What this site keeps about you.
This is my site, and I measure who reads it: which pages, for how long, and when I can tell, who you are or where you work. I use it to decide what to write and whom to follow up with. Nothing here is sold, shared, or sent to an ad network.
Counting visits
Vercel Web Analytics and Vercel Speed Insights count page views and measure how fast pages load. They use no cookies and report totals, not people.
The visitor id
A first-party cookie named al_vid, with a copy in your browser’s local storage, holds a random id for up to 400 days. On your device the site also keeps the page you first landed on, the site that sent you, any campaign tags on that first link, and a list of the last 60 pages you read here.
When you leave a page, your browser sends my server a short note: which page, how many seconds it was on screen, how far you scrolled, and which links or buttons you clicked. What happens to that note depends on the next three sections.
When I know who you are
That happens one of two ways. You opened a link I sent you, which carries a short code (?via=) that says who I sent it to. Or you typed your email into a form here that asks for it, like the full build on The First Email or The Flow Ledger.
From then on, visits from that browser are saved under your name or email: the pages, the time on each, how far you scrolled and what you clicked, plus the pages on your device’s list from before. Each visit also records your approximate location (city, region, country), the name of the network you were on, your browser, operating system, screen size, time zone and language. Location and network are worked out from your IP address during the visit. The IP address itself isn’t saved.
When you’re on a company network
If the connection belongs to an organization’s own network (a company, a university or a government office), the visit is saved with that organization’s name even if I don’t know who you are. The name comes from the public registry of who owns each block of IP addresses. Home internet providers, phone carriers, VPNs and cloud hosts don’t count.
Everyone else
On a home or phone connection, before I know who you are, my server looks up whose network the note came from and throws it away. Nothing about the visit is kept beyond the totals in “Counting visits”.
What’s never collected
- What you type into the tools. The calculator’s numbers and The First Email’s fields stay in your browser. The only form value the site reads is the email address in a form that asks for your email, when you submit it.
- Keystrokes, screen recordings, or the text on the page you were reading.
- Ad pixels, data brokers, or anything shared with a third party.
Who sees it, and for how long
Only me, in a private dashboard. It’s stored with Vercel, which hosts this site, and deleted 400 days after your last visit.
Having it deleted
Email andrew@growthlegend.com and I’ll delete what’s kept about you. Clearing this site’s cookies and storage gives your browser a new id that isn’t linked to the old one.
