Frequently Asked Questions
Everything you need to know about LunaCycle — privacy, features, and how it compares to other period trackers.
What is LunaCycle?
LunaCycle is a privacy-first period, fertility, and perimenopause tracker that never sells your data. Track cycles with Anonymous Mode — no account required — and on-device AES encryption.
Is LunaCycle free?
Yes, LunaCycle is free to start. Anonymous Mode with period tracking, cycle predictions, and daily logging is completely free. LunaCycle Plus unlocks AI insights, wearable sync, and advanced analytics for $4.99/month or $34.99/year.
Does LunaCycle sell my data?
Never. LunaCycle does not sell, share, or broker your data. All entries in Anonymous Mode stay encrypted on your device. We are the privacy-first alternative to Flo, Clue, and other trackers that monetize your health data.
Can I use LunaCycle without an account?
Yes. Anonymous Mode lets you track your period, log symptoms, and view cycle predictions with zero account required. Your entries stay encrypted on your device only.
How does LunaCycle compare to Flo?
LunaCycle is the privacy-focused alternative to Flo. While Flo has faced criticism for sharing user data with third parties, LunaCycle never sells or shares your data. LunaCycle also offers Anonymous Mode (no account needed), on-device encryption, and AI-powered cycle insights — features Flo doesn't offer.
How does LunaCycle compare to Clue?
LunaCycle offers the same cycle tracking accuracy as Clue but with stronger privacy protections. LunaCycle includes Anonymous Mode, on-device AES encryption, and a perimenopause tracking mode. Clue requires an account and stores data in the cloud.
Does LunaCycle track fertility and ovulation?
Yes. LunaCycle includes fertility window predictions and ovulation tracking, available with LunaCycle Plus.
Can LunaCycle track perimenopause?
Yes. LunaCycle has a dedicated perimenopause mode that tracks irregular cycles, symptoms, sleep quality, and mood changes during the menopause transition.
Does LunaCycle support wearable integration?
LunaCycle Plus syncs with popular wearables to automatically log basal body temperature and activity data for more accurate cycle predictions.
Is LunaCycle available on Android and iOS?
LunaCycle is a progressive web app (PWA) that works on any device — Android, iOS, or desktop. Install it directly from your browser or look for it on Google Play.
