Privacy Policy
Last updated: June 2026
Kin-Vine is a private, invite-only home for your family. Protecting your family's memories and information is the entire point of this service. This policy explains what we collect, how we use it, and the things we will never do.
Information we collect
Account details you provide: your name, family name, email address, and password (passwords are stored encrypted by our authentication provider).
Family content you choose to add: photos, videos, stories, milestones, events, and the relationships in your family tree.
Payment information: handled directly and securely by Stripe. We never see or store your full card number.
Basic usage data needed to operate and improve the service (for example, sign-in activity and feature usage).
How we use your information
To create and run your private family space, deliver the features you use, process your subscription, and send you account and service emails (such as confirmations, reminders, and updates you've enabled).
What we will never do
We do not sell your data. We do not show ads. We do not make your family content public. Your family space is visible only to the people you personally invite.
Who we share it with
Only the family members you invite can see your shared content. Behind the scenes we use trusted service providers strictly to operate Kin-Vine: Supabase (database and authentication), Stripe (payments), Resend (email delivery), and Vercel (hosting). They process data only on our behalf.
We may disclose information if required by law, or to protect the safety and rights of our users.
Children & families (COPPA)
Kin-Vine is an adults-first service. Children under 13 cannot create their own login; a parent, guardian, or family administrator creates and manages a profile on their behalf, and we do not knowingly collect personal information directly from a child under 13.
Teen access (ages 13–17) is enabled only by a parent or family administrator, who initiates the invitation. Teens receive limited access under continued family oversight and cannot create networks or change family structure.
At adulthood (18+), a person may claim ownership of their own profile. Throughout, a parent or guardian can manage, correct, or delete a child's profile and its data at any time by contacting info@kin-vine.com or using in-app controls.
Your choices and rights
You can access, update, or delete your information at any time, and you can cancel your subscription whenever you like. To request deletion of your account and associated data, contact us at info@kin-vine.com.
California privacy rights (CCPA/CPRA)
If you are a California resident, you have the right to know what personal information we collect, to access and delete it, to correct inaccuracies, and to not be discriminated against for exercising these rights.
Kin-Vine does not sell or share your personal information, and does not use it for cross-context behavioral advertising. To exercise any of these rights, contact us at info@kin-vine.com.
Security
We use industry-standard measures to protect your information, including encryption in transit (TLS) and at rest, role-based access controls so family content is visible only to invited members, and an audit log of significant changes to a family network. No system is perfectly secure, but safeguarding your family's memories is a core priority.
Changes to this policy
We may update this policy from time to time. We'll post the new date above and, for significant changes, notify you.
