§ QUESTIONS FRÉQUENTES
Frequently asked questions
How does blockchain timestamping work?
+
We use the OpenTimestamps protocol which anchors the hash of your document in the Bitcoin blockchain. This creates irrefutable proof of your document's existence at a specific date, without revealing its content.
Is my file stored on your servers?
+
No. Your file is never uploaded. The SHA-256 hash is calculated locally in your browser, only this hash is sent to our servers.
What is included in paid plans?
+
Solo, Pro, and Team plans include a legal PDF certificate, proof history, and monthly quotas adapted to your volume.
Can I supplement a plan with credits?
+
Yes. Credit packs are used to absorb volume peaks without changing plans.
How long does it take to confirm a timestamp?
+
Submission is immediate, but blockchain confirmation generally takes 12 to 24 hours, the time for the proof to be anchored in the Bitcoin blockchain.
Can I cancel my subscription?
+
Yes, you can cancel at any time. You keep access until the end of the current period.
