Terms of use

Last updated 21 October 2026. By using SumStreak you agree to these terms.

If you don't agree with these terms, please don't use SumStreak.

What this is

SumStreak is a free website with a daily timed arithmetic sprint, practice sets and a daily leaderboard. There is nothing to buy.

Play fair

Don't use scripts, bots or other tools to answer for you or to change your times. We may remove runs that look automated or impossible from the leaderboard.

Nicknames

Nicknames appear publicly on the leaderboard. Don't use one that is offensive, impersonates someone, or contains anyone's personal details. We may remove or change nicknames that do.

Your account

An account is optional. If you sign in with Google, keep your device secure; anyone using your signed-in browser can play as you. You can ask us to delete your account at any time (see the privacy page). Children under 13 should use the site without signing in.

Fair use

Don't try to break, overload or misuse the site or its servers, or use it to collect other people's data.

No warranty

The site is provided as is, without warranties of any kind, and may change or stop. Times depend on your device and connection, and the leaderboard is for fun. To the extent the law allows, we are not liable for any loss arising from your use of it.

Changes

We may update these terms. The date at the top shows when they last changed.
