Privacy Policy

Brain Stretch ("the Service") is operated by Wisentech. We respect your privacy. This policy explains how we handle your information. In short: we collect almost no personal data.

What we collect

• Training records: Your scores and progress are stored only in your own browser's local storage and are never uploaded to our servers. Clearing your browser data deletes them.
• No account data: The Service requires no sign-up or login. We do not collect your name, email, or phone number.
• Anonymous analytics: We may use privacy-friendly analytics (e.g. Plausible) to understand overall traffic. Such tools use no cookies and do not track individual identity.

Advertising

The Service may display ads served by Google AdSense. As a third-party vendor, Google may use cookies to serve ads based on your prior visits. You can manage personalized advertising at Google Ads Settings.

Third-party services

If you choose to support us via Buy Me a Coffee, payment is processed by that third-party platform under its own privacy policy. We never access your payment card details.

Children's privacy

The Service is not directed to children under 13, and we do not knowingly collect their personal information.

Your rights

Because we store almost no personal data on our servers, you have full control over your local data and may delete all records at any time by clearing your browser data.
