Privacy Policy
In short: this website shows no advertising; I count visits without cookies. If you write to me through the form, your message is delivered to my mailbox, is used only to reply to you and is never sold.
1. Who I am
This website is run by Ivan Kuvshinov, an individual based in Portugal (“I”, “me”). I am the controller of the personal data described in this policy. For any privacy question write to ivan@kuvshinov.in.
2. Visiting the website
The website shows no advertising. Like any web server, my server processes the IP address, the time and the requested address of every visit to deliver the page, and keeps technical access logs for security and troubleshooting. Visits may pass through the network of Cloudflare (see “Where the data is stored”), which may set cookies strictly necessary to protect the website. If you choose a language on the website or open a link to a particular language version, the website remembers the language in a cookie named “lang” for one year; the cookie holds only the language code and is used only to show the website in that language.
Visit statistics. To learn how the website is used and to improve it, I count visits — on my own statistics server in the European Union and with Cloudflare. Statistics record the pages viewed, links followed and forms sent (not their content), the website you came from, technical information about your browser and device and an approximate location derived from your IP address. They use no cookies, are not used for advertising and are not shared with anyone else.
3. The contact form
If you write to me through the form, I receive what you send: your name, email address, the subject and the message. I use the IP address a message is sent from only to protect the form from abuse; it is not included in the message. The message is delivered to my mailbox by email; the website itself does not store it. I use all this only to reply to you. You are not required to give me your data, but without an email address I cannot reply.
4. Legal bases
Visit statistics, server logs, the delivery and protection of the website and the protection of the form rely on my legitimate interest in understanding how the website is used, improving it and keeping it working and secure. Replies to your messages rely on my legitimate interest in answering the messages you send me or, if your message is about working together, on steps taken at your request before entering into a contract. You can object by writing to me.
5. Where the data is stored and who receives it
- My servers. The website and the form run on servers I operate in the European Union, rented from a hosting provider that acts only as my processor. Messages from the form pass through my own mail server in the European Union.
- My mailbox is hosted by an email service provider in Switzerland that acts as my processor. The European Commission recognises Switzerland as providing an adequate level of data protection.
- Cloudflare. Visits may pass through the network of Cloudflare, Inc., which delivers and protects them and helps me count visits; it processes data on my behalf and, for the security of its network, under its own privacy policy. It may process data outside the European Union, including in the United States, relying on the EU–US Data Privacy Framework or the European Commission’s Standard Contractual Clauses.
- I do not sell personal data and do not share it with anyone else.
6. How long I keep data
- Visit statistics — up to 13 months.
- Server logs — up to 30 days.
- Messages you send me — for as long as needed to handle your message, and no longer than two years.
7. Your rights
If you are in the European Economic Area, the United Kingdom or another jurisdiction with similar laws, you have the right to access, correct or delete your personal data, to object to or restrict its processing and to data portability. To exercise these rights, write to ivan@kuvshinov.in; I reply within one month. You can also lodge a complaint with your data protection authority (in Portugal — the Comissão Nacional de Proteção de Dados, CNPD). I do not make decisions about you by automated means.
8. Security
Connections to the website are encrypted. Access to my servers is restricted to me.
9. Changes
If this policy changes, the new version will be published on this page with a new effective date.
