You can delete the account in the app, or ask us to delete it by email. This is the public deletion page for optionsloop.app, including the Android app.
Deleting the account removes the Google sign-in and the trade data stored for it (positions, history, wheel links, and sources). It does not cancel a Premium subscription. Cancel that in Google Play, the App Store, or, for a subscription bought on the website, with Manage Subscription, before or after you delete the account.
This is the same screen on the website, the iOS app, and the Android app.
Clear all trades (Account → Import & Export) removes trades and leaves the sign-in in place. Delete Account removes the sign-in as well.
If you cannot open the app, email optionsloopapp@gmail.com from the Google address on the account. Use the subject "Delete my OptionsLoop account" and say that you want the account and its trade data deleted.
We delete the Firebase Authentication user and the trade data stored in Firestore for that account within a reasonable time, except where we have to keep something to comply with law or resolve a dispute. We may reply to confirm we are deleting the right account. A request from a different email address needs enough detail for us to match it to the account, and we may ask you to write again from the Google address on the account.
Questions about this, or a request for a copy of your data, go to the same address. See the Privacy Policy for what the account stores and who receives it.
