Gamblocker: block gambling sites on your phone
Gamblocker blocks gambling and betting sites on your own phone, for people who want to quit gambling. You install it for yourself, set your own password and decide how strict it should be. Blocking is done by an on-device VPN filter; your traffic never goes through a remote VPN server.

Why Gamblocker?
Three layers of blocking
Gambling domains are blocked with DNS, TLS SNI and IP checks against a list of more than 340,000 domains.
Built to resist bypassing
It resists attempts to bypass it by turning off the VPN or Private DNS, and protection settings sit behind your own password.
Runs on the device
Blocking happens on the phone itself. Nothing is sent to the developer.
You stay in control
You choose the setup, the password and the strictness; protection can’t be switched off on an impulse.
What it does
On-device VPN filter
Uses Android’s VpnService to check connections on the phone itself. Traffic never passes through a remote VPN server.
Password gate
Protection settings sit behind the password you set.
Uninstall protection (optional)
You can enable Gamblocker as a device administrator; it must be disabled (behind your password) before the app can be uninstalled.
Second layer: Accessibility (optional)
If you turn it on, it can close a gambling site opened in your browser, or an app named after a gambling brand, even when the VPN is off. The app explains exactly what this layer reads before you enable it.
Progress
See how many requests were blocked and how many days you have stayed clean.
Optional AI check
Only if you enter your own Gemini API key are unknown domain names (never page content) checked with Google Gemini.
