Privacy Policy

Core calculator inputs and results are processed locally in your browser whenever possible. CalcPlanet does not require an account for public calculators. Optional features such as analytics, ads, saved results, API tools, AI tools or contact requests may involve limited technical data as described below.

We use your browser's localStorage exclusively to save your preferences on your own device:

• Theme preference (dark / light mode)
• Favourite calculators
• Recently viewed calculators
• Language preference

This preference data is stored in your browser. Optional cloud features, analytics, ads, API tools or contact requests may involve limited technical data as described here.

To provide live data, CalcPlanet makes requests to these public APIs:

• CoinGecko API — live cryptocurrency prices (no user tracking)
• Frankfurter API — live currency exchange rates (European Central Bank data)

CalcPlanet uses a cookie consent banner that appears on your first visit and Google Consent Mode v2. Visitors in the EEA, UK and Switzerland: all analytics and advertising storage is denied until you accept — Google Analytics only receives cookieless, anonymous signals and sets no cookies. Visitors elsewhere (for example the United States): Google Analytics measures anonymous usage by default, while all advertising and personalisation stays off until you accept. Advertising, Microsoft Clarity and affiliate-tracking scripts load only after you accept. If you decline, Google Analytics is not loaded at all and only essential functionality cookies are used.

When you accept cookies, the following third-party services may load and place cookies on your device:

• Google Analytics 4 (measurement ID G-RBT36SFZV4) — anonymous usage analytics to understand how visitors use the site.
• Google AdSense — serves contextual advertisements and may use cookies for frequency capping and (with consent) personalisation.
• Microsoft Clarity — aggregated interaction and session-replay analytics used to find usability problems. Loaded only after you accept cookies.
• Skimlinks — automatically converts some outbound links to merchant sites into affiliate links, and may set a cookie to attribute a resulting purchase. It does not change any calculation result and costs you nothing.

You can withdraw consent at any time by clearing the cookie-consent choice in your browser storage or using the consent banner controls; withdrawal stops these scripts from loading on the next page view.

CalcPlanet is free to use and is funded by advertising and affiliate commissions. Display advertising is served by Google AdSense. Some outbound links to third-party merchants are affiliate links (managed by Skimlinks), which means we may earn a commission if you make a purchase. This never affects the numbers a calculator produces, the formulas we use, or which tools we recommend, and it never changes the price you pay.

• Right to access — request a copy of any data we hold about you
• Right to erasure — request deletion of your account and associated data
• Right to portability — export your saved data at any time
• Right to object — opt out of any optional data processing
• Right to withdraw consent — you can withdraw cookie consent at any time
