Body intelligence, not just tracking
Red Diary
Your cycle. Your data. Your device.
Red Diary is a cycle tracking and body intelligence app that tells you what to do today — not just what day you're on. No account. No cloud. No analytics. Everything stays on your iPhone.
Body intelligence
Every screen answers "what should I do today" — not just "what day is it."
Privacy first
No account. No cloud. No analytics. Your data never leaves your device.
Four modes
Cycle tracking, pregnancy, trying to conceive, and avoiding pregnancy — each with its own intelligence.
Your privacy is non-negotiable
Red Diary was designed from day one with a simple rule: your reproductive health data belongs to you and no one else.
No account required
Open the app and start. No email, no sign-up.
No cloud sync
All data stored locally on your iPhone via encrypted storage.
No analytics
Zero tracking. No ad SDKs. No third-party data sharing.
HealthKit read-only
We read steps, sleep, and activity. We never write to or share your Health data.
