WitNote Data Flow

WitNote is a local-first Markdown writing and knowledge workspace for Mac, iPhone, and iPad. No account is required to use WitNote. Documents, imports, exports, settings, and model files are handled on the device or in a file location the user selects. WitNote does not run advertising or track you, and does not maintain a server-side writing profile.

Local files and foldersMac uses the files and folders the user chooses through macOS file access. iPhone and iPad use app storage and files the user opens through the system file picker. The user remains responsible for backups, permissions, and imported or exported content.

Local AI inferenceOn supported physical devices, the built-in MLX model processes prompts and responses locally. The local model does not send document text to a hosted AI service.

OllamaOn Mac, WitNote can connect to an Ollama service running on the same Mac. That connection is restricted to localhost addresses and is not a Hooosberg-hosted service.

App settings and model selectionStored locally so the app can remember workspace and interface preferences and the selected model. Mac can also remember locally available Ollama models.

User-Configured Cloud APIs

Where this feature is available, WitNote can connect directly to a cloud API endpoint chosen and configured by the user. WitNote is not an AI API provider and does not proxy cloud requests through a Hooosberg server. On Mac, the user chooses the endpoint URL, model ID, and API key; the API key is stored in macOS Keychain on that Mac, not in a WitNote account or Hooosberg database.

When the user sends a cloud-AI request, the submitted text and model response travel directly between the app and the configured endpoint. On Mac, sending attached current-document content is off by default and requires separate permission for that endpoint. On iPhone and iPad, text submitted in a connected chat is sent to the chosen provider; do not submit content you are not permitted to send. The provider's own privacy policy applies.

WitNote does not retain cloud request bodies or API keys on a Hooosberg server. The configured provider may process, retain, or use data according to its own terms and settings; its retention and deletion practices are outside WitNote's control. On Mac, removing an endpoint deletes its locally stored API key, and the document-content permission can be disabled at any time.

Local AI and Model Downloads

WitNote uses native Apple-platform interfaces and a local MLX inference route on supported Apple Silicon devices. A small Qwen3 0.6B 4-bit model is bundled so a new user can start without a first model download. Optional model downloads are performed only when the user selects a model or retries a download; the downloaded files are saved locally and are not uploaded by WitNote.

MLX and Qwen are third-party open-source or model projects with their own notices and license terms. The app package includes third-party notices and the bundled model's license files. User-downloaded models remain subject to the model source's license, acceptable-use rules, and any attribution requirements. See MLX and the Qwen3 model page for source information.

In-App Purchases

The optional WitNote Pro lifetime purchase, shared across Mac, iPad, and iPhone, unlocks format conversion and export and is handled by Apple App Store and StoreKit. WitNote uses StoreKit to verify the purchase and restore it on a user's Apple account. Hooosberg does not receive the user's Apple ID, payment method, billing address, or App Store credentials. Refunds, billing questions, and account-level purchase records are handled by Apple.

Third-Party Notices

The installed Mac and mobile apps include a ThirdPartyNotices.txt file and bundled Qwen3 LICENSE and NOTICE files. MLX, Qwen, and any subsequently downloaded model are credited separately from WitNote's own application code. Users should review the relevant source notice before redistributing model files or generated packages.

Network and External Links

WitNote may use the network for user-initiated model downloads, Apple StoreKit purchase or restore flows, pages the user explicitly opens, Mac-local Ollama, and a user-configured cloud endpoint where that feature is available. The core Markdown workspace and local inference path are designed to work without a Hooosberg cloud account. External services process data under their own terms when the user chooses to access them.

Platform Services

When you download, purchase, update, or review WitNote through Apple App Store, Apple may process account, payment, device, crash, or store activity data under Apple's own privacy policy. WitNote may access the network for user-initiated model downloads, Apple StoreKit purchase or restore, pages the user explicitly opens, a local Ollama service, or a cloud API endpoint that the user configures. WitNote does not require a Hooosberg account, run advertising, or maintain a hosted user profile.
