This is a personal portfolio, so there isn't much to tell, but here's all of it.
What I collect
Nothing that identifies you. There are no accounts, no forms and no cookies, and the site doesn't store anything in your browser.
Analytics
I use Vercel Web Analytics to see which pages get visited. It doesn't use cookies and doesn't follow you across other sites. For each page view it records the page, the site that sent you there, your approximate location (country, region and city), and your browser, operating system and device type. Vercel tells repeat visits apart with a hash of the request that it discards after 24 hours, so I only ever see totals, never individual visitors. Vercel describes this on its analytics privacy page.
Hosting
The site is hosted by Vercel. Like any web host, its servers handle your IP address to deliver pages, and Vercel may keep logs to run and secure its service, under its own privacy policy.
Fonts
Every font is served from this site. Nothing is loaded from Google Fonts or any other font service.
Figma embed
The Vivacity case study can show a live Figma file. It only loads if you choose "Load the Figma file", and from then on Figma's privacy policy applies to that frame.
The upload demo
Files you try in the FileUploadBlock demo never leave your browser. Nothing is uploaded or saved.
Links elsewhere
Links to LinkedIn and Google Docs take you to those services, and email links open your own mail app. Each of those has its own privacy policy.
Questions
Since I don't collect anything that identifies you, there's nothing to look up, export or delete. If you have a question anyway, email me at thomasrichardson.contact@gmail.com.
