Blocking a specific site, word or app

Add your own entries to Always blocked or Always allowed, choose how each one matches, and block individual apps on a device.

Updated

Step by step

  1. Open Rules and find Always blocked

    Below the categories on the Rules page.

  2. Pick how the entry matches

    Choose Domain, URL, Keyword or Regex. The hint under the box shows what each one catches.

  3. Type it and press Add

    An entry on Always blocked takes effect straight away and shows In force.

The four kinds of entry

  • Domain.example.com blocks that site and every subdomain, such as shop.example.com, in every browser and app.
  • URL.reddit.com/r/example blocks that page and anything under it, while the rest of the site stays open.
  • Keyword.Blocks any address containing the word. On a PC that includes search queries and page titles.
  • Regex.A regular expression, matched against the whole address. For people who already write them.
On a phone, URL, Keyword and Regex entries work in the major browsers: Chrome, Firefox, Samsung Internet, Edge, Brave, Opera and DuckDuckGo. Other apps on a phone are filtered by whole site, so a Domain entry is the one that reaches them.

Always allowed

An entry here is never blocked, whatever the categories say. It is a hole you are cutting on purpose, so adding one waits out your rule cooldown; taking one off applies straight away. Always allowed wins over Always blocked if the two overlap.

Taking an entry off

Removing an Always blocked entry is a loosening, so it waits: the entry shows Stops blocking in and a countdown, then Ready with Apply and Cancel.

Blocking a single page you have visited

In Web history or Activity, the menu at the end of a row offers Block this page and Block the whole site. Both apply straight away and appear on the Rules page.

Blocking an app

Apps are blocked one device at a time. Open the device from Devices, go to its Apps tab, and choose Block beside the app. If it is open, it closes within a minute. Unblocking waits out your rule cooldown.

The same tab has Automatically block newly installed apps, which is off to begin with. The Rules page lists it for each device too.

On Windows a blocked app is closed whenever it starts. On a phone, Kellet sends it back to the Home screen. You can also block an app from the App usage page, or give it a daily limit there.

Common questions

Which kind of entry should I use?
Usually Domain: it covers the whole site in every app. Use URL when you want to keep a site but lose one part of it, and Keyword sparingly, because a short word turns up inside a lot of addresses.
Is there a length limit?
Entries can be up to 253 characters.
