what is achievement-scavenger fr?

Achievement Scavenger is a desktop companion app for people who like to fully complete their games. It sits alongside whatever you are playing on Steam, PlayStation, Xbox, or RetroAchievements and gives you a live, always-on-top window showing your achievement or trophy progress as it happens. The app automatically detects which game you are running and switches to that game's tracker. As you play, it polls for new unlocks and shows a toast notification the instant something pops, and it can even snap a desktop screenshot with the unlocked achievement's icon overlaid on top. To connect to each platform, you provide your own credentials: a Steam Web API key, a PlayStation NPSSO token, an OpenXBL key for Xbox, or a RetroAchievements account. Beyond raw tracking, the app pulls in community written guides. These combine step by step walkthroughs, embedded media, checklists for collectibles and side quests, and warnings for missable achievements you could permanently lock yourself out of. Hints are blurred until you hover over them so you can avoid spoilers if you want. You can organize achievements into custom chapters that follow your story progress, keep a personal watchlist, and add your own private notes to any entry. Other conveniences include Discord Rich Presence so friends can see what you are hunting, a compact mini mode overlay, several visual styles with adjustable transparency, a global hotkey to show or hide the window, and cloud sync of your settings and history across devices using GitHub Gists. You can also export your checklist as JSON or a shareable HTML page. The app is built with Tauri, meaning a Rust backend paired with a React and TypeScript frontend, and currently targets Windows because Steam detection relies on the Windows registry. It is released under the GNU General Public License, and the community achievement database that powers its guides lives in a separate linked repository that anyone can contribute to.
