Privacy.

What this site collects

This policy covers both Element 31 websites: e31.io and the Substrate platform site at e31.ai. They are operated together and behave identically.

These websites carry exactly one form: the savings estimator on the e31.io pricing page asks for a name, work email, and company before it opens. The address is verified first — a one-time six-digit code is emailed to it, and only entering that code opens the estimator and records the three fields with Element 31, so we can follow up about your evaluation. An unverified submission records nothing. Downloading a configuration from the estimator also sends that configuration — the models, the usage, the appliance that fits, and the throughput illustration — with those same details. The details are not sold, not shared, and not added to marketing lists. Until that download, the usage figures you enter stay in your browser.

Beyond that, the measurement is aggregate: we count page views to understand which pages are useful. On e31.io this uses Google Analytics, which loads a script from Google, sets first-party cookies to tell returning visits apart, and reports page views to Google under its own terms. We use it for page counts, not to build a profile of you, and we do not run advertising features on it. e31.ai uses cookieless measurement only.

What this site does not do

• No forms beyond the estimator-access form described above, and no other collection of names, email addresses, or messages.
• No advertising or marketing trackers, and no social media pixels.
• No cookies beyond the Google Analytics cookies on e31.io described above.
• No third-party font CDNs. Fonts are served from this domain. The only third-party script is the Google Analytics tag on e31.io.
• No chat widget, no session recording, and no cross-site identity resolution.

Hosting and server logs

The site is hosted on infrastructure that keeps standard operational logs, which can include IP addresses and request metadata. These logs exist to keep the site available and secure.
