Your data and privacy

Where your information lives, how to clear it, and what permissions the extension asks for and why.

The short version

No account, no server, no ads, no analytics.
Your shifts, calendar data and settings stay in your browser's extension storage.
Nothing is sent to the developer.

The full legal wording is in the Privacy policy. This page explains what it means in practice.

What's stored on your computer

Shifts you approved or added, and inservices.
Busy time made from your calendar (event titles, dates and times).
Events waiting in Review.
Your settings (theme, colors, font, scenes, filters, and the city for Live weather if you use it).
If you link an account, the sign-in token the provider gave (and for Microsoft, the account's email so you can tell which is linked).
Calendar links you added. Treat these like passwords.

Data doesn't sync between computers. Removing the extension erases all of it.

What can leave your computer

When	Goes to
You link and scan Google or Microsoft	That provider, to read your events straight into your browser
You add a calendar link	The address you pasted, now and every hour
You turn on Live weather and allow it	Open-Meteo: the place name you type and the coordinates of the place you pick

Data & reset

Settings → Data & reset has four buttons. Each asks for confirmation inside the popup (never a pop-up dialog that can be cut off) and shows an Undo toast where applicable.

Button	Removes	Leaves alone
Clear saved shifts	The shifts on your Shifts tab	Availability and Review items
Clear availability	All busy time, calendar-detected and manual	Shifts and Review items
Reset all settings	Dark mode, text size, colors, font, theme and scene effects go back to defaults	Shifts, calendar link and availability
Clear all saved data	Saved shifts, availability, Review items and the removed-from-calendar list	Your calendar link and settings

To disconnect an account, unlink it in Calendar settings. That deletes the stored token and revokes it with the provider.

Permissions, in plain English

Permission	Why it's needed
storage	To save your shifts and settings in your browser.
identity	To open the sign-in window when you link Google or Microsoft.
alarms	To refresh your calendar links once an hour.
Subbook site access	To add the search and filter bar, apply your look, and fill the form. It does nothing on other sites.
Google and Microsoft calendar access	Only if you link an account, to read events. Read-only.
Open-Meteo	Only if you turn on Live weather.
Other sites (asked at the time)	When you paste a calendar link to a site Bettersubbook doesn't know, your browser asks permission for that one site.

The Google permission is the narrowest that works for reading events: calendar.readonly. Bettersubbook's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
