This page explains what data go-tutorial.com collects when you visit, why, and what you can do about it. The short version: there are no accounts, no comments and no newsletter here, so I don’t ask for your name or email. The site uses privacy-friendly analytics, and it shows ads from Google AdSense, which uses cookies.
Who runs this site
Go Tutorial (go-tutorial.com) is written and run by Erik van Baaren (The Dutch Dev), who also runs Python Land. I’m responsible for the data described on this page. You can reach me through the contact page.
Server and security logs
Like every website, the web server and the content delivery network in front of it (Cloudflare) process technical data to deliver pages and protect the site against abuse: your IP address, the page you request, your browser’s user agent and the time of the request. This data is used only to run and secure the site and is kept for a limited time.
Analytics
I use Matomo to see which lessons people read, so I know what to improve and what to write next. Matomo is self-hosted on my own server, and the tracking requests go through go-tutorial.com itself. The data isn’t shared with or sold to anyone. Matomo uses first-party cookies to recognize returning visitors.
Advertising (Google AdSense)
Go Tutorial is free, and ads help pay for it. Ads on this site are served by Google AdSense.
- Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.
- Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet.
- You can opt out of personalized advertising by visiting Google’s Ads Settings. You can also opt out of some third-party vendors’ use of cookies for personalized advertising at www.aboutads.info or, in Europe, www.youronlinechoices.eu.
Google explains how it uses information from sites that show its ads in How Google uses information from sites or apps that use our services.
If you visit from the European Economic Area, the United Kingdom or Switzerland, you’ll be asked for consent before personalized ads or advertising cookies are used. You can change your choice at any time with the privacy settings link that appears at the bottom of the page once you’ve made a choice.
Fonts and embedded content
The fonts on this site are served from go-tutorial.com itself, so loading a page doesn’t contact Google Fonts or another font service. Lessons link to external sites such as go.dev and pkg.go.dev; those sites have their own privacy policies once you click through.
Your rights
Depending on where you live, for example in the EU under the GDPR, you have the right to ask what personal data I hold about you, to have it corrected or deleted, to object to its processing, and to file a complaint with your data protection authority. Because the site has no accounts or forms, I usually hold no data that identifies you directly. If you have a question or request, use the contact page.
You can also block or delete cookies in your browser settings. The site works without them, but ads may become less relevant.
Changes to this policy
If I change how the site handles data, I’ll update this page and the date at the top.
