Settings & updates

• Theme — System / Light / Dark. The whole launcher is in the visual language of stygion.eu.
• Density — comfortable / compact.
• Whole-app scaling — a slider, persisted.
• Language — complete Czech and English.
• Window size — the launcher opens at about 85 % of your screen (at least 940 × 600), centred; drag to resize.
• Motion — short transitions; when your system asks for less motion the launcher does not move at all. You can turn them off.
• Sounds — short sounds on press, finish and error, made inside the launcher, nothing downloaded. Default volume 25 %; switch them off here.

• A Feedback button in the titlebar (or Settings → Support).
• After signing in with STYGION ID: bug / feedback / question → a ticket on the web + a Discord channel for the team.
• You pick the ticket type with pills (not a native dropdown).

• Java — Auto (the launcher manages it) or a path of your own.
• Memory — Auto, or a value of your own. Auto gives instances with mods 75 % of the computer's RAM (up to 12 GB; at least 3 GB always stay for the system), while plain Minecraft stays at 2–3 GB. What you set yourself is not changed. Below 16 GB of RAM the game starts with 1 GB and grows when it needs to.
• JVM args — the default is Recommended: a set worked out for the Java that actually runs the game (client-tuned G1, compact object headers on Java 25, generational ZGC only for a big pack on a strong machine). An older saved "None" reads as Recommended; your own flags stay.

The Windows installer and the AppImage update themselves on launch: download, install and relaunch — all in-app. You see the changelog before installing. The Updates page shows channel status and a manual check.

Releases are driven by internal Release Control (channels alfa / beta / stable), so you get the build from the channel that suits you.

Who updates depends on where you got the launcher. A copy from a store (Microsoft Store, Flathub) or a package manager is updated by that source, not by the launcher: Settings → Updates shows who does it instead of the channels.

We take it seriously:

• Telemetry is anonymous and can be switched off — it is on by default, and you turn it off in the Privacy section of settings. It sends version, channel, OS/arch and a random install_id. No personal data, IP not stored.
• Error reports, only if you agree. The launcher asks once whether it may send a short description when something breaks (a launcher crash, a failed start or install, the cause of a game crash). No name, accounts, file paths or IP. Off by default; change it anytime in Settings → Privacy.
• Friends can see what I play and Discord Rich Presence are two separate switches, both yours.
• Discord Rich Presence (on by default, can be switched off in Settings → Privacy; switching it off clears the card on Discord at once) shows on your Discord profile that you are playing, only while the game runs: the instance name, "On …" (the address of the server the launcher joined for you) or "In the menu", the time since the game started, a STYGION MC or Minecraft image and two buttons linking to stygion.eu (STYGION MC and the Launcher). It goes only through your own running Discord (a local connection) and nothing is sent to our servers; the launcher reads nothing from Discord. The card follows the launcher language. Without a running Discord nothing happens.
• Badges have their own settings in Settings → Badges: who sees them (Public / Friends / Nobody), hiding a single badge, the public leaderboard, notices. All in Badges.
• The benchmark has its own settings in Settings → Benchmark. No hidden benchmark or hardware scan: a measurement starts only on your command, the result stays with you until you send it yourself (with consent and a view of exactly what is sent), and a sent run can be withdrawn and unlinked from your account. Passive measurement is off by default. All in Performance and the benchmark.
• A clear notice on first run (GDPR legitimate interest).
• A crash log is uploaded to mclo.gs only after your second confirmation, with tokens, UUIDs and your home folder hidden first.

Version, channel, links and the state of the services. It says the launcher is not an official Minecraft product and is not approved by Mojang or Microsoft. The Support button (the heart in the side rail) opens stygion.eu: the launcher is free and stays free; donations pay for servers and development. Experimental features (today: Potato Mode) are switched on here.

• Keyboard shortcuts (configurable, with a cheatsheet).
• Guided tour over finished features.
