Calendar Timesheet

Privacy policy

Effective 12 October 2026. Applies to the Calendar Timesheet add-on for Google Sheets, the ready-made Calendar Timesheet sheet, and this website.

In short. Calendar Timesheet runs inside your own Google account. It reads your calendars, writes to the Google Sheet you use it in, and sends nothing to us. The only data that ever leaves your Google account is your licence key, sent to Gumroad to check it. No analytics, no advertising, no tracking, no server of ours.

Who is responsible

Calendar Timesheet is published by Pierre Chevallier, entrepreneur individuel, France ("we"). Contact: support@calendartimesheet.com.

What the add-on reads from your Google account

Google dataWhat is readWhy
Your calendar listName, colour, time zone and identifier of each calendar you can seeTo let you choose which calendars hold billable time
Events of the calendars you choose, only for the periods being calculatedTitle, start and end, colour, "busy or free", event type, status, and the guests and organiser (email address, your own response, whether a guest is a meeting room)To count hours, match each event to a client by colour, calendar, title word or guest email domain, skip declined invitations, and count an event present in two calendars once
The spreadsheet you use it inOnly that spreadsheet (permission "current spreadsheet only")To write and update the tabs it creates and keep your notes and extra lines
Your email addressYour own addressTo send the monthly summary and alerts to you, and to tell your own response apart from guests'

The add-on never reads event descriptions, locations, attachments or video-call links, never reads your email, contacts or files, and never creates, edits or deletes a calendar event.

Where your data is kept

Everything stays in your Google account. We have no access to it and keep no copy. It is deleted when you delete the spreadsheet; removing the add-on's access at myaccount.google.com/permissions stops all reading and writing.

What leaves your Google account

Nothing else is sent anywhere. The add-on contains no analytics, no advertising and no third-party code.

Google API Services User Data Policy

Calendar Timesheet's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. Google user data is used only to provide the features described above, is never transferred to anyone, never used for advertising, never sold, and never read by a person.

Purchases

Licences are sold by Gumroad, which acts as the seller of record and processes your payment details, invoice and taxes under its own privacy policy. We receive from Gumroad the information needed to manage your purchase (such as your email address and what you bought), which we use only for that purpose and for support.

This website

This website sets no cookies and contains no analytics or tracking. Its fonts are served from this site. It is hosted on GitHub Pages; GitHub may log technical data such as IP addresses for security, as described in the GitHub privacy statement.

Support emails

If you write to us, we use your message and address only to answer you, and delete them within 24 months of the last exchange.

Your rights

Under the GDPR you may ask to access, correct or delete the data we hold about you (in practice, support emails and purchase records received from Gumroad), and you may complain to the French data protection authority, the CNIL. Data kept in your own Google account is under your control: you can edit or delete it at any time.

Changes

If this policy changes, the new version will be published here with its date. A change that widens what the add-on reads would require a new authorisation from you in Google's consent screen.
