About Ruyue: Couples & Cycle
Ruyue is a private space for two.
Most friction in a relationship is timing, not feeling. Ruyue puts the context in front of both of you — where she is in her cycle, how they slept, the mood they logged, what the moon is doing — so you stop guessing and start noticing.
SEALED LETTERS
Write your partner a letter and seal it. They open it themselves, once. Letters are end-to-end encrypted, stored only as ciphertext we cannot read, and a letter disappears when it is put down. Schedule one for a date in the future and let it arrive on the day that matters.
CYCLE, TOGETHER
Map your cycle once and Ruyue tracks the phase for both of you. Your partner sees the phase and what tends to help — never your raw data unless you share it. Timeline, predictions, and honest notes for the days that are harder. Not medical advice, and not a contraceptive method.
MOOD AND PRESENCE
Log how you feel in a tap. See each other's day at a glance. Share your live location while you want it on, off the second you don't — no history is kept.
SNAP AND WALKIE-TALKIE
Send a one-time photo or a short voice message. Both are deleted once opened or heard. No feed, no archive, no audience.
KNOW YOURSELF
Take established personality assessments — the IPIP-50 five-factor model, the Rorschach inkblots, and lighter ones for fun. Results are yours; share them with your partner if you want to. For reflection, not diagnosis.
ASTROLOGY AND COMPATIBILITY
Daily horoscope, moon phase, and a synastry-based harmony reading between the two of you. For conversation, not prediction.
THE PRACTICAL STUFF
Shared lists you both edit at once. Special days counted down. A joint income and spending ledger. A locked vault for photos only the two of you see. Wardrobe, mini games, and home-screen widgets to poke each other.
PRIVACY BY DEFAULT
Letters and vault items are end-to-end encrypted. App lock with Face ID or fingerprint. Location is never stored as history. You choose what your partner sees, always. Remove your partner at any time and everything shared between you is deleted for both of you.
RUYUE PREMIUM
Premium removes the limits: more letters at once, scheduled future letters, take a letter back before it is opened, and the advanced AI assistant. Subscription auto-renews unless cancelled at least 24 hours before the period ends. Manage it in Google Play.
IMPORTANT HEALTH NOTICE
Ruyue is not a medical device and does not provide medical advice, diagnosis or treatment. Cycle phases and dates are estimates calculated from the information you enter; they are not a contraceptive method and must not be used to plan or avoid pregnancy. The personality assessments are for self-reflection and are not a psychological diagnosis. Always consult a qualified healthcare professional for medical advice, diagnosis or treatment, and for any symptom that concerns you. Never disregard professional medical advice or delay seeking it because of something you read in this app. If you think you may have a medical emergency, contact your doctor or your local emergency number immediately.
Ruyue is for two people who chose each other. There is no feed, no discovery, and no way to reach anyone but your one partner.
