Calculator inputs
CBC Calc provides masonry planning calculators and guides. Calculator inputs and results are processed in your browser. The calculator application does not submit those inputs to a server or require an account. Copying an estimate uses your device clipboard; printing uses your browser. Do not enter personal or confidential information in calculator fields.
Website requests and service providers
Visiting a page sends ordinary request information, such as your IP address, browser information, requested URL and request time, to the hosting and network services that deliver the website. Those services may process logs to deliver, secure and troubleshoot the site. This application does not define a separate retention period for provider logs.
Email you send
If you email cindercalc@gmail.com, your address and message are handled through the email provider and used to respond to your inquiry or investigate a correction. Avoid sending sensitive information. You may contact the same address to request deletion of correspondence; applicable provider limitations or legal obligations may affect a request.
Optional Google advertising
Advertising is disabled in the application unless the site operator configures it. When enabled and permitted by the consent integration, Google AdSense can request ads and process information such as IP address, device/browser information, ad interactions and identifiers stored in cookies or similar technologies. Google and its partners may use that information for ad delivery, measurement, fraud prevention and, where permitted, personalized advertising. Calculator field values are not intentionally sent as ad parameters.
Read how Google uses information from partner sites and Google's privacy policy. See our cookie and advertising choices for available controls. The site operator must configure and maintain any required regional consent message before enabling ads.
Your choices and questions
You can control or clear cookies through your browser, use Google's ad settings, and use a consent message when one is provided. Clearing cookies may reset saved choices. Contact cindercalc@gmail.com for privacy questions or requests relating to applicable access, correction or deletion rights. Do not send identification documents unless a secure, appropriate verification method has been agreed.
External links and changes
External websites have their own privacy practices. This notice describes this application's operation and may change when its services or data handling change. Check the update date above.
