Sello: stop gambling & bets

Start with a 7-day free trial. The seal between you and betting — the app to stop gambling when willpower isn't enough.

Choose a period —one week, one, three, six, or twelve months— and Sello blocks access to 264,000+ gambling sites and 214 apps on your phone: sports betting, online casino, slots, poker, bingo, roulette, and crypto gambling, licensed and unlicensed.

NO OFF SWITCH
Once sealed, the period cannot be shortened. Not by uninstalling the app, not by restarting your phone, not by writing to support. Your seal's clock lives on the server: reinstalling or resetting does NOT restart the period. The seal opens only when the time YOU chose ends. In the moment of impulse, the decision was already made by your best self.

HARD TO BYPASS (BY DESIGN)
Most blockers are easy to switch off mid-relapse — exactly when you need them most. Sello is built to resist that impulse: anti-uninstall protection, a server-side clock, and native app blocking, not just websites.

HOW IT WORKS — 3 LAYERS, 100% ON YOUR PHONE
• Network filter (local VPN): blocks gambling sites in every browser. It only filters DNS on the device — your traffic does NOT pass through our servers and it won't affect speed or location.
• App detector (Accessibility): spots the casino or betting app in the foreground and closes it. It only reads the name of the open app; it never reads or transmits your screen content.
• Seal protection (Device Admin): prevents uninstalling while your period is active.
None of these permissions are used for ads or analytics. Blocklist updated daily with community reports: if a site slips through, report it and we block it within 24 hours.

YOUR PROGRESS, WITHOUT SHAME
See your gambling-free streak, the attempts the seal blocked for you, and the pattern of your hard moments. One day at a time. Every blocked attempt is a win in your recovery.

HELP, ALWAYS ONE TAP AWAY
Your country's helplines, Gamblers Anonymous groups, gambling-addiction therapist directories, and guides to ask your bank to block gambling transactions. All free and confidential.

PRIVACY FIRST
Anonymous account, no email required. We never collect your browsing history. Filtering happens 100% on-device.

FAQ
Can I uninstall it if I change my mind? Not while the period is active — that's the protection.
Do I need an account? No, it works with an anonymous account, no email.
Does it affect speed or my location? No: the VPN is local and only filters on your phone.

Sello is a self-exclusion tool to stop gambling: one layer of protection that works best combined with professional support. If gambling is hurting you, you're not alone — find your country's helpline inside the app.
