3. Hosting and server log files
This website is hosted by dhosting.pl Sp. z o.o., ul. Pamiętna 14B/2, 02-972 Warsaw, Poland. When you visit the website, the server automatically processes information sent by your browser: IP address, date and time of access, page requested, referrer URL, browser type and operating system. This is necessary to deliver the website and keep it secure and stable (Art. 6(1)(f) GDPR). Log files are kept only as long as needed for these purposes.
4. SSL/TLS encryption
This website uses SSL/TLS encryption. You can recognise an encrypted connection by “https://” and the padlock icon in your browser’s address bar.
5. Contact form, e-mail and phone
When you contact us via the contact form, by e-mail or by phone, we process the details you provide (e.g. name, e-mail address, phone number and the content of your message) to handle your enquiry and prepare a quote. The legal basis is Art. 6(1)(b) GDPR where your enquiry relates to concluding a contract, otherwise Art. 6(1)(f) GDPR (our interest in answering enquiries). Form data is sent to us by e-mail via the mail server of an e-mail service provider in Poland. We delete your data once your enquiry has been fully dealt with, unless statutory retention obligations (in particular under commercial and tax law) apply.
6. Cookies
This website uses only technically necessary cookies, for example to remember the language you selected. They are required for the website to work and are set on the basis of the national rules implementing Art. 5(3) of the ePrivacy Directive and Art. 6(1)(f) GDPR. We do not currently use analytics or marketing cookies. You can delete or block cookies in your browser at any time.
7. Google Tag Manager
We use Google Tag Manager provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Tag Manager is used to manage scripts on the website and does not set cookies itself. When it loads, however, your IP address is transmitted to Google, and a transfer to the USA cannot be ruled out. Google LLC is certified under the EU-US Data Privacy Framework. No analytics or marketing services are currently delivered via Tag Manager. The legal basis is Art. 6(1)(f) GDPR. If we use analytics or marketing services in the future, we will ask for your consent first and update this policy.
8. Google Fonts
To display fonts consistently, this website uses Google Fonts provided by Google Ireland Limited. When you open a page, your browser loads the required fonts from Google’s servers, which transmits your IP address to Google. A transfer to the USA cannot be ruled out (Google LLC is certified under the EU-US Data Privacy Framework). The legal basis is Art. 6(1)(f) GDPR (consistent and appealing presentation of the website).
9. Links to social networks
We link to our Facebook page. These are simple links: no data is transferred until you click the link and open the page of Meta Platforms Ireland Limited, where Meta’s privacy policy applies.
10. Your rights
You have the right of access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18) and data portability (Art. 20), and the right to object to processing based on Art. 6(1)(f) GDPR (Art. 21). You can withdraw any consent you have given at any time with effect for the future (Art. 7(3) GDPR). To exercise your rights, write to info@aristofenster.eu.

You may lodge a complaint with a data protection supervisory authority, in particular in the Member State of your habitual residence, place of work or the place of the alleged infringement.
