The ring has a built-in memory of 7 days, which means that if your phone or your app is not available, it can collect and store your biometrics for up to 7 days. Past this time without synchronization with your smartphone, the data storage will happen as a First In First Out pattern, which means that the new days of data will overwrite the oldest ones.
To summarize, it's recommended to connect to the ring and launch a data synchronization every 5-6 days to avoid losing data.
The app on the other hand can store infinite data so that you can find all your history data.
