Effective Date: May 23, 2026
This Privacy Policy describes how “Brainstellar Progress Tracker” (the “Extension”) handles user data.
The Extension tracks your progress on Brainstellar puzzles. All progress data is saved locally on your device using Chrome’s local storage. We do not collect, store, or transmit any personal information, browsing history, or identifiable data to any external servers.
The locally saved data is used exclusively for the Extension’s core functionality: to display which puzzles you have completed and to track your current progress within the browser.
Because your data never leaves your device, we do not share, sell, or disclose your data to any third parties.
Since all data is stored locally on your device, you have full control over it. You can delete your progress data at any time by clearing your browser’s local storage or by uninstalling the Extension.
If you have any questions regarding this Privacy Policy, please contact the developer via the support tab on the Extension’s Chrome Web Store page.
