What the game and this website collect, why, where it is kept, and how to have it deleted. Last updated 27 September 2026.
The short version. The game sends us nothing unless you say yes. If you do, it sends notes on how you played, so we can find where the demo goes wrong. The notes carry no name, no email and no Steam account. You can change your mind at any time, and we will delete what you sent if you ask.
Broadband Architect is made by Kolva Ltd, a one-person studio in Gloucestershire, England. Kolva Ltd is the controller of the data described here. For anything on this page, email hello@broadbandarchitect.com.
While you play, the game writes a notes file for each session into
%APPDATA%\altnet\sessions on your own computer. The files are plain text,
you can open or delete them, and they stay on your computer unless you agree to send them.
The first time you start the demo, a card asks Help us fix the demo? If you answer yes, the next time you start the game it sends us the notes from your earlier sessions. They contain:
They do not contain your name, your email, your Steam account, your files, details about your computer, or anything you do outside the game window.
If you answer no, nothing is sent. You can change your answer at any time in Settings › Playtesting.
Crash reports. If the game falls over, or closed unexpectedly last time, a card offers to send a report. It is sent only if you press Send, whatever you answered before. It contains that session’s notes, the error, and any comment you type.
Feedback. If you said yes, you can send us a note from the game (F8, or Send feedback on the pause menu). It carries what you type, where you were in the game (town, day, cash, speed, the tool in hand), and, for bug reports, a picture of the game window if you leave that box ticked.
We use this only to find and fix what goes wrong in the game. We do not sell it, share it, use it for advertising or build profiles from it. The notes, reports and feedback are sent on the basis of your consent: your yes on the card, or your press of Send.
It is kept on our own server in Helsinki, Finland, rented from Hetzner Online, inside the EU. Only the developer reads it.
We keep session notes, crash reports and feedback while the game is in development, and delete them no later than 12 months after we receive them.
Like any web server, ours records the IP address that each upload and page request comes from, to keep it running and secure (our legitimate interest). Those logs are deleted automatically after 14 days and are never matched to your notes.
Because we do not know who you are, the install id is the only way we can find your notes.
Open any file in %APPDATA%\altnet\sessions. The first line holds
"install": followed by your id. Email it to
hello@broadbandarchitect.com and we will
delete everything sent under it and confirm when it is done. Turning sending off in
Settings › Playtesting stops anything further being sent.
If you get the game through Steam, your account, purchases and wishlist are handled by Valve under the Steam Privacy Policy. Steam gives us only totals (how many people wishlisted or played), never who you are, and the game never reads your Steam account.
This website sets no cookies and runs no analytics or tracking. Two outside services are involved:
A few people test early builds from a private link with a personal key. Those builds work the same way, except that the key tells us which tester the notes came from.
Under UK data protection law you can ask to see, correct or delete what we hold about you, and you can withdraw your consent at any time. Email hello@broadbandarchitect.com. If you are unhappy with how we have handled it, you can complain to the Information Commissioner’s Office at ico.org.uk.
