We don't want your data.

Last updated: July 2, 2026

The one-sentence version

Marquee has no account system, no analytics SDK, no crash reporter, and no ad network — it reads your local games, occasionally asks the internet for cover art, and otherwise minds its own business.

What Marquee stores, and where

Everything Marquee knows about your library lives on your own Mac, in two places:

• UserDefaults (com.marquee.gaming-launcher) — your favorites, hidden games, sort/theme/view preferences, play counts, and accumulated playtime.
• ~/Library/Caches/Marquee/ — downloaded cover art, banners, and hero images, cached locally so Marquee doesn't re-download them every launch.

None of this ever leaves your Mac. There is no server that Marquee reports back to.

What network requests Marquee actually makes

Marquee talks to the internet for exactly one reason: fetching cover art and game metadata for the games it finds on your machine. Specifically:

• Steam's public store API — searches for a matching title and fetches box art, screenshots, and trailer URLs. No Steam login involved; these are the same public endpoints Steam's own store search page uses.
• DuckDuckGo image search — only when you manually use "Fix Cover Art…" and choose the web search tab.
• SteamGridDB — entirely optional, and only if you paste in your own API key during onboarding or Preferences. Off by default.

None of these requests include anything identifying you personally — just a game title. Nothing is sent about your hardware, your usage patterns, or your identity.

What Marquee never does

• No analytics, telemetry, or crash reporting SDKs of any kind
• No advertising, no ad IDs, no tracking pixels
• No account creation, login, or cloud sync
• No selling, sharing, or monetizing any data — there isn't any to sell

Game launching

When you press PLAY, Marquee hands off to the relevant storefront or process (CrossOver's Wine, Steam's own URL scheme, Epic's launcher, or macOS itself for native apps) — Marquee doesn't sit in the middle of your game session collecting anything once it starts, beyond timing when the process starts and stops so it can show you real playtime later, and knowing when to fade the music back in.

Open source

Marquee's full source is available on GitHub. If you don't take our word for any of the above, you're welcome to read the code yourself — that's kind of the point.

Changes to this policy

If this ever changes, this page changes with it, and the "last updated" date at the top will say so. Given the whole app is a hobby project with no business model, we don't expect much to change.
