Privacy Policy

Last updated: today

Calculator privacy

All calculations run entirely in your browser. We do not collect or store the values you type into any calculator on this site. Calculator inputs and results stay within the calculator experience on your device.

Shared calculator links may include the values you entered, but only when you choose to copy and share that link. You are in control of what you share.

Optional email signup

You may optionally submit your email address to receive updates about new calculators, printable worksheets, and small-business resources. Signing up is entirely voluntary.

• Downloads are never blocked if you choose not to sign up.
• Submitting your email requires checking the consent checkbox.
• Your email is stored securely in the site backend and is not publicly visible.
• We do not sell or share subscriber emails with third parties.

Analytics

We may use privacy-conscious analytics to understand which pages and tools are most useful. Analytics events are sanitized to avoid sending email addresses, names, raw calculator input values, calculated results, or other sensitive values.

Analytics provider scripts are only loaded when the site owner enables them. If no provider is configured, no analytics script runs.

Admin & security

Email subscriber data is only accessible through protected admin tools. Public visitors cannot browse or search subscriber records. The list is not exposed through the site.

Advertising

In the future, this site may display advertisements (for example, Google AdSense) in clearly marked ad spaces. Advertisers may use cookies subject to their own privacy policies.

Unsubscribe or removal requests

You can request that your email address be removed from the subscriber list at any time. To do so, contact us through the contact page and include the email address you signed up with.
