Privacy Policy
How personal data is handled when you visit this website or contact PORTA UNO. Last updated: 25 September 2026.
1. Responsible party
Yalcin Koyu Neißegasse 31 87600 Kaufbeuren Germany Email: yalcin@portauno.com Yalcin Koyu is the controller responsible for personal data processed through this website.
2. Website delivery and hosting
The website at https://portauno.com uses Next.js and is hosted by Vercel Inc., USA. The domain is registered through Namecheap. When you visit, technical request data such as your IP address, the requested URL, time of access, browser and device information, and referrer information may be processed to deliver the pages and protect the service. Vercel provides hosting and content delivery; authorised service providers may process data where needed to operate that infrastructure. The legal basis is Article 6(1)(f) GDPR: our legitimate interest in a secure, reliable website. Images, fonts and video are served with the website. There is no embedded third-party video player. You do not need to create an account or supply information through a web form.
3. International processing
Vercel operates internationally, so hosting data may be processed outside the EU/EEA, including in the United States. Vercel describes its processing arrangements and applicable transfer safeguards, including standard contractual clauses, in its data processing terms. Details: https://vercel.com/legal/dpa and https://vercel.com/legal/privacy-notice. You can contact us for further information about safeguards relating to your data.
4. Contact by email
Email links open your own email application. No message is sent until you choose to send it. If you contact us, we process your email address, name if supplied, message and attachments to respond and manage your enquiry. Our business mailbox, yalcin@portauno.com, uses Namecheap Private Email to send, receive and store correspondence. Provider information: https://www.namecheap.com/legal/general/privacy-policy/. The legal basis is Article 6(1)(b) GDPR for enquiries about a possible contract, or Article 6(1)(f) GDPR for other business correspondence. Please only include information needed for your enquiry.
5. Storage periods
We keep enquiry correspondence for as long as it is needed to respond and, where relevant, manage a business relationship. We delete data when it is no longer needed, unless legal retention obligations or the establishment, exercise or defence of legal claims require further storage. Technical hosting data is retained according to the hosting service’s operational and security requirements; this website does not maintain a separate visitor database.
6. Cookies, analytics and local storage
The website does not use visitor analytics, advertising pixels, marketing cookies or persistent browser storage for tracking. Language is selected through the URL. Movement choices stay in page memory and are not saved as a visitor profile. On the English homepage, browser language is checked locally to offer a temporary Chinese-language hint; this does not redirect visitors or create persistent storage. Hosting infrastructure may process technical information necessary for delivery and security. No consent-based tracking service is integrated, so no tracking-consent banner is displayed.
7. LinkedIn and external links
LinkedIn is linked as an external website, not embedded as a widget. Simply loading our pages does not load LinkedIn content. If you follow the link, LinkedIn receives your request and processes data under its own policy: https://www.linkedin.com/legal/privacy-policy. Other external websites also apply their own privacy policies.
8. Your rights
Subject to the GDPR’s conditions, you may request access, rectification, erasure, restriction of processing and data portability. Where processing is based on legitimate interests, you may object on grounds relating to your particular situation. If processing relies on consent, you may withdraw it at any time without affecting the lawfulness of earlier processing. To exercise your rights, contact yalcin@portauno.com. You may lodge a complaint with a supervisory authority, particularly in the EU country where you live, work or believe an infringement occurred. Our local authority is the Bavarian State Office for Data Protection Supervision (BayLDA): https://www.lda.bayern.de/de/beschwerde.html.
9. Voluntary contact and automated decisions
Providing information by email is voluntary, although we need sufficient contact details to respond. We do not use your website visit or enquiry for automated decisions producing legal or similarly significant effects, or for profiling.
