This notice covers arwell.works only. Eolin, at eolin.app, has its own privacy information.
When you visit this site
The site has no accounts, forms, analytics or advertising, and sets no tracking cookies. To deliver the pages and keep them secure, our hosting provider’s servers process technical data: your IP address, browser and device type, the page requested and the time.
If our security system suspects automated traffic, it may show a short check and set a technically necessary cookie to remember that you passed it.
- Purpose: running the website and protecting it from abuse.
- Legal basis: our legitimate interest, Art. 6(1)(f) GDPR.
- Retention: in short-term server logs only, deleted automatically within 30 days.
When you email us
If you write to an @arwell.works address, we use your name, email address and message to reply and to keep a record of the conversation.
- Legal basis: our legitimate interest in answering you, Art. 6(1)(f) GDPR, or steps you ask for before a contract, Art. 6(1)(b).
- Retention: for as long as the conversation and any follow-up need it, and no longer than three years after our last contact, unless the law requires us to keep it longer.
Fonts and links
Fonts and images are served from this site, so no third party receives your data when a page loads. Links to LinkedIn and eolin.app send data to those sites only if you follow them.
Who processes data for us
- Vercel Inc., USA: hosting and security.
- Microsoft: email, through Microsoft 365.
Where data goes to the United States, the transfer relies on the EU–US Data Privacy Framework or the European Commission’s standard contractual clauses.

You can ask us for access to your data, to correct or delete it, to restrict how we use it, to object to its use, or to receive it in a portable format. Write to hello@arwell.works. We reply within one month.
You can also complain to the Czech data protection authority: Úřad pro ochranu osobních údajů, Pplk. Sochora 27, 170 00 Praha 7, uoou.gov.cz.
