Retention Policy
Last updated: 1 November 2025
1. Snapshot at Issuance
Retention is set per verification at the time of issuance, based on your active plan at that moment. Upgrading or downgrading later does not retroactively change existing certificates.
2. Default Durations
- Free: 7 days
- Pro: 12 months
- Legal: 3 years
Durations can be updated for future verifications. Existing certificates keep the retention set when they were created.
3. Deletion
After the retention deadline (RetainUntilUtc) the certificate and associated artifacts may be permanently deleted
by automated processes. Backups are rotated on a schedule and will also expire.
4. Notifications
We may send optional reminders before expiry where enabled. Keep your email current to receive notices.
5. Exceptions
We may retain certain records longer as required by law, to resolve disputes, or to enforce agreements.
