Subscription and data

This page describes the actual data path for the AI Does the Work. People Own the Outcome. digest.

Legal review date: 2026-08-11. This is the public policy and consent text for this form. It is not personal legal advice.

Wherever you live, this page applies to you, because it describes what this site does with the address you type in. The legal references below are Russian: the operator is based in Russia, so Russian personal data law is what binds him. They are his obligations, not a statement about your rights at home. Whatever your own country grants you applies on top of what is described here.

Who processes the data

The data operator is Denis Ermilov, the author of this project. To ask about your data, correct an address, or withdraw consent, use the contact details on the About the project page.

What the subscription record contains

The record contains:

  • your email address;
  • the issue language, RU or EN;
  • a technical identifier for the page where you submitted the form;
  • the date and time of subscription;
  • confirmation of both consents and the version of the consent text.

We do not ask for your name, phone number, or identity documents. The subscription record does not contain your raw IP address or an IP hash. Hosting systems may process standard network logs for security and reliability. Those logs are not part of the mailing list and are not used to send email.

We use the data only to manage the subscription and send digest issues, usually one email a week. The legal basis for processing the address is your separate consent. A second required checkbox records your agreement to receive email. The form rejects the address unless you give both consents.

We do not sell the address, add it to another mailing list, or send it to advertising platforms.

What happens after you submit the form

The site receives the form on a Vercel server and sends the record over a secure connection to the separate digest backend on HostKey infrastructure. The persistent subscriber list stays in that backend under the author's control. Vercel Web Analytics does not receive the email address, form values, or subscriber list.

The system performs only the operations needed for the subscription: collection, recording, organization, storage, correction, retrieval for delivery, blocking, and deletion.

Retention and deletion

We keep the address while the subscription is active. Unsubscribing stops delivery and removes the address and its subscription events from the working log. The service does this immediately after a valid unsubscribe request. If you withdraw consent by contacting the author, the request will be handled without undue delay and within the time limits in Russian personal data law.

Every sent issue must include an unsubscribe link. Email delivery has not launched yet, so you can withdraw consent through the contact details on the About the project page.

Records created before consent version 2026-08-11 are not treated as if they had accepted the new terms. They are excluded from the active delivery list until the operator either obtains fresh consent or deletes the legacy record.

Web analytics

The Practicum collects anonymised statistics about page visits and actions. It exists so we can see which materials people read and which are missing. Analytics is never a source of product data: search, pages and the subscription work the same way even when the analytics script is blocked by the browser.

Two tools are used: Vercel Web Analytics and PostHog. The analytics request leaves from the Practicum's own domain. Scripts load only after the page has fully opened and take no part in rendering it.

What is collected:

  • page address, page language and referrer;
  • country, device type, browser and operating system in aggregated form;
  • the fact of an action on the page: copying a prompt, downloading a material, a search query, switching language, following an external link, scrolling to the end of a page;
  • for the subscription form, only the fact of submission and its result.

What is not collected:

  • email address, form field values or the subscriber list;
  • the content of pages you read or fill in on your side;
  • screen recordings or cursor movement.

Event properties are limited to a predefined list on the site's side, so an address or form content cannot reach analytics technically, not merely by agreement.

Nothing is stored in your browser: analytics works without cookies and without writing to browser storage, and a visitor is not recognised between visits. If your browser sends a Do Not Track signal, analytics does not start at all.

How to turn it off

The choice is stored in your browser and applies across the Practicum. Press the same button again to turn analytics back on.

Your rights

You can ask what data is processed, correct the address, withdraw consent, ask us to stop processing, or request deletion. Include the email address you used so that we can find the right record.

By selecting the first checkbox and submitting the form, you freely and clearly agree that Denis Ermilov may process the data listed above to manage your subscription and send the digest. The consent covers the listed operations. It lasts until you unsubscribe or withdraw it. You can withdraw it through the link in an email or by contacting the author.

The second checkbox separately records your agreement to receive issues by email. The consent text used by the form is version 2026-08-11.

This page closes the review of the public wording and its match with the implemented data flow. It does not by itself prove that the operator has completed external administrative steps, including a Roskomnadzor notification or the Russian database localization requirement. The operator must check those duties separately against the storage location and any applicable exception.
