H2 Kiosk Browser: Website Lock

H2 Kiosk Browser is a kiosk mode browser for Android tablets and other devices: it locks a device to a single website in full screen, and you control all your devices from your phone, in the shop Wi-Fi or from anywhere. Visitors use the site but cannot leave it or open other apps. No root, no ADB, no PC.

Use it as a self-service kiosk, check-in or feedback terminal, info screen or simple digital signage with your website: in shops, at reception and trade fairs, in restaurants, hotel lobbies, museums and waiting rooms.

REMOTE MANAGEMENT FROM YOUR PHONE
• Install our app H2 Kiosk Control on your Android phone, pair each tablet by QR code or pairing code (Central management in this app)
• Lock or unlock the kiosk, change the start page and allowed addresses, set opening hours, switch the screen off and on, reload the page
• See each device's status: kiosk on or off, current page, battery
• In the same Wi-Fi the phone connects directly. With Remote access (on after pairing) it also works over the internet, e.g. on mobile data
• Status and commands are end-to-end encrypted, our relay server only forwards them

WEBSITE LOCK
• Full-screen kiosk on the start page you enter
• Navigation lock, on by default: the whole website with all subpages, or only the exact start page
• Extra allowed addresses, wildcards like *.example.com
• Local addresses and http:// work too, for an intranet
• Links to other websites, e-mail and app links are blocked
• Downloads always blocked, file uploads off by default (can be switched on)

VISITOR SESSIONS
• Session reset after an idle time you set: cookies, sign-ins, form entries, cache and history are cleared, or keep it for staff
• Back to the start page after 1 to 30 minutes without a touch
• Optional restart button in a corner you choose

LOCKDOWN
• Home, Recents and Back never leave the kiosk
• Notification shade and power menu blocked while the kiosk runs (each can be switched off)
• Exit with your PIN: Volume Up 7 times, or 15 taps on one free spot (both adjustable)
• Restarts by itself after a reboot or power cut

SCREEN AND SCHEDULE
• Dim or dark screensaver, or a picture slideshow from a folder
• One dark period per weekday, e.g. 20:00 to 08:00
• Burn-in protection and orientation lock

BUILT TO RUN UNATTENDED
• Recovers after a browser engine crash, offline page that retries, nightly reload

WHAT IT NEEDS
• Android 9 or newer; remote access from Android 10
• An accessibility service, used only to keep the kiosk locked. It never stores or sends screen content
• Display over other apps, usage access, 3-button navigation
• The app is in English

DEMO AND FULL VERSION
Free to try with every feature, including central management. The demo kiosk shows a watermark and by default ends after 1 minute. Full version: one-time purchase per device, no account. Reinstalling on the same device restores the license by itself. After a factory reset, tap "Email support" in the app and add your Google Play order number: we move your license.

PRIVACY
No account, no analytics, no advertising, no crash reporting. What visitors see and enter goes directly between the device and your website. For the device license, the app sends a pseudonymous device ID to our license server in Germany. While pairing and with remote access on, the device connects to our relay server in Germany, which cannot read status or commands.

ACCESSIBILITY SERVICE DISCLOSURE
This app uses Android's accessibility service only to keep the device locked to your website while kiosk mode is running: it brings the website back when another app or a system window comes to the front, blocks the Home and Recents keys and closes the notification shade and the power menu, each if enabled. It does not collect, store or transmit screen content or any personal data. You can leave kiosk mode at any time with the exit gesture and your PIN.
