Data Policy

We keep the site lightweight and privacy-first. Here is what the site may store in your browser:

What we store (client-side only)

  • Session storage (temporary, clears when you close the tab):
    • mm_start_here_dismissed โ€” remembers if you closed the optional โ€œStart Hereโ€ modal.
  • Theme preference (existing feature):
    • mm-theme (localStorage when available; falls back to a short-lived cookie only if storage is blocked) โ€” remembers light/dark choice.
    • Managed by shared/js/theme-persistence.js; no analytics are attached to theme choice.

What we do NOT store

  • No tracking cookies.
  • No third-party advertising pixels.
  • No cross-site identifiers.

Third-party services

  • Altcha analytics loads only on the production domain (not on localhost or file://). It tracks page views and basic usage for site improvement; it does not set tracking cookies.

Your controls

  • You can dismiss the optional โ€œStart Hereโ€ modal; the dismiss memory is limited to your current browser tab.
  • To clear theme preference, remove the mm-theme entry from your browserโ€™s storage (or block site storage entirely).

If you have questions or need changes, please open an issue on GitHub or contact us via the siteโ€™s Contact page.
