Privacy
What this site collects, why, and what happens to it. In plain words.
Who I am
This is Kaz Kato’s personal site, KATO-SAN. I’m the only person who reads what you send through it. Email hello@katosan.co.uk about anything on this page.
What the forms collect
- Starting a conversation: your first and last name, email, company if you give it, what you’d like me to add value to, and, only if you tick the box, your WhatsApp number.
- Joining my network: your first and last name, email, and if you give them, your company and what you do.
- Asking a question: the question, and your email if you want to know when it’s answered.
- Entering the free build: your first and last name, email, your idea and the problem it solves, and if you give them, your company, who it’s for and a link, plus the version of the free build terms you agreed to. Those terms let me talk about your project in public; your idea stays yours.
Why, and what I do with it
Only what you asked for: to reply to your enquiry, to send Sentinel and the occasional update to members of my network, to answer your question, or to run the free build you entered. I don’t sell it, share it, or use it for advertising. A WhatsApp number is used once, to contact you about your enquiry.
Where it’s kept, and for how long
In a database on Cloudflare, which hosts this site. Enquiries, questions and free-build entries are kept for as long as we’re in touch and for up to two years after; network membership lasts until you leave.
Counting visits
This is a one-person site, and counting which pages people read, and where they came from, is how I learn what’s worth writing next. So the site counts its own visits. No ads, no selling, no third-party tools: my own code, on the same Cloudflare database as the forms, and nobody but me reads it. It never follows you anywhere else.
- What’s counted: each page you view, how long it was on screen and how far down you scrolled; where the visit came from (a search engine, an AI assistant, a social site, an email, a link with campaign tags, or another site, named by its address only, never the page); the page you arrived on; your country, as Cloudflare reports it; whether you’re on a phone, a tablet or a computer; and that a form was sent or Sentinel downloaded from a page, never what was in it.
- What’s never counted: your IP address, your browser’s identifying string, anything you type, or anything from any other site. There are no cookies.
- The anonymous id: in the UK, and outside the EU and EEA, the site keeps a random id in your browser’s local storage, so a second page, or a second visit, isn’t counted as someone new. It’s a random string, never tied to your name or email. UK law allows this for statistics that improve a site without asking first, as long as it’s explained (this section) and easy to refuse (the choice below).
- In the EU and EEA, or wherever your country can’t be told: the site asks first, with a small card. Until you say yes, pages are counted with no id at all and nothing is kept in your browser. If you say no, that stays so: pages are still counted with no id, and the only thing kept is your answer, so you aren’t asked again. To be left out of the count altogether, use the choice below.
- Global Privacy Control and Do Not Track: if your browser sends either, the site counts nothing from you and never asks.
- When you send a form: if your browser allows counting, the form also carries where you first arrived from (the campaign tags and the kind of site), so I know which of my posts start conversations. It’s kept with what you sent, and deleted with it.
- Tracked links: the QR code on my business card, and some links I share elsewhere, go through katosan.co.uk/c/…. Each visit through one records the time and the country only, then sends you on to the page.
- How long: the records are kept for 13 months, then folded into daily totals per page and source that can’t be traced to anyone. The id in your browser is let go after 13 months too.
You can change your mind here at any time, and it takes effect at once.
Your rights
You can ask to see what I hold about you, have it corrected, or have it deleted, at any time, by emailing me. You can also complain to the Information Commissioner’s Office (ico.org.uk).
