MDit

Privacy Policy

Effective October 14, 2026

Green Balloon (Jungwan Gu) handles information in the MDit app as follows.

What we collect

We do not collect personal data. We run no servers, and the app contains no analytics, advertising or tracking tools.

What stays on your device and iCloud

• Documents (.md files), attached images, chat history and settings are stored on your device, in a folder you choose, or in your iCloud Drive.
• Your ChatGPT connection (sign-in tokens, account email) is stored only in the device keychain.
• Transcription and text recognition in photos run on device. Audio and photos never leave the device.

What is sent to OpenAI

When you connect ChatGPT and use ask, convert or proofread, the following is sent to OpenAI under your own ChatGPT account:

• the questions and instructions you enter
• the document content needed for the answer (the selected documents or relevant parts) and any attached text
• settings needed to produce the answer, such as your writing style

Nothing is sent until you agree when you first connect. The app asks OpenAI not to store responses. OpenAI's handling is governed by OpenAI's privacy policy and your ChatGPT settings.

• Recipient: OpenAI (United States)
• When: each time you use an AI feature, over the internet

You can disconnect at any time in the app under Settings › AI.

Local integration on the same Mac

If you turn on Settings › Integrations on a Mac, tools running on the same Mac can read the documents you allow and propose changes. The connection stays inside that Mac (127.0.0.1) and requires an access token.

Feedback

If you send feedback by email from the app, we use your address and message only to reply and delete them once handled.
