Egyéni vállalkozó — the Hungarian form shown above — is a registered sole trader: an individual who trades under their own name and is personally liable, entered in a public national register. There is no company registration number, because there is no company; the registration number above is the equivalent identifier.
The primary contact channel is email. A phone number is deliberately not published here: for this kind of work written exchanges are more precise, and scheduled calls are arranged by email in any case. Clients do get my phone number — with ongoing maintenance that is part of the job.
The activity is not subject to licensing and is not a regulated profession, so no authorisation details apply. I am not bound by any code of conduct.
2. Hosting provider

- Company registration number
- 01-09-909968
- Tax number
- 14571332-2-42
- Website
- tarhely.eu
3. What this website does
This section is not a legal requirement but a companion to the details above. An imprint says who runs the site; these few lines say what the site does while you are reading it.
- It sets no cookies and writes nothing into your browser's storage. Details in the cookie notice.
- It runs no analytics, measures no traffic, and carries no tracking code.
- It loads no external resources: fonts, images, styles and scripts all come from this domain, so your browser never contacts another provider.
- There is no form on it. Contact happens by email, from your own mail client.
- There is no embedded content — no maps, no videos, no social media widgets.
What the server records regardless — IP address, timestamp, requested path — is what every web server records; how that is handled is described in the privacy notice.
4. Copyright and the names that appear
The texts, case studies, diagrams and code excerpts on this site are, unless marked otherwise, the provider's own work. Quoting with attribution and a link is welcome; reproducing whole texts requires prior permission.
Company and brand names mentioned in the case studies belong to their respective owners and serve only to identify the work carried out. A mention does not imply a partnership or endorsement beyond what the case study itself describes.
5. Accuracy of the content
The case studies and technical writing are based on real, measured data at the time of writing. The technical environment changes: a plugin's behaviour, a service's pricing or an interface's layout can all shift after publication. The “Updated” date on each page shows when I last went through it.
The content is informational and does not constitute legal, tax or financial advice.
6. Consumer disputes
The great majority of my clients are businesses. Where a client does qualify as a consumer, complaints can be raised with me first at the email address above — I record and answer complaints in writing.
If that does not resolve the matter, a consumer may turn to the conciliation board (békéltető testület) competent for their place of residence or for the provider's registered address. These are free, out-of-court bodies attached to the Hungarian chambers of commerce. The board competent for my address:
- Name
- Budapest Conciliation Board (Budapesti Békéltető Testület)
- Address
- Krisztina körút 99, 1st floor 111, 1016 Budapest, Hungary
- Postal address
- 1253 Budapest, Pf. 10, Hungary
- bekelteto.testulet@bkik.hu
Consumer protection complaints may also be submitted to the competent Budapest or county government office.
7. Updating this imprint
This page changes when any of the details above change — the registered address, the hosting provider, or what the site does. Section 3 is deliberately written as verifiable claims: if analytics or embedded content is ever added, that section and the cookie notice change first, and only then the code.
