Security at Kibu
Version 1.0.0-draftEffective 16 August 2026Updated 15 August 2026
A public summary of how we protect your family's data. The full written programme is an internal document; this page tells you what it covers and how to reach us if you find a problem.
1. Our security programme
We maintain a written information security programme specifically covering children's personal information, as US children's privacy law requires. It has five parts.
- A named individual at Kibu is responsible for coordinating it.
- We assess the risks to children's data at least once a year, and whenever we change what we collect.
- We put safeguards in place against the risks we find, and record which safeguard addresses which risk.
- We test and monitor those safeguards regularly rather than assuming they work.
- We review and update the whole programme at least once a year.
2. Technical measures
- All traffic between the app and our servers is encrypted in transit.
- Data is encrypted at rest, including every photograph.
- Photographs are not publicly accessible. Retrieving one requires an authenticated request from the family it belongs to.
- Passwords are stored only as salted cryptographic hashes. Children's PINs are hashed the same way. Nobody at Kibu can read either.
- Sign-in attempts are rate-limited and repeated failures are locked out.
- Our logs are configured not to record children's content, photographs or location.
- Application secrets are validated at startup, so the service refuses to start rather than running misconfigured.
3. Who at Kibu can see your data
Access is limited to staff whose role requires it, granted individually rather than by default, and logged. We do not browse family content. Access is reviewed when someone changes role and removed when they leave.
Support staff resolving a specific issue you have raised see the minimum needed to resolve it.
4. Our service providers
Before any company handles children's data on our behalf we assess whether it can keep that data confidential, secure and intact, and we obtain written assurances that it will. That is a legal requirement and we treat it as a hard gate rather than a formality.
The full list, with what each receives and where, is at getkibu.com/subprocessors.
5. If something goes wrong
We have a written incident response plan. If a breach affects your family's data we will tell you what happened, what was affected, what we have done, and what you should do — in plain language, without waiting for a complete investigation.
We notify regulators within the time limits that apply: 72 hours in the UK and EU, and as required by SDAIA in Saudi Arabia and by state breach laws in the US.
6. Reporting a vulnerability
If you have found a security problem in Kibu, please tell us at [email protected]. We will acknowledge within 3 working days and keep you updated.
We will not pursue legal action against anyone who reports a genuine vulnerability to us in good faith, gives us reasonable time to fix it, and does not access, modify or retain other people's data while investigating.
Please do not test against real family accounts. Ask us and we will provide a test account.
The full policy set
This policy is one of 13. The rest cover children’s privacy, consent, retention, security, AI and the terms you agree to.
For parents
Privacy Policy
Kibu is a family app used by parents and by children. This policy explains what we collect, why, who we share it with, how long we keep it, and how you control it. Because most of our users are children, we hold ourselves to children's privacy rules everywhere we operate — not only where the law compels it.

For parents
Children's Privacy Policy
This is the notice required by the United States Children's Online Privacy Protection Act (COPPA), and it also serves as our children's privacy statement for the United Kingdom, the European Union, Saudi Arabia and the US states with children's design codes. It sits alongside our main Privacy Policy and, where the two differ, this one governs anything to do with a child.
/childrens-privacy
For parents
Parental Consent Notices
Kibu asks for your consent separately for each thing we want to do with your child's information, so that agreeing to one never silently agrees to another. This page holds the full text of every consent we ask for. Each is the notice referenced by the corresponding checkbox in the app.
/parental-consent
For parents
Data Retention Policy
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.
/data-retention
For parents
Terms of Service
The agreement between you and Kibu. It covers who may hold an account, what you are responsible for, subscriptions and refunds, and how either of us can end the agreement.
/terms
For parents
Cookies and Tracking
What the Kibu website stores on your device, and what the Kibu app stores on your phone. There is no advertising tracking anywhere in Kibu, and nothing at all is tracked on a child's device without a parent's verified consent.
/cookies
Parents and kids
Community Guidelines and Content Moderation Policy
What is allowed on Kibu, how we check, what happens when something breaks the rules, and how to report it. This is a safety document as much as a legal one — it exists because children can see what other children post.
/community-guidelines
For parents
Your Rights and How to Use Them
What you can ask us to do with your family's data, how to ask, what we need from you, and how long we take. Everything here is free, and most of it you can do yourself in the app without contacting us at all.
/your-rights
For parents
Service Providers and Sub-processors
Every company that handles your family's data on our behalf, what each one receives, where it is processed, and what we require of them in writing. We publish this because you cannot judge whether your child's data is safe without knowing who holds it.
/subprocessors
For parents
How Kibu Uses AI
Kibu uses AI in four places. This page says exactly where, what is sent, who receives it, what we forbid them to do with it, and what your child can and cannot do with AI. Children never talk to an AI in Kibu.
/ai
For schools
Kibu and Schools — FERPA and Student Privacy
Kibu is a consumer family product. We contract with parents, not with schools, and we hold no education records. This page explains our position on FERPA and US state student-privacy laws, and states plainly what we will not do.

Written for kids
Your Privacy, Explained
A version of our privacy policy written for the children who use Kibu. Required by the ICO Children's Code, which says information must be presented in a way children can actually understand — and by the EU's rules on protecting minors online.
