Terms of Service
Last updated October 19, 2026
In short: building your tree is free. Family Vault is an optional plan the keeper pays for so the whole family can share the tree. Your family owns its content. Be kind, and only share what you have the right to share.
Agreeing to these terms
By using Familynk (the app at familynk.io) you agree to these Terms and to our Privacy Policy. If you don't agree, please don't use Familynk. Questions: support@familynk.io.
Accounts
- You must be at least 13 to create an account.
- Relatives who open an invite link can join as a guest without an account, and can save their spot with Google or email later.
- Keep your sign-in details safe. You're responsible for what happens under your account.
- The person who creates a tree is its keeper. The keeper decides who is in the tree and what role they have.
Free plan and Family Vault
Building a tree is free: unlimited people, a photo on every person, notes, and one cover photo, private to you. Family Vault is needed to share the live tree with relatives (invite links to view or edit) and adds three cover photos and future extras.
| Yearly, renews every year | $11 / year |
| Monthly, renews every month | $1.99 / month |
| Lifetime, one payment, never renews | $79 once |
- The keeper pays. One plan covers the whole tree, and relatives who join through an invite never pay.
- Payments are processed by Stripe. Prices are in US dollars and may include tax where required.
- Yearly and Monthly plans renew automatically until you cancel. We'll tell you before any price change takes effect, and it will apply from your next renewal.
- Lifetime means for as long as Familynk operates.
Cancellation and refunds
- Cancel any time in the app under Plan, then Manage subscription. Family Vault stays on until the end of the period you've paid for, then the tree returns to the free plan. Your tree, people and photos are kept, and members already in the tree keep their access, but new invite links stop.
- Refunds: if you're not happy, email support@familynk.io within 14 days of your first payment for a plan (including Lifetime) and we'll refund it in full. After that, payments aren't refunded, except where the law requires otherwise or if we charged you in error.
- If a renewal payment fails, Family Vault pauses until the payment goes through.
Your family owns its content
- You and your family keep ownership of everything you add: names, relationships, photos and notes.
- You give us permission to store, copy and display that content only so we can run Familynk for you and the members of your tree. We don't use it for anything else, and this permission ends when the content is deleted.
- Only upload photos and information you have the right to share. Respect relatives who ask to be left out, and take extra care with details about living people and children.
- You can export your tree at any time from Settings.
Acceptable use
Please don't use Familynk to:
- post anything illegal, hateful, harassing, sexually explicit, or that exploits or endangers children;
- share someone's private information to embarrass, threaten or harm them;
- impersonate others or add people's photos without the right to do so;
- get into trees, accounts or features you weren't given access to, or get around Family Vault payments;
- upload malware, overload the service, or scrape or copy it with automated tools.
We may remove content or suspend accounts that break these rules, and we'll tell you why when we can.
The service
We work hard to keep Familynk running and your data safe, but it's provided "as is", without guarantees that it will always be available or error-free. Please export a backup now and then. To the extent the law allows, Familynk isn't liable for indirect or consequential losses, and our total liability is limited to what you paid us in the 12 months before the claim. Nothing in these terms limits rights you have under consumer law.
Ending your use
You can stop using Familynk at any time and ask us to delete your account or tree (see the Privacy Policy). If we ever shut Familynk down, we'll give you notice and time to export your trees.
Changes and contact
If we change these terms in an important way, we'll update the date above and let you know in the app before the changes apply. Questions: support@familynk.io.
