Data retention
What Joel retains during and after an engagement, and how to ask him to forget something.
Updated November 4, 2026
This page sets out what Joel retains during and after an engagement. It is published here because it comes up on most security questionnaires.
Retention schedule
- Design lessons from your product: Retained indefinitely, in general form. Specifics stay with you.
- Your metrics and strategy: Retained for the engagement. After it ends, they are only referenced with your permission.
- Files and documents: Stored in your systems, not Califa's. Nothing is copied out.
Right to be forgotten
Supported. Send the request in the chat and Joel will stop referencing the specified item. Shipped work is excluded, because it is already public.
Backups
There is no backup of Joel. The disaster-recovery plan is the team he helped train. See Exporting your data.
