Terms of Use
The short version. Calla is a tracker, not a doctor. Your entries are yours and stay on your phone. Subscriptions are billed by Apple and cancelled in your Apple account, and cancelling never takes your data away.
1. These terms
Calla is provided by [LEGAL NAME, COUNTRY – fill in before publishing] ("we", "us"). By installing or using the app you accept these terms. If you do not accept them, delete the app – there is no account to close.
2. What Calla is, and what it is not
Calla helps you record symptoms, cycles and treatment, and turn that record into a report for an appointment. It shows patterns in the entries you made, always alongside how many days those patterns rest on.
Calla is not a medical device, and nothing in it is medical advice, a diagnosis, or a recommendation about treatment or dosage. It cannot detect a condition, and a quiet chart is not reassurance. Decisions about your health, medication and hormone therapy belong with a qualified clinician who knows your history.
Never delay seeking medical care because of something you saw in the app. If you think you are having a medical emergency, contact your local emergency number.
3. Your licence
We grant you a personal, non-transferable, non-exclusive licence to use Calla on Apple devices you own or control, in line with Apple's usage rules. Where these terms are silent, Apple's standard End User Licence Agreement applies. You may not copy, resell, reverse engineer or redistribute the app except where that restriction is prohibited by law.
Apple is not a party to these terms and has no obligation to provide support for the app. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.
4. Subscriptions, trials and billing
- Calla Pro is an auto-renewing subscription. The price, the billing period and the date of the first charge are shown in the app before you confirm anything.
- Payment is charged to your Apple ID account when you confirm the purchase. Apple, not us, processes every payment.
- The subscription renews automatically unless you cancel at least 24 hours before the current period ends. Apple charges the renewal within the 24 hours before that date.
- Manage or cancel at any time in iPhone Settings → your name → Subscriptions. Deleting the app does not cancel a subscription.
- Where a free trial is offered, its length is shown before it starts. Any unused part of a trial is forfeited when you buy a subscription.
- Refunds are handled by Apple under its own policy. We cannot issue refunds for purchases Apple processed, but write to us and we will help you ask.
- If prices change, the change applies from the next billing period, and Apple will ask you to agree before renewing at a new price.
Exporting your data and generating the doctor report are never blocked by a subscription, a trial that ended, or a payment that failed.
5. Your data is your responsibility
Because your entries live on your device and we hold no copy, we cannot recover them for you. If you lose the phone, reset it, or delete the app without a backup, the entries are gone. Turning on iCloud backup, or exporting from time to time, is the way to protect against that – see Support.
6. Acceptable use
Use Calla for your own health record. Do not use it to break the law, to interfere with the app's operation or security, or to present its output as a clinical assessment of anyone.
7. Changes and availability
We improve the app over time, and features may change or be removed. If a change materially reduces what a paid subscription gives you, we will say so before it takes effect. We do not promise uninterrupted availability, and we may discontinue the app; if that happens we will give notice in the app so you can export your data first.
If we change these terms, the date at the top changes. Continuing to use the app after that means you accept the new version.
8. Disclaimers and liability
The app is provided "as is" and "as available", without warranties of any kind to the extent the law allows, including any warranty that it is accurate, uninterrupted or fit for a particular purpose.
To the extent permitted by law, our total liability arising from the app is limited to the amount you paid us for it in the twelve months before the claim. Nothing here limits liability for death or personal injury caused by negligence, for fraud, or for anything else that cannot lawfully be limited. If you are a consumer, your statutory rights are unaffected by these terms.
9. Governing law
These terms are governed by the laws of [JURISDICTION – fill in before publishing], without regard to conflict of law rules. If you are a consumer resident elsewhere, you keep the protection of the mandatory law of your country of residence and may bring proceedings there.
