Terms of Service

Last updated: 4 August 2026

Who provides ModTamer

ModTamer is provided by Arturo von Senger, an individual based in Chile. Contact: contact@modtamer.com.

When paid plans become available, purchases will be handled by Paddle acting as merchant of record. That means Paddle is the seller for your purchase, handles payment and applicable taxes, and its terms also apply to the transaction.

Current status

ModTamer is in development and not yet on sale. The free log analyser on this site works today and is free to use. Everything below about licences, plans and payments describes how it will work when it launches.

What ModTamer is

A desktop tool that diagnoses, repairs, validates and measures modded Minecraft servers (Forge and NeoForge). It works on isolated copies of your server: your original folder is never modified during analysis or testing.

When you explicitly ask it to apply changes to your real server, it takes a backup first, and it writes only mod files inside the mods folder — never your world, your configuration or your server properties. If the backup fails, nothing is applied.

What ModTamer does not promise

We would rather lose a sale than make a claim we cannot defend. Specifically:

• We do not promise that any modpack will be stable, bug-free, or free of crashes. What we verify is that a server started successfully under the conditions we tested.
• Performance figures are estimates under a documented scenario. Real player counts depend on your hardware, your world, your network and what players actually do.
• We do not promise universal compatibility. The combinations of loader and Minecraft version we actually test are listed publicly on the home page. Outside them ModTamer may work, but nobody has verified it.
• "Registered" is a fact we can check; "works" is not. ModTamer can confirm that a server knows about a mod's content. Whether a feature behaves correctly in play depends on the game.

Mods belong to their authors

ModTamer does not host or redistribute mods. When you accept a repair or an update, it downloads files from their public source on your behalf, the same way your browser would.

You are responsible for complying with the licences and terms of the mods you install. ModTamer is not affiliated with Mojang, Microsoft, the Forge or NeoForge teams, Modrinth, CurseForge, or any mod author.

Your licence

When you buy a plan you get a personal, non-exclusive, non-transferable licence to use ModTamer, for personal or commercial purposes, on the number of machines your plan allows.

You may not:

• share, resell or publish your licence key;
• circumvent licence checks or plan limits;
• redistribute ModTamer as your own product.

If you change computers you can release an activation from your account and use it elsewhere. We would rather you did that than be stuck.

Working without a connection

ModTamer does the heavy work locally, so it keeps working when our servers do not. The licence is checked periodically, and there is a generous grace period during which the application continues to work normally without reaching us. An outage on our side is not supposed to stop you from fixing your server.

Your responsibilities

ModTamer changes files on servers you control. Although it works on copies and takes a backup before applying anything, you should keep your own backups. Software fails, disks fail, and a tool that touches your files is not a substitute for your own copy.

Suspension

We may suspend a licence that is being shared publicly, used to attack our services, or used in a way that breaks the law. Where the situation allows it, we will tell you first and give you a chance to fix it.

Liability

ModTamer is provided "as is". To the extent the law allows, our liability is limited to the amount you paid us in the twelve months before the claim. Nothing here limits liability that cannot be limited by law, and if you are a consumer, your statutory rights are unaffected.

Ending the agreement

You can cancel at any time. See the refund and cancellation policy.

Governing law

These terms are governed by the laws of Chile. If you are a consumer, this does not deprive you of the protection of the mandatory rules of the country where you live.

Changes

We may update these terms. If a change materially affects your rights and we have your email, we will tell you before it takes effect.
