Luna is the period tracker that actually respects your privacy. With 99% accurate predictions powered by on-device AI, your intimate health data never leaves your phone. No cloud, no sharing, no ads. Track periods, ovulation & symptoms with complete privacy.
Is there an Android version?
@joana_pessoa Hi Joana! Yes, Android version is coming in January 2025! 🚀
We're taking extra time to ensure the same privacy standards using Android's Private Compute Core.
Thanks for your interest! 💜
How do you make money if you don't collect data?
@guilherme_mamare Great question Guilherme! We use a simple, honest subscription model:
- Free: Basic tracking, predictions & calendar
- Premium: $4.99/mo or $29.99/year - advanced analytics, extended predictions, PDF exports
- Lifetime: $99 one-time purchase
No ads, no data selling, just software you pay for. We believe privacy shouldn't be a luxury feature!
The old model of "free app = selling your data" needs to end, especially for health apps 🔒
Can you sync between devices?
@agendoor Yes! But privacy-first 🔒
Two options:
1. iCloud Sync: End-to-end encrypted using your iCloud Keychain
2. Local WiFi Sync: Direct device-to-device, no internet needed
Both methods mean we NEVER see your data - the encryption keys stay with you. Think Signal-level encryption but for period tracking!
Your data, your control 💜
What happens if I lose my phone?
@pedro_santos30 Hi Pedro! (great name btw 😄)
If you enabled encrypted backup:
- iCloud backup restores everything automatically
- Only YOU have the encryption keys - we can't access even if we wanted
If you didn't enable backup:
- Data is lost (that's the trade-off for true privacy)
- But Luna learns your patterns quickly when you start fresh!
We recommend enabling encrypted backup for peace of mind - best of both worlds! 🙂
