Privacy statement
In short
This site uses no analytics, no tracking and no contact form. It sets at most one cookie, and that cookie only remembers your language. While you read the pages, the hosting provider is the only company that receives data from your visit.
Who is responsible
Miguel Serrano Fuentes runs this website and is responsible for the data processing described here. For any question about your data, write to hello@miguelserrano.dev.
Hosting
Vercel Inc., USA, hosts this site. When you open a page, your browser sends technical data to Vercel: IP address, date and time, the address of the page, the address of the page you came from, and your browser and operating system (user agent). Vercel uses these data to deliver the site and to keep it secure.
In my Vercel account I can see a log of these requests for one hour. Vercel keeps its own records under its privacy policy.
The fonts, the map library and the map outlines come from this site’s own server. The pages load nothing from other providers.
Links to other websites, such as LinkedIn, open those websites. Their own privacy rules apply there.
If you write to hello@miguelserrano.dev, I use your email address and your message only to reply.
ImprovMX (ImprovMX Incorporated, USA) forwards the message to my Gmail mailbox. ImprovMX holds the message only until it is delivered, then deletes it. Its delivery log keeps your email address, the subject line and technical server data for 7 days, but not the message text.
Google (Google Ireland Limited) stores the message in my mailbox. I keep emails only as long as I need them to answer you and to follow up, then I delete them. Google says that removing deleted data from its systems takes about two months, and that its backups can keep data for up to six months.
Cookies and storage in your browser
The site stores these entries in your browser:
| Name | Type | Purpose | Kept for |
|---|---|---|---|
lang | Cookie | Opens miguelserrano.dev in the language you chose | 1 year |
lang | Local storage | Remembers the language you chose (backup for the cookie) | Until you delete it |
theme | Local storage | Remembers the colour theme you chose (light, dark or system) | Until you delete it |
msf-rules | Session storage | Plays the opening animation of the home page once per visit | Until you close the tab |
The site creates “lang” and “theme” only when you choose a language or a theme. The entries stay on your device. Your browser sends only the “lang” cookie, to Vercel with each request, so that miguelserrano.dev opens in your language. You can block or delete the entries in your browser settings. The site works without them.
Data abroad
Vercel can process these data in the USA and in other countries where it operates. Vercel Inc. is certified under the Swiss-U.S. Data Privacy Framework, which Switzerland recognises as providing adequate data protection.
Google Ireland Limited is in Ireland, which Switzerland recognises as providing adequate data protection. Google can also process data in other countries, including the USA. For this, it relies on the Swiss-U.S. Data Privacy Framework (Google LLC is certified) and on standard contractual clauses.
ImprovMX receives email in France, which Switzerland recognises as providing adequate data protection. ImprovMX is a US company and can deliver email through servers in the USA.
Your rights
You can ask what data I have about you, and you can ask me to correct or delete it. Write to hello@miguelserrano.dev. You can also complain to the Federal Data Protection and Information Commissioner (FDPIC) in Switzerland.
If the GDPR applies
This statement follows Swiss law. If the EU General Data Protection Regulation (GDPR) applies to your visit, these are the legal bases: for hosting, the legitimate interest in a working and secure website (Art. 6(1)(f) GDPR); for email, replying to your request (Art. 6(1)(b) or (f) GDPR). You can then also complain to the data protection authority in your EU country.
