ToolCardio Privacy Policy
Last Updated: October 2026
1. Introduction & Client-Side Architecture
At ToolCardio ("we", "us", or "our"), accessible from https://toolcardio.com, the privacy of our visitors is our paramount architectural design principle. Unlike conventional web utilities that transmit your files, code, and text to remote application servers for calculation, ToolCardio processes data 100% locally on your device using client-side JavaScript, WebAssembly, and native browser APIs.
When you format JSON, generate cryptographic hashes, test regular expressions, or compress images on our platform, zero bytes of that content are uploaded to our servers or stored in any remote databases.
2. Information We Do Not Collect
Because all computational tools execute within your local web browser sandbox, we never collect, intercept, or inspect:
- Your source code, JSON payloads, or data schemas
- Your photographs, images, or media files
- Your generated passwords, cryptographic keys, or tokens
- Your search simulation parameters or draft URLs
3. Cookies, Local Storage & Advertising Partners
ToolCardio uses minimal cookies and local storage tokens solely to maintain basic website settings:
- Theme Preference: We store a simple
toolcardio_themevalue (either "light" or "dark") in your browser'slocalStorageto remember your display preferences. - Google AdSense & DoubleClick Cookies: Google, as a third-party vendor, uses cookies to serve ads on our site. Google's use of advertising cookies enables it and its partners to serve ads based on your visit to ToolCardio and/or other sites on the Internet.
- Users may opt out of personalized advertising by visiting Google Ads Settings or AboutAds.info.
4. Web Analytics & Server Logs
Like all standard web servers, our hosting infrastructure automatically logs non-personally identifiable technical information when you access our domain. This standard telemetry includes internet protocol (IP) addresses, browser user-agent strings, referring/exit pages, and date/time stamps. This aggregate data is analyzed purely for security monitoring and server capacity management.
5. GDPR and CCPA Data Protection Rights
Under the European General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA), you are entitled to exercise full control over your personal data. Because we do not collect personal profiles, accounts, or emails unless you voluntarily submit a support inquiry, we do not monetize or sell visitor data.
