steamid.one Terms of Service

steamid.one is a free web service that resolves, converts, and displays publicly available Steam profile data. The following tools are free to use without an account:

• Steam ID Lookup — resolve any Steam ID format, vanity URL, or profile link to all five formats (SteamID64, SteamID3, SteamID32, hex, and profile URL).
• Format Converter — single and bulk conversion between every Steam ID format.
• Profile Comparison — side-by-side comparison of two Steam profiles.
• Analytics Dashboard — playtime totals, inventory overview, friends list, and Steam level (requires Steam sign-in).
• Live Resolver — a public endpoint at /api/resolve for programmatic lookups.

steamid.one is not affiliated with or endorsed by Valve Corporation. Steam, the Steam logo, and all related trademarks are the property of Valve Corporation.

You agree not to misuse the service. Prohibited conduct includes:

• Automated scraping, crawling, or bulk querying beyond what the bulk converter is designed for.
• Attempting to disrupt, overload, or compromise the performance or security of the service.
• Using the service to harass, stalk, or harm any individual.
• Circumventing rate limits or caching mechanisms.
• Any use that violates applicable law or Steam's own Terms of Service.

We reserve the right to block access for any use we determine to be abusive, at our sole discretion and without notice.

Sign-in is optional and provided through Steam OpenID. When you sign in:

• You are redirected to Steam's own authentication page. We never see, handle, or store your Steam password.
• After successful authentication, Steam returns only your public SteamID64 to us.
• We use that SteamID64 to load your public profile and to associate your saved theme preference with your account.

We store as little as possible. Here is exactly what we hold:

• Session cookie — a short-lived cookie that keeps you logged in during your visit. Cleared on logout or session expiry.
• Theme preference — your chosen colour theme, stored in our database linked to your SteamID64. Deleted on request.
• Steam API cache — publicly available Steam profile data is temporarily cached in our Redis database to reduce API load and improve response times. Cache expires automatically and is not shared.

We do not sell, rent, or share your data with third parties for advertising or profiling purposes.

steamid.one relies on a small number of third-party services to operate:

• Steam Web API (Valve Corporation) — all profile data is fetched from Steam's public API in real time.
• Vercel — hosting, deployment, and privacy-friendly anonymous analytics (no cookies, no personal data).
• Upstash — serverless Redis used for temporary Steam API response caching.
• Neon / PostgreSQL — cloud database used to store user theme preferences.

We are not responsible for the content, policies, or practices of any third-party service.

The service is provided "AS IS" and "AS AVAILABLE" without any warranty of any kind. All Steam data is fetched from Valve's public API and we do not guarantee its accuracy, completeness, or timeliness. We are not liable for any actions taken based on information displayed on this site.

In no event shall the site owner be liable for indirect, incidental, special, consequential, or punitive damages arising from your use of or inability to use the service.

The steamid.one website, its design, code, and original content are the exclusive property of the site owner and are protected by copyright. You may not reproduce or redistribute any part of the service without prior written consent.

These Terms are governed by the laws of Australia, without regard to conflict of law principles.

We may update these Terms at any time. Material changes will be reflected in the "Updated" date at the top of this page. Continued use of the service after changes constitutes your acceptance of the updated terms.
