# JabJab

**Privacy-first XMPP messenger for Android.**
No data harvesting. No ads. No accounts sold. Ever.

JabJab is a hard fork of [Conversations](https://codeberg.org/iNPUTmice/Conversations) — the gold-standard open-source XMPP client — extended with stickers, stories, microblogging, dynamic reactions, themes, app lock, and a built-in updater.

## What's new in JabJab

Everything in Conversations, plus:

### 🎭 Stickers
Custom sticker packs — send, receive, and create your own. Stickers are stored on your device and never sent to third parties. Uses WebP for small file sizes.

### 📸 Stories
Ephemeral photo and video stories that vanish after 3 days. Share moments without the algorithm pressure — no like counts, no engagement metrics. Compatible with Monocles and other pubsub-social-feed clients.

### 📝 Microblog
Publish long-form posts via XMPP PubSub (XEP-0277). Posts appear at [blog.xmpp.tel](https://blog.xmpp.tel) and are federated — readable by any XMPP client that supports PubSub. Offline drafts sync automatically when you reconnect.

### 😄 Dynamic Reactions
React to any message with any emoji. Reactions are tracked per-message, per-account, and sync across devices.

### 🎨 Themes
Seven built-in themes including light and dark variants. Adjustable bubble shapes and font size.

### 🔐 App Lock
PIN lock with biometric unlock support. Lock the app automatically on background.

### 🔄 Built-in Updater
Checks for new APKs in the background and installs in one tap — no app store required.

### 🔀 Multi-Share
Share a file or text to multiple contacts at once from inside the app or directly from your gallery. Files are uploaded once and forwarded — no duplicate uploads.

### ⏩ Audio Speed
Playback speed toggle for voice messages: 1× / 1.5× / 2×.

### 🌐 Message Translation
Built-in translation for incoming messages — read in your language, reply in theirs.
