Privacy

Short version: we keep very little, we use it only for our research and to reply to you, we never sell it, and if you ask us to stop, we stop.

What we collect

If we invite you to a research conversation, we found your name, role, company and work email through a professional connection or a public source such as your company's website. If you email us or agree to talk, we also keep your messages and our notes from the conversation. If you use the Scorecard, we count completions in aggregate; if you subscribe to the newsletter, Substack handles your subscription under its own privacy policy. This site uses no advertising cookies or ad trackers. Like any website, our hosting provider processes basic technical data such as IP addresses to deliver and secure the site.

How we use it

We use it to reply to you, schedule and run research conversations, and learn how hardware teams prove market fit. Anything we publish from research is anonymized and never names you or your company without your written permission.

Sharing

We don't sell or rent your information. We share it only with the service providers that run our email and website, and only as needed to operate them.

Your choices

You can ask us at any time to see, correct, or delete what we hold about you, or to stop contacting you. Email research@essanar.com and we'll act on it within two business days. If you ask us to stop contacting you, we stop the same business day, on every channel.
