Privacy Policy
100% Local Processing
Your data never leaves your device. Here's exactly how we ensure your privacy.
Our Privacy Promise
We cannot access your data because it never leaves your browser.
All UsefulThings tools are designed with privacy by design. Every conversion, calculation, and processing operation happens entirely within your web browser. This isn't just a policy choice—it's technically impossible for us to access your data.
Technical Implementation
Static Site Architecture
Built as a static application with no server processing. All tools run entirely in your browser without external dependencies.
Offline Functionality
Once loaded, most tools work without internet connection. This proves no data is sent to external servers during processing.
No Backend Processing
We have no servers that could receive your data. File processing is handled entirely within your browser.
Cryptographic Security
Security-sensitive tools use your browser's built-in security features for secure operations without external dependencies.
What We Don't Collect
File Contents
We never see, store, or have access to any files you process. PDFs, images, videos, documents, and text remain entirely on your device.
Personal Information
No registration required. We don't collect names, emails, phone numbers, or any personal identifiers from tool usage.
Processing Data
Calculations, conversions, and generated content (like passwords or UUIDs) are never logged, stored, or transmitted.
Analytics & Advertising
Google Analytics
We use Google Analytics to understand which tools are most popular and how users navigate the site. This helps us improve the service. Analytics data is anonymized and doesn't include any content you process.
Google AdSense
We display ads to support the free service. Google may use cookies for ad personalization based on their privacy policies.
Verify Our Claims
Open Development
You can inspect the source code using your browser's developer tools. Look at the Network tab—you'll see no file uploads or data transmissions during tool usage.
Browser Extensions
Privacy-focused browser extensions and ad blockers would alert you to any unexpected data collection. Our tools work normally with all privacy extensions.
