Privacy Policy

Last updated: 4 August 2026

Short version: the log analyser does not store your logs, we do not run analytics or advertising of any kind, the desktop application does its work on your own machine, and if you gave us your email you can delete it yourself with one click.

Who we are

ModTamer is provided by Arturo von Senger, an individual based in Chile. For any question about your data, write to contact@modtamer.com.

The free log analyser

When you paste a log on the home page, the text is sent to our server, analysed in memory, and discarded. It is never written to a database or to a file. There is no account, and nothing links an analysis to you.

Crash logs frequently contain absolute paths that include your operating system username (C:\Users\yourname\...). Before returning anything, we replace those paths. We do this because the result is what you are likely to copy into a public Discord to ask for help, and your username is not a cost you should pay for using the tool.

The waiting list

If you give us your email address to be told when ModTamer launches, we store:

• the address itself, in lowercase;
• the date you signed up;
• which page you signed up from;
• a random token that makes your removal link work.

That is the whole record. We use it for one message, when the product launches. No newsletter, and it is never sold, rented or shared with anyone.

Every message we send carries a link that removes you, with no account and no password. That link also offers full deletion — not just "stop writing to me", but "delete the address entirely". They are different requests and we treat them as different. You can also just email us.

The desktop application

ModTamer is local-first by design. Reading your mods, building the dependency graph, booting test servers, isolating the mod that breaks a pack and measuring performance all happen on your own computer. Your mod list, your world, your configuration files and your logs do not leave your machine.

Only two things reach the network, and this is the complete list:

• A version check. On startup the application asks our server which version is current, so it can tell you if yours is old. It sends nothing about you or your servers, and if there is no internet it simply stays quiet and keeps working.
• Downloads you ask for. When you accept a repair or an update, the application downloads those mod files from their public source (such as Modrinth), the same way your browser would.

If usage telemetry ever exists, it will be opt-in and clearly described. It will not be switched on quietly in an update.

What we do not do

• No advertising, and no advertising identifiers.
• No analytics or tracking scripts. Not ours, and not anybody else's.
• No cookies for tracking. The site works without setting any.
• No selling, renting or sharing of personal data. Ever, to anyone.
• No profiling and no automated decisions about you.

This is enforced in code, not just promised here: the site declares a content security policy that forbids loading any script from another host, and asks intermediaries not to modify our pages. When our own CDN tried to inject an analytics script, the policy blocked it and we removed it.

Server logs

Our web server keeps ordinary access logs to diagnose faults. Visitor IP addresses are masked before being written, so they cannot identify an individual.

Who else touches the data

Because the server is in the United States, data from the waiting list is stored there. When payments begin, Paddle will act as merchant of record and will handle your payment details directly — we never see or store your card.

How long we keep things

• Logs you paste: not kept at all.
• Waiting list: until you remove yourself, or until the launch message has been sent and the list is no longer needed.
• Access logs: a short period, and with the IP already masked.

Your rights

You can ask to access, correct, delete or export your data, or object to its use. Write to contact@modtamer.com and we will answer. For the waiting list you do not have to ask anybody — the link in the email does it immediately.

Depending on where you live you may also have the right to complain to a data protection authority.

Children

ModTamer is a tool for running game servers and is not directed at children under 13. We do not knowingly collect their data.

Changes

If this policy changes we will update the date at the top. If a change actually affects what we do with your data — rather than just wording — and we have your email, we will tell you.
