Privacy Policy

Last updated: 8 October 2026

Article 50 Guard (vprokhorov.com) checks whether websites tell visitors that a chat is run by an AI, as the EU AI Act (Article 50) asks. This page explains, in plain words, what personal data we handle and why.

2. What data we handle

The free check form. The website address you type in and, if you choose to give it, your e-mail address (so we can send you the PDF report). The e-mail is optional.
Public information from the websites we check. We open the public pages of a website, look for a chat widget, record the text the widget shows and take a screenshot of it. We do not log in anywhere and we do not read private areas. If a screenshot or text happens to include a person's name, it is only what the website itself shows to every visitor.
Business contact details. To tell a website owner about the result of a check, we use the business e-mail address that the website publishes for contacting the company.
Messages you send us. If you write to us or reply to a message, we keep the correspondence.
Visit statistics. This site uses Google Analytics to count visits and clicks (pages viewed, approximate region, device type). It uses cookies for this. You can block them in your browser settings.

3. Why, and on what basis

To run the check you asked for and send you the report — performing your request.
To write once to a business whose public chat does or does not tell visitors it is an AI — our legitimate interest in offering a related service (Article 6(1)(f) GDPR). It is a short message to a business address, not a mailing list. If you do not want to hear from us again, reply "stop" and we will not write to you again.
To understand how the site is used — our legitimate interest, and your consent where the law requires it for cookies.

4. Google account data

Article 50 Guard uses a Google application (OAuth) that is operated by us for our own account only. It is not offered to the public, and nobody else signs in to it. The application never receives data of other Google users.

With the owner's permission, the application uses these Google services in the owner's own account:

Google Drive — to store the PDF reports and screenshots of the checks in our own folders.
Google Sheets — to keep our own table of checked websites and their results.
Gmail (create drafts) — to put prepared messages into our own Drafts folder. The application does not read our e-mails, and it does not send anything by itself: every message is read and sent by a person.

We do not sell this data, do not share it with third parties, do not use it for advertising, and do not use it to train artificial-intelligence or machine-learning models. Only the account owner can see it.

The use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

6. How long we keep it

Check results, screenshots and reports — up to 24 months, then deleted.
E-mail addresses from the form — until you ask us to delete them, but no longer than 24 months without contact.
Correspondence — while it is useful for the business, up to 3 years.
Analytics data — as set in our Google Analytics settings.

7. Your rights

You can ask us to show you your data, correct it, delete it, limit its use, or send it to you. You can object to our messages at any time. Write to vladimir@vprokhorov.com — we answer within one month. You may also complain to the data protection authority in your country; in Bulgaria this is the Commission for Personal Data Protection (cpdp.bg).

8. Changes

If this policy changes, the new version is posted on this page with a new date.

This page describes our practice in plain terms and is not legal advice.
