The short version: FamilyLock has no accounts, no backend servers, and no analytics. Your data never leaves your own home network. We do not collect, store, or sell anything about you.
We do not run any servers, analytics, or trackers. The FamilyLock website is served by Cloudflare Pages, whose privacy policy applies to ordinary web requests (such as your IP address being logged briefly by the hosting provider). We do not read those logs for advertising or profiling.
The apps store and use information only on devices you control:
| Information | Where it lives | What it's used for |
|---|---|---|
| Pairing code and device address | On both phones, in the app's private storage | Mutual authentication between your parent and child phones |
| Child device name | On both phones | Displaying the device in the parent app |
| Screen-time usage and app list | On the child device; shared only with your parent phone over Wi-Fi | Enforcing budgets, list restrictions, and location checks |
| Location, battery level, charging state | Fetched on demand from the child phone to the parent phone over Wi-Fi | Showing you where the device is and its status |
FamilyLock is deliberately local. Nothing about your family, your devices, your location, or your apps is sent to us. There is no account to create, so there is no account data to protect or to hand over.
When opened, each app may fetch familylinker-apk.pages.dev/version.json to see whether a newer release exists. This request contains no personal data — only a web request to a static file, which your network and the hosting provider may log in the ordinary course.
If you use this software on a child's device, the personal data involved is used solely by you for the purpose of supervising that device. Please install it only where you have the right to do so, and be transparent with your family about monitoring in line with local laws and your own values.
Because data stays on the devices, you manage it directly:
Traffic between the two apps is authenticated with an HMAC-SHA256 token derived from your pairing code. No passwords are stored. Because enforcement is local, the main risk is someone on your own Wi-Fi; keep your home Wi-Fi secured and your pairing codes private.
We never touch children's data — it stays on the family's own devices. We do not offer an online service and therefore do not process children's personal data on any server.
If this policy changes, the new version will be posted here with a new effective date.
