1. What Are Cookies?
Cookies are small text files stored on your device when you visit a website. They help websites recognize your browser and remember information about your visit.
2. Cookies We Use
Analytics cookies (Google Analytics 4). We use Google Analytics to measure aggregate site usage, which sets the following cookies:
• _ga (expires 2 years) — distinguishes unique users
• _gid (expires 24 hours) — distinguishes users within a day
• _gat (expires 1 minute) — throttles request rate
3. Local Storage (Not Cookies)
Theme preference. We use localStorage (not cookies) to remember your light/dark theme preference. This data is stored only on your device and is never transmitted to our servers.
4. Third-Party Cookies
Google. Google Analytics is provided by Google LLC. Google processes analytics data in accordance with its own privacy policy (policies.google.com/privacy) and may use it to improve its products and services. We do not currently use advertising cookies or any other third-party trackers.
5. Managing or Disabling Cookies
You can control cookies in several ways:
• Block or delete cookies through your browser settings (each browser — Chrome, Edge, Firefox, Safari — offers cookie controls);
• Use Google's opt-out browser add-on (tools.google.com/dlpage/gaoptout).
Note: analytics cookies do not affect how the calculators work — all tools function fully with cookies disabled.
