CalcTools is designed for utility-first use with minimal personal data requirements. Most tools work without account creation and without storing user-entered calculator values on our servers.
We may use cookies and similar technologies (such as local storage or browser identifiers) for basic site functionality, security, and performance.
We may add analytics tools in the future to understand usage patterns such as page views, device types, and performance trends. If enabled, analytics data is used to improve site quality and user experience.
Calculator input values are intended for on-page computation. Unless a feature explicitly states otherwise, tool inputs are not stored as personal profiles.
We may add advertising partners in the future. For example, if Google AdSense is enabled later, Google or its partners may use cookies or identifiers to show and measure ads.
Ad personalization means ads may be selected based on interests or browsing signals. Non-personalized ads are ads that are not based on personal interests but may still use limited context such as page topic or general location.
Ad placeholders shown on this site are layout reserves and do not always mean live ads are active.
Infrastructure providers may process technical request data (such as IP address and user agent) as part of secure web delivery and operations.
You can manage cookies through your browser settings and, when available, through consent controls on our site. You can also opt out of certain ad personalization settings through provider tools such as Google Ad Settings.
If we implement consent controls later, this policy will be updated with clear links to those choices.
