Privacy Policy
Last updated: February 1, 2026
The short version: We don't collect your personal data. Our tools run entirely in your browser, and we don't store or transmit any information you enter.
Introduction
Curious Utilities ("we," "our," or "us") operates the curiousutilities.com website and its associated subdomains. This Privacy Policy explains how we handle information when you use our services.
We are committed to protecting your privacy. Our tools are designed to work entirely client-side, meaning your data stays on your device and is never sent to our servers.
Information We Don't Collect
Our developer tools (JSON Formatter, JWT Decoder, Unix Timestamp Converter, etc.) process data entirely within your browser. We do not:
- Collect or store any data you input into our tools
- Require you to create an account or provide personal information
- Track your individual usage patterns or behavior
- Sell or share personal data with third parties
Information That May Be Collected
While we don't collect personal data, some information may be collected through:
Analytics
We may use privacy-focused analytics services to understand general usage patterns, such as which pages are visited and approximate geographic regions. This data is aggregated and cannot be used to identify individual users.
Advertising
We use Google AdSense to display advertisements. Google may use cookies to serve ads based on your prior visits to our website or other websites. You can opt out of personalized advertising by visiting Google's Ads Settings.

Like most websites, our hosting provider may automatically collect technical information such as IP addresses, browser types, and access times. This data is used solely for security and operational purposes and is not linked to personal identities.
Cookies
Our website may use cookies for the following purposes:
- Essential cookies: To remember your preferences (like dark mode settings)
- Advertising cookies: Used by Google AdSense to serve relevant ads

You can control cookies through your browser settings. Disabling cookies may affect some functionality but will not prevent you from using our tools.
Third-Party Services
Our website integrates with the following third-party services:
- Google AdSense: For displaying advertisements
- Google Fonts: For typography
These services have their own privacy policies, and we encourage you to review them.
Data Security
Since we don't collect or store your personal data, there's minimal risk of data breaches affecting your information. Our website is served over HTTPS to ensure secure connections.
