Privacy first

Private by design.

No account

Nothing to sign up for, so there is nothing tied to your name.

No reports

Purus sends no reports or screenshots to a partner, a parent, or anyone else.

On your device

Filtering decisions happen on your phone. Your history, bookmarks, and tabs stay there. Purus doesn't operate servers that collect your browsing history or search queries.

Focus and self-mastery

Protect your attention.

For anyone building better habits, in work, in training, or in life.

Your attention, back

If late-night scrolling leaves you foggy and unmotivated, you want your focus and drive back, and a browser that helps you keep them.

A filter you can switch off at 11 p.m.

Inside Purus there's no toggle for the filtering, so a weak moment can't undo a good decision.

Things you already do on your phone

It's just a browser: search, read, shop, work. It's built so normal sites keep working.

Integrity and family

Protect what you value most.

Whether the reason is faith, marriage, fatherhood, or personal conviction, wanting your phone to match your values is not something to be ashamed of. Many people want protection without accountability software that reports on them. Purus is the opposite: a quiet tool that works for you, on your phone, without telling anyone.

It's one layer of a bigger effort, not a cure-all. No filter is perfect, and Purus significantly reduces exposure to explicit content but cannot guarantee complete filtering of all online content.

Questions

Straight answers.

Not inside the app: there's no toggle for any of the filtering. The two ways around it live outside Purus, which are opening another browser and removing DNS protection in iOS Settings. If you want a firmer line, a Screen Time passcode you don't know (or one a trusted friend holds) can lock those down. No setup is airtight, and we don't claim otherwise.

No. There is no account and no reporting. Purus sends no reports or screenshots to anyone.

No. Your history, bookmarks, and tabs stay on your phone, and PurusAI's image checks run on your device; no image or screenshot is sent to Purus or any third party. A few things leave your device in limited ways: Purus fetches updated block lists, DNS protection (if you turn it on) sends domain lookups through AdGuard's family filter, tapping ‘Report it’ submits that one URL to us, and Search Suggestions (if you enable them) send partial search text to your search engine. See the Privacy Policy for each.

The app appears on your home screen as “Purus”. Subscriptions are processed by Apple, like any App Store purchase.

Most filtering happens instantly on your device; DNS filtering can add a small delay the first time you visit a new site. If a legitimate site is blocked, tap 'Report it' on the blocked page and it's usually cleared in the next filter update. We haven't published battery measurements and won't quote a number we can't back up.
