Canvas Helper does not collect, transmit, or store any personal data outside
your own browser.

The extension reads your existing Canvas LMS login session (already managed by
your browser) to make authenticated requests to Canvas's official REST API on
your behalf. Course and assignment data fetched from Canvas is shown in the
extension's side panel and is never transmitted to any external server.

The only information stored locally (in browser.storage.local) is your
last-used preferences: which Canvas instance you're connected to, which course
you last opened, and your filter text. This data never leaves your browser and
can be cleared by removing the extension.

The extension does not use analytics, advertising, telemetry, or third-party
trackers of any kind.
