At CompressUnder, your privacy is our top priority. This policy explains in clear, straightforward terms how we handle your data. We believe in complete transparency, so we have written this in plain language without legal jargon.
We do not upload, store, or have access to any of your files. All file compression happens directly in your browser on your device. Your files never leave your computer.
This is not a marketing statement. This is how our service fundamentally works. When you use CompressUnder to compress your images, videos, PDFs, or any other files, everything happens locally on your device. We have deliberately built our technology this way to ensure your complete privacy.
Let us be crystal clear about what we do not collect:
We collect minimal, non-personal information to operate our service:
Understanding how our service works will help you understand why your privacy is protected:
When you visit CompressUnder and select a file to compress, our compression technology runs entirely within your web browser. The file is read from your device, processed by code running on your computer, and the compressed file is created locally. At no point does your file travel over the internet to our servers.
Think of it like using a calculator on your phone. The calculator app does its work on your device without sending your calculations anywhere. Our compression tool works the same way, except it handles files instead of numbers.
This approach means that even if we wanted to see your files, we could not. We have no technical capability to access them because they simply never reach us.
CompressUnder is a free service that generates revenue through advertising. Here is how we handle ads:
We use Google AdSense to display advertisements on our website. We have chosen Google AdSense because it is a reputable advertising platform that respects user privacy and does not serve malicious or misleading ads.
Google AdSense may use cookies and similar technologies to show you relevant ads based on your browsing history across different websites. You can learn more about how Google uses data when you use our website by visiting Google's Privacy Policy.
Our website and Google AdSense may use cookies and similar tracking technologies. Here is what you should know:
You can control cookie settings through your browser preferences. Note that disabling certain cookies may affect your experience on our website or prevent ads from displaying properly.
While we do not share your files with anyone, we do use certain third-party services to operate our website:
Each of these services has its own privacy policy that governs how they handle data. We carefully select partners who respect user privacy.
Because your files are processed entirely on your device and never uploaded to our servers, they are as secure as your own computer. We cannot lose, leak, or mishandle data that we never receive in the first place.
For the minimal data we do collect (like usage analytics), we implement reasonable security measures to protect it. However, no method of transmission over the internet is 100% secure, so we cannot guarantee absolute security of data transmitted to our website.
You have complete control over your privacy when using CompressUnder:
Our service does not knowingly collect any information from children under the age of 13. We do not have user accounts or collect personal information, so children can use our service safely. However, we recommend that parents and guardians supervise their children's internet usage.
We may update this privacy policy from time to time to reflect changes in our practices or for legal reasons. When we make changes, we will update the "Last Updated" date at the top of this page.
We encourage you to review this privacy policy periodically. Significant changes will be prominently displayed on our website.
CompressUnder is available to users worldwide. Because all compression happens on your device, your files never cross international borders to reach our servers. The minimal data we collect (analytics, technical information) may be processed in different countries, but this data is anonymous and does not include personal information.
If you have any questions, concerns, or feedback about this privacy policy or our practices, we would love to hear from you. Transparency is important to us, and we are happy to address any questions you may have.
