Is there a limit for when I can sync with my phone to transfer the data?

What if I travel with an iPhone and stay 1 month without syncing? What about 1 week? What is the limit?

The internal memory of the ring should have a limit

Galaxy ring has 8 MB of onboard storage data. There's no official info about it but it can store around 3 (safely) to 4 days of data.
