Google Docs Comments Exporter reads the comments of the Google Docs document in the current tab only when you click its icon. They are processed in your browser and only saved when you download a file or copy them. Nothing is sent to the developer. The only data sent is the email you enter to buy or restore Pro: it goes over HTTPS to our license server (lakeside-ext-api.expo.app), which asks Stripe whether a purchase exists and answers yes or no. Export options and the Pro state are stored in your browser. Full policy: https://lakesideapps.expo.app/extensions/privacy/
