Your privacy is our fundamental principle. Learn how we protect your data.
At Online ToolStack, we believe privacy is a fundamental right. We've built our platform with privacy-by-design principles, ensuring that you can use our tools with complete confidence that your data remains yours alone.
All tools run entirely in your browser using JavaScript. No server processing means your data stays on your device.
We don't use cookies, analytics, or any tracking technologies that monitor your behavior across our site.
Your files are processed locally and never uploaded to our servers. They remain 100% private to you.
Use all tools immediately without creating an account. We don't collect emails, names, or personal details.

Should we ever need to update this privacy policy, we will prominently display changes on our website and maintain our core commitment to user privacy. We believe in being transparent about how we handle your data, even when that means telling you we don't handle it at all.
If you have any questions about our privacy practices or want to verify our technical implementation, please contact us. We're happy to provide technical details.
