VineBlocks is a free game made for children. Our privacy approach is simple: the safest data is the data we never collect. We do not build profiles of your child and we do not sell or share anything.
Information we do not collect from children
We do not collect or ask for any personally identifiable information from children. Children have no accounts and never sign in. We do not request a name, email address, age, birthday, phone number, photograph, or precise location from players. Player names are chosen from a fixed, curated list — free-text names cannot be entered.
Optional accounts — for parents and leaders only
Playing the game never requires an account. A parent or church leader may optionally create an account to manage dashboards, daily limits, or a group world. If they do, we store only: their email address, a one-way hash of their password (we can never see the password itself), an optional display name, and a login session. This is an adult’s information, provided with their consent — it never contains anything about a child. A leader may type a student’s first name into their roster; that first name is the only student-related text we store, it is entered by the adult (not the child), and it is tied to the leader’s account, not to any child account or identity. You can delete your account and its data by contacting us.
Information stored on your own device
To make the game work, we save your progress (your builds, inventory, and settings) in your browser’s local storage on your device. This never leaves your device unless you choose to use the optional backup below. Clearing your browser data removes it.
Optional anonymous backup
If you choose to back up your progress across devices, the game stores your save file on our server under an anonymous code that you choose and keep — like a coat-check ticket. This code is not linked to any name, email, or account, and we have no way to identify who it belongs to. The backup expires on its own if it is not used. Don’t share your code with anyone you don’t want to have your save.
Multiplayer data
If a parent turns on private multiplayer, the server relays only the minimum numeric data needed to see other players in the same private room: position, a colour palette, a chosen-name index (from the curated list), a pre-approved emoji index, and block-edit coordinates. No free text is ever transmitted. This data is relayed in real time between players in the room and is not used to build any profile. A short, anonymous activity log (join/leave times) may be kept on the device for the parent’s weekly summary; it stays on the device.
No advertising or third-party tracking
VineBlocks shows no ads and contains no third-party advertising, analytics, or tracking scripts. The game loads only from our own servers.
Children’s privacy (COPPA & similar laws)
VineBlocks is designed to be used by children and is built to align with the U.S. Children’s Online Privacy Protection Act (COPPA) and similar laws by collecting no personal information from children. Children have no accounts and never provide us any personal data. The only personal information we ever hold is an adult’s account email (and hashed password), created voluntarily by a parent or leader — which COPPA permits, because it is an adult’s own information, not a child’s. If you believe a child has somehow provided us personal information, contact us and we will delete it promptly. You may also request deletion of your adult account at any time.
Data security
The game is served over encrypted connections (HTTPS) under a strict Content-Security-Policy, and data is stored on Cloudflare’s infrastructure. We hold no personal information about children, so a breach could never expose a child’s identity. The only personal data we store is an optional adult account email and a one-way hashed password — passwords are never kept in readable form.
Changes
If this policy changes, we will update the date above. Material changes will be noted on this page.
