Lumina ("we," "our," or "the app") is a period and cycle tracking application for iOS. This policy explains what data the app handles, where it lives, and the choices you have. The short version: your cycle data is stored on your device and we do not collect it.
1. Data stored on your device
Everything you log in Lumina — period flow, symptoms, mood, energy, sleep, stress, basal body temperature, LH and pregnancy test results, cervical mucus observations, intimacy logs, notes, and journal entries — is stored locally on your iPhone using Apple's on-device database. Your settings (cycle length, life-stage mode, reminder preferences) are also stored locally.
We do not operate servers that receive, store, or process your cycle data. We cannot see it, sell it, share it, or hand it over — because we never have it.
2. No account required
Lumina does not ask you to create an account and does not collect your name, email address, phone number, or precise location. There is no sign-up.
3. Apple Health (HealthKit)
If you choose to enable it, Lumina can write your menstrual flow data to Apple Health. This is optional and off by default. Data shared with Apple Health is governed by Apple's privacy practices and your iOS Health permissions, which you can revoke at any time in Settings. Lumina does not use HealthKit data for advertising or share it with third parties, as required by Apple's guidelines.
4. Purchases
Premium subscriptions are processed entirely by Apple through the App Store. We receive anonymized transaction receipts to unlock premium features; we do not receive your payment details, billing address, or identity.
5. No ads, no tracking
- Lumina contains no advertising and no third-party ad SDKs.
- We do not use third-party analytics or tracking SDKs.
- We do not sell or share personal information, including under the California Consumer Privacy Act (CCPA/CPRA) definitions of "sell" and "share."
6. Reproductive health data
We recognize that menstrual and reproductive health data deserves the highest level of protection. Because your data is stored only on your device, Lumina has no ability to produce it in response to third-party requests, including legal requests. Anyone seeking your data would have to seek it from you, on your device, under the protections your device provides.
7. Device backups
Your iPhone backups (iCloud Backup or local backups) may include Lumina's data as part of Apple's standard device backup. These backups are controlled by you and governed by Apple's security practices, including end-to-end encryption when Advanced Data Protection is enabled.
8. Data deletion
You can permanently erase all Lumina data at any time using Profile → Delete All My Data inside the app, or by deleting the app from your device. Because we hold no copy, deletion on your device is deletion everywhere.
9. Children
Lumina is not directed at children under 13, and we do not knowingly collect personal information from children under 13.
10. Changes to this policy
If we change this policy, we will update the effective date above and note material changes in the app's release notes. Continued use of the app after a change means you accept the updated policy.
