Terms of Service
Last updated: October 6, 2026
These Terms of Service ("Terms") are an agreement between you and the developer of Period Productivity ("Period", "the App", "we", "us"). Please read them carefully — especially Section 3 (Medical Disclaimer) and Section 10 (Limitation of Liability).
1. Acceptance
By creating an account or using the App you agree to these Terms and to our Privacy Policy. If you do not agree, do not use the App.
2. Eligibility
You must be at least 18 years old to use the App. By using it, you confirm that you are.
3. Medical Disclaimer — the App and its AI are not a doctor
- Information only. All content in the App — cycle and phase predictions, hormone curves, energy levels, the descriptions on each screen, and every AI-generated summary or suggestion — is provided for general informational, educational and personal-reflection purposes only. It is not, and must not be treated as, medical advice, diagnosis, treatment or a prescription.
- Not a medical device. The App has not been evaluated or cleared by the U.S. Food and Drug Administration, the European Medicines Agency or any other regulator, and is not intended to diagnose, treat, cure, monitor or prevent any disease or condition.
- AI can be wrong. AI Summary is written automatically by a third-party language model from the entries you choose. It can be inaccurate, incomplete or out of context, and it has no knowledge of your medical history. It is not a substitute for professional medical advice.
- Never delay care. Always seek the advice of a physician or other qualified healthcare provider with any question about a medical condition, symptoms, pain, fertility, pregnancy or contraception. Never disregard professional medical advice, or delay seeking it, because of something you read in the App.
- Not for contraception or conception. Predictions are estimates based on averages and on what you enter, and may be wrong — especially for irregular cycles. Do not use the App as a method of contraception or to plan or avoid pregnancy.
- Emergencies. If you think you may have a medical emergency, contact your local emergency services immediately.
- Your decisions. You are solely responsible for any decision you make based on content in the App. To the fullest extent permitted by law, we are not liable for any loss or harm arising from reliance on that content, including any delay in seeking medical care.
4. Your Account
You are responsible for the accuracy of what you enter and for the security of the Apple or Google account you sign in with. Tell us promptly if you believe your account has been accessed without your permission.
5. Free Features and Premium
Tracking, the calendar, predictions and the hormone view are free. Period Premium is an optional, paid, auto-renewing subscription that unlocks AI Summary.
- Plans. Premium is offered monthly or yearly. The price, in your local currency and including any applicable taxes, is shown on the purchase screen before you confirm.
- Billing. Payment is charged to your Apple ID at confirmation of purchase. All payments are processed by Apple; we never receive or store your card or bank details.
- Auto-renewal. Your subscription renews automatically at the same price for the same period unless you turn off auto-renew at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the end of the current period.
- Cancelling. You can manage or cancel your subscription at any time in your device's Settings › Apple ID › Subscriptions. Cancelling stops future renewals; you keep Premium until the end of the period you have paid for.
- Refunds. Refunds are handled by Apple under Apple's refund policies (reportaproblem.apple.com). We cannot issue refunds directly. Nothing in these Terms limits any statutory right you have to a refund or withdrawal.
- Price changes. If the price changes, Apple will notify you in advance and, where required, ask you to agree before you are charged the new price.
- Fair use. To keep the service reliable, AI Summary is limited to one new summary per account per day. We may adjust features of Premium over time; if we materially reduce what Premium includes, we will tell you in advance so you can cancel.
6. AI Features and Your Consent
AI Summary works only after you give separate, explicit consent to the processing of your health data for that purpose (see Privacy Policy, Section 6). You can withdraw consent at any time by turning on Privacy Mode; AI Summary then stops working, so you may also want to cancel your subscription with Apple. Withdrawing consent does not affect processing that happened before you withdrew it.
7. Acceptable Use
You agree not to: reverse engineer, decompile or attempt to extract the source code of the App except where the law allows it; scrape, overload or interfere with our servers; access or try to access anyone else's data; resell or share access; use the AI features to generate content unrelated to your own log; or use the App for any unlawful purpose.
8. Intellectual Property
The App, its design, illustrations and content belong to us or our licensors. We grant you a personal, non-transferable, non-exclusive, revocable licence to use the App on Apple devices you own or control, under these Terms and Apple's Licensed Application End User License Agreement. Your entries remain yours.
9. Disclaimer of Warranties
The App is provided "as is" and "as available". To the fullest extent permitted by law, we disclaim all warranties, express or implied, including fitness for a particular purpose, accuracy and non-infringement. We do not guarantee that predictions or AI content will be accurate, or that the App will be uninterrupted or error-free.
10. Limitation of Liability
To the fullest extent permitted by law, we are not liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, health outcomes, profits or goodwill, arising from your use of or inability to use the App. Our total liability for any claim relating to the App is limited to the amount you paid us for Premium in the 12 months before the claim. Nothing in these Terms excludes or limits liability that cannot be excluded or limited by law, including liability for death or personal injury caused by negligence, for fraud, or your rights as a consumer under mandatory law.
11. Ending Your Use
You can stop using the App and delete your account at any time from Profile › Delete Account. Deleting the App or your account does not cancel a subscription — cancel it with Apple. We may suspend or end access for anyone who breaches these Terms.
12. Changes
We may update these Terms. We will change the date above and, for material changes, tell you in the App before they take effect. If you continue to use the App after that, the updated Terms apply. If you do not agree, stop using the App and cancel any subscription.
13. Governing Law
Period Productivity is made by an independent individual developer, not a company. These Terms are governed by the laws of the country where the developer is habitually resident, without regard to its conflict-of-law rules. If you are a consumer, you also keep the protection of the mandatory laws of your country of residence, and you may bring claims in the courts there.
14. Apple
These Terms are between you and us, not Apple. Apple is not responsible for the App or its content, has no obligation to provide maintenance or support, and is not responsible for any product-liability, legal-compliance or intellectual-property claim relating to the App. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
