Your print files
Files you drop into the calculator are read in your browser and never uploaded. Only the print time and filament use are read from them, and nothing from the file is stored.
Saved settings
Your electricity price, hourly rate, markup, country and currency are saved in your browser's local storage so they're ready next time. They never leave your device. Clearing this site's data in your browser removes them.
Analytics
We count visits with Umami, which sets no cookies and collects no personal data. Alongside page views it records when a price is calculated, a file is read or can't be read (and which slicer made it), an affiliate link is clicked, and someone joins the waitlist. None of these include your file, your numbers or your email.
The Pro waitlist
If you join the waitlist, your email is sent throughWeb3Forms to our inbox. We use it only to tell you when Pro is ready. Reply to any email from us to be removed.
Affiliate links
"Buy this filament" links go to Amazon (www.amazon.com, www.amazon.co.uk, www.amazon.de) and to the Bambu Lab store through the Awin affiliate network. As an Amazon Associate we earn from qualifying purchases, and Bambu Lab pays us a commission through Awin. You pay the same price. Amazon and Awin set cookies on their own sites when you follow a link, to credit the sale.
