Undeleter Recover Files & Data v4.92 (AdFree)

Scan for and recover deleted files from memory cards and internal storage on rooted devices.

The app uses rewarded video ads – restoration of any discovered file or data is completely free of charge. You can still buy the unlocker to remove all ads and enable background scanning.

Without root access, Undeleter can only scan app caches for images.

App caches can contain images that would not otherwise be discoverable: you may find photos that were shared with you on social media but you never opened, or lower quality copies of images you have now or have deleted in the past. They may also contain images that have been preloaded by your browser or other apps on your device – even images of people you don’t know. They can be filtered out using “Hide extant files”.

Deep scan heuristically scans for and recovers the following types of files: BMP, JPEG/JPG, PNG, MNG, JNG, GIF, MP4, AVI, MKV, MP3, OGG, OGM, WAV, FLAC, AMR, MP4A, PDF, SXD, SXI, SXC, SXW, ODT, ODG, ODS, ODP, DOCX, XLSX, PPTX, ZIP, JAR, APK, EPUB.

Data scanning is available for a select number of apps. Data will be recovered in the form of HTML files for WhatsApp and Viber, as third-party catalogs cannot be merged.

Shred/ secure delete – files found on free disk areas can be erased permanently in bulk using the Shred function. You can also use the system-wide Share menu to securely erase files directly through any other app, for example by opening the gallery, selecting a number of images, pressing the Share button and selecting Secure delete.

Permissions – all of these are necessary for various functions, this is not a time wasting game, its an app for adults that was written from the ground up to restore deleted data. Theres no catch, no trick. Read the instructions, Google the terms if you don’t understand them. You will get what you need if you pay attention to what you’re doing.

Google has decided to group many permissions in such a way as to make apps request all or nothing, leaving you to figure out what exactly is being used and why. In other words, you’re responsible for your own choices.

Nonetheless, you can check – thanks for that G – the details right here on the store page, where it says Permissions. Click on “View details” to see what is being used.

For the paranoid I point out that my actual home address can also be found at the bottom of this page, so if you feel you need further explanation, you’re welcome to come speak to me personally.

ACCOUNT – needed for Google Drive and Dropbox upload

PHONE – used to identify phone state and identity, specifically PHONE_STATE

CALL/ SMS – needed for the app data scanner – deleted messages and call logs

LOCATION – for ads, I don’t use Admob any more, which would extrapolate your location without your permission regardless
