Billing
Billing and refunds.
Last updated 15 November 2026
The short version: try Pro free for 14 days, cancel any time, and keep what you paid for until the period ends. Here is exactly how billing works.
What you are buying
Pro is a subscription to extra features in Calcifir, delivered online. Nothing is shipped. Pro switches on in your account as soon as your trial starts or your payment goes through, and stays on until your subscription ends.
Pro costs $12 a month, or $120 a year paid up front. Prices are in US dollars. What each plan includes is on the pricing page.
The free trial
- Pro starts with a 14-day free trial. You add a card when you start it, and you aren’t charged during the trial.
- If you don’t cancel, the trial turns into a paid subscription when it ends, and your card is charged for the monthly or yearly plan you picked.
- If you cancel during the trial, you pay nothing and keep Pro until the trial ends.
- The trial is offered once per account.
Billing and renewal
- Payments are taken by Stripe. You enter your card on Stripe’s own page, and Calcifir never sees or stores the card number.
- Your subscription renews automatically at the end of each month or year, on the same date you started paying, until you cancel. Stripe emails a receipt for each payment.
- You can change your card or see past invoices on Stripe’s billing page, which also opens from Manage subscription in Settings › Account.
Cancelling
You can cancel at any time, in a few clicks: open Manage subscription in Settings › Account, or go to Stripe’s billing page. You don’t need to email us or give a reason.
When you cancel, you keep Pro until the end of the period you already paid for, and you aren’t charged again. Then your account moves to Free. Your plans stay exactly as they are; nothing is deleted, and the Pro-only features lock until you subscribe again.
Refunds
Because you can cancel at any time and keep Pro to the end of the period, we don’t refund part of a month or year, except where the law requires it.
We will always refund a charge that was our mistake or Stripe’s, such as:
- being charged twice for the same period;
- being charged after you cancelled;
- being charged for a trial you cancelled in time.
Email hello@calcifir.com from the address on your account and tell us which charge. A refund goes back to the card you paid with; your bank may take several days to show it.
Deleting your account
Deleting your account ends your subscription straight away, along with the rest of the period you paid for, and that remainder isn’t refunded. If you want to use the time you paid for, cancel first and delete your account when the period ends.
If a payment fails
If your card is declined at renewal, Stripe tries it again over the following days and you keep Pro while it does. Update your card on Stripe’s billing page to settle it. If the payment still can’t be collected, the subscription ends and your account moves to Free, with your plans kept.
Price changes
If we change the price of Pro, we will tell you by email before the new price applies to you. It starts at your next renewal, so you can cancel before then if you don’t want to pay it.
