Privacy Policy
Last updated: 27 April 2026
1. Introduction
CalcCore.io ("CalcCore", "we", "us", "our") is committed to protecting your privacy. This Privacy Policy describes what data we collect, why we collect it, and how we use and protect it when you visit or use calccore.io (the "Site").
By using the Site, you agree to the collection and use of information in accordance with this policy. If you do not agree with any part of this policy, please discontinue use of the Site.
2. Calculator & Tool Inputs — What We Do Not Collect
All CalcCore calculators and tools run entirely in your browser (client-side JavaScript). We do not collect, store, transmit, log, or have any access to values you enter into any calculator or tool on the Site. Your inputs never leave your device and are not sent to our servers.
We do not require account registration and we do not collect names, email addresses, or any personally identifiable information through the normal use of our calculators and tools.
3. Data Collected Automatically
When you visit the Site, certain technical data may be collected automatically by third-party services we use (see sections 4 and 5). This data may include:
- IP address (typically anonymised before storage);
- browser type, version, and language;
- operating system and device type;
- pages visited, time on page, and navigation path;
- referring URL (the page that linked you to our Site);
- approximate geographic location (country or region level only).
This data is collected in aggregate form and is not used to identify individual users.
4. Analytics — Google Analytics
We use Google Analytics (provided by Google LLC) to understand how visitors interact with the Site. Google Analytics collects anonymised usage data via cookies and similar tracking technologies. This data helps us improve the content, structure, and usability of the Site.
Google Analytics data is processed and stored by Google in accordance with their privacy policy. We have enabled IP anonymisation to further protect user privacy. We do not use Google Analytics to identify individual users or combine analytics data with personally identifiable information.
You can opt out of Google Analytics tracking by installing the Google Analytics Opt-out Browser Add-on, available from Google's website. For more information, please refer to Google's Privacy Policy.
5. Advertising — Google AdSense
We display advertisements served by Google AdSense (Google LLC). Google AdSense uses cookies and similar technologies to serve ads that may be relevant to your interests, based on your prior visits to this Site and other websites across the internet.
We do not control which ads are displayed or the data practices of Google in connection with advertising. Google may share data with its advertising partners in accordance with its own policies.
You can manage your ad personalisation preferences or opt out of interest-based advertising through Google Ad Settings. For more information, please refer to Google's Ads Privacy Policy. You may also opt out of interest-based advertising from participating third-party vendors via the Network Advertising Initiative or the Digital Advertising Alliance opt-out tools.

The Site may contain links to external websites. CalcCore is not responsible for the privacy practices, content, or availability of those websites. We encourage you to read the privacy policy of any external site you visit.

11. Security
We take reasonable technical and organisational measures to protect the Site and any data in transit. The Site is served over HTTPS to encrypt data between your browser and our servers. However, no method of transmission over the internet is completely secure, and we cannot guarantee absolute security.
12. International Transfers
CalcCore is operated from within the European Economic Area. Third-party services such as Google may transfer and process data in countries outside the EEA. Google relies on Standard Contractual Clauses and other approved transfer mechanisms to ensure adequate protection for such transfers.
