Privacy policy
Last updated: September 2026
This policy explains what information BlueprintCost ("we", "us") collects when you use blueprintcost.com and how it is used.
Calculator inputs
Calculations run entirely in your browser. The numbers you type are not sent to our servers. If you use Copy link, your inputs are stored in the page address so you can share them — only people you share the link with can see them.
Information collected automatically
Like most websites, our hosting provider and analytics tools may collect standard technical information such as your browser type, device, approximate location (country or region), pages visited and referring site. We use this in aggregate to understand which calculators are useful and to keep the site secure and fast.
Cookies and advertising
We may use cookies and similar technologies for analytics and advertising. Third-party vendors, including Google, may use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the internet. You can opt out of personalized advertising at Google Ads Settings or aboutads.info. Where required by law, we ask for your consent before setting non-essential cookies.
Affiliate links
Some links may be affiliate links. If you buy through them we may earn a commission at no extra cost to you. Retailers may set their own cookies under their own privacy policies.
Information you send us
If you email us, we use your address and message only to reply and to improve the site. We never sell personal information.
Your rights
Depending on where you live (for example California under the CCPA/CPRA, or the EU/UK under the GDPR), you may have the right to access, correct or delete personal information and to opt out of certain processing. Contact us at hello@blueprintcost.com to make a request.
