YumeOS is a private, hand-made yumeshipping app for people who love fictional others (F/Os): yumeshippers, self-shippers, self-insert and x reader fans, OC lovers, otome fans and anyone whose comfort character, husbando or waifu feels like part of their life.

Your yumeship in one place: F/O profiles and ship sheets, days together, a yume journal, a shrine for your F/O, pretend chats and calls, and a cozy life sim where you live with your F/O.

Everything you make stays on your phone. You don't need an account, and YumeOS has no analytics of its own.

What you can do
• F/O profiles: personality, likes, gift ideas, lore, a ship sheet, a relationship map and a character you design yourself in the Character Creator (body types, hair, outfits and more)
• A self-insert journal with stickers, plus memories, a timeline, AUs, your merch collection, commissions and the artists you love
• Polyships: you and two or more F/Os as one ship (with PRO)
• Studio: fill-in templates, a design editor, F/O shrines and phone wallpapers, saved as images
• Pretend chats and calls with your F/O, chat wallpapers and little companion messages
• Home-screen widgets with PRO: days together, today's message and your next call
• Check-ins, a study timer, Home styles, and backups you keep yourself

Yume Life
A cozy life simulator where you live with your F/O: decorate your rooms with hundreds of hand-drawn furniture pieces, dress up, visit places, cook, go on dates and play mini-games. Earn Yume Coins by playing, collect a little gift every day and win Yume Diamonds from challenges. No loot boxes and no timers that punish you; coins and diamonds are earned by playing, never sold. Activities, places and rooms are the same on every plan.

Yume Garden (optional, 13+)
A kind, moderated yumeshipping community where you can share your F/Os, fan art, writing, designs and shrines with other yumeshippers. Follow people, leave kind notes, chat, join group chats and decorate your profile with blinkies and profile designs. Only what you choose to post is uploaded. Sign in with Google to join. Report, block and mute are on everything, and you can download your data or delete your account inside the app.

Hand-made, no AI
Every illustration (characters, furniture, rooms, stickers, templates) is original art made for the app. No AI features and no copyrighted characters: you bring your own F/Os.

Plans
YumeOS is free to use: all of Yume Life, the journal, memories, timeline, chats, Studio and Yume Garden, with 3 F/Os, 40 templates, 4 Home styles and 51 stickers.

YumeOS PRO (optional, monthly or yearly): every template, Home style and sticker, room for 15 F/Os with 300 photos each, a bigger collection, more AUs and shrines, planned and repeating calls, phone widgets, polyships, PRO decorations and outfits in Yume Life, and fewer ads: small banners only, never full-screen.

YumeOS Premium (monthly or yearly, or once for good with Lifetime): everything in PRO without limits, PDF export, Yume Garden profile designs, every Yume Life item except the video items, and no ads, except the optional reward videos in Yume Life, which play only when you tap one.

Prices are shown before you buy. Subscriptions renew until you cancel them in Google Play. If a plan ends, nothing you made is deleted: Yume Life items you placed stay in your rooms, and items you collected with coins, diamonds or videos are yours to keep.

Ads come from Google AdMob: never inside a chat or a call, while you are making something, or over your Yume Life room.

Privacy
Your F/Os, journal, photos and designs never leave your device unless you post them in Yume Garden. Without Premium (and on Premium only once you tap a Yume Life reward video), Google AdMob receives your advertising ID, approximate location and how you interact with ads (where the law requires it, you are asked first). RevenueCat keeps your purchase history under a random ID. The full privacy policy is linked on this page.
