Summary

Calcly does not collect, store, or transmit any personal data. All tool processing happens entirely in your browser.

Data Processing

Every calculation, conversion, and generation happens client-side using JavaScript. Your text, numbers, images, and files are processed locally and never sent to any server.

Local Storage

We use your browser's localStorage to save: your theme preference (dark/light), favorite tools, recently used tools, and usage counts. This data never leaves your browser. You can clear it at any time through your browser settings.

Cookies

Calcly does not use cookies of any kind — no analytics cookies, no tracking cookies, no advertising cookies.

Third-Party Services

We load Google Fonts for typography and two JavaScript libraries (QRCode.js, JsBarcode) from CDNs. These CDNs may log standard request data. No other third-party services are used.
