Certmill stores account emails, hashed passwords, and the building/certification data you enter. We do not sell it. Session cookies only. Contact: hello@certmill.com.
Data retention: if a paid subscription ends, your account drops to the free plan and everything you entered is kept, so you can pick up where you left off. Accounts on the free plan with no activity for 12 consecutive months are deleted automatically, including buildings, certification records, and uploaded documents. This deletion is permanent. Delete your data yourself at any time by emailing hello@certmill.com.
Paid plans are billed monthly through Stripe and renew automatically each month until canceled; cancel anytime by emailing hello@certmill.com. Certmill assembles public government requirements as an evidence and tracking tool. It is not legal advice or professional compliance certification. Verify requirements with the responsible agency.
