Email info@finoha.net from the address on your account and we will send you a secure Stripe link to update the card.
Never send card details by email. We will not ask for them, we cannot accept them that way, and you should not send them to anyone who does ask.
Updating the card yourself inside the app is on the way. Until it ships, the secure link is how it is done — it takes us a business day at most.
If your card is expiring: you often do not need to do anything. Stripe's card-updater service refreshes expiry dates automatically for most major card networks.
If a renewal has already failed, update the card as soon as you can. We retry failed payments over several days before suspending access, so an update within that window usually keeps your subscription running without a gap.
