1. Introduction

Welcome to Fast Toolkit ("we", "our", or "us"). We operate fasttoolkit.dev and are committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our online developer tools.

2. Information We Do NOT Collect

Our tools—including JSON and XML formatters, YAML/JSON conversion, CSV utilities, Markdown preview, QR generation, timestamp conversion, Base64 (text and image), URL encoding, regular-expression testing, HTML entity helpers, UUID generation, number-base conversion, and the color picker—run entirely in your browser. We do not collect, store, or transmit the payloads you paste, upload locally, or generate. Your content does not leave your device to our application servers as part of those tool operations.

You are still responsible for compliance with your employer’s policies, clearing shared workstations after sensitive work, and avoiding pasting regulated data into any third-party website when prohibited.
