Privacy Policy
In short: DrillMaster receives your SteamID, your public Steam profile and your CS2 match stats. We never see or store passwords, and we don't sell your data to anyone. Updated: 25 July 2026.
What data we collect
- Steam profile. Sign-in works through official Steam OpenID: you enter your password on steamcommunity.com and it never reaches us. From Steam we receive your SteamID64, public nickname and avatar.
- Match stats. By your SteamID we request your public CS2 match stats (score, K/D, ADR, aim metrics) via a third-party stats service — named in the "Third-party services" section below.
- Your activity. Which plan items you completed or skipped, notes on your training, settings (time zone, training days) and your ratings of the AI analyses.
- Technical. Server logs (IP, request timestamps) — to protect against abuse and to debug failures.
How the data is used
- Match stats are aggregated into a summary that the AI coach uses to build its analysis and weekly plan. Only aggregated numbers go to the LLM provider (DeepSeek), and your SteamID is not shared.
- The public player/match counter on the landing page shows totals only, with no nicknames.
- Your data is not sold or shared with third parties, other than the services listed below that the site can't run without.
Third-party services
- Steam (Valve) — OpenID authentication.
- Leetify — source of match stats.
- DeepSeek — the LLM behind the AI analysis; receives only aggregated in-game metrics.
- Yandex.Metrica — site analytics with Webvisor: it records the content of the pages you view and your actions on them (mouse movement, clicks, scrolling). We use it to understand what people use and what to fix. The data is processed by Yandex under its own policy.
Cookies
The site sets an authentication cookie (so you don't sign in every time; it lasts up to 30 days), an anti-forgery cookie (form protection) and Yandex.Metrica cookies.
Storage and deletion
Data is stored on our server, which only the service owner can access. Backups are made daily and stored locally by the service owner. Your account and all its data are deleted on request to the service owner — in full: profile, match history, plans and check-offs.
