What Happens to a Timestamp When a Subscription Ends?
Retention rules for files, certificates, hashes, TSA evidence, and blockchain records after cancellation.
Published 2026-08-12 · ProofIt Editorial
Direct answer
Original uploaded files are deleted 30 days after subscription cancellation. Certificate records remain accessible for 1 year. SHA-256 and blockchain records are permanent. TSA evidence is treated as permanent if you retain the token. Blockchain records are not deleted or reversed on cancel.
After the file is deleted
The certificate can remain accessible for the certificate window, but ProofIt can no longer verify the original file itself unless you provide the file again.
