What happens after the 10 days
No surprises. Here is exactly what each outcome looks like.
If you do nothing
On day 11 your card is charged $2.99 and Serious Reefer continues monthly. We email you 3 days beforehand with the date and the amount, so the charge is never a surprise. Cancel any time after that too.
If you cancel during the trial
You are never charged. There is no partial month or cancellation fee. You keep full Serious Reefer access until the last day of the trial, then move to the free Starter plan.
On the free Starter plan
Your tanks, readings and photos stay exactly as they are. Nothing is deleted. You can keep logging water parameters on 1 aquarium with up to 4 livestock. Advanced charts, reports and the AI features pause until you subscribe, and your monthly AI credits stop.
Subscribe again whenever you like and everything unlocks exactly where you left it. Cancel from Dashboard → Subscription at any point, in two clicks.
