This Privacy Policy explains how MNTX ("we," "us," or "our") handles information collected through the Concrete website at joinconcrete.app (the "Site"). We keep this simple because, at this stage, we collect very little.
When you join the waitlist, we collect the email address you submit. We do not ask for your name, payment details, or any other personal information on the Site.
We use your email address solely to:
We do not sell, rent, or share your email address with third parties for their own marketing.
Waitlist emails are stored using Supabase, a third-party database provider that hosts data on our behalf. Supabase processes this data subject to its own security and privacy practices. We restrict access so that the list cannot be read publicly.
The Site does not use advertising or tracking cookies. Any hosting provider serving the Site may collect basic, non-identifying technical logs (such as IP address and browser type) for security and performance, as is standard for websites.
You can ask us to remove your email from the waitlist at any time by contacting us at the address below, or by using the unsubscribe link in any email we send. Once removed, your email is deleted from our waitlist.
We keep your email only as long as needed to operate the waitlist and notify you about launch. If Concrete does not launch, or you ask to be removed, we delete your email.
The Site is not directed to children under 13, and we do not knowingly collect information from them.
We may update this policy from time to time. The "Last updated" date above reflects the most recent revision.
