Last updated: October 19, 2026.

This notice explains what information is involved when you visit The SQL Booklet and how you can contact us about your personal data.

Information processed

The site is a public library and does not currently offer accounts, forms, purchases, or subscriptions. We do not ask for your name, phone number, payment details, or other personal information to browse the content.

When you access the site, the hosting provider and its content delivery network may process technical data such as your IP address, date and time, requested page, browser or device type, and security events. This information is used to deliver pages, keep the service available, prevent abuse, and troubleshoot failures.

Browser features

Your language preference is saved in your browser's local storage. Search downloads a public index and runs the query on your device; the text you enter is not sent to The SQL Booklet or to an external search service.

Providers and retention

The technical providers that host and protect the site are involved in delivering those services. The SQL Booklet does not currently load analytics or advertising services and does not sell personal data.

We do not maintain a visitor database. Technical logs generated by the infrastructure are retained and protected according to the provider's operational and security needs.

Contact and rights

You may request access, correction, deletion, or objection regarding your personal data by writing to privacidad@thesqlbooklet.com. Describe your request and provide a way to receive our response. If the information is held by a provider, we will direct you to the applicable channel.

We will update this notice when the data processed, its purposes, or the providers involved change. The date shown at the top identifies the current version.
