - to measure the media library and find duplicates • Notifications - only so a scheduled scan or a smart rule can report quietly. What to delete is up to you Cacher works on Android 8.0 and newer. Where the platform does not allow something on your version, the feature is shown grayed out with the reason instead of quietly missing.
