Privacy Policy
Last updated April 29, 2026
NaturalBloom is a fertility-awareness app built around the principle that your body data
belongs to you. This policy explains what we collect, what we don't, and how to reach us.
Short version
- Everything you log — temperatures, mucus observations, period flow, intimacy, notes —
is stored locally on your device.
- We don't run servers that hold your cycle data. We don't sell, share, or analyze it.
- We don't track you with advertising IDs and we don't ship third-party advertising or
analytics SDKs.
Data we store on your device
- Daily logs (temperature, cervical mucus, period flow, LH test result, intimacy,
free-text notes).
- App settings (your goal, preferred temperature unit, average cycle length, reminder
preferences).
- Imported history if you choose to import from another tracker.
This data is held in your device's secure local storage. It never leaves your device
unless you initiate an export, share, or sync.
Data we receive from third parties (only if you opt in)
- Apple Health: If you turn on Apple Health sync in
Settings, NaturalBloom reads cycle, temperature, and related metrics you've granted access
to, and writes the same back. Sync happens on your device. We do not see this data.
- Bluetooth thermometers: Pairing with a thermometer such as Tempdrop
happens directly between your device and the thermometer. We don't receive readings.
Purchases
NaturalBloom is sold as a one-time purchase. Purchase verification is processed through
RevenueCat, our purchase infrastructure provider. RevenueCat receives an anonymous user ID
and whether you have purchased NaturalBloom. It does not receive your cycle data,
name, or email. Billing itself is handled by Apple (App Store) or Google (Play Store).
RevenueCat's privacy policy is available at
revenuecat.com/privacy.
Diagnostics
If the app crashes, your device may share an anonymous crash report with Apple or Google
under your operating-system settings. NaturalBloom does not receive these reports directly.
Your choices
- Export your data at any time from Settings → Your history.
- Delete your data by tapping Reset all data in Settings, or by
uninstalling the app.
- Revoke health sync from your device's Apple Health
privacy settings.
Children
NaturalBloom is intended for adults of reproductive age. We do not knowingly collect data
from children under 13.
Changes to this policy
If we change anything material, we will update the date at the top of this page and
surface a notice in the app on next launch.
