Overview
SlimPDF ("we", "us", "our") is committed to protecting your privacy. This Privacy Policy explains how we handle your information when you use our website at slimpdf.org.
File Processing
Your files never leave your device. All PDF and image processing on SlimPDF happens entirely in your web browser using client-side JavaScript. No files are uploaded to our servers or any third-party servers. We do not have access to any files you process using our tools.
This means:
- We cannot see, access, or store your files
- No file data is transmitted over the internet
- Your files remain on your device at all times
- The tools work offline once the page has loaded
Information We Collect
We do not collect any personal information such as names, email addresses, or account credentials. There is no user registration or login system.
We may collect anonymous, aggregated usage data through the following services:
Google AdSense
We use Google AdSense to display advertisements. Google may use cookies and similar technologies to serve ads based on your prior visits to this and other websites. You can opt out of personalized advertising by visiting Google Ads Settings.
Analytics
We may use analytics services to understand how visitors use our website. This data is anonymous and aggregated, and may include information such as pages visited, time spent on site, browser type, and device type. No personally identifiable information is collected.
Cookies
SlimPDF itself uses only a single localStorage entry to remember your dark/light mode preference. Third-party services (such as Google AdSense) may set their own cookies. You can manage cookie preferences in your browser settings.
Third-Party Links
Our website may contain links to external websites. We are not responsible for the privacy practices of those websites. We recommend reviewing their privacy policies separately.
