CIRA.
Terms of Use
Last updated: August 27, 2026
Cira is licensed, not sold, under Apple's
Standard
End User License Agreement. That agreement governs your use of the app. The
notes below explain the parts people actually ask about.
Subscriptions
Cira Premium is offered as a weekly or a monthly auto-renewing subscription, or
as a one-time Lifetime purchase. Prices are shown in your local currency on the
plans screen before you buy.
Auto-renewing subscriptions renew at the end of each period unless auto-renewal
is turned off at least 24 hours before the period ends. Your Apple Account is
charged for the renewal within 24 hours of the end of the current period.
Free trial
The weekly plan may include a three-day free trial. If you subscribe during a
trial, the trial ends and the paid period begins. Any unused part of a free trial
is forfeited when a subscription is purchased.
Managing and cancelling
Subscriptions are managed by Apple. Open iOS Settings → your name →
Subscriptions to change the plan or turn off renewal. Cancelling stops future
charges; access continues until the end of the period you have already paid for.
We cannot cancel a subscription on your behalf.
Lifetime
Lifetime is a one-time, non-consumable purchase. It does not renew and cannot
be cancelled, because there is nothing to cancel. It stays with the Apple Account
that bought it and can be restored on any device signed in to that account.
Refunds
All payments are handled by Apple, so refunds are handled by Apple too:
reportaproblem.apple.com. We have no
ability to issue or decline a refund.
What Cira is free to do
Logging drinks, the active caffeine figure, tonight's verdict, your last safe
cup, today's curve, and metabolism speed with your sleep times are free and stay
free. Premium adds the before-you-drink check, the fine physiology model, the
focus window, history beyond a week, your own drinks, the cutoff reminder and the
full statistics.
What Cira is not
Cira is not a medical device and does not give medical advice.
It estimates caffeine levels using a standard one-compartment pharmacokinetic
model with first-order absorption. That is a good approximation of a typical body,
but it is not a measurement of yours, and individual variation is large. Do not
use Cira to make medical decisions. If you have a sleep disorder, a heart
condition, are pregnant, or take medication that interacts with caffeine, talk to
a doctor.
Availability
The app is provided as is. We may change or discontinue features in future
versions.
