Privacy Policy
Last updated: 2026-07-11
Blindfold is built so that your browsing stays yours. Blocking runs on your device, there is no account, and there is no Blindfold server that watches what you read. This policy explains that in plain terms.
The short version
- Blindfold has no user accounts and asks for no personal information to work.
- Ad and tracker blocking happens entirely inside Safari on your device.
- The on-device AI that learns new ads runs locally. Nothing it analyzes is uploaded.
- We don’t track you, sell data, or run advertising of any kind.
What stays on your device
Filter lists, the rules the AI writes, your custom rules, your allowlist, and your blocking statistics all live on your iPhone or iPad. Blindfold does not send your browsing history, the pages you visit, or your stats to us or anyone else.
What leaves your device, and why
- Filter-list updates. Blindfold downloads updated blocking lists over HTTPS from a public rules repository. These are ordinary file downloads; like any web request they expose your IP address to the host, but they carry no account or identifier for you.
- iCloud sync (optional). If you turn on sync, your settings and custom rules are synchronized through your own iCloud account by Apple. They are not sent to us and we cannot read them.
- Feedback (only if you send it). If you contact us from inside the app, the message you write, and your email address if you choose to include one, is transmitted so we can reply. We use it only to answer you.
- Purchases. Subscriptions and the lifetime purchase are handled by Apple. We never see your payment details.
