silent data collection. You know exactly what runs your AI.\n\n- **Clear monthly pricing** — One fee covers platform access and AI credits. No hidden costs.\n- **Open-weight only** — DeepSeek, Llama, Mistral, Qwen, and more via [OpenRouter](https://openrouter.ai). No closed-source models. Aggregate usage is publicly visible on the [OpenRouter app page](https://openrouter.ai/apps?url=https%3A%2F%2Fgithub.com%2Fchuk-development%2Fchuk_chat) — token totals and models, zero personal data.\n- **Privacy first** — Encrypted chats, no tracking, no profiling. Built like a tool, not a marketing funnel.\n- **Your data, your control** — We store nothing you don't want. Fully deletable. Fully controllable. Fully yours.\n\n## Features\n\n### Core\n- **End-to-End Encryption** — Server-synced chat data is encrypted client-side with AES-256-GCM before upload\n- **Cross-Platform** — Android, iOS, Linux, macOS, Windows, and Web\n- **Real-Time Streaming** — Watch AI responses as they're generated, with streaming preserved across chat switches\n- **File Attachments** — Share images, PDFs, and documents with AI\n- **Offline Support** — Access your chat history without a connection, with automatic network recovery and plaintext local cache for instant loading\n\n### AI Tools\n- **Tool Calling** — Built-in tool system with registry, executor, and per-tool settings. AI can call tools and display results inline\n- **AI Image Generation** — Generate and edit images directly in chat\n- **Interactive Maps** — AI responses with `\u003cmap\u003e` blocks render inline maps with markers, places, and route polylines\n- **Interactive Charts** — AI responses with `\u003cchart\u003e` blocks render inline charts (bar, line, pie, scatter, radar)\n- **Weather Cards** — AI responses with `\u003cweather\u003e` blocks render rich weather cards with hourly forecast\n- **Email Drafts** — AI responses with `\u003cemail\u003e` blocks render email cards with \"Open in Mail App\" button\n- **Spotify Control** — Play, pause, search, manage playlists and volume via OAuth-connected Spotify\n- **Calendar \u0026 Reminders** — Create calendar events (native on Android/macOS, .ics on Linux/Windows) and set alarms/timers with notifications\n- **Web Search \u0026 News** — Brave-powered web and news search with freshness controls\n- **Weather, Places, Calculator, QR Codes, Notes** — Expanding set of built-in tool handlers\n- **Multi-Pass Tool Call Rendering** — Interleaved content blocks show text and tool calls in correct chronological order with collapsible UI\n\n### Account \u0026 Privacy\n- **Multi-Step Account Deletion** — GDPR-compliant three-step deletion flow with password confirmation\n- **In-App Update Checks** — Automatic version checking against GitHub Releases with platform-specific download links (APK, DEB, AppImage, DMG, EXE)\n\n### UI \u0026 UX\n- **Theme Customization** — Colors, backgrounds, dark/light mode, visual effects\n- **Redesigned Reasoning UI** — Expandable accent-tinted cards for model reasoning and tool call details\n- **Mobile Three-Pill Input** — Redesigned mobile input bar with separate attachment, text, and action pills\n- **Audio Visualizer** — Gradient glow waveform with exponential scaling for voice recording\n- **Unified Image Preview** — Consistent image viewer across desktop and mobile with copy-to-clipboard support\n- **Debug Chat Copy** — Copy full chat contents (including reasoning, tool calls, model info) to clipboard for debugging\n\n## Security \u0026 Privacy\n\n- **Client-side encryption** — Chats synced to the server are encrypted on your device before upload\n- **Zero-knowledge architecture** — We cannot read your chats, even if the server is compromised\n- **Plaintext local cache** — Previously loaded chats are also cached locally in plaintext for instant loading and offline access; this cache is protected by your device account and OS sandbox, not by the chat encryption layer\n- **Certificate pinning** — Protection against MITM attacks, including WebSocket connections\n- **Image validation** — Magic-byte verification on uploaded images\n- **No logging in production** — All debug logs are disabled in release builds\n\n\u003e **If you lose your password, all your chats are permanently lost.** There is no recovery mechanism by design — this ensures maximum privacy. Choose a strong password and store it safely.\n\n### What is encrypted\n\n| Data | Storage |\n|------|---------|\n| Chat messages | Encrypted before sync/storage on the server (AES-256-GCM). Previously loaded chats are also cached locally in plaintext for instant loading and offline access |\n| Chat titles \u0026 metadata | Encrypted on the server. When cached locally for faster loading, they are stored in plaintext |\n| Starred chat status | Encrypted on the server. When cached locally, it is stored in plaintext |\n| Your encryption key | Stored locally only and never synced to the server. Uses secure storage where available, with local app-storage fallback on some desktop builds |\n\nFor detailed security information, see [SECURITY.md](SECURITY.md).\n\n## Pricing\n\n**€20/month** — all models, all platforms.
