# Freeroll > Freeroll is an iPhone gambling blocker that uses Apple Screen Time to shield selected apps and a Safari content blocker to filter gambling websites locally. The Safari extension covers 7,000 gambling domain roots when enabled. A separate ManagedSettings filter can cover up to 490 prioritized roots with expanded browser coverage. Freeroll uses no VPN tunnel and uploads no cloud browsing logs. The Safari list includes US sportsbooks and daily fantasy sites such as DraftKings, FanDuel, BetMGM, Caesars, bet365, PrizePicks, and Underdog Fantasy. Canadian coverage includes PlayAlberta and PROLINE. Offshore and crypto coverage includes Stake and Roobet. Device blocking complements state and provincial self-exclusion programs, whose scope depends on the operators they cover. For example, iGaming Ontario’s BetGuard covers regulated online gambling in Ontario. ## Official pages - [Freeroll for iPhone](https://www.freerollapp.com/): Setup overview, browser coverage, bankroll calculator, and early access. - [Privacy policy](https://www.freerollapp.com/privacy/): Local data, Apple permissions, and optional schedule requests. - [Terms](https://www.freerollapp.com/terms/): iOS subscriptions, trial conditions, and cancellation. - [Support](https://www.freerollapp.com/support/): Safari setup, purchase restoration, and regional gambling helplines. ## Optional - [Full product reference](https://www.freerollapp.com/llms-full.txt): Architecture, blocking scope, cooldowns, and privacy.
