Privacy
How mattthew.co handles data. Last updated 5 October 2026.
01The short version
- No cookies, no ad trackers, no profiles.
- To see how far people get through the site, I record which part a visit reached and whether it was on a phone or a computer — with no way to tell who you are.
- Your IP address is used for a moment to keep out spam and is never stored.
- If you send a brief, I get what you wrote and the contact you left — and use it only to reply.
- Some cursors and part of the “online” count are simulated to make the site feel alive.
02Who I am
This is the personal site of Matt Prokofev, a designer. I am responsible for the data described here. Questions or requests: write to me through the brief form on this site, or on Telegram or LinkedIn (links at the top of the page).
03How far you scroll
The site notes the furthest part of the page a visit reached (the forest, the city, space, works, testimonials, FAQ, the brief) and whether it was on a phone or a computer. A visit is a random number made up when the page opens; it lives only in the page’s memory and is gone when you leave or reload. I use these numbers to see where people stop and make the site better. They are kept for 12 months.
04Keeping out spam
When a new visit starts, your IP address is turned at once into a scrambled code using a secret key that changes every day. The IP address itself is not stored anywhere. The code only lets the site limit how many visits one source can make in a day; the codes and the key are deleted after that day, and only anonymous daily totals remain (how many visits, how many were stopped). This is done to protect the site.
05Stars
In the sky at the bottom of the page you can leave one star per visit. What is saved is its position and the time; stars are visible to everyone and say nothing about you. So that you can see your own star, your browser tab keeps a random number for it in session storage, which is cleared when you close the tab.
06Who’s online
The online indicator shares, live and anonymously, which part of the page you are on with the browsers of other visitors at the same moment. Nothing about it is saved. To keep an empty site from feeling empty, some cursors moving around the page and part of the online count are simulated — they are not real people, and they step aside as real visitors arrive.
07When you send a brief
I receive what you typed (what you need, the timeline, a few words) and the one contact you chose — email, Telegram or LinkedIn. It is stored so I can reply, and a notification is sent to my Telegram. I keep briefs for up to 24 months, then they are deleted; ask me and I will delete yours sooner.
To keep out bots, your browser solves a small puzzle while you fill in the form — about a second of computing, nothing to click. The puzzle is a random code from the site; it is stored with the brief only so it cannot be used twice, and says nothing about you. I also note which page the brief came from: the main site or the plain-text page (/ai).
08Cookies
The site sets no cookies. The only things kept in your browser are the star number described above and a few site settings — sound, theme, whether you have seen the intro and where you left the main page — which stay on your device and are never sent anywhere.
09Services that help run the site
These companies process data for me only to deliver the site, and see your IP address the way any web server does when your browser loads something from them:
- Framer — hosting of the site.
- Supabase — the database and the brief form (servers in the EU, Ireland); its network runs through Cloudflare.
- Telegram — notifications to me about new briefs.
- esm.sh and unpkg — delivery of code libraries the site loads.
- Spline — 3D scenes on the page.
- Google Fonts — the typeface of the plain-text page (/ai).
10Why this is allowed
Scroll statistics, spam protection, stars and the online indicator rely on my legitimate interest in running and improving a site that people visit by choice, done in a way that does not identify you. Briefs are handled because you asked me to get back to you.
11Your rights
You can ask what I hold about you, ask me to correct or delete it, or object to how it is used. Briefs I can find by the contact you left. Visits and stars are not linked to you in any way, so I cannot pick out yours — which is the point. If you think something is wrong, you can also complain to a data protection authority.
12Changes
If the site starts doing something new with data, this page will say so first, with a new date at the top.
