Privacy Policy

Last updated: May 2026

The short version

ToolNinja runs entirely in your browser. We collect zero personal data, zero usage data, and make zero server calls when you use any tool. There is nothing to sell and nothing to leak.

1. What we collect

Nothing. Every tool on ToolNinja executes its logic locally in your browser using JavaScript. Your code, text, keys, tokens, passwords, or any other input you paste into a tool never leave your device. No data is transmitted to any server.

2. Cookies and local storage

ToolNinja does not use tracking cookies or persistent identifiers. Some tools may store preferences (such as selected options or tab state) in your browser's local storage for convenience within that browser session. This data is stored only on your device and is never transmitted anywhere.

3. Analytics

We do not use Google Analytics, Mixpanel, Segment, or any third-party analytics service that tracks individual users. We may use aggregated, anonymous server access logs (e.g. page views by URL, not by user) to understand which tools are popular. These logs contain no personally identifiable information.

4. Third-party services

ToolNinja is hosted on infrastructure that may collect standard web server logs (IP address, user agent, timestamp, URL). This data is handled according to the hosting provider's own privacy policy and is not combined with any user-level data by us. We do not integrate any advertising networks, social tracking pixels, or user profiling services.

5. Security tools

Tools such as AES encryption, RSA key generation, and JWT signing use your browser's built-in Web Crypto API. Keys and plaintext are never sent to any server. You should still take care not to paste production secrets into any browser-based tool, including this one, if your threat model requires it.

6. Children's privacy

ToolNinja does not knowingly collect any information from children under 13. Because we collect no personal information at all, there is nothing to address specifically for minors.

7. Changes to this policy

If this policy changes materially, we will update the "Last updated" date at the top of this page. Continued use of ToolNinja after a policy update constitutes acceptance of the revised terms.
