Kibu

Data Retention Policy

Version 1.0.0-draftEffective 16 August 2026Updated 15 August 2026

How long Kibu keeps each kind of information, why we need to keep it that long, and what happens when the time is up. COPPA requires us to publish this, and we treat it as a specification our systems must actually implement — not a statement of intent.

Our principles

  • We set a period for every category. Nothing about a child is kept indefinitely.
  • Deletion means the record is removed from our database and the file is removed from our storage. It is not a hidden flag.
  • You can always delete sooner than the periods below. These are maximums, not commitments to keep things.
  • Where we need a record for accounting or legal-defence reasons, we remove everything identifying the child and keep only the figures.

When you ask us to delete sooner

When you delete a child's profile or your family account, we do not wait for the periods above. Everything about that child is deleted within 30 days, from both our database and our file storage.

The only exceptions are the consent records and the anonymised billing figures described above, neither of which identifies your child.

Backups are overwritten on a 35-day cycle. A deleted record can persist in a backup until that cycle completes, and is never restored to live systems.

Governance

A scheduled job runs daily and applies every period above. Its results are monitored, and a failure is treated as an incident.

Reviewed annually, and on any change to what we collect.

Owned by our Privacy Owner.
