CaseStamp : Evidence Log

Build your paper trail.

Some things you only get one chance to prove. CaseStamp is your personal proof machine — whatever you need to capture, remember, or be able to show later, do it the instant it happens. Automatically timestamped photos and video, a communication ledger, and a clean exported report.

No accounts. No sign-up, ever. No servers. Nothing leaves your device. No analytics. Nothing tracked.

Available now on the App Store and Google Play.

Timestamped photos and video

Attach photos and video the moment they matter. Timestamps are locked at save time and can't be edited later. Video includes audio.

Tamper-evident by design

Every photo and video gets a SHA-256 fingerprint the moment it's captured. If even one byte changes later, it's detectable.

Communication ledger

Log who you talked to, when, and what was said — names, phone numbers, emails, and reference numbers in one place.

Exportable reports

Turn a case into a clean, chain-of-custody report you can copy, email, or export as a PDF for escalation.

Back up what matters. CaseStamp keeps everything on your device only — nothing is stored anywhere else. If the app is deleted, or your phone is lost, broken, or reset, anything you haven't exported is gone for good. Export a case to your own Google Drive, iCloud, or Dropbox, or email it to yourself — that copy survives no matter what happens to the phone. See backing up your cases for details.
