calclark.app drops no advertising cookie until you say yes in the cookie banner. These optional partners are all off until you allow them: AppsFlyer (which link or campaign brought you to the app), Google Advertising Products, Meta (Facebook and Instagram), TikTok and X. Google, Meta, TikTok and X use a pixel: it lets us show our ads again to people who visited this site, and tells us if those ads work. If you allow Meta or TikTok and join the waitlist, they also get a scrambled (hashed) copy of your email address, so they can count the signup. The banner lists every partner and what it does. If we add a tool, this page will name it.
Cookieless measurement
We count page views with Vercel Web Analytics. It sets no cookie and reads nothing from your device. It does not follow you across sites. It tells us which pages people open, the country, the browser and the device type. Because it stores nothing on your device, it runs for every visitor.
Your cookie choice
The banner saves your choice in one cookie, calclark-cookie-consent, for 12 months. It is essential, because without it we would ask you on every page. Change your choice any time: .
What happens when you join the waitlist
You type an email. We store that address and send one email to confirm it. When you confirm, we tell you when the app is live. That is a form submission, not a tracking cookie. Details in privacy.
What the browser may still store
Short-lived files the site needs to load (session, security). They are not used to profile you.
Nothing we use to remarket Cal Clark on other sites.
The mobile app
The iOS and Android app is not this website. Crash reports and optional usage stats are described in privacy. There is no advertising identifier for tracking.
How to clear cookies
Use your browser settings. Blocking all cookies can break sign-in on other sites. It will not hide the waitlist form here.
Cal Clark treats body metrics and meal logs as health-related data. The articles below are the published texts we follow. Official sites do not allow us to show their pages inside ours, so we quote the published wording here.
Strictly necessary cookies do not need consent. Analytics and advertising cookies do. calclark.app does not set advertising cookies. Vercel Web Analytics counts visits without cookies. Analytics cookies load only after you say yes in the banner.
