Privacy Policy

Effective 20 September 2026. Applies to VeloUtils for macOS, all versions.

1. Data we collect

None. We do not collect, receive, store, process or share any personal data, usage data, diagnostic data or identifiers of any kind.

Because nothing is collected, there is nothing to sell, share, link to your identity or use for tracking. In App Store terms, the app's privacy declaration is Data Not Collected.

2. Your documents

VeloUtils runs inside the macOS App Sandbox. It can read and write only the files that you choose — through the system open panel, the system save panel, a drag onto the window, or a file handed to it by Finder. It cannot reach anything else on your Mac.

Your documents are processed in memory on your own machine and are never uploaded. The app never modifies a file you opened. Its only write path is the Mermaid tool's Export, which creates a new PNG or SVG at a location you pick in a save panel.

3. Network access

VeloUtils requests the macOS outgoing-network entitlement for one reason, and we want to be precise about it, because it is the only part of the app that can cause a request to leave your Mac.

The Markdown preview is a real web view. If your own document references a remote image — for example a badge image in a README — the preview fetches that image, exactly as a web browser would. That request goes from your Mac directly to whichever server your document names. The developer neither sees, routes nor logs it. No document content is sent with it.

Clicking a link in the Markdown preview hands the address to your default browser. The preview itself never navigates away.

The Mermaid preview loads its rendering library from inside the app bundle, not from the network, and renders with Mermaid's strict security level. It makes no request of its own.

The Markdown, JSON and CSV tools perform no network access at all.

If you open no document that references a remote resource, VeloUtils makes no network request.

4. What is stored on your Mac

One value: the identifier of the tool that was selected when you last closed the window, so that the app reopens where you left it. macOS stores this in the app's own sandbox container. It contains no document content and no personal data.

VeloUtils writes no other preferences, no caches of your documents, no history and no logs. Deleting the app removes its container.

5. Third-party code and services

VeloUtils integrates no third-party service, SDK, analytics provider or advertising network.

It bundles one open-source library, Mermaid, which runs locally inside the app and is never downloaded at runtime. Mermaid and its dependencies are listed with their licences inside the app, under Help › Acknowledgements.

6. Encryption

VeloUtils implements no encryption of its own. It uses only the encryption that macOS provides, in the form of HTTPS inside WebKit. Its ITSAppUsesNonExemptEncryption declaration is NO.

7. Children

VeloUtils collects no data from anybody, including children under 13. It contains no advertising, no in-app purchases and no user-to-user communication.

8. Your rights

Data-protection rights such as access, correction, portability and erasure apply to personal data that a controller holds about you. We hold none, so there is nothing to disclose, correct, export or delete. If you believe otherwise, write to the address below and we will answer.

9. Changes to this policy

If this policy changes, the revised version appears on this page with a new effective date. Material changes will also be noted in the release notes of the version they accompany.
