The short version

Privacy

DailyBrain has no account system, no analytics, and no server-side storage.

What is stored

One small, versioned JSON file in your browser's local storage keeps your scores, streaks, theme and timezone preference. It never leaves your device.

What is never stored

No email, no location beyond the timezone offset you effectively play in, no puzzle history uploaded, no keys, no personal identifiers. Your nickname stays empty unless you add it.

Advertising

DailyBrain is connected to Google AdSense (publisher ca-pub-5160043218907251): the Google adsbygoogle.js loader is included on this site so that advertising can be displayed. No ad placements exist yet — pages currently show no third-party ads.

When ads are shown, Google and its partners may use cookies and other identifiers to build a profile of your interests and show you personalised advertising, and may share anonymised, aggregated statistics. See Google's ads policy and privacy policy, and the Google Ads Settings page to control personalisation. Choices relating to advertising, cookies and consent are presented through the applicable Google mechanisms. A consent banner (consent management) is not configured on this site yet.

Controls

You can clear everything with the erase button on this page. You can export or import your local file at any time — imports are strictly validated and never overwrite without your say-so.
