Privacy Policy

Last updated July 13, 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.

Partner view (only if you turn it on)

Partner view lets you share a live, read-only dashboard with one person you invite. If you turn it on:

• Your iPhone publishes a small summary — today's phase in plain language, the day of your cycle, and upcoming dates such as when your fertile window is expected to open. Your raw logs (temperatures, mucus observations, symptoms, intimacy, notes) are never included.
• The summary travels through your own iCloud account using Apple's CloudKit sharing. NaturalBloom operates no server and cannot read it — the data moves between your iCloud, Apple, and the one person you invited.
• Sharing is invite-only and limited to exactly one participant, and it is read-only — your partner can never edit anything.
• You can revoke access at any time from Settings → Partner view; your partner's dashboard goes blank immediately.
• If you enable Discreet mode, the day-level details are removed from the summary before it leaves your phone.

Partner view is off by default. If you never turn it on, nothing is ever published.

Purchases

NaturalBloom is free for your first 14 days, after which it is 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.
