Data Handling & File Retention Policy
Your files never leave your device. Here's exactly how we handle your data.
Last Updated: 2024-12-01
🛡️ Key Highlights
1. How Client-Side Processing Works
Unlike many online tools that upload your files to remote servers for processing, EZOnlineToolz uses a fundamentally different approach:
Select File
You select a file from your device using the file picker
Local Processing
JavaScript in your browser processes the file entirely locally
Download Result
The processed file is generated in your browser and downloaded
🔒 At no point does your file leave your device or travel over the internet to our servers.
2. Types of Data We Handle
📄 Documents & PDFs
- •PDF files for merging, splitting, compression
- •Text documents for formatting, conversion
- •All processing done via PDF.js in browser
🖼️ Images
- •JPG, PNG, WebP, GIF, SVG files
- •Compression, resizing, format conversion
- •Processed using Canvas API in browser
📝 Text Input
- •Text for encoding, hashing, formatting
- •JSON, XML, YAML for validation/conversion
- •Never transmitted, stays in textarea
🔢 Numbers & Data
- •Numeric inputs for calculators
- •Data for generators (passwords, UUIDs)
- •All computed locally using JavaScript
3. Data Lifecycle & Retention
Here's the complete lifecycle of your data when using our tools:
Input Phase
When you select a file or enter text, it's loaded into your browser's memory (RAM). It never touches our servers.
Processing Phase
JavaScript code running in your browser processes the data. Temporary objects may be created in memory during processing.
Output Phase
Results are displayed on screen or offered as a download. Downloaded files go directly to your device.
Deletion Phase
When you navigate away, close the tab, or refresh the page, all data in memory is automatically cleared. There's nothing to delete because nothing was stored.
⏱️ Retention Period: ZERO
We have a zero retention policy. Since your data is never sent to our servers, there's nothing to retain. Data exists only in your browser's memory during the active session.
4. Local Browser Storage
Some features use your browser's local storage for convenience. Here's what may be stored locally on your device:
Theme (dark/light mode), language selection, tool-specific settings
Some tools may remember your last used settings (not your data)
Clearing Local Storage
You can clear all locally stored data anytime by:
- Clearing your browser's cache and cookies
- Using your browser's developer tools to clear localStorage
- Using private/incognito browsing mode (nothing persists)
5. Tools Requiring External Services
A small number of tools may require external API calls to function. When this is the case:
- ℹ️Some Tools Use External Services
Certain tools require external API calls to function (e.g., DNS lookups, IP geolocation, SPF/DMARC checks). These tools cannot operate purely client-side due to the nature of the data they need to retrieve.
- 📜Third-Party Policies
Data sent to external services is subject to those services' privacy policies.
Note: Even for tools using external services, we minimize data transmission and never store results on our servers.
6. Security Recommendations
While we've designed our tools with security in mind, here are best practices for handling sensitive data:
- ⛔Avoid Highly Sensitive Data
Don't paste private keys, passwords, or extremely confidential documents into any web-based tool—use offline alternatives for critical secrets.
- ✅Use Private Browsing
For extra privacy, use incognito/private mode—no data persists after closing the window.
- ✅Keep Browser Updated
Modern browsers have security features that protect client-side processing.
- ✅Verify the URL
Always ensure you're on the official https://ezonlinetoolz.com website.
7. Frequently Asked Questions
Can you see my files?
No. Your files are processed entirely in your browser. They are never uploaded to or visible by us.
What happens if I refresh the page?
All data in the tool is cleared. You'll need to re-upload or re-enter your data. This is by design—nothing persists.
Do you keep backups of my files?
No. Since files never reach our servers, there's nothing to back up. Your original file remains only on your device.
Is it safe to use these tools for work documents?
Yes, for most documents. Since processing is local, your work documents never leave your device. However, for highly classified or regulated data, always follow your organization's policies.
How can I verify files aren't being uploaded?
Use your browser's Developer Tools (F12) → Network tab. You'll see no file upload requests when using our tools. All processing is done via JavaScript in your browser.
