Functional Cookies

With your consent, we use functional cookies (via local storage) to remember your calculator inputs so you don't lose your work when you return.

Advertising Cookies

We use Google AdSense to display advertisements. Google and its partners may use cookies to serve ads based on your prior visits to this website or other websites. See the "Advertising" section below for more details.

You can also manage cookies through your browser settings at any time.

Advertising

Calculy.org is supported by advertising through Google AdSense.

How Google AdSense Works

Google AdSense uses cookies to serve ads. These cookies enable Google and its partners to serve ads based on your visits to Calculy.org and/or other websites on the Internet.

Personalized vs. Non-Personalized Ads

  • Personalized ads — If you consent to advertising cookies, Google may show ads based on your interests and browsing history.
  • Non-personalized ads — If you do not consent, you will see ads that are not based on your personal data, but may still be contextually relevant to the page content.

Your Choices

You have control over how ads are personalized:

  • Use our cookie consent banner to accept or reject advertising cookies
  • Visit Google Ads Settings to manage your ad personalization preferences
  • Visit aboutads.info to opt out of personalized advertising from many ad networks

Third-Party Vendors

Google and other third-party vendors use cookies to serve ads based on your prior visits. A list of Google's advertising partners can be found at Google's partner list.

Third-Party Services

In addition to Google AdSense, we may use the following third-party services:

  • Google Fonts — to display typography (no personal data collected)
  • Netlify — our hosting provider (see their privacy policy)

We do not sell, trade, or transfer your personal information to third parties.

Your Rights (GDPR / EEA Users)

If you are located in the European Economic Area (EEA), you have certain rights under the General Data Protection Regulation (GDPR):

  • Right to access — request information about data we hold

  • Right to restrict processing — limit how we use your data
  • Right to data portability — receive your data in a portable format
  • Right to object — object to certain processing activities
  • Right to withdraw consent — withdraw consent at any time

Data Security

We use industry-standard security measures to protect our website:

However, no method of transmission over the Internet is 100% secure, and we cannot guarantee absolute security.
