Terms of use
Last updated 28 August 2026.
Knock is free. Using it means agreeing to the following, which is deliberately short.
Use it reasonably
Do not use Knock to harass anyone, and do not try to break into other people's squads or to overload the service. Squads are for people who already know each other.
Your content
You keep whatever you type — a name, an emoji, a note on a knock. You give permission to store and show it to the squads you are in, which is the only way the app can work.
Availability
Knock is provided as it is, with no promise that it is always available or that a notification always arrives. Do not rely on it for anything that matters.
Ending it
You can delete your account at any time from Settings. Accounts used to harass others may be removed.
