Frequently Asked Questions
Q. I never received my login email.
A. Please check your spam folder. The Service uses no password — you sign in via a link sent to your email, so there's no "forgot password" flow to worry about. If it still hasn't arrived after a few minutes, please email us at the address above.
Q. What can I do on the Free plan?
A. Uploading images, text, and PDF files (up to 1GB), building the timestamp proof, and issuing a certificate (verification report) are all free.
Q. What's the difference between "Pending" and "Confirmed"?
A. "Pending" means the record has been submitted to a calendar server. "Confirmed" means it has also been incorporated into the Bitcoin blockchain. Confirmation can take anywhere from a few hours to about a day.
Q. How do I cancel a paid plan?
A. You can cancel anytime from "Plan" → "Manage Billing" on your account page. No further charges will occur after cancellation.
Q. Can the operator see the contents of my uploaded files?
A. Files are stored on Cloudflare's storage infrastructure. Only the SHA-256 hash value is sent externally to build the timestamp proof — the file itself is never transmitted externally.
