It helps to include which app you are using (Mac, iPhone, iPad or the web), what you were doing, and what happened instead. A screenshot is worth a paragraph.
Cancelling. You can cancel a paid plan at any time from Settings inside the app. Your plan stays active until the end of the period you have already paid for.
Deleting your account. Settings has a delete option that erases your account and every conversation attached to it. It cannot be undone, so download your data first if you want a copy.
Getting your data out. Settings can export your full account record as a file, including your conversations.
Starnexus sends your messages to whichever AI company runs the model you picked, and our Privacy Policy names each of them and says what they do with your data. It is worth reading if you have not.
