DialSpace stores user settings, groups, dials, notes, and related customization data locally in the browser.

When the weather feature is used, the add-on sends the city name selected by the user and related location query data to Open-Meteo services in order to retrieve weather information.

When favicon or icon lookup is used, the add-on may request icon images from third-party favicon or icon providers based on the website domain entered by the user.

DialSpace does not require account registration and does not intentionally collect, sell, or share personal data for advertising purposes.

User data remains in browser storage unless the user explicitly exports or synchronizes it using browser-provided features.
