Ruyue is a private space for two people. Not a feed, not a social network, and not another place to perform a relationship — just a quiet app where the parts of a shared life that usually scatter across chats, notes, and calendars finally sit together.
A Different Kind of Closeness
- Understand Before Guessing: cycle phases, energy, and mood give context to a hard day instead of leaving it unexplained.
- Say Things at the Right Moment: seal a letter today and let it arrive when it matters most.
- Keep the Small Stuff Shared: lists, dates, expenses, and plans stop living in one person’s head.
- Stay Close Without Surveillance: location and presence are opt-in, time-limited, and always visible while active.
Privacy as the Design
Ruyue treats intimacy as something that only works when it is safe. Vault contents and letters are encrypted on the device, location sharing has no history, and every signal your partner can see is one you chose to share. Nothing is inferred about your relationship and nothing is scored against it.
Two people. One quiet space. Everything else stays outside.
Everything you need
Everything you need to know about this app
Cycle & Mood Awareness
See cycle phases, energy, symptoms and mood at a glance. Ruyue offers context, not a verdict, so care can start with understanding.
Timed Letters
Write, seal and deliver a letter now or on a future date. End-to-end encryption keeps what is inside between the two of you.
Snaps & Walkie-Talkie
Send a view-once photo or a short voice note that disappears after it is heard. Immediate, intimate and never added to an album.
Shared Everyday Life
Share lists, special dates, expenses and wardrobe notes so the small mental load of life lives in one calm place that belongs to both of you.
Live Location, On Your Terms
Start a time-limited live location session with a clear, persistent indicator. There is no location history, and sharing can be stopped at any time.
Battery & Presence
Opt in to show your current battery level and send one thoughtful nudge when your partner is running low. Stale readings are dated instead of pretending to be live.
Private Vault
Keep cards, passwords, addresses and notes in an encrypted vault. Encryption happens on your device, and the server never receives the key that could read them.
Compatibility & Ruyue AI
Explore love languages, personality prompts, daily compatibility and a relationship assistant built as a conversation starter, never a judgment.
