Data privacy

In short: AMMC sends one small message when it starts, so we know which versions and platforms are in use and can tell you when a newer release is out. It contains no personal data and no timing data. --skip_telemetry_upload turns it off.

Your passings never leave your network. AMMC reads the decoder and writes to your console, your database, your WebSocket clients and your UDP listeners — nothing else. There is no cloud service in the data path, and AMMC works with no internet connection at all.

What is sent

Once, at startup, over HTTPS to logs.ammconverter.eu:

Field	Example	Why
`version`	`7.9.1/2339ab3`	Which release is running, so we can support it and offer an upgrade
`app`	`ammc-amb`	Which binary — converter, Vostok converter or simulator
`os`	`windows`	Which platforms to keep building and testing
`arch`	`x86_64`	Same, for 32/64-bit and ARM
`decoder_type`	`amb`	Which decoder families are actually used
`db_type`	`mysql`	Only the scheme of the connection string — `mysql`, `postgresql` or empty. Never the host, database, user or password
`machine_uuid`	`c6266ca0-…`	A machine identifier, so that one PC restarted ten times is not counted as ten installations

That is the whole message. A real one looks like this:

{
  "machine_uuid": "c6266ca0-5674-4afc-9286-38d351428779",
  "version": "7.9.1/2339ab3",
  "app": "ammc-amb",
  "os": "windows",
  "arch": "x86_64",
  "decoder_type": "amb",
  "db_type": "mysql"
}

The reply carries the current release number, which is how AMMC prints

New version 7.9.2 available, download from https://ammconverter.eu

The upload runs on a background thread and AMMC never waits for it. If the machine is offline the attempt fails silently and everything else keeps working.

What is never sent

Passings — transponder numbers, times, codes, hits, strength, passing numbers
Decoder ID, decoder IP address, or anything else about your network
Database connection strings, hostnames, usernames or passwords — only the scheme, mysql or postgresql
Track ID, track name and layout values from --trackId and friends
Your name, email address, company, computer name, user name or IP-based location
The contents of any log file. --verbose output stays on your machine

Nothing is collected while AMMC runs — there is no periodic reporting, no heartbeat and no usage statistics. One message per start, and that is all.

About the machine identifier

machine_uuid is the identifier the operating system already assigns to the computer: IOPlatformUUID on macOS, /etc/machine-id on Linux and MachineGuid from the registry on Windows. AMMC reads it, it does not create it.

It is a device identifier, not a person. It is not linked to a name, an account or an email address — we have no accounts, and AMMC asks you for nothing. It is however stable for as long as the operating system is installed, so repeated starts on the same PC can be recognised as the same PC. If you would rather not send it, use the switch below.

Records are kept as an appended log line with a timestamp, used only in aggregate to count versions and platforms. They are not shared with, sold to or combined with anything from third parties, and there is no advertising or analytics network involved.

Turning it off

Add --skip_telemetry_upload and nothing is sent at all:

ammc-amb.exe --skip_telemetry_upload 10.0.11.10

or set the environment variable once, for a service or a shortcut:

set AMMC_SKIP_TELEMETRY_UPLOAD=true
ammc-amb.exe 10.0.11.10

The switch works on every binary — ammc-amb, ammc-vostok and ammc-sim — and is checked before anything is prepared, so no message is built and no connection is opened. Nothing else changes: the only thing you lose is the notice about a new version.

This website

Separate from the converter, ammconverter.eu itself is a static site — plain files, no accounts, no login, no forms and no server-side processing of anything you do.

Nothing you enter or read is collected, stored or sold.
Nothing is shared with advertising companies.
Nothing is mined for personal or behavioural profiling.
Nothing is monetised.

No cookies, and no analytics. The site sets nothing in your browser and runs no tracking of any kind. Google Analytics was removed in August 2026.

No third-party requests. Every stylesheet, font, script and search index comes from this domain — nothing is fetched from a CDN, an analytics service or an advertising network, so no other company learns that you visited. Search runs entirely in your browser against an index downloaded with the page; what you type into it is never sent anywhere.
