Duel privacy policy

Effective: 2026-10-25

This policy covers the Duel game. It says what data the game keeps, what it sends to us, and what you can do about it.

The short version: Duel sends us nothing unless you turn it on. There are three switches, and all of them start off. You can change them at any time in Settings.

Who we are

Duel is made by Drew Williams, a sole developer in the United States ("we"), who decides what happens to the data described here. For anything about your data, write to privacy@drewwilliams.dev.

What stays on your computer

The game keeps these files in its settings folder. None of them is sent anywhere unless a switch below says so.

• Settings: your sensitivity, video, audio and interface choices, and your answers to the three switches.
• Match records: the inputs and game state of each match you play, so it can be replayed. A record names players only by a key made for that one match. It holds no account, Steam ID or computer name.
• Logs: recent lines about what the game was doing.
• Crash reports: when the game crashes, it writes a folder describing the crash (see below). It does this whether or not you allow crash reports to be sent, so you can attach one to a bug report yourself.

You can delete any of these files. The game recreates what it needs.

What we collect if you turn it on

Crash reports

Off until you turn it on. With it on, the game sends each new crash report to us the next time it starts. A crash report contains:

• what crashed and where in the game's code (a panic message and stack, or a minidump: a snapshot of the game's memory at the moment of the crash)
• the match record up to the crash
• the last log lines
• the game version, operating system and version, graphics card and driver, and your game settings
• the command line the game was started with

Before sending, the game removes folder paths that contain your user name. A crash report does not include your name, an account or Steam ID, or other files from your computer. A minidump holds the game's own memory. In rare cases that can include text you typed into the game.

Why: to find and fix crashes. A match record lets us replay the exact match that crashed.

Legal basis: your consent (GDPR Article 6(1)(a)). You can withdraw it at any time by turning the switch off. Reports already sent stay until they expire (see "How long we keep it").

Who handles it: crash reports are stored with Sentry (Functional Software, Inc.), which processes them for us under a data processing agreement. Sentry stores them in the United States. Transfers from the EU and UK rely on the EU-US Data Privacy Framework and its UK extension, and on standard contractual clauses. Sending a report means your computer connects to Sentry, so Sentry sees your IP address. We set Sentry not to store it.

Performance telemetry

Off until you turn it on. Duel does not collect this yet; the switch is there so you only have to choose once. When it does, it will send numbers about how the game runs, such as frame times and your hardware, with no account or Steam ID, so we can find setups where the game runs badly. We will update this policy first, and say exactly what is sent.

Public stats

Off until you turn it on. Duel has no website or accounts yet, so nothing is published. When it does, this switch lets your match stats appear on the Duel website. We will update this policy first, and say exactly what is shown.

What we never do

• Sell or share your data for advertising.
• Collect anything without a switch you turned on, except what any internet connection reveals (your IP address) when the game does send something.
• Build a profile of you across other games or websites.

How long we keep it

• Crash reports: 30 days after we receive them, then Sentry deletes them.

Your rights

Wherever you live, you can:

• Turn any switch off in Settings. Nothing more is sent from then on.
• Ask what we hold about you, ask us to delete it, or ask us to correct it, by writing to privacy@drewwilliams.dev. Crash reports carry no name or ID, so to find yours we need something to match on, such as the time of the crash. If we can't tell which reports are yours, we can't return or delete them.

If you are in the EU or UK, you also have the rights the GDPR gives you, including to object to or restrict our use of your data, and to complain to your data protection authority. If you are in California, the CCPA gives you similar rights. We do not sell or share personal information as the CCPA defines those words.

Children

Duel is not meant for children under 13, and we do not knowingly collect data from them. If you are under 16 and live in the EU or UK, ask a parent before turning on any of the switches. If you think a child under 13 has sent us data, write to privacy@drewwilliams.dev and we will delete it.

Changes to this policy

If the game starts collecting something new, it will be behind a switch that starts off, and this policy will say what it is before the game sends any of it. We will change the date at the top of this page whenever we change the policy.
