Read [The YumeBee Usage Guide](https://yumebee.app/usage-guide/) for a complete, specific answer to "how do I use YumeBee" — it covers signup, the single-device model, adding friends, 1:1 and group chat, reactions, watch cards, catalog and custom stickers, the share extension, every setting in the app, exactly what is and isn't end-to-end encrypted, and account recovery. It also ends with a short FAQ section restating the most-asked questions and answers directly. ## Get the app YumeBee is released and free on both stores: - iOS — App Store: https://apps.apple.com/in/app/yumebee/id6780577476 - Android — Google Play: https://play.google.com/store/apps/details?id=app.yumebee Published by YuMe Network Private Limited. Listed in India for now, matching where sign-up works. ## Key facts - One active device per phone number — signing in on a new phone replaces the old device. - Text and photo messages are end-to-end encrypted (Signal protocol); typing, read receipts, presence, and watch cards are not encrypted (server-visible). - All messages and photos disappear 24 hours after being sent, delivered or not. - Group chats support 2 to 20 people (including the creator). - Any message can be reacted to with an emoji (hold the message), in 1:1 and group chats. One reaction per person per message. The emoji and which message it is on are end-to-end encrypted; only the author of the reacted-to message is notified. - Winks (view-once photos/videos taken in the app's own camera) build a "streak": a running count of the consecutive days everyone in a chat winked. A 1:1 needs both people; a group needs every member. Each day is a rolling 24-hour window from the last completed round, plus a few silent extra hours so a late notification doesn't break a streak. Sending a wink is what counts — opening one does not, because the server never learns whether a wink was opened. The server stores only a count and the window times per chat, never a record of individual winks. - No voice or video calling. - No chat history or backup — a new device only sees messages sent after setup. - Signup is phone number + SMS OTP, no password. Available in India only for now (Indian +91 numbers). - Minimum age is 13. Users can block and report others from inside the app (profile, long-pressed message, group member row, or a stranger's preview screen); the report sheet leads with a Child safety category. ## Pages - [Home](https://yumebee.app/): product overview - [Usage Guide](https://yumebee.app/usage-guide/): the complete how-to-use reference, including a FAQ - [Our values](https://yumebee.app/values/): company values - [We are paranoid](https://yumebee.app/paranoid/): privacy/security positioning - [Terms & Conditions](https://yumebee.app/tnc/): terms of service - [Privacy Policy](https://yumebee.app/privacy/): what data is collected, what E2EE hides, retention periods, and who it's shared with - [Delete account](https://yumebee.app/delete-account/): the exact in-app steps to delete a YumeBee account, and what happens when you do - [Child Safety Standards](https://yumebee.app/child-safety/): published CSAE standards — what's prohibited, the 13+ age floor, how to report child sexual abuse or exploitation, how we respond, and the designated contact
