Is it possible to get a seasonal pass?

or, if I only pay for 4 months a year, what happens to my data the following year?

A seasonal subscription is not currently available — the subscription is continuous (monthly or annual).
If you suspend your subscription, your account and data will still be saved. They are only deleted after a long period of inactivity (login + subscription), not simply for pausing payment. You will still receive an email notification before any cancellation.
So you can safely pay only for the season you use and reactivate the next year without losing your data.

thank you very much, I’ll do as you say even if it doesn’t seem right to me to pay only for 4 months… 10 euros for the season would be fair…
