How dew point calculator inputs stay in your browser
Temperature, humidity, and dew point values are calculated in the browser. The site does not require an account, upload calculator inputs, or maintain a personal calculation history.
Personal data the weather calculators do not request
Using a calculator does not require a name, email address, location, account, payment details, or permission to access a weather sensor. Do not include personal or confidential information when entering values or sending a technical report.
The calculator fields are designed for numerical weather observations only. Values remain on the current device unless a browser feature, extension, accessibility tool, or user action outside this site records them.
Technical request logs and website analytics data
Hosting providers may process standard request data such as IP address, browser type, requested URL, and timestamps for security and reliability. If privacy-preserving analytics are added, this policy will be updated before their use.
Contact emails, calculator issue reports, and corrections
Messages sent by email include the information you choose to provide and the normal technical headers handled by email services. They may be used to answer a question, reproduce a calculator issue, correct content, and retain necessary correspondence.
Avoid sending sensitive personal data. A useful technical report normally needs only the page URL, anonymous input values, units, observed result, expected result, browser, and device type.
External weather source links and privacy policy updates
External source sites have their own privacy practices and are not controlled by dewpointcalculator.org. Following a link to the National Weather Service or another reference leaves this site's privacy scope.
This policy may be updated if hosting, analytics, contact handling, or calculator behavior changes. The current version appears on this page. Last reviewed: 2026-08-03.
