Privacy policy
This site uses no cookies and loads nothing from third parties. This page explains what data reaches the server when you visit, what it is used for and how long it is kept.

What data is processed
Server logs
Like any web server, the one behind thinkingdata.info records each request: the IP address, date and time, the page requested (including URL parameters, such as those added by ads), the page you came from and your browser. The logs keep the site running and protect it against attacks. They are kept for about five weeks and then deleted automatically.
Visit statistics
To count visits I use Matomo, installed on my own server (stats.thinkingdata.info). It is set up to:
- use no cookies and store no identifier in your browser;
- shorten your IP address (the last two blocks are removed) before storing it;
- respect your browser’s Do Not Track setting;
- delete the data of each visit after 90 days, keeping only aggregate reports, such as how many visits a page has had.
This data is not shared with anyone.
If you write to me, I will use your address and what you tell me only to reply and, if we work together, for our professional relationship. I keep emails for as long as that relationship requires and to meet legal obligations, such as tax rules.
Legal basis
- Logs and statistics: legitimate interest in keeping the site secure and knowing how it is used, with data kept to a minimum (Article 6(1)(f) GDPR).
- Email: your request and, where relevant, pre-contractual steps or the contract (Article 6(1)(b) GDPR).
Cookies and browser storage
This site uses no cookies. The only thing stored in your browser is your language preference: if you pick a language with the switcher or dismiss the notice suggesting another one, your browser remembers it (local storage) so the notice does not show again. This information never leaves your device, and you can delete it at any time in your browser settings.
Who else is involved
- Hosting: the server is provided by Hetzner Online GmbH in Germany, acting as data processor. Data does not leave the European Union.
- External resources: none. Fonts and all other files are served from the same server; the site loads nothing from Google or any other service.
- Ads: if you arrive from an ad, the URL may carry an identifier added by the ad service (for example, Google’s
gclid). It ends up in the server logs like the rest of the URL, but this site sends no data to the advertiser. - Other sites: linked sites (Terrindus, Turn One Data, Matriscar and others) have their own policies.
Your rights
You can ask to access, correct or erase your data, object to or restrict its processing, or request its portability by writing to ivan@thinkingdata.info. Because the statistics identify no one, I may not be able to find your data in them.
If you think your rights have not been respected, you can lodge a complaint with the Spanish Data Protection Agency (AEPD).
No automated decisions or profiling take place.
Changes
If the way data is handled changes (for example, if an external tool is added), this page will be updated first.
