Data controller and contact
CalcMentor is operated by Vikhagen Online Services, organization number 927609894, Skarabakken 10, 6456 Skala, Norway. Privacy-related questions can be sent to contact@calcmentor.com.
Calculator inputs
The calculators run in the browser. Values entered into calculator forms are used to produce the result on the page and are not stored in a user account.
No account required
CalcMentor does not require users to create an account to use the calculators.
Hosting
CalcMentor uses Hostinger as shared hosting provider. Server logs may process technical information such as IP address, requested URL, timestamp, browser information and error data for security, troubleshooting and service operation.
Embedded calculators
Other websites may embed selected CalcMentor calculators with an iframe or the CalcMentor embed loader. When an embedded widget loads, CalcMentor may receive normal technical request data such as IP address, browser information, requested widget URL and referrer. The widget may also make calculator-specific data requests, such as exchange-rate or public-holiday lookups, when needed for that tool.
Cookies and consent
CalcMentor stores a small browser preference when you save cookie choices. Necessary storage is used to remember that choice. Optional advertising and analytics storage should only be enabled after consent where consent is required.
Google advertising
CalcMentor is prepared to show Google-served advertising, such as Google AdSense or Google Ad Manager. Google and its advertising partners may use cookies, local storage, device identifiers, IP addresses or similar technologies to deliver ads, measure ads, prevent fraud, limit repeated ads and personalize ads where permitted by law and consent choices.
Advertising data limits
Calculator input values should not be used by CalcMentor as advertising profile data. Sensitive health, finance, tax or personal calculator inputs should not be sent to advertising or analytics systems by CalcMentor.
Google Analytics
CalcMentor plans to use Google Analytics to understand aggregate site usage, page performance and content improvement opportunities. Analytics should be configured so calculator input values are not sent as event parameters, page titles or custom dimensions. Where consent is required, analytics storage should respect the visitor's cookie choice.
Local storage
The core calculators do not require saved calculation history. If a page offers browser-based features such as favorites or recent calculations, that page will identify what is stored locally.
AI features
CalcMentor does not use AI to perform deterministic calculations. Any optional AI explanation feature must be user-triggered, handled through a server-side endpoint, avoid exposing API keys and clearly explain what data is sent.
External links and third parties
Some pages link to official sources or supporting references. Google advertising services, Google Analytics, hosting services, embedded-widget host websites and external websites may have their own privacy policies and controller or processor roles.
Changing preferences
Use the cookie settings link in the footer to update advertising and analytics choices. Browser settings may also block or delete cookies and local storage.
