No accounts, no personal data

BrainyWave has no sign-up and asks for no name, email, phone number or payment details.

Progress is stored on your device

Lessons completed, quiz scores, XP, streaks and drafts are saved in your browser’s local storage, on your device only. They are never sent to us or to anyone else. Clearing your browser data deletes them. We cannot see or recover them.

Cookies

BrainyWave itself sets no cookies. If web hosting or a statistics tool is added later, this page will say so.

Fonts

Pages load two typefaces from Google Fonts. When they load, your browser sends a normal web request (including your IP address) to Google’s font servers, as it would for any website using Google Fonts.

External links

Resource pages link to YouTube, TED, dictionaries and other websites. Those sites have their own privacy policies; we are not responsible for them.

Children

The Kids section is designed for children with a parent or teacher. Because no data is collected from anyone, no data is collected from children.

Changes

If this policy changes, the new version will be posted here with the date. Last updated: 6 October 2026.
