What to include
Bug reports are much easier to fix with these, and you can paste them straight from the app under Settings → About:
- Your phone and OS version.
- The app version.
- What you did, what happened, and what you expected instead.
Please do not send screenshots containing anything you would rather we did not see. We do not need your training data to fix most things, and if we do need it we will ask.
Things we cannot do
- Refunds. Apple and Google take the payment and issue the refunds; we never see your card. Ask them and you will get an answer faster than we could give you one.
- Cancel your subscription. Also in your Apple or Google account settings.
- Recover a phone you no longer have. If you were not syncing, your training was only ever on that device, which is the deliberate trade the app makes. Exporting from Settings → Your data is the way to keep a copy.
Security
If you have found a vulnerability, email devlazarbusiness@gmail.com with “Security” in the subject and please give us a chance to fix it before publishing. We will credit you if you would like us to.
Data requests
Export and deletion are buttons in the app rather than requests you have to make — the privacy policy explains where. For anything else, including access and correction requests, email us.
