Every calculation on PercentLab is handled by JavaScript in your browser. The amounts, rates and results you enter are not sent to any server and are not stored.

Browser storage

Only the display theme (light/dark), the decimal-places setting and the last tab you opened are saved in this device's localStorage. You can delete them at any time in your browser settings.

Ads and cookies

Kakao AdFit ads may be shown to support the site. The ad provider may use its own cookies or similar technologies to serve and measure ads, which are governed by that provider's privacy policy.

Offline cache

For faster repeat visits, a service worker caches only static files such as styles and scripts. Your inputs are never cached.
