Send a request with the subject “Account deletion” from the registered email address. Identity verification may be required. Export needed books before deletion.

Security reports

Use the subject “Security report” and explain the issue without exploiting it further or accessing other users' data.

CloseBook does not currently operate a separate public status page. Confirmed service incidents will be communicated through the product or support channel when practical.

Before public launch, the operator must configure and actively monitor [email protected]. A displayed but unattended support address is not acceptable.
