Privacy Policy

Last updated: 15 October 2026 · Version 13

The short version. Reminth has no analytics, no crash reporting and no advertising. What the launcher stores stays on your computer, and we never receive it. The one exception is your Reminth account (Discord, Google or email): we keep your gamer tag, picture, how you sign in and when you signed in - and for email sign-in your address and a scrambled form of your password. You can delete it yourself at any time. The launcher talks directly to the services it needs (Microsoft, Mojang, Modrinth, GitHub and so on), listed below. The only personal data that ever reaches us is what you choose to send us, such as an email. You have full rights over that data under the GDPR, and you can complain to a data protection authority at any time. This summary is for convenience; the full text below is what applies.

1. Who is responsible for your data

Reminth (the launcher and this website) is run by Lefteris Psilopanagiotis, an individual developer based in Greece (“we”, “us”). For the purposes of the EU General Data Protection Regulation (GDPR) and Greek Law 4624/2019, we are the controller of the personal data described in section 3.

Contact for anything in this policy: reminthsupport@gmail.com. We are not required to appoint a Data Protection Officer and have not done so.

NOT AN OFFICIAL MINECRAFT PRODUCT. NOT APPROVED BY OR ASSOCIATED WITH MOJANG OR MICROSOFT.

2. The principle this policy follows

This page describes what the code actually does. Reminth is built so that we don't need your data: the launcher reports nothing to us beyond your Reminth account (section 3c), there is no tracking, and no selling or sharing of personal data with anyone. We do not use your data for profiling or automated decision-making.

3. Personal data we process

a) Visiting this website

The site runs no analytics, trackers or advertising, uses no local storage and loads no third-party fonts or scripts. It sets no cookies unless you sign in to a Reminth account (section 3c); those cookies are strictly necessary for signing in and are never used for anything else.

c) The Reminth account

The launcher asks you to make a Reminth account (or sign in to yours) the first time you open it, before you connect Minecraft; the same account works on this website. You sign in with Discord, Google or an email address and password. If our account server can't be reached, the launcher still works.

b) Contacting us

If you email us, we receive your email address, your name if you include it, and whatever you write. Purpose: answering you, and dealing with privacy requests, bug and security reports, legal or takedown notices. Legal basis: our legitimate interest in replying (Art. 6(1)(f)); where your email relates to a purchase, performing our contract with you (Art. 6(1)(b)); and complying with legal obligations (Art. 6(1)(c)). Retention: we delete the conversation 12 months after it ends, unless we need to keep it longer to deal with a legal claim. Our email provider stores it on our behalf as a processor.

If you open an issue on the Reminth GitHub repository, it is public and handled by GitHub under its own terms. Don't post personal details there; email us instead. We will delete or hide issues we control on request.

4. The launcher: what stays on your computer

Everything the launcher saves lives on your own computer, mainly in %APPDATA%\Reminth, which also holds your instance folders. None of it is uploaded or sent to us. We have no access to it.

To fill in Home, your instances and Player Statistics, the launcher reads your worlds, server lists, statistics, logs and mod files in its own game folders. This happens locally.

5. The launcher: what it sends, and to whom

The launcher has no telemetry, analytics, crash reporting or tracking. Each request goes directly from your computer to the service involved. We are not involved in these requests and never see them. Each service is responsible for what it does with the request under its own privacy policy. All of them can see your IP address, as with any request on the internet.

Mods you install are made by third parties and may make their own network requests once the game is running. Reminth's own HUD mod runs locally and sends nothing anywhere, with one exception you can switch off:

The launcher itself does the same for you, from Reminth 1.8.0:

6. Paid features

Reminth+ and Reminth Hosting are not available yet, and nothing can be bought. Before any paid feature launches, this policy will be updated to say exactly what data it needs (for example, the details our payment provider needs to process your payment), who processes it and for how long, and you will see that before you pay.

7. Children

Playing Minecraft requires a Microsoft account, and Microsoft applies its own age rules and parental controls. A Reminth account is meant for people at least 13 years old (or older where local law says so), like Discord and Google accounts. Reminth does not ask your age and does not knowingly collect personal data from children below that age; if that happened, we delete the account. If you are under 15, please ask a parent or guardian before emailing us. A parent or guardian who believes their child has sent us personal data can ask us to delete it.

8. Your rights

Under the GDPR you have the right to:

Email reminthsupport@gmail.com to use any of these rights. It's free, and we answer within one month (extendable by two months for complex requests, in which case we'll tell you why). We may ask you to confirm your identity first.

Data that only exists on your own computer (section 4) is fully under your control: sign out to delete the stored account file, or delete the %APPDATA%\Reminth folder (and Videos\Reminth if you used streamer mode) to remove everything the launcher has written. Back up any worlds first, since this deletes them too.

Right to complain. You can complain to the Hellenic Data Protection Authority (Αρχή Προστασίας Δεδομένων Προσωπικού Χαρακτήρα), Kifisias 1-3, 115 23 Athens, Greece, www.dpa.gr, or to the data protection authority in the country where you live or work. We'd appreciate the chance to fix the problem first, but you don't have to contact us before complaining.

9. Security

Sign-in tokens are encrypted on your computer by Windows, as described in section 4. Minecraft's own files, its libraries and assets, Mojang's Java runtime, and everything downloaded from Modrinth or listed in a modpack are checked against the checksum their source publishes. A few sources publish no checksum: the performance mods when they come from GitHub (only as a fallback, see section 5), the fallback Java download from Microsoft, and some mod-loader files. Those are downloaded over an encrypted connection from the project's official location. Reminth checks that every performance mod is actually built for your Minecraft version and loader before keeping it, and installs only stable releases of the performance pack, never alpha or beta builds. The launcher contacts only the services listed above, over encrypted connections where the service supports them (Minecraft servers use the game's own protocol). No system is perfectly secure; if you find a security problem, please email us privately instead of posting details publicly.

10. Things Reminth changes on your computer when you ask

Nothing here is sent anywhere. It is listed because it changes how Minecraft runs or what is on your disk: (a) the Java settings Reminth starts Minecraft with are chosen per Java version, and you can pick the garbage collector in Settings; (b) with the setting on (it is on by default) Reminth asks Windows to run Minecraft one step above other programs, never higher, and not while streamer mode is on; (c) when you create an instance and pick the Max FPS or Far view profile, Reminth writes a starting options.txt into that new instance only if no options.txt, world or game log exists there, and never changes one that exists; (d) “Choose graphics card…” only opens Windows' own graphics settings page and shows you the path to copy; Reminth does not change that setting or write to the Windows registry; (e) “Boost FPS…” in an instance's menu shows the video settings it would change, changes them in that instance's options.txt only after you press “Change them” and never while the game runs, and keeps your old values so you can put them back; (f) with ReminthHUD in an instance, it starts Just Enough Items (JEI), if you have it, about a second and a half after you join a world or server if JEI has not started by then, using JEI's own start-up action, so JEI's loading does not freeze the game later; this can be switched off with "jeiEarlyStart": false in config\reminthhud.json; (g) since Reminth 1.4.2 the installer puts Reminth in your own user folder (%LOCALAPPDATA%\Programs\reminth-launcher) instead of C:\Program Files, so installing and updating no longer need administrator rights. If an older all-users copy is found, Windows asks once and the installer removes that old copy; your instances, worlds and settings in %APPDATA%\Reminth are kept.

11. Changes to this policy

When what Reminth does changes, this page changes with it and the date at the top moves. If a change affects your data in a significant way, such as a new feature that stores data off your computer, we will announce it in the launcher and on this site before it takes effect, not as a quiet edit.
