Prove your photos existedon the day, unchanged.
Take photos of a flat, a hire car or a parcel in this app. You get a free receipt. Later, anyone can check the photos existed, unchanged, by that day.
Your files never leave your phone or computer. We only receive the set's fingerprint, a code worked out from the files that can't be turned back into them.

How it works
- Take the photos in the appFollow the checklist. Your phone keeps each file exactly as taken.
- Finish, and get a receiptYour phone makes one fingerprint for the whole set, and it is independently timestamped, for free.
- Save it. Anyone can check it.Keep the zip somewhere safe. If there is a dispute, anyone can drop it into the checker. No account needed.
Free, for everyone
Leave your mark on a public record the whole world keeps.
Your set's fingerprint goes into a public record that is copied on thousands of computers around the world and has been running since 2009. Not even we can change the date afterwards, and anyone can check it with free, standard tools, without asking us.
Why is it free?
Thousands of fingerprints share one entry in that record. Free public timestamp services, run on donations, bundle them together and pay the small fee. We send them one fingerprint per set, never your photos.
How it works, in fullWhat 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.
