When the app was written over 10 years ago it used a now outdated storage that Google/Apple now require the device storage to be reset. The only fix that does not risk user data is to make a new app that uses new storage polices. This is currently being worked on but wont be released until January 2027. The best way to secure your information is to make sure your signed in and check the last backup date on home page or settings page. If you app is not backing up please contact us before updating.
