Pre-wipe evidence / Android

Know what made it
before you move on.

Compare the folders on your phone with a USB drive, synced WebDAV folder, S3 download, or saved manifest. Get a dated, portable receipt—not another backup promise.

Inspection desk / 01

Build a coverage receipt

Choose matching folder roots. We read filenames, sizes, dates, and file content only long enough to hash them in this browser.

Original evidence

Choose the phone folder

Select a folder such as DCIM, Download, or an app’s export folder.

No source selected

Backup evidence

Choose the matching destination

Pick the copied folder on USB/local storage, or import a manifest made on the destination.

No destination selected
Your files do not leave this screen.

Start with the source folder. Large files use a disclosed sampled fingerprint to protect memory and battery.

Method / 02

Evidence, not access.

  1. 01

    You point to folders

    Android’s file picker controls what this app can read. Protected app data stays protected.

  2. 02

    Your browser fingerprints files

    Small and medium files use full SHA-256. Files over 32 MB use clearly marked, low-memory sampled SHA-256.

  3. 03

    You keep the receipt

    Export JSON for machine-readable evidence or CSV for inspection. No account is required.

Scope / 03

This does not back up your phone.

It verifies user-selected photos, downloads, documents, and app-export folders. It cannot see protected app data, messages inside apps, system settings, or anything you do not select.

Matching filenames and bytes are strong evidence, not a guarantee that a remote provider will retain them forever. Keep two copies of irreplaceable files.

Optional / Migration Kit
