Privacy Policy

This Privacy Policy explains, in plain language, how this website handles your personal information. It is written for visitors, not for engineers, and avoids technical jargon wherever possible. Our goal is to be clear and honest about what happens to your information when you use the site.

1. Who we are

This website is operated by Aleksandr Filippov as the data controller. If you have any questions about this Privacy Policy or about how your information is handled, please get in touch via our contact form.

2. What information we collect

We only collect information that you choose to provide, or that we need to keep the site running. The categories are:

  • Information you give us through the contact form — your name, your email address, and the message you write to us.
  • Information about how visitors use the site (in aggregate) — for example, which pages are popular and roughly where in the world visits come from. This is collected only after you have agreed in regions where consent is required.
  • Limited technical information needed to keep the site secure and reliable — for example, anti-spam checks on the contact form so that automated submissions can be filtered out.

We do not collect special category data (such as health, biometric, or political opinions), and we do not buy personal information from third parties.

3. Why we collect it

We use your personal information for clearly defined purposes:

  • To reply to you when you write to us through the contact form.
  • To understand, in aggregate, how the site is used so we can improve it (which articles people read, which pages are slow, and so on).
  • To keep the site secure, for example by stopping automated spam submissions to the contact form.

We do not use your information for advertising, profiling, or any kind of automated decision-making about you.

We rely on the following legal bases under UK GDPR / EU GDPR:

  • Performance of a service you have asked for — when you send a message through the contact form, we process your name, email and message so we can read and reply to it.
  • Your consent — in regions where the law requires prior consent (the EU/EEA, the United Kingdom, Switzerland, and the EFTA non-EU EEA states Norway, Iceland and Liechtenstein), we only enable analytics after you click Accept on the consent banner. You can withdraw your consent at any time (see Section 9 below).
  • Our legitimate interests — we run anti-spam checks on the contact form to protect the site and our ability to respond to genuine messages. We have considered visitors’ interests and rights and concluded that this minimal, transparent processing does not override them.

5. Cookies and similar technologies

We group cookies and similar storage technologies by purpose, not by technical name:

  • Strictly necessary — these are always active, because the site cannot work properly without them. They include things like remembering your consent choice, supporting offline browsing, remembering your light/dark theme preference, and running the anti-spam check on the contact form. No consent is required for these.
  • Analytics — these help us understand how visitors use the site in aggregate. In regions that require prior consent, these are loaded only after you accept on the consent banner. In other regions, they may be loaded automatically, and you can opt out at any time using the Cookie settings link in the footer.

You can also control or delete cookies via your browser’s own settings:

Please note that blocking strictly-necessary cookies may break the contact form, offline support, or your theme preference.

6. Who we share information with

We share personal information only with the following categories of recipients, and only to the extent needed for the purposes above:

  • Our hosting and security provider — we host the site with a global content-delivery and security provider that also helps us deliver the consent banner and run the anti-spam check on the contact form.
  • Our analytics provider — we use a third-party analytics service to understand site usage in aggregate. It is loaded only with your consent in regions that require it.

We do not sell your personal information, and we do not share it for advertising purposes.

7. How long we keep information

We keep personal information only for as long as we need it for the purpose for which it was collected:

  • Messages sent through the contact form are kept for as long as is reasonably needed to deal with your enquiry and any follow-up, after which they are deleted.
  • Analytics information is kept only for the period set by our analytics provider’s default retention settings, after which it is automatically deleted.
  • Your consent record is kept on your device so that we do not show you the consent banner repeatedly. You can clear it at any time via the Cookie settings link in the footer or by clearing site data in your browser.

8. Your rights

Under UK GDPR / EU GDPR, you have the following rights in relation to your personal information:

  • The right to be informed about how we use your information (this Privacy Policy).
  • The right of access — you can ask for a copy of the personal information we hold about you.
  • The right to rectification — you can ask us to correct information that is inaccurate or incomplete.
  • The right to erasure — you can ask us to delete personal information in certain circumstances.
  • The right to restrict processing — you can ask us to stop using your information in certain circumstances.
  • The right to data portability — you can ask us to give you a copy of certain information in a portable format.
  • The right to object — you can object to processing based on our legitimate interests.
  • The right to withdraw consent — where we rely on your consent, you can withdraw it at any time.
  • The right to lodge a complaint with a supervisory authority. In the United Kingdom this is the Information Commissioner’s Office (ICO); in the EU/EEA it is the data protection authority of your country of residence.

Exercising these rights is free. We will respond within the time limits required by law.

9. How to exercise your rights

To exercise any of the rights above, please contact us using the contact form. We may need to ask you for information to confirm your identity before we act on your request, so we are sure we are communicating with the right person.

To withdraw consent for analytics, click the Cookie settings link in the footer at any time, change your choice, and save. Withdrawing consent is as easy as giving it.

10. International transfers

Our hosting / security provider and our analytics provider operate from the United States. When your personal information is transferred outside your country, we rely on safeguards recognised by UK GDPR and EU GDPR — typically standard contractual clauses or an equivalent legal mechanism — so that your information continues to receive an essentially equivalent level of protection.

11. Automated decision-making

We do not use automated decision-making, profiling, or other automated processing that produces legal or similarly significant effects for you.

12. Children

This site is not directed at children, and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us and we will take steps to remove it.

13. Changes to this policy

If we make material changes to this Privacy Policy, we will update the page and change the Last updated date below. Please check this page from time to time. Material changes will not be applied retroactively to information we have already collected.

14. Contact us
