TexMacgic Privacy Policy
Effective date: August 25, 2026
Operator: Ming Hei Wong
TexMacgic is a local, native macOS LaTeX editor. It contains no advertising, cross-app tracking, third-party analytics, or developer-operated crash reporting. The developer does not receive your documents or usage data. Editing, TeX compilation, Git tools, and Apple Intelligence run on your Mac. If you deliberately enable Power User mode and send a request, the separately installed AI provider you select may receive the content needed for that request under your account with that provider.
Information stored on your Mac
TexMacgic works with files and folders that you select. It may store local settings, recent-project references and app-scoped security bookmarks, source history and recovery copies, preview caches, templates, gallery items, project to-do entries, and agent chat history so requested features can work. These local stores are not uploaded to a TexMacgic server. Deleting local app data does not delete source documents that you saved elsewhere on your Mac.
Apple Intelligence
On a compatible Mac running macOS 27 or later, TexMacgic can use Apple’s on-device Foundation Models for reviewed image-to-LaTeX transcription and focused writing tasks. Version 1.0 has no Private Cloud Compute route. Screen capture occurs only after you choose Capture Region and grant macOS permission; TexMacgic captures the selected region once. The reviewed image and generated text remain on the Mac unless you copy or insert the result.
Optional Power User providers
Power User mode can invoke Codex from OpenAI, Claude Code from Anthropic, or Antigravity from Google. TexMacgic does not bundle a provider account. You install and sign into the selected command-line tool separately. Before the first provider request, TexMacgic names the providers, explains what may be shared, and requires your permission. You can revoke that permission in Settings > Intelligence; revocation blocks new requests, stops active provider work, and disables external MCP access.
For a request you initiate, the selected provider may receive:
- your prompt, retained conversation context, and optional standing instructions;
- selected text, attached files or images, and project content needed for the task;
- compiler diagnostics, build logs, PDF or source renderings, MCP tool inputs and results, and output from commands you approved;
- rendered or annotated images used for AI Touch Up; and
- short excerpts from the first user and assistant messages when TexMacgic asks the provider to suggest a chat title.
The provider tool runs with your project as its working directory and may inspect additional project files needed for the task. If you enable Bypass permission, it can run native commands and access data allowed by macOS with fewer per-action prompts. Provider processing, retention, model-improvement choices, and account linkage are governed by your provider settings and policy: OpenAI, Anthropic, and Google. TexMacgic’s developer does not operate those services or change your provider privacy choices.
Local MCP service and build tools
When enabled, the MCP control service listens only on 127.0.0.1 at a random port and requires random
instance and turn credentials. It is intended only for an agent running on the same Mac. Tool content
remains local until a provider requests a result, at which point that result can become part of the
provider request described above.
LaTeX compilation uses the compatible MacTeX, TeX Live, or TinyTeX distribution installed and enabled by you. TexMacgic does not upload documents for compilation. Shell escape and custom build scripts are user-enabled local automation; TexMacgic displays warnings and requires a trusted per-project opt-in. Those scripts may read files or use the network according to their own commands.
Analytics, advertising, tracking, and updates
TexMacgic contains no advertising SDK, product analytics, cross-app tracking, developer-operated crash reporter, or GitHub update client. Mac App Store updates are delivered by Apple. Apple may process App Store downloads, purchases, or crash information under Apple’s policies and user settings; TexMacgic does not receive personal data from Apple for analytics or advertising. TexMacgic does not sell personal information.
Your choices and deletion
You can use AI Off, revoke provider permission, delete chat sessions, clear Recent projects, remove trusted-project decisions, and inspect or delete local history. Templates and user-added TikZ gallery items can also be removed. A provider may separately retain data under its account controls and policy; use that provider’s privacy tools for those copies.
Security, children, and changes
The Store edition uses the macOS App Sandbox, security-scoped access to folders you select, explicit capability consent, project-containment checks, and authenticated loopback access. No storage or transmission method is perfectly secure. TexMacgic is a general-purpose scientific writing and productivity tool and is not directed to children. This policy may change when features or practices change; the effective date will be updated.
