Privacy notice (closed test)

Last updated: 18th October 2026

Metis is a physics puzzle game made by ynrie, an individual developer in the United Kingdom ("I", "me"). This notice explains what the closed test of Metis collects about you, why, and what you can ask me to do about it. I am the person responsible for your data (the "controller" under UK data protection law).

What the game collects, and why

What	When	Why
Your Steam ID and Steam display name	When you sign in to publish levels or see other testers' levels	To give you an account, show who made a level, and keep your levels yours
The levels and designs you publish, with their names, descriptions and tags	When you choose to publish	To let other testers find and play them
A problem report: what you wrote, plus the items you chose to include (the level, your design, your settings, the recent log, a screenshot, and your system details: game version, operating system, processor, graphics card and driver, screen size)	Only when you make a report and choose to send it	To find and fix the problem you reported
A crash report: the log of the session that ended unexpectedly	Only when the game offers a report after a crash and you choose to send it	To find and fix the crash
Whether the game simulates exactly as built on your machine (a single "match" or "differs" result)	Inside reports	To catch differences between computers
Technical records kept by the servers, such as your IP address and the time of a request	Whenever the game talks to its servers	To keep the service running and secure

Reports never include your sign-in details, your other levels or designs, or any file outside the game, and your computer's user name is removed from logs before anything is saved.

For now a report is saved as a file on your computer, and you share it in the testers' channel if you want to; nothing is sent until you do. Sending reports straight from the game will come later, and this notice will say so when it does.

The game does not include advertising, does not use analytics or tracking, and I do not sell or share your data for marketing. This website sets no cookies.

Everything else (your unpublished levels, designs, settings and saves) stays on your computer.

The legal basis

I use your data because it is necessary to run the test you have joined and to fix what you report (legitimate interests), and, for reports, because you choose to send them.

Who else handles it

Google (Firebase) stores accounts and published levels on my behalf (and reports, once the game sends them), in London (europe-west2), and serves this website.
Valve (Steam) delivers the game and confirms who you are when you sign in. Steam's own privacy policy covers what Valve does.
Discord hosts the testers' channel, where you share reports and feedback. What you post there is also covered by Discord's own privacy policy.

I do not give your data to anyone else, unless the law requires it.

How long it is kept

Published levels and your account: for the length of the test. Test data may be wiped between versions, and is deleted when the test ends, unless you ask me to keep it or carry it into the released game.
Reports and crash logs: until the problem is fixed, and at most 12 months.
The servers' technical logs (IP addresses and request times, kept by Google for security and troubleshooting): up to 30 days.

Your rights

You can ask me to:

tell you what I hold about you, and give you a copy;
correct it;
delete it (your account, your published levels, your reports);
stop using it.

Email rie@lilysend.com and I will reply within one month. If you are unhappy with how I handle your data, you can complain to the Information Commissioner's Office (ico.org.uk).

Children

The closed test is for invited testers aged 13 or over.

Changes

If this notice changes, the new version will be posted at this address, with the date above updated, and the game's tester notes will say so.
