Privacy Policy

Last updated: March 2026

Short version: API Dev Utils processes all data entirely in your browser. We don't collect, store, or transmit the content you enter into any tool. No accounts, no tracking, no ads.

1. Information We Collect

API Dev Utils is a client-side application. All tools run entirely in your browser using JavaScript. The data you input into any tool — JSON, URLs, tokens, passwords, text — is never sent to our servers and is never stored by us.

We collect the following minimal information:

  • Browser local storage: We store a list of recently used tools in your browser's localStorage. This data never leaves your device and contains only tool names and URLs, not any content you've entered.
  • Theme preference: Your light/dark theme setting is saved in localStorage. Again, this never leaves your device.
  • Server access logs: Our hosting provider may automatically log standard HTTP request metadata (IP address, browser type, referrer, timestamp) for security and operational purposes. We do not use these logs for tracking or profiling.

2. How We Use Information

Since we collect almost nothing, our use is correspondingly minimal:

  • Locally-stored preferences are used solely to improve your experience (remembering your theme, showing recently used tools).
  • Server access logs may be used to diagnose technical problems and protect against abuse.
  • We do not sell, share, or otherwise disclose any data to third parties.

3. Cookies

API Dev Utils does not set any cookies. User preferences are stored in browser localStorage, which is not transmitted with HTTP requests and is not accessible to third parties.

4. Third-Party Services

We use the following third-party services that may process limited data:

  • Google Fonts: We load fonts from Google Fonts, which may result in your browser making a request to Google's servers. See Google's Privacy Policy for details. You can alternatively self-host fonts by modifying your browser settings to block third-party font requests.
  • Hosting provider: Our site is hosted on a third-party CDN/hosting platform. Standard server-side access logs may be retained by them per their own privacy policies.

We do not use any analytics services, advertising networks, or session recording tools.

5. Data Security

Because all tool processing happens in your browser and we do not transmit your input data, the security of that data is governed by your own device and browser security. We recommend keeping your browser up to date.

For sensitive use cases — such as working with production JWT secrets, private keys, or passwords — we recommend using an offline or air-gapped environment, even with a client-side tool like ours.

6. Children's Privacy

API Dev Utils is not directed at children under 13 and we do not knowingly collect any personal information from children. If you believe a child has provided us with personal information, please contact us and we will promptly delete it.

7. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Continued use of the site after any changes constitutes acceptance of the new policy.
