Privacy Policy

Last updated: 28 March 2026

TENNO.DAT (found at tenno.club) is a personal project built and operated by an individual developer. This policy explains what data the site handles and why.

What we collect

Steam authentication

We use Steam OpenID to log you in. This gives us your public Steam ID and display name. We never see or store your Steam password.

Warframe profile data

When you link your Warframe account, we fetch your public profile from the Digital Extremes API. This includes mastery progress, equipment, loadouts, intrinsics, mission completions, and weapon statistics. This data is stored in our database so the site can function.

Prime parts ownership

You can manually track which prime parts you own. This is stored against your account so it persists between sessions.

Session cookies

We set a single session cookie (tenno_session) to keep you logged in. Sessions last 24 hours by default, or 30 days if you choose "remember me". No tracking cookies are used.

Analytics

We use Plausible Analytics, a privacy-focused analytics tool. Plausible does not use cookies, does not collect personal data, and does not track you across sites. All data is aggregated — we see page view counts and referrer sources, not individual visitors.

What we don't do

• We don't sell or share your data with anyone.
• We don't use tracking cookies or fingerprinting.
• We don't serve ads.
• We don't send marketing emails (we don't have your email).

Data storage

This site is built and operated from the EU, and all data is stored on EU-based servers. Your data lives in a PostgreSQL database and is used solely to make the site work. There are no third-party data processors beyond Plausible (analytics) and the hosting provider.

Deleting your data

You can delete your account and all associated data from the settings page. This is immediate and permanent — your profile data, prime parts ownership, and session will be removed.

Changes

If this policy changes, the updated version will be posted here. No smoke and mirrors.
