Privacy Policy

Last updated: June 3, 2026

1. Data Storage & LocalStorage

Our weekly timetable generator is structured as a client-side application. We do not store your scheduled rotas, subjects, teacher workloads, or custom layouts on central servers. Instead, all data persistence operations are executed on your local web browser using the HTML5 LocalStorage API.

2. Shareable URLs & Security

When you click "Share URL", your timetable data is serialized, compressed (using LZ-String), and appended directly to the URL parameters. Opening this link reconstructs the state on the client's browser. We do not transmit or log these query strings, maintaining full data sovereignty on your device.

3. Third-party Advertisements

We reserve locations for Google AdSense or sponsored layouts. These platforms may utilize tracking cookies to display personalized ads based on your visitations. You can opt out of personalized advertisements in your Google Account Settings.
