Privacy policy
Last updated July 7, 2026.
Slopeify (slopeify.com) is built so that using the calculator does not require handing over personal information. This page explains exactly what we collect, when, and why.
The calculator itself
The wall designer runs entirely in your browser. The numbers you enter (height, soil type, surcharge, and so on) are never sent to our servers. There is no account, no login and no database record of your project. If you use "Copy share link," your inputs are encoded directly into the URL, which only you hold.
Analytics
We use Vercel Web Analytics to understand which pages get traffic and how the site performs. It is cookieless and reports aggregated counts (page views, referrers, rough device/location), not individual browsing history tied to you.
Affiliate and referral links
Materials takeoff lines link out to retailers (Home Depot, Amazon) and, where configured, the "find a pro" CTAs link to a contractor or engineer matching partner. Some of these are affiliate or referral links: if you buy through one or submit a match request, we may earn a commission at no extra cost to you. Once you click through, that retailer or partner's own privacy policy governs the data they collect, not ours. We only pass along the minimal job context needed for the match (for example, your state and wall height), never your name, address or contact details, unless you choose to share those directly with them.
If you email hello@slopeify.com (for example, to ask about the Pro report or to get matched with a pro before the matching network covers your region), we use your message and reply address only to respond to you or make that introduction. We do not add you to a mailing list from a support email.
Payments
The Pro design report is purchased through Stripe's hosted checkout. We never see or store your card number; Stripe processes the payment under its own privacy policy and PCI compliance obligations. We receive confirmation that a purchase happened and the report is delivered to the email you provide at checkout.
Cookies
We do not set advertising or tracking cookies of our own. Third-party links (retailers, payment processor, matching partners) may set their own cookies once you leave slopeify.com, governed by their policies.
Your choices
Because we hold no account and no project database, there is nothing to export or delete on our end beyond email correspondence. To have an email exchange removed, contact us at hello@slopeify.com.
Changes
If this policy changes in a material way, we will update the date at the top of this page.
