Congrats on shipping. However, the "Privacy First" and "No Ads" claim gets eroded pretty quickly by cookies, and requests to trackers like n.clarity.ms, google-analytics and adtrafficquality.google. Note - I don't actually have an issue with any of those things - if you wanna monetize this service through analytics and ads, that's up to you. But it's at odds with your privacy first claims.

Earlier quoted context omitted.

The FileReader web API enables you to make local files available to content running in the browser. This entails a file picker and, depending on the verbiage in your browser UI, that may talk about "upload." That doesn't mean anything is being sent anywhere. See MDN: https://developer.mozilla.org/en-US/docs/Web/API/FileReader (Or that nothing is; I have not audited this code. But I vouched the parent comment to point…
