Privacy Policy
Last updated October 11, 2026
Manan is a mental training gym that runs in your browser. It has no accounts, no ads, no analytics and no tracking. This policy explains what the app stores and who else may see technical data when you use it.
What stays on your device
- Your exercise results: which exercise, when, score, accuracy, reaction time and counts of hits, misses and errors.
- Your preferences, such as day or night mode.
This is saved in your browser's local storage on your own device. Manan does not send it to any server. You can erase your results at any time with "Clear history" on the Progress screen, or by clearing this site's data in your browser settings. Because there are no accounts, there is nothing else to delete.
What Manan does not collect
Manan does not ask for or collect your name, email address, location, contacts, photos, microphone or camera. It does not use cookies, advertising identifiers or behavioural tracking, and it does not build a profile of you.
Third parties
- Fonts. The page loads its fonts (Poppins and Roboto) from Google Fonts. Your browser contacts Google to fetch them, so Google receives standard request information such as your IP address. See Google's privacy policy for details.
- Hosting. The page is delivered by a hosting provider, which may keep ordinary server logs (for example IP address and browser type) under its own privacy policy.
Music and sound
The relaxation music is generated inside your browser. No audio files are downloaded and the microphone is never used.
Children
Manan is a general-audience tool and does not knowingly collect personal information from anyone, including children.
Your choices
You can stop using Manan at any time, clear your history in the app, or clear this site's data in your browser. Your results are not stored anywhere else, so they cannot be recovered once cleared.
Changes
If this policy changes, the date above will be updated.
