Privacy

Your family's data is yours.

This policy explains what we collect, why, and what control you have. Plain English where the law lets us, formal where it doesn't.

Last updated: 2026-04-28

1. The short version

We don't show ads. We don't sell your data. We don't share your tree with anyone you haven't explicitly invited.

We collect what's needed to run the service, plus minimal anonymous analytics so we know what to fix. You can export or delete everything you've contributed at any time.

2. Information we collect

Account information: name, email address, password (hashed), profile picture if you choose to upload one.

Tree content you contribute: people, relationships, dates, places, photos, stories, recipes, and any custom fields you fill in.

Technical data: IP address, browser type, device type, pages visited, and timestamps. Used for security and debugging.

Cookies: a session cookie when you sign in, and a consent cookie that records your privacy preferences.

3. How we use your information

To run the service: render your tree, sync changes between collaborators, send transactional emails (sign-up confirmation, password resets, invitations).

To keep it secure: detect abuse, investigate suspicious activity, prevent unauthorized access.

To improve the product: aggregated, anonymous analytics tell us which features are used. We do not link analytics to your personal identity.

4. What we do not do

We do not show ads.

We do not sell or rent your data to anyone.

We do not share your tree with anyone you haven't explicitly invited.

We do not train AI models on your private content.

5. Sharing within your tree

Tree content is visible to people you invite as collaborators. You can set per-person and per-field visibility (e.g., hide health information from younger family members). You can revoke access at any time.

6. Your rights

Under GDPR, CCPA, and similar laws, you have the right to access, correct, export, and delete your data. You can do all of this from your account settings — no support ticket required.

If something doesn't work, email [email protected] and we'll respond within 30 days.

7. Data retention

We keep your data while your account is active. If you delete your account, we delete your data within 30 days, except where law requires us to retain billing records (typically 7 years).

Tree contributions you've made to other people's trees remain in those trees unless they remove them — you can no longer edit them yourself.

8. Security

Passwords are hashed with Argon2. Health data is encrypted at rest. Connections use TLS 1.3.

We can't promise perfect security — no one can — but we follow OWASP guidelines, run regular security reviews, and disclose breaches within 72 hours of discovery as required by law.

9. Children

Kinstripe is not directed at children under 13. Trees may include children's information added by their parents/guardians; that information is treated with the same privacy controls as any other person.

10. Cookies

We use a session cookie to keep you signed in, a consent cookie to remember your privacy preferences, and a small number of operational cookies for cross-site request forgery protection. We do not use third-party advertising or tracking cookies.

11. Changes to this policy

We'll email you at least 30 days before any material change. Minor changes (typo fixes, clarifications) update the date stamp at the top without notice.
