Privacy policy¶
This page explains how information is handled in MindGravity (the Mac app, the Claude extension, and this help site).
Who we are¶
MindGravity is developed and operated by an independent developer, Kazuhiro Uto. Our postal address is available on request and will be provided without delay.
The app does not collect your information¶
- Your maps, project files, settings, and automatic backups are all stored on your Mac.
- The app does not send usage data, error logs, the content of your maps, the content of your Obsidian vault, or file locations to the developer or to any other company.
- The app contains no advertising and no analytics. No account is required.
- The app opens outside pages only when you ask it to, such as a web link or a Help menu item. These pages open in your web browser.
The Claude extension¶
- The MindGravity extension for Claude runs inside the Claude desktop app and talks to MindGravity on the same Mac. It sends nothing to the developer.
- When you ask Claude to read your maps or to make changes, that content is sent to Anthropic through Claude. Anthropic's privacy policy applies to it.
- Using the extension is your choice. All the basic features of MindGravity work without it.
Purchases on the App Store¶
- You get the app and buy Pro through Apple's App Store. Apple handles your payment information; the developer does not receive it.
- The app uses Apple's system to check which products you have bought. The result is used only on your Mac and is not sent to the developer.
- Apple gives the developer aggregated figures that do not identify you (such as downloads and sales). If you have allowed "Share with App Developers" in your Mac's settings, crash reports from the app may also reach the developer. Apple's privacy policy applies to this information.
Contact and bug reports¶
Bug reports and questions are received through a Google Form and by email.
- What we receive: what you write and send in the form or by email, such as the type of request, the app and macOS versions, and what happened, plus your email address if you want a reply. Entering an email address in the form is optional.
- Why: only to reply to you, to investigate and fix problems, and to improve the help.
- Where it is kept: in Google services (Google Forms, Google Sheets, and Gmail). Google's privacy policy also applies.
- Who sees it: only the developer. It is not shared with anyone else, except where required by law.
- How long: deleted one year after your request has been resolved.
- Deletion: contact us at the address below and we will delete it, even before that time.
Before you send a report, please check that it does not include anything you would rather keep private, such as the content of your maps or file locations. If screenshots or logs are needed, the developer will ask you individually.
This help site¶
- This site is served by Google's Firebase Hosting.
- It does not use cookies or analytics.
- To deliver pages, Google may process access records (such as IP addresses and browser types). Google's privacy policy applies to them.
Changes to this policy¶
If this policy changes, we will announce it on this page and update the date below.
