Privacy Policy

CycleQuest ("CycleQuest," "we," "our," or "us") respects your privacy. This Privacy Policy explains how we collect, use, store, sync, and share information when you use the CycleQuest mobile application and related services (the "Services"). Section 2 lists, line-by-line, what we store on your device, what we sync to our backend when you sign in, and what we never collect.

1. Scope

This Privacy Policy applies to information collected through the CycleQuest mobile app, related backend APIs, and any partner-linking features that connect CycleQuest to companion services such as CalmHer.

CycleQuest is local-first wherever possible. Some features — premium subscription and partner-linking with CalmHer — require a CycleQuest account, and using those features causes a defined set of data to be synced to our backend. The complete inventory is in Section 2 below.

2. Information We Collect

A. Information You Provide Directly

Depending on how you use CycleQuest, we may collect information you enter into the app, including:

B. Information Stored Only on Your Device

The following data is stored only on your device using the device's local storage. It is never sent to our servers under any circumstances:

If you use the app without creating an account, everything you enter stays on your device and never reaches our servers.

C. Apple HealthKit and Android Health Connect Data

If you grant CycleQuest permission to read from Apple HealthKit (iOS) or Android Health Connect, the app may read data such as sleep, heart rate variability, resting heart rate, basal body temperature, and active energy in order to provide personalized insights inside the app. CycleQuest does not currently write any data back to Health.

HealthKit and Health Connect data is processed entirely on your device. CycleQuest never transmits raw HealthKit or Health Connect data to our servers, to CalmHer, or to any third party. You may revoke this permission at any time from your device's settings (iOS: Settings → Privacy & Security → Health → CycleQuest; Android: Health Connect app). See the Health Data page for the full per-data-type list.

D. Information Synced to Our Backend (Account Holders Only)

If you create a CycleQuest account, the following information is synced from your device to our backend so that account features, premium subscription, and partner-linking can function. This is the complete list — we do not sync anything else:

Account and authentication

Cycle profile

Daily check-ins (every check-in you log)

Past cycles

Custom symptoms — symptom names and categories you create.

Gamification

Subscription and billing status

We do not store credit card numbers, bank details, or full payment information. Payment processing is handled directly by the relevant payment provider (Apple, Google, or Stripe), and we receive only the resulting subscription status.

Partner linking (only if you use this feature)

If you do not create an account, none of the data above is sent to our backend and CycleQuest functions entirely on your device. Premium and partner-linking features are unavailable without an account.

E. Automatically Collected Technical Information

When you interact with our backend (account features, premium subscription, or partner-linking), we may automatically collect limited technical information needed to operate, secure, and improve the Services, such as:

We do not use third-party analytics, advertising, or tracking SDKs. CycleQuest does not include Google Analytics, Firebase Analytics, the Facebook SDK, Mixpanel, Amplitude, PostHog, Sentry, or any similar tools. We do not track you across other apps or websites.

3. How We Use Information

We use information we collect to:

We do not use your information for advertising, profiling, or to build behavioral profiles of you, and we do not sell your information.

4. Partner Linking and Sharing with CalmHer

CycleQuest can connect to a companion app called CalmHer, which allows a partner you choose to receive supportive insights based on your cycle.

If you choose to connect CycleQuest with CalmHer:

Note that the underlying data described in Section 2(D) is stored on our backend so that summaries can be computed — but only the limited summary above is ever returned to CalmHer, and only when you have linked your accounts and only for the fields you have consented to share.

5. Local Storage and Backend Sync

CycleQuest uses a combination of local device storage and (for account holders) backend sync.

6. Data Sharing

We do not sell your personal information. We do not share your information with advertisers or data brokers.

We share information only in the following limited circumstances:

7. Data Retention

We retain information for as long as reasonably necessary to:

You can delete your account at any time from inside the app. When you delete your account, we permanently delete: your account record, profile, all synced check-ins, past cycles, custom symptoms, gamification stats and badges, partner-link state and consent settings, and active session tokens. Data stored only on your device (journals, intimacy log, recipe favorites, grocery list, HealthKit / Health Connect data, etc.) is removed when you delete the app or clear app storage on your device.

Backups maintained by our infrastructure provider may retain deleted data for a short rolling window (typically up to 30 days) before being permanently expunged.

8. Your Choices and Rights

Depending on the functionality available to you, you may be able to:

If you are located in the European Union, the United Kingdom, California, or another jurisdiction with data subject rights (such as access, correction, deletion, portability, or objection), you may exercise those rights by contacting us at the email below.

9. Data Security

We use reasonable administrative, technical, and organizational safeguards to protect information we process, including:

However, no system is completely secure, and we cannot guarantee absolute security. Because much of your sensitive data lives on your device, we strongly recommend you also protect your device with a passcode, Face ID, or Touch ID.

10. Children's Privacy

CycleQuest is not intended for children under 17, and we do not knowingly collect personal information from children under 17 through the Services. If we learn that we have inadvertently collected personal information from a child under 17, we will delete that information.

11. Wellness / Medical Disclaimer

CycleQuest is a wellness and informational tool only. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Cycle predictions and insights are estimates based on the information you provide and should not be relied upon as a method of contraception or for diagnosing any medical condition. You should not rely on CycleQuest as a substitute for professional medical advice. Always consult a qualified health professional for medical concerns.

12. International Use

If you use the Services from outside the United States, you understand that your information may be processed in the United States or in other jurisdictions where our service providers operate, subject to applicable law.

13. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. If we do, we will update the Effective Date above and post the revised version in the app and at this URL. Material changes will be communicated through an in-app notice when reasonable. Your continued use of the Services after changes become effective constitutes acceptance of the updated Privacy Policy.
