About this app

The seal between you and betting.

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, 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. The seal opens only when the time YOU chose ends. That's the promise: in the moment of impulse, the decision was already made by your best self.

HOW IT WORKS
• Local network filter: blocks gambling sites in every browser. Everything happens on your phone — your browsing never touches our servers.
• App detector: closes casino and betting apps the moment they open.
• Seal protection: prevents the app from being uninstalled while your period is active.
• Blocklist updated daily, powered by community reports: if a site slips through, report it and we block it within 24 hours.

YOUR PROGRESS, WITHOUT SHAME
See your streak, the attempts the seal blocked for you, and the pattern of your hard moments. Every blocked attempt is a win.

HELP, ALWAYS ONE TAP AWAY
Your country's helplines, Gamblers Anonymous groups, therapist directories, and guides to ask your bank for gambling transaction blocks. All free and confidential.

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

Sello is a self-exclusion tool: 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.

Annual or monthly subscription via Google Play. Cancel renewal anytime: your sealed period keeps protecting you until it ends.
