octo is a different kind of tool site. We don't track you, we don't store your data, and we don't have a business model that depends on knowing who you are. Every tool runs entirely in your browser — your files, text, and images never leave your device.
Every file you upload to a typical online tool passes through a server — often on the other side of the world. That means someone else has a copy. With octo, there is no server. Processing happens in your browser tab using WebAssembly and modern JavaScript APIs. When you close the tab, everything is gone.
Most free tools are free because they sell your attention or your data. We think tools should just be tools. No analytics scripts, no tracking pixels, no cookies, no “optional” data collection. We don't want to know who you are. We just want you to have good tools.
Every line of code powering octo is open source and publicly auditable. You can inspect exactly what the tools do, verify that nothing leaves your browser, and even contribute improvements. No black boxes, no proprietary magic, no trust required.
To use octo, you simply visit the site. No sign-up, no login, no email address, no password. There's nothing to remember and nothing to lose. The tools are here whenever you need them, and they work exactly the same for everyone.
We don't collect, store, or even touch your data. Every tool runs locally in your browser.
