Security & privacy

What we see of your files, where your data is, and how it's protected.

Proof of prior existence must never expose your creation. These articles explain what is computed at the time of deposit, what is kept, and how your files are protected.

Deposit data (contact details, fingerprint, date) is hosted in France and the European Union, and stored files are encrypted. Our team does not open them, except at your written request or when the law requires it.
