When you calculate your BMI, Salary, or Password Strength, that math happens inside your browser. We never see it, and we never save it to a database.
You might notice we remember your "Recently Used" tools. That's using a technology called Local Storage. Think of it like a sticky note on your own computer screen. We can't read it remotely, and you can wipe it anytime by clearing your browser cache.
We do use reputable third-party partners (like Google) to show ads. To make those ads relevant, they might use cookies. That's standard for the web, but we want you to know about it. You can always opt-out through your Google Ad Settings.
While we use HTTPS encryption to protect the connection, you should always act responsibly. Don't calculate sensitive things (like real passwords or bank details) on public Wi-Fi computers you don't trust.
If you have concerns, just reach out. We are real people building free tools for the community.
