Private files. Public proof.

A public receipt for private files.

Untamperable creates verification receipts for important digital artefacts without uploading or storing the original file.

We don't store the file.

We don't prove the story.

We prove the state.

Privacy by design. You keep control. We keep no copies.

Evidence Packs

Prove a bundle existed in a specific state without exposing its contents.

Software Releases

Publish receipts for packages, builds, plugins, and installers without uploading the release.

Media & Creative Work

Record scripts, edits, images, footage, manuscripts, and creative outputs as they evolve.

Reports & Records

Attach verifiable receipts to reports, exports, AI outputs, business records, and decisions.

What Untamperable does not do

  • It is not cloud storage.
  • It does not keep your files.
  • It does not recover lost documents.
  • It does not prove that a claim is true.
  • It does not inspect your content.

It proves whether the file, folder, or pack matches the recorded thumbprint.

How it works

  1. 1

    Hash locally

    A cryptographic thumbprint is created on your device. Your file never leaves your control.

  2. 2

    Store the receipt

    The receipt can be signed, timestamped, and stored in a registry. Only the thumbprint is stored.

  3. 3

    Verify later

    Anyone with the file can verify it against the receipt to confirm it matches.

Current status

Untamperable is in early development. The first implementation will focus on DevMuse release receipts and Sentinel Trust Monitor integration.

Coming next

  • Public verification pages
  • Evidence pack manifests
  • Batch receipts & anchors
  • Professional PDF receipts
  • API & integrations
  • DevMuse release receipts
  • Sentinel Trust Monitor integration

Verify a File is coming soon.

No upload form is active yet. Untamperable will begin with local thumbprints, DevMuse release receipts, and Sentinel Trust Monitor integration.

Private files stay private. The receipt remains checkable.
