Privacy
Your data stays yours.
BiyoTool is designed to keep everyday calculations and tool work in your browser. This page describes the current behavior plainly, including the small amount of preference storage and the external font request used by the site.
Browser-local work
Calculations run on your device.
No app tracking
No observed analytics or advertising.
Browser-local processing
Calculators, converters, generators, and text tools operate within your web browser. Inputs, calculations, and generated results are not submitted by the application to a BiyoTool server or a third-party calculation service.
Local storage preferences
The site stores a small amount of preference data on your device using standard browser Local Storage:
- Your preferred light or dark theme.
- Your preferred currency for financial calculators.
These preferences are not used for identification, advertising, or usage tracking. The app does not currently use cookies or session storage.
Clipboard access
Some tools offer a Copy action. When you explicitly choose it, the browser clipboard API writes the displayed result to your device's clipboard. BiyoTool does not read your existing clipboard contents.
External services
The application does not currently include analytics, advertising networks, tracking pixels, or third-party embeds. The stylesheet requests the typefaces used by the design from Google Fonts, which is an external font delivery request subject to Google's own privacy terms.
Future changes
If the application later adds a feature that transmits information or changes how preferences are stored, this page should be updated to describe that behavior clearly before the change is relied on.
