What happens to your information

Calculator inputs are processed in your browser unless a feature clearly needs an external service. CalmCalc does not require an account to use its catalog.

Calculator inputs

Ordinary calculator values are computed in your browser and are not intentionally sent to CalmCalc servers. Local files selected for encoding or decoding are processed in your browser. Avoid entering sensitive personal information because no web interface can guarantee risk-free use.

Browser storage

Favorites and recently opened tools may be saved in local browser storage so they remain available on the same device. Clearing CalmCalc site data removes those preferences. Browsers can also let you block or delete cookies.

Advertising cookies and Google AdSense

CalmCalc is configured for Google AdSense site verification, but advertising is not currently activated in the site code. If advertising is activated on selected reviewed pages, third-party vendors, including Google, may use cookies, web beacons, or similar technologies to serve ads based on a user’s prior visits to CalmCalc or other websites. Google’s use of advertising cookies enables Google and its partners to serve ads based on those visits. These services may receive information such as an IP address, device or browser information, referring and visited pages, and interactions with ads.

You can manage or opt out of personalized advertising through Google Ads Settings. You can also review industry opt-out choices at AboutAds. If another advertising vendor is enabled in the future, its identity and opt-out information will be disclosed here.

Learn more about how Google uses information from sites that use its services and review Google’s advertising technologies. Before advertising is activated, required consent messages and vendor choices must be configured for the regions where they apply.

External services

The currency tool requests published exchange-rate information from Frankfurter through CalmCalc’s server endpoint. The monetary amount entered in the calculator is not needed for that request. Hosting and network providers may retain routine request logs for reliability, abuse prevention, and security; logs can include an IP address, user agent, requested URL, time, and diagnostic information.

Your choices and contact

You can clear local storage and cookies, block third-party cookies or advertising scripts, and use calculator pages that do not require an external data request. Privacy or correction questions can be submitted through the contact link in the site footer. This policy will be updated when data handling or advertising partners materially change.
