How can we help?

Most answers are below. If yours isn’t, write to us with your game, your DPI and what happened.

How long does a test take?

A quick test takes about 10 minutes, a normal one about 18 and a thorough one about 27. Every test adds to the same profile, so three quick tests on different days are worth more than one long one.

Which games are supported?

39 FPS games, plus a custom mode where you enter your game’s rotation yourself. Your result is also given in cm/360°, which works in any game. In Overwatch and Marvel Rivals, you also get a sens per hero.

The recognition check keeps failing

Check that the number you entered is your normal sens in that game: not a scoped, ADS or hero-specific value, and no typo. Check that the DPI matches your mouse software.

If it still fails, verify the rotation with the ruler-based 360° measurement under Settings.

Does Blindsens change my game settings?

No. Blindsens never reads or changes any game. It runs on its own, and you set the recommended sens in your game yourself.

Is my data sent anywhere?

No. Tests, profile and settings are stored only on your PC. You can export a backup, import it on another PC, open the data folder or delete your history under Settings. See the privacy policy.

What if the result says “no change can be proven”?

Then your current sens is already inside the range where the test can’t tell the steps apart. That is a real answer, not a failure. Another test on a different day will either confirm it or narrow it down.

Can I get a refund?

Purchases and refunds are handled by Steam under Steam’s refund policy.
