This policy applies to the current version of CalculatorNest.pro. Last updated: October 17, 2026.
Calculator data
The numbers and dates you enter are processed locally in your browser. The calculator code does not send these inputs to a server or save them in a user account. We have not added visitor analytics tools to the website code. Local calculation does not mean the hosting service processes no technical data; see the hosting section below.
Storage on your device
When you switch language on a calculator page, valid inputs may be transferred temporarily to the other-language page within the same tab using local session storage. Transfer data are removed when loaded, expire after five minutes, and are not added to the page URL or sent to a server. Your language choice is not saved as a permanent preference.
Your favorite calculators are saved in the browser's local storage. When you choose to save a calculation, its label and inputs are stored on the same device, up to ten saved calculations per calculator. The result is recalculated when you load it. These data remain until you delete them or the browser clears the site's storage. They do not sync with another account or device. Anyone using the same browser may be able to see them, so avoid saving sensitive information on a shared device.
Control over your data
You can remove a favorite by pressing its favorite button again, delete saved calculations from their list, or clear all site data in your browser settings. Copying a result to the clipboard happens when you press the copy button. CSV downloads and printing happen at your request and may include your inputs and results. Clearing site data does not delete a copy you have already downloaded or printed; remove those copies from your device when needed.
Hosting
Hostinger hosts this public version of the website. The hosting service may process technical data such as your IP address, request time, and browser information to operate and protect the service. You do not need to sign in to use this website. The Hostinger privacy policy explains how it handles the data it processes.
Advertising and cookies
Advertising is currently disabled in this version, and the website does not load Google advertising code. The following section describes how advertising data would be handled if this service is introduced.
When advertising is enabled and allowed to load, third-party vendors, including Google, may use cookies to serve ads based on your prior visits to this website or other websites. Google's advertising cookies enable it and its partners to serve ads based on your visits to this website and/or other websites on the Internet. These services may also use identifiers and technical data to display and measure ads and prevent fraud.
You can control or opt out of personalized advertising from Google through My Ad Center. You can also review personalized-advertising opt-out choices for participating third-party vendors at AboutAds; participating vendors and available choices vary by country and browser. Opting out of personalization does not turn off all ads.
Learn how Google uses information from partner sites and read Google's privacy policy. If advertising is introduced or data-processing services change, this policy will be updated to reflect the services used and available consent choices.
