BestClient

Privacy Policy

Last updated 12 August 2026

Who this is about

BestClient is a Minecraft launcher and client made for the bestpvp.eu server. This page explains exactly what the launcher sends, what the server at client.bestpvp.eu stores, and what you can ask to have removed.

For anything on this page, write to [email protected].

What is stored on our server

Only what the friends system needs to work. When you sign in through the launcher, the following is written to our database:

• Your Minecraft account UUID and username. The UUID identifies you; the username is what your friends see.
• A session token. A random value so the launcher does not have to sign in again on every request. It expires after 30 days.
• Your friend list and pending friend requests - pairs of UUIDs.
• The server address you are currently on, and a timestamp. This is what makes a friend show as online and lets you see where they are. It is overwritten each time it updates and is treated as offline after 90 seconds.

That is the complete list. We do not store your email address, your password, your IP address, chat messages, or anything about what you do inside the game.

What never leaves your computer

• Your Microsoft password. Sign-in happens through Microsoft's own device-code flow. You type your details on Microsoft's website, never in the launcher.
• Your Microsoft and Minecraft access tokens. These are held on your machine so the game can start.
• Your settings, HUD layout, play-time history and logs, kept in %APPDATA%\.bestclient.

Why we are allowed to hold it

Under the GDPR our basis is performance of a contract: you asked for a launcher with a friends list, and a friends list cannot work without knowing who your friends are and whether they are online. If you do not want any of it stored, do not sign in - the launcher still installs and starts the game.

How long it is kept

• Session tokens - 30 days, then they stop working.
• Presence (server address and timestamp) - overwritten continuously; only the most recent value exists.
• Account record and friend list - until you ask for deletion.

Other services the launcher talks to

The launcher makes requests to these on your behalf. Each one sees your IP address, as any website you visit would:

• Microsoft and Mojang - signing in and downloading Minecraft itself.
• Modrinth - searching for and downloading mods. Mods are fetched from Modrinth directly so their authors get the download.
• GitHub - checking for launcher updates and downloading them.
• Fabric - the mod loader's version metadata.
• mc-heads.net - rendering the small player heads next to friend names.
• Cloudflare - sits in front of client.bestpvp.eu.
• Discord - only if you turn on Discord status. It runs through the Discord app already on your computer, and shows only that you are playing.

We do not use analytics, advertising, or tracking of any kind, on this website or in the launcher. There are no cookies on this site.

Your rights

You can ask us to show you everything we hold about you, correct it, or delete it. Write to [email protected] from an address we can tie to your account, or ask through the bestpvp.eu Discord, and include your Minecraft username. Deletion removes your account record, your session, your presence and your friend links, and cannot be undone.

If you are in the EU and you think we have handled your data badly, you can complain to your national data protection authority. In Hungary that is the NAIH.

Age

BestClient is not aimed at children under 13. If you are under the age at which you can agree to this on your own where you live, ask a parent or guardian first.

Changes

If this policy changes, the date at the top changes with it. If the change is significant, it will be mentioned in the launcher.
