Step by step
- Install the app
The phone needs Android 10 or later. Open the app and go through the three welcome screens.
- Choose Protect this phone
The app asks How will you use Kellet here? Choose Protect this phone. The other answer is for somebody supporting a partner; see below.
- Sign in with your Kellet account
Use Continue with Google or your email address and password. The phone adds itself to your account, named after its make and model.
- Turn on protection
The app asks for four permissions in turn: Network filter, Accessibility, Usage access and Device admin. Before each one it explains what Android will ask and what the permission does not allow. Notifications are optional, and only asked for on Android 13 and later.
- Choose the optional checks
Two switches follow: On-screen detection, and Check saved photos and videos. Both are off unless you turn them on. Then choose Protection is active - continue.
What each permission is for
- Network filter.Lets Kellet check the sites the phone connects to, in every browser and app. Android shows it as a VPN because that is the kind of permission it is; it is how blocking reaches every app.
- Accessibility.Lets Kellet see which app is open, read the address bar of supported browsers, and, if you turn on on-screen detection, look for explicit content on the screen.
- Usage access.Feeds the App usage page and daily app limits.
- Device admin.Makes Kellet harder to remove on impulse, and lets a lock from the Consequences page lock the screen itself.
Using a pairing code instead of signing in
If you would rather not sign in on the phone, choose Use a pairing code instead in the app. On a computer, open Enroll a device in Kellet and pick Android: it shows a QR code and the same code as text. Scan it, or type it in, and choose Link with this code.
If you start this and stop, the phone stays on your device list as Awaiting installation.
If you only want to support someone
Choose I’m here to support someone at the first question and sign in. Nothing on your phone is blocked or monitored, nothing is enrolled, and you do not need a plan. You see the people you support and what they have let you change.
