DET-33 privacy policy
DET-33 doesn't know who you are. There are no accounts, no player identifiers, and nothing the game sends can be tied to you or your Steam profile. This page lists everything that leaves your machine and why.
What the game sends
Aggregate play statistics. Counters like total runs started or total time in combat go to Steam as aggregated stats. Valve sums them across all players before we ever see them; there is no per-player version on our side. Your own numbers are visible on your Steam profile's stats page, so nothing is recorded that you can't inspect yourself.
One run summary per run. When a run ends, the game posts a short summary (difficulty, weapon, build picks, outcome) to our own server so we can balance guns and cards. The summary carries no identifier of any kind: no install id, no session id, no run seed, no timestamp finer than the day it arrived. Two summaries can't even be linked to each other, let alone to a person, and the server never reads or stores your IP address. This is the one thing you can turn off, in Settings under DATA: "Share anonymous run summaries."
Crash reports. If the game crashes or hits an error, a report goes to Sentry so the bug gets fixed. On the public branch these reports carry no user record at all, and file paths that would contain your system username are scrubbed before anything is sent.
There is nothing to delete on request, because nothing is tied to you in the first place.
The beta branch
The opt-in beta branch is the exception: crash reports there include an install id plus your Steam persona name and account id, so I can follow up with you about the bug you just hit. If you'd rather not, play the default branch.
What Steam collects
Valve collects its own data (playtime, achievements, and so on) under the Steam Privacy Policy. That's between you and Valve; this page doesn't cover it.
