This site collects one thing: the email address you give us to hear about Knowtank.

• What we keep. Your address and the time you signed up.
• What we use it for. Telling you about Knowtank. We don't sell it or share it.
• Who handles it. Cloudflare carries the site's traffic and delivers your signup to our mailbox. OVH hosts the site.
• What we don't do. No cookies, no analytics scripts and no ads. Cloudflare keeps aggregate traffic counts, and it briefly uses your IP address to limit abuse of the form.
• Removal. Write to hello@knowtank.app and we'll delete your address.
• The app. There's no app yet. This page will change before the app asks for your photos.
