Frequently asked questions
Answers to the questions we hear most. Can't find yours? Write to us.
Do you see the sites I visit?
No. The filter decides on your device and your history is sent nowhere. We only receive the unblock requests you choose to send.
Do I need to reset my phone?
Not for simple protection: AT Filter installs like an app. For full lockdown (no uninstall, no reset), the phone is reset once; we help you and back up your data first.
Can my child uninstall AT Filter?
Not silently: parents are alerted immediately. On Windows and with reinforced protection on Android, uninstalling needs a parent's approval from the console.
What about private browsing?
It is filtered like everything else: the same rules apply whatever the browser mode.
A site I need is blocked. What do I do?
Request it from the block page. The AT Filter team checks it and opens it for your household or for everyone. Parents can also open it themselves from the console.
Which devices are supported?
Android phones and tablets, Windows computers, and the Chrome, Edge and Brave browsers. iPhone, iPad, Mac, Chromebook and Linux are coming soon.
And on iPhone in the meantime?
The Install page explains how to set Apple's Screen Time to block adult sites and enforce safe search, with a passcode you keep.
How much does it cost?
The Essential plan is free. The Family plan is paid per device, with a discount from 2 devices and a 15-day free trial. See the Pricing page.
What happens if I stop paying?
Nothing is switched off: the household goes back to Essential. Adult sites stay blocked and safe search stays enforced.
Can I cancel any time?
Yes, with no commitment, from the console. The subscription ends at the end of the paid period.
Does AT Filter slow the Internet down?
No. The filter runs on the device: your connection takes no detour through a distant server.
Who decides which sites are open?
The AT Filter filtering team, following a written charter for each level. And always you, for your household: you can open or block a site at any time.
