Privacy Policy

1. Overview

At ZeroTools ("we", "us", or "our"), privacy is our core feature. This Privacy Policy explains what information is collected, how it is used, and how we ensure your data remains secure when you visit our website (zerotools.dev).

2. What We Collect (And What We Don't)

Tool Data (Zero Collection): Every utility on ZeroTools executes locally within your browser using JavaScript. When you paste JSON to format, upload an image to convert to Base64, or test a regular expression, that data is processed on your device's CPU. We do not transmit, log, or store your inputs or outputs.

Usage Data (Aggregated): We use Google Analytics to understand how visitors interact with our site. This collects anonymous, aggregated data such as:

• Pages visited and time spent on the site
• Browser type and operating system
• Referring URLs
• General geographic location (country/city level)

3. Cookies and Tracking Technologies

ZeroTools uses cookies to enhance your experience and support the free operation of the site. You can control cookie preferences through your browser settings.

• Local Storage: We use your browser's localStorage to save your UI preferences (like dark/light mode) and to temporarily cache the last input in a tool so you don't lose your work if you accidentally refresh the page. This data remains on your machine.
• Google Analytics Cookies: (e.g., _ga, _gid) Used to distinguish users and throttle request rates. These expire after a set duration (typically 2 years for _ga and 24 hours for _gid).
• Google AdSense Cookies: We use Google AdSense to display advertisements. Google uses cookies to serve ads based on your prior visits to our website or other websites on the internet.

4. Third-Party Services (Google AdSense Disclosure)

To keep ZeroTools free, we rely on advertising revenue. Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to your website or other websites.

• Google's use of advertising cookies enables it and its partners to serve ads to your users based on their visit to your sites and/or other sites on the Internet.
• Users may opt out of personalized advertising by visiting Ads Settings.

5. Children's Privacy

Our services are intended for developers and professionals. We do not knowingly collect personal information from children under the age of 13. If you are a parent or guardian and believe your child has provided us with personal information, please contact us.

6. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date at the top.
