Terms of Service

Last updated: 28 April 2026

These Terms of Service ("Terms") govern your use of steblik.com (the "site"), operated by Miroslaw Steblik, a individual based in the United Kingdom ("we", "us", "operator"). By creating an account or otherwise using the site, you agree to these Terms. If you do not agree, do not use the site.

These Terms should be read together with the Privacy Policy and the Legal information page, which form part of the agreement between you and the operator.

1. About the site

The site is a personal technical blog and newsletter on data engineering, investment data infrastructure, and related topics. Some content is freely available; some content requires a free registered account. The site does not offer paid content, subscriptions, freelance services, consulting, or any other paid features. No commercial transactions take place through the site.

2. Eligibility

You must be at least 18 years old to create an account. By registering, you confirm that you meet this requirement and that the information you provide is accurate. The operator reserves the right to verify eligibility and to suspend or close accounts that do not comply.

3. Accounts

4. Acceptable use

You agree not to:

Security research conducted in good faith and disclosed responsibly is welcomed; please contact the operator before testing.

5. Intellectual property

Site content

All content published on the site — including articles, code samples, diagrams, graphics, and the underlying design — is the property of Miroslaw Steblik or the respective rights holders, and is protected by copyright and other intellectual property laws.

Unless explicitly stated otherwise on a specific piece of content, all rights are reserved. You may view and read content for personal, non-commercial purposes. You may share short quotations and links with proper attribution and a link back to the original page. Beyond this, you may not reproduce, republish, redistribute, or create derivative works from site content without prior written permission.

Code samples

Where a code sample is published with an explicit open-source license (for example, MIT or Apache 2.0), that license governs the use of that sample and overrides the general restrictions above.

Your feedback

If you send the operator suggestions, ideas, or feedback about the site, you grant a non-exclusive, royalty-free, worldwide, perpetual license to use that feedback for any purpose, without compensation or attribution.

6. No payments

The site does not currently offer paid content, subscriptions, or any other paid services. No payment information is collected or processed through the site.

If paid features are introduced in the future, additional terms — including pricing, billing, cancellation, and any rights under the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 — will be presented to you at the point of purchase, and you will need to agree to them separately before any charge is made.

7. Newsletter

The newsletter is sent only to users who have explicitly opted in. You can withdraw consent at any time using the unsubscribe link in any newsletter email or by emailing data@steblik.com. Withdrawing newsletter consent does not affect transactional emails necessary for the operation of your account.

8. No professional advice

Content on the site is published for general information and educational purposes only and reflects the personal views of the author. It is not, and must not be relied upon as, professional advice of any kind, including (without limitation) investment, financial, tax, accounting, or legal advice.

Although the author has worked on data infrastructure used by investment teams and holds educational qualifications relating to finance and investment operations, the author is not authorised by the Financial Conduct Authority (FCA) and does not carry on any regulated activity under the Financial Services and Markets Act 2000.

References on the site to financial markets, investment data, securities, fund performance, or trading systems are technical and architectural in nature. Nothing on the site constitutes a recommendation to buy, sell, or hold any financial instrument, or an inducement to engage in investment activity, and nothing on the site should be treated as a financial promotion.

You should obtain advice from an appropriately authorised professional before acting on any information on the site.

9. Third-party links and services

The site may link to or rely on third-party services (for example, email delivery providers). The operator is not responsible for the content, accuracy, or practices of any third party. Use of those services is governed by their own terms and policies.

10. Service availability

The site is provided on an "as is" and "as available" basis. The operator does not guarantee uninterrupted, error-free, or secure access, and may suspend or modify any part of the site at any time, with or without notice, including for maintenance, security, or operational reasons.

11. Suspension and termination

The operator may suspend or close any account that, in its reasonable view, has breached these Terms, presents a security risk, or is being used unlawfully. Where practical, you will be notified and given an opportunity to address the issue first; in serious cases, suspension may be immediate. On termination, your right to access the site ceases, and your data is handled in accordance with the Privacy Policy.

12. Disclaimers

To the fullest extent permitted by law, the operator disclaims all warranties, whether express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement, in respect of the site and its content.

Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any liability that cannot be excluded or limited under English law.

13. Limitation of liability

Subject to the paragraph above, the operator shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, revenue, data, business opportunity, or goodwill, arising out of or in connection with your use of the site, whether based in contract, tort, statute, or otherwise.

Where the site is used by a consumer, statutory rights under the Consumer Rights Act 2015 are not affected by these Terms.

14. Indemnity

Where you use the site for purposes related to a trade, business, craft, or profession, you agree to indemnify the operator against any claims, losses, costs, and expenses arising from your breach of these Terms or your unlawful use of the site. This clause does not apply to consumers acting outside the course of a business.

15. Changes to these Terms

These Terms may be updated from time to time. Material changes will be notified to registered users by email and will take effect no less than 14 days after notification, unless the change is required by law or relates to a new feature, in which case the change may take effect sooner. The "last updated" date above always reflects the current version. Continued use of the site after a change takes effect constitutes acceptance of the updated Terms.

16. Governing law and jurisdiction

These Terms are governed by the laws of England and Wales. Disputes shall be subject to the exclusive jurisdiction of the courts of England and Wales, except that consumers resident elsewhere in the United Kingdom retain the right to bring proceedings in their local courts.

17. Severability and entire agreement

If any provision of these Terms is held to be unenforceable, the remaining provisions remain in full force. These Terms, together with the Privacy Policy and the Legal information page, constitute the entire agreement between you and the operator regarding your use of the site.
