Privacy
How information is handled when you use this website or contact support.
Updated October 26, 2026
Calculator inputs
The calculator runs in your browser. The website does not send the pay rates, hours, costs, or quotes you enter to a server. Cost downloads and printable estimates are generated on your device.
Saving on your device
Choosing “Save inputs” stores calculator values in your browser’s local storage. “Reset example” clears those saved calculator inputs. Your browser may also let you clear site data. Browser storage can be deleted or unavailable; keep your own copies of anything you need.
Technical website information
The site uses Cloudflare hosting and is also published through Sites. Hosting providers may process technical information such as your IP address, requested pages, and browser details to deliver and secure the website. The site offers optional first-party activity measurement. It does not use advertising pixels, session recordings, or a mailing-list form. The owner dashboard requires sign-in and is not a customer account service.
Read Cloudflare’s privacy policy for information about its services. The site uses system fonts and does not request fonts from a third-party font service.
Optional website analytics
Analytics are off until you choose “Allow analytics.” Declining does not limit the calculator. We honor Global Privacy Control and the browser Do Not Track signal. Use “Analytics preferences” in the footer to change your choice.
When allowed, we count predefined actions such as page views, calculator use, estimate openings, and template previews. We record only an approved page path, day, broad marketing source, approved campaign/content label, and a random identifier for a browser-tab session lasting up to 30 minutes. We do not collect calculator values, customer information, free text, full referral URLs, advertising IDs, IP addresses in our analytics database, or screen recordings. Hosting providers still process technical request information.
Your analytics choice is saved on this device; the short-lived analytics session is kept in session storage. The private dashboard reports the latest 30 days. Older activity is excluded from reports, and expired records are removed as new events arrive. If the service is inactive, older records may remain until it receives new activity. Declined visits and browser blocking mean these counts are incomplete. Data is processed using the Sites hosting infrastructure and its Cloudflare database.
When paid checkout is enabled, an approved marketing source and campaign label may be passed to Lemon Squeezy with your consent. The private sales report will store order identifiers, amounts, refunds, dates and those labels; it will not copy customer names, email addresses, postal addresses or payment details into analytics. Sales records are retained for business reconciliation. Contact support about access or deletion requests.
Support correspondence
If you email detailingcostbook@proton.me, your email address and message are used to respond and handle your support request. Correspondence is handled through Proton Mail. Avoid including customer records or sensitive information. You can contact the same address to request deletion of support correspondence, subject to any applicable recordkeeping requirements.
Payments
There is currently no checkout or payment form on this website. This notice will be updated before paid sales begin to explain any payment-provider information flows.
