Doppler records the history of Counter-Strike artifacts. To do that it reads a limited set of public data from Steam. This page explains what it collects, how it is used, and what it will never do.
When you sign in with Steam, we receive your public SteamID, profile name, and avatar, and we read your public CS2 inventory through Steam’s Web API. We store the artifacts in that inventory, the Doppler handle you claim, and any display name or bio you choose to add. We keep a single session cookie so you stay signed in.
We do not collect private Steam data, payment details, or anything beyond what Steam exposes publicly and what you choose to provide.
Your data builds and maintains your archive — its identity records, provenance timeline, recognitions, and market-value observations — and operates the registry itself. That is the whole of it.
We never sell or rent your data. We never trade, list, modify, or touch anything in your Steam inventory — our access is strictly read-only. We do not run advertising and we do not track your behaviour across other sites.
Doppler is a registry, so your /@handle archive page is public — it shows your catalogued artifacts, recognitions, and provenance. Catalogue only what you are comfortable having on the public record.
We rely on a small set of infrastructure providers who process data on our behalf: hosting (Vercel), database (Neon), background processing (Inngest), and market-value context (CSFloat). Each handles data under its own terms.
One cookie: an encrypted session cookie that keeps you authenticated. No third-party advertising or tracking cookies.
You can request deletion or export of your account and archive at any time by emailing hello@joindoppler.com. We will remove your account and the records attributed to it.
If this policy changes, we will update this page and its effective date. Material changes will be made clear.
