1. Overview

ToolRunner.dev ("ToolRunner", "we", "us", or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard information when you visit our website at toolrunner.dev (the "Site").

2. Data Processing — Client-Side Only

All tools on ToolRunner process data entirely within your web browser using JavaScript and WebAssembly. No user-submitted data — including JSON, text, images, tokens, or any other input — is transmitted to, processed by, or stored on our servers. Your data never leaves your device.

3. Information We Collect

While we do not collect any data you process with our tools, we do collect limited analytics data to understand how the Site is used and to improve it:

Google Analytics (GA4): We use Google Analytics 4 to collect anonymized usage data such as page views, session duration, referral source, approximate geographic location (country/city level), browser type, and device type. Google Analytics may use cookies to distinguish unique users. This data is aggregated and does not personally identify you.
Local Storage: We use your browser's local storage to save your theme preference (light/dark mode). This data is stored only on your device and is never transmitted to any server.

4. Cookies

ToolRunner itself does not set any first-party cookies. However, third-party services integrated into the Site — such as Google Analytics and Google AdSense — may set cookies on your device to track usage and serve relevant advertisements. You can manage or disable cookies through your browser settings.

5. Google AdSense

We use Google AdSense to display advertisements. Google AdSense may use cookies and web beacons to serve ads based on your prior visits to this Site or other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your browsing history. You may opt out of personalized advertising by visiting Google Ads Settings.

6. Third-Party Services

We use the following third-party services:

Google Analytics 4 — for anonymized website usage analytics
Google AdSense — for displaying advertisements
Cloudflare / Vercel — for website hosting and content delivery

Each of these services has its own privacy policy. We encourage you to review their respective policies for more information on how they handle data.

7. Data Retention

Since we do not collect or store any user-processed data, there is nothing to retain or delete. Analytics data collected by Google Analytics is subject to Google's data retention policies.

8. Children's Privacy

ToolRunner is not directed to children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us so we can take appropriate action.

9. Your Rights

Depending on your jurisdiction, you may have rights regarding your personal data, including the right to access, correct, delete, or port your data. Since ToolRunner does not collect personal data beyond anonymized analytics, most of these rights are addressed by default. For analytics-related data, you can use Google's tools to manage your information.

10. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date. We encourage you to review this page periodically.
