Check a receipt
Anyone can check files against their receipt here, with no account. The checker works out each file's fingerprint again, checks the receipt adds up, and checks when it was independently timestamped.
Add the files to check
- the zip saved from the app, as it is; or
- receipt.json with the files from the zip's files folder; or
- one file with its .proof.json.
or drop them here
Your files are checked in this browser and never uploaded. To check the timestamp, the checker asks our server for the public records it relies on (and for the finished timestamp and the second record, if this copy hasn't got them), sending only the set's fingerprint and the records' own numbers.
What a receipt proves
A receipt proves that these exact files existed, unchanged, by the time shown on the receipt.
What it doesn't prove
- It does not prove that what a file shows or says is true, or that a scene was not staged.
- It does not prove who took the photos or made the files, or where.
- It is not legal advice. Whoever settles a dispute, such as a deposit scheme, a court or a hire company, decides what evidence it accepts.
How the checks work, step by step: how it works.
