Is Floating Scientific Calculator safe?

Low risk

Floating Scientific Calculator sends current-page Sentry telemetry after page-triggered extension messages.

The extension runs a content script on all sites and accepts page messages for its floating-calculator handler. When a page sends an unhandled action, the extension logs a Sentry event that can include the current page URL and recent click or keypress breadcrumb metadata, but not typed field values.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Where it sends data

Destinations our analysis observed Calculator contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
