This page explains what personal data this website collects and how it is used. It is kept short because we collect very little.
This website is run by Hayakawa Kowalczyk, 7-9-503 Yotsuya-honshiocho, Shinjuku, Tokyo 160-0003, Japan. For any question about your data, write to info@hayakawakowalczyk.com.
With your permission, we use Google Analytics to see how many people visit the site and which pages they look at. This helps us understand interest in our work. Google Analytics sets cookies in your browser and sends information such as the pages you visit, your approximate location, and your device and browser type to Google, which may process it outside Japan and the EU, including in the United States. We do not use this information to identify you, and we do not use advertising features.
Google Analytics only runs if you choose “I am ok with that” in the cookie banner. If you choose “Disable Analytics”, or make no choice, no analytics cookies are set. Your choice is stored in a small cookie (cookie_consent) for 30 days. You can change it at any time with the buttons below.
If you write to us, we use your name, email address and message only to reply and to handle your enquiry. We do not share them for marketing.
Like any website, our server keeps short-term technical logs (such as IP address, date and page requested) to keep the site secure and working. These are not used for any other purpose.
You can ask us what personal data we hold about you, and ask us to correct or delete it, by writing to the address above. You also have the right to complain to your local data protection authority.
