Privacy Policy: FileDiffs
Last Updated: April 2026
Effective Date: April 2026
FileDiffs is built with a privacy-first approach. All file comparison happens in your browser, ensuring your data stays on your device with no storage or retention.
1. Privacy-First File Processing (Browser-Local Architecture)
FileDiffs is built on a browser-local processing model, meaning all file comparison operations take place directly within your own device. Whether you are comparing PDFs, Word documents, Excel sheets, code files, or structured data, the entire process runs inside your browser using modern web technologies.
Your files are never uploaded, transmitted, or stored on any external server at any stage of the process. This architecture ensures that your data remains fully under your control, significantly reducing exposure to common risks such as server breaches, unauthorized access, or third-party interception. By keeping all processing local, our system provides a secure and efficient environment for handling sensitive documents without compromising privacy.
2. No File Storage or Data Retention
FileDiffs follows a strict zero-retention policy for all user files. We do not store, access, index, or analyze the contents of your documents at any point—either during or after the comparison process.
All file processing is temporary and session-based, meaning your data exists only in your browser’s memory while you are actively using the tool. Once your session ends—whether by closing the tab, refreshing the page, or completing your task—no file data is retained by the platform. This approach ensures that your sensitive information remains private, with no residual data stored or accessible to our team or any third party.
3. Limited Information We May Collect
While FileDiffs does not collect or process your file data, we may gather minimal, non-personal technical information to maintain performance, reliability, and security. This may include details such as your browser type and version, device category, general geographic region, and basic interaction data like pages visited or features used.
This information is collected under a strict data minimization approach and is used solely to improve system performance, identify technical issues, enhance user experience, and protect the platform from abuse. It does not include personally identifiable information and is never used for intrusive tracking, profiling, or resale to third parties.
4. Contact Information (When You Reach Out)
If you choose to contact us through our support or inquiry forms, we may collect the information you voluntarily provide, such as your name, email address, and the details of your message. This information is used solely to understand your request and provide an appropriate response or technical assistance.
We maintain a strict no-spam policy. Your contact details are never used for unsolicited marketing, promotional emails, or unrelated communication. Additionally, we do not sell, rent, or share your personal information with third parties for commercial purposes. Any information you provide is handled responsibly and only for the purpose of supporting your inquiry.
5. How We Use Data
The limited, non-personal data we collect is used carefully and only to support the functionality, reliability, and security of the platform. This includes maintaining system performance, identifying and resolving technical issues, improving features based on real user interactions, and protecting the platform from misuse or malicious activity.
Our approach follows the principle of data minimization—collecting only what is necessary and using it only for clearly defined purposes. We do not use your data for profiling, resale, or advertising beyond standard platform operations. FileDiffs is committed to ensuring that any data usage remains transparent, limited, and aligned with user trust.
6. Cookies & Local Storage
FileDiffs uses essential cookies and local storage technologies to enhance your browsing experience and improve usability. These technologies allow the platform to remember certain preferences, such as theme settings (like dark mode), selected tool configurations, and session-related choices that help streamline your workflow.
These cookies do not store sensitive personal data or file content. Instead, they act as a lightweight memory system to make your experience smoother and more consistent across sessions. You have full control over cookie usage and can manage or disable them through your browser settings at any time. However, please note that disabling cookies may affect certain features or reset your preferences when you revisit the platform.
7. Advertising & Third-Party Services (Google AdSense)
To keep these tools free and accessible to users worldwide, we display advertisements through trusted third-party partners such as Google AdSense. These services help support the ongoing development, maintenance, and performance of the platform.
Third-party vendors, including Google, may use cookies and similar technologies (such as the DoubleClick cookie) to deliver ads that are more relevant to your interests. These ads may be based on your previous visits to this site or other websites across the internet.
It’s important to note that the platform does not control how third-party advertisers collect, store, or use data. Their practices are governed by their own privacy policies. You can manage your advertising preferences or opt out of personalized ads at any time by visiting Google Ads Settings or www.aboutads.info.
8. Data Security
We implement industry-standard security measures to protect your interaction with the platform. This includes secure HTTPS encryption to safeguard all data transmitted between your browser and our website.
In addition, our browser-local processing model ensures that your files remain on your device, significantly reducing exposure to risks commonly associated with cloud-based systems, such as server breaches or unauthorized data access. While no online system can guarantee absolute security, our architecture is designed to minimize risk and provide a safer environment for handling sensitive files.
9. Your Privacy Rights
We believe that users should have clear visibility and full control over how their data is handled. The platform is designed to minimize data collection by default, while still giving you the ability to manage your privacy preferences in a simple and transparent way.
As a user, you have the right to control your experience on the platform, including the ability to manage or disable cookies through your browser settings, request the deletion of any personal information you have shared with us (such as through contact forms), and use our services without creating an account or providing personal data. You can also limit data sharing through your device or browser-level privacy controls, depending on your preferences.
We respect these choices and aim to make our practices easy to understand and accessible to all users. Our approach aligns with widely accepted global privacy standards, including principles found in GDPR and similar frameworks, ensuring that your rights are recognized and supported regardless of where you access the platform.
10. Children’s Privacy
The platform is not intended for use by children under the age of 13, and we do not knowingly collect or process personal information from children. FileDiffs is designed for general productivity and professional use, and we encourage parental guidance if younger users access online tools.
If we become aware that personal information from a child has been collected unintentionally, we will take immediate steps to remove that data from our systems and prevent further collection. Protecting user privacy at all levels, including for minors, is an important part of our responsibility.
11. Updates to This Policy
We may update this Privacy Policy from time to time to reflect improvements to our comparison tools, changes in technology, or updates to legal and regulatory requirements. As our platform evolves, we want to ensure that our privacy practices remain clear, accurate, and aligned with current standards.
Any updates will be posted on this page with a revised effective date, so you can easily review what has changed. We encourage users to check this page periodically to stay informed about how their data is handled and protected.
