We are always trying our best to avoid any crashes in the app.
If it nevertheless happens, we are very sorry and will do everything we can to solve the problem as soon as possible. You can help us detecting the source of the problem by describing the bug in detail (When exactly does the app crash? Does it crash after a certain action, e.g. upon opening or when adding a card?) and send it to us via firstname.lastname@example.org. In case Stocard displays an error message, please include a screenshot.
Please do not reinstall the app without registering an account first! Otherwise you might risk losing your data. Please make sure to either wait for the next update which will fix the problem or to only reinstall the app if you registered an account with Stocard first. This way you can ensure that your data can always be restored.
