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 and anyone whose favourite character feels like part of their life.

Your yumeship in one place: F/O profiles and ship sheets, days together, a yume shipping journal and a cozy life sim 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
• A journal with stickers, plus memories, a timeline, AUs, your merch collection, commissions and the artists you love
• Studio: fill-in templates, a design editor, shrines and phone wallpapers, saved as PNG or JPG
• Pretend chats and calls with your F/O, and little companion messages
• Check-ins and a study timer
• Home styles, backups you keep yourself, and export or delete everything at any time

Yume Life
A cozy life simulator where you live with your F/O: decorate rooms, visit places, cook, go on dates, play mini-games and earn Yume Coins by playing. No loot boxes, no timers that punish you, no ads and nothing to buy. Yume Life plays the same for everyone.

Yume Garden (optional, 13+)
A moderated community where you can share F/Os, art, writing, designs and shrines with other yumeshippers. Only what you choose to post is uploaded. Sign in with Google to join. Report, block and mute are on everything, there are no follower counts or rankings, and you can download your data or delete your account inside the app.

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

Free and YumeOS Pro
YumeOS is free to use. The free plan includes:
• 3 F/Os (the starter F/Os count, and you can rename and redraw them)
• 40 templates, plus one premium template for 24 hours each time you choose to watch a short ad
• YumeOS classic and 3 more Home styles, and 51 stickers
• 50 photos in each F/O's gallery, 30 collection items, 3 AUs, 2 shrines, 5 companion messages and 5 saved outfits per character
• Instant pretend calls, and one-time planned calls (a short ad gives you 3)
• PNG and JPG exports after a short ad
• Yume Garden: 1 post and 10 kind notes a day
• All of Yume Life, the journal, memories, timeline, chats and backups

The free version shows ads from Google AdMob. Ads never appear inside Yume Life, a chat or a call, or while you are making something.

YumeOS Pro is an optional subscription, monthly or yearly. The price in your currency is shown before you buy. Pro adds:
• All 67 templates, all 11 Home styles and 28 extra stickers
• Unlimited F/Os, gallery photos, collection items, AUs, shrines and companion messages, and up to 30 saved outfits per character
• Polyships: you and two or more F/Os as one ship
• Unlimited planned calls, also daily, on weekdays or weekly
• Home-screen widgets: days together, today's message, your next call
• PDF export, and exports without ads
• No ads anywhere
• More room in Yume Garden, with up to 4 pictures per post

The subscription renews automatically until you cancel it in Google Play. If Pro ends, nothing you made is deleted.

Privacy
Your F/Os, journal, photos and designs never leave your device unless you post them in Yume Garden. For the free version, 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.
