Privacy policy.

1. No data collection

trialgrids runs entirely in your browser. We do not collect, transmit, store, or process any data you enter into the tools. Your randomization parameters, study titles, visit names, and assessment marks never leave your device.

2. Local storage

The Time Table tool uses your browser's localStorage to auto-save your work between sessions. This data is stored locally on your device only and is never sent to any server. You can clear it at any time through your browser settings.

3. Analytics

We may use privacy-respecting, aggregate analytics (e.g. page view counts, referrer domains) that do not track individual users or collect personal data. No cookies are set for tracking purposes.

4. Advertising

trialgrids may display non-personalised Google AdSense ads to support free access. Google's ad serving does not use any data you enter into the tools. For Google's own privacy practices, see policies.google.com/privacy.

5. Third-party fonts

Fonts (Fraunces, JetBrains Mono, Inter) are loaded from Google Fonts. This may result in a connection to Google servers. See Google's privacy policy for details.

6. Changes

We may update this policy to reflect changes in the service. The date at the top of this page will reflect the most recent revision.
