Privacy policy disclosures and site terms

Consent and cookie settings

Where required by law (such as in the EEA/UK/CH), analytics tools and advertising technologies run only after you provide consent. You can change or withdraw consent at any time.

Who we are (data controller)

STEM Calculators is the controller for data collected on this site. Contact: privacy@stemcalculators.app or contact form.

Microsoft Clarity

We use Microsoft Clarity to understand how visitors interact with the site. Clarity may capture interaction data such as clicks, scrolling, and page navigation, as well as device and browser information. This helps us improve usability and performance.

Microsoft may collect or receive this data in accordance with its privacy statement.

Google Analytics

We use Google Analytics to analyze site traffic and usage patterns. Google Analytics may collect information such as pages visited, time on page, device type, and approximate location derived from IP address. This data helps us understand what content is most useful.

Google Analytics 4 does not log or store IP addresses. For EEA/UK/CH traffic, the IP address is used only to derive approximate location and then discarded before logging.

Google AdSense advertising (Auto Ads)

We use Google AdSense Auto Ads to display advertising on this site. Google and other third-party vendors may use cookies or similar technologies to serve ads based on a user's prior visits to this site and/or other websites.

Ad serving and measurement technologies may collect information such as IP address, browser/device details, ad interactions, and usage signals. Third parties may place and read cookies, or use web beacons and other identifiers, in connection with ad delivery, reporting, fraud prevention, and measurement.

Where required by law (including in the EEA, UK, and Switzerland), we request consent before using cookies or other local storage and before collecting, sharing, or using personal data for personalized advertising. You can change or withdraw consent at any time using the site's privacy controls.

Non-personalized ads may still use cookies or similar technologies for functions such as frequency capping, aggregated reporting, and fraud/abuse prevention where legally permitted or consented to.

Information we collect

• Usage data: pages viewed, interactions, and navigation paths.
• Device data: browser type, operating system, screen size, and language.
• Approximate location based on IP address (analytics providers).
• Contact form data you choose to submit.

How we use data

• Improve calculators, content, and user experience.
• Monitor site performance and diagnose issues.

Legal basis (EU/EEA/UK/CH)

• Analytics: your consent, where required by law.
• Security and site operations: legitimate interests.
• Contact requests: performance of a service you request.

Cookies and opt-out

Our analytics tools and advertising providers may set cookies or similar identifiers. You can block or delete cookies in your browser settings and use provider opt-out tools where available. You can also change your choice anytime in Cookie Settings.

Third-party access

Analytics data may be processed by Microsoft and Google as our service providers. When Google AdSense is enabled, advertising and measurement data may also be processed by Google and other advertising technology vendors involved in ad serving on the site. We do not sell personal information. We share data only as required to deliver analytics, advertising (when enabled), and operate the site or as required by law.

Data retention

We keep analytics data according to the retention settings configured in our analytics tools. Contact form messages are retained only as long as needed to respond and for recordkeeping/security.

Your rights

• Access, correct, or delete your data where applicable.
• Withdraw consent for analytics and optional third-party site technologies at any time.
• Object to processing or request restriction where applicable.
• Submit a request via our contact form.

International transfers

Our analytics providers operate globally, which may involve processing outside your country, including in the United States. We rely on vendor safeguards and contractual protections where required.
