The data associated with your STRNG account (your profile details, progress you make, and set information you record) is saved on our server.
However, if you initially subscribed with us on the App / Play Store, your subscription is linked to your account with Apple / Google. This means that you would be able to create multiple accounts on STRNG and have no trouble accessing any of them , as long as your device is still connected to the Apple / Google account used for your purchased.
If you cannot see your previous progress on the app, it is most likely that you are logged into a different account than before. It is important that every time you log back into the app you make sure to use the same email address to avoid this issue.
If you are not sure which email address you had used to create your main STRNG account, please submit a support ticket so that our team can investigate the matter for you.
