Hours by Color for Google Calendar
Published by Fruzzworks. Last updated: 26 October 2026.
What the extension reads. When you open Google Calendar (calendar.google.com), the extension reads the event times, colors and event text shown on that page, so it can add up hours per color and display them in a panel on the same page.
Where data goes. Nowhere. All processing happens inside your browser. The extension does not send calendar data, browsing activity or any other information to the developer or to any third party. It has no servers, no analytics, no ads and no account.
What is stored. Two things, both in Chrome's own extension storage: the client names you type for your colors, and the panel's settings (whether it is collapsed, where it sits, whether you closed the tip). The names are saved with Chrome sync, so if sync is on they follow your Chrome profile to your other computers, like your bookmarks. The settings stay on your device. No calendar data is stored: no event titles, times or ids.
Sharing. None. Data is never sold or transferred.
Bug reports. If the extension can't read the event times, it pauses its totals and offers a button that copies a short technical report to your clipboard. The report holds the extension version, the Calendar view and language, event counts and up to three sample descriptions with every letter and long number replaced. It never holds titles, names, emails or event ids, and it goes nowhere unless you paste it somewhere yourself.
Limited Use. The use of information received from Google Calendar pages adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements. Data is used only to provide the extension's single purpose, showing hours per event color, and for no other purpose.
Removing data. Uninstalling the extension removes its saved names and settings. To remove one client name, empty its field under Name colors.
Changes. If this policy changes, for example when paid features are added, the new version will be posted here with a new date.
