What we collect
WM Arena is an open-source benchmark. We collect the minimum data needed to operate and improve the site:
- Anonymous visitor ID: a random identifier stored in your browser's localStorage so we can count unique visitors and prevent duplicate votes. It is not linked to your identity.
- Interaction events: quiz completions, blind battle votes, and share clicks. These include the anonymous visitor ID but no personal data.
- Email address: only if you choose to sign up for the WM Arena newsletter. We use it solely to send you new-model and milestone announcements. You can opt out at any time by emailing hi@worldflux.ai.
What we do not collect
- We do not sell or rent your email to anyone.
- We do not use invasive fingerprinting.
- We do not store your name, location, or any profile information unless you explicitly send it to us.
Cookies and local storage
We use localStorage for the anonymous visitor ID and to remember your quiz / battle session state. We use Cloudflare Analytics for aggregate traffic data. No third-party ad cookies are set.
Data retention
Interaction events and aggregate stats are retained indefinitely so we can publish historical performance. Email records are kept while you remain subscribed. To have your email removed, contact hi@worldflux.ai.
Your rights
You can request deletion of your email or visitor history at any time by emailing hi@worldflux.ai. We will process requests within 30 days.
