Opera GX has a privacy-focused approach and does not collect personal data without user consent; however, it may collect anonymized usage data to improve the browser.

While Opera GX primarily functions as an online browser, certain features like bookmarks and saved settings can be accessed offline, but the full browsing experience requires an internet connection.

Users can cancel any subscriptions through their account settings in the browser or by visiting the Opera website, following the prompts for cancellation.

Opera GX does not require a subscription for its standard features, but it may offer premium features or services that could involve costs in the future.
