Who is responsible

Mikhail Savchenko (Mike Fluff) operates this site. For anything on this page, write to [email protected].

What you hand over on purpose

Four forms ask for data: the contact form, the course enrolment form, the Architect Mode application and the newsletter field on the Skills page. Between them they collect a name, an email address, an optional subject and whatever you type into the message field.

Each submission is stored in a database on a server rented for this site, and a copy is emailed to the address above through Mailgun. The row is the record; the email is only a notification.

The chat assistant stores the conversation and, if you give one, an email address. It also stores facts you state about your business — company size, the problem you describe, your timeline — so it does not ask twice.

What is collected without you typing it

Your IP address is hashed with SHA-256 and truncated before it is stored. The original is never written down. It exists to rate-limit the chat and the forms, nothing else.

Your browser keeps a language cookie, your chat history and a reader number in local storage. Those never leave your device and are never sent anywhere.

If page analytics is enabled it is self-hosted, records page views and button clicks without cookies, and does not build a profile across sites.

Analytics and ad measurement

Google Analytics 4 counts visits and what happens on the site: pages viewed, chapters opened and finished, experiments started, checkouts started, purchases and requests sent. It sets cookies and receives your IP address and browser details. If you are signed in it gets an opaque identifier derived from your account, never the account itself.

The Meta pixel and Meta’s Conversions API record the same actions so that ads on Facebook and Instagram can be measured: whether someone who saw an ad later read a chapter, bought a book or booked a call. The copy sent from the server carries your IP address, browser details and, if you gave it (signing in, a form, a purchase), a SHA-256 hash of your email, never the email itself.

In the European Economic Area, the United Kingdom and Switzerland both run only after you press Allow on the cookie bar. Elsewhere they run from the first page and the bar offers to switch them off. The choice is kept in your browser; clear this site’s data and the bar will ask again.

Google and Meta process this data under their own policies.

Who else sees it

Mailgun delivers the notification emails. Calendly handles booking, and what you enter there is held by Calendly under its own policy. Anthropic processes chat messages to generate replies. The database and the site run on a rented server.

Signing in goes through INITE (auth.inite.ai), and payments for books and courses through INITE billing and the payment provider it hands you to.

Nothing is sold or rented. Google and Meta receive the measurement data described in the section above; no other advertising network runs on this site.

How long it is kept

Leads and conversations are kept while they are useful for the work they started, and deleted on request. Rate-limit records expire within a day.

What you can ask for

Email [email protected] to get a copy of what is held about you, to correct it, or to have it deleted. Say which address you used and it will be found.
