Privacy Policy

Introduction

At SQL Playground, we prioritize your privacy. This policy explains how we handle your information when you use our website. The short version is: we do not collect your personal data.

Local Processing

SQL Playground is a client-side application. This means:

• All SQL queries are executed locally in your browser using WebAssembly.
• Any CSV files you upload are processed strictly within your browser memory.
• Your data is never sent to our servers or any third party.

Data Collection

We do not track your personal information. We do not use cookies for tracking or advertising purposes.

We may use local storage (localStorage) on your device to save your preferences, such as:

• Theme settings (Light/Dark mode).
• Tutorial progress.
• Editor configuration.

This data stays on your device and is not accessible to us.

Hosting & Analytics

This website is hosted on Vercel/Cloudflare. These platforms may collect anonymous technical logs (IP address, user agent) for security and performance monitoring purposes. Please refer to their respective privacy policies for more details.
