Loading preferences…

Private by design.

When enabled, text on permitted pages is read to identify and highlight emotional language. Analysis runs locally in your browser; page text and results are not sent to textheat. No telemetry is used. Preferences and explicitly saved site hostnames stay in this browser’s local extension storage and do not sync with your browser account.

Manual shortcuts are available only in Manual mode. Configure them in your browser’s Extensions → Keyboard shortcuts.
