Terms and privacy
For IndustryKit at industrykit.io. Plain words on purpose. Last updated November 2026.
What this service does
You upload a mesh (STL, OBJ or PLY). We convert it to a NURBS body and show you the result in 3D with its measured accuracy. Converting and inspecting is free. Downloading the result as a STEP file is paid.
What you pay for
You buy credits (the smallest pack is shown before you pay). One credit downloads one solid body; a conversion with several bodies uses one credit for each. Unlocking a conversion lets you download it, as a part or as an assembly, as often as you like for 7 days. Credits do not expire. Payment is taken on the payment provider's own checkout page; we never see or store your card details.
Refunds
You can inspect the result before spending credits, so please do. If a file you unlocked will not open as a valid body in your CAD program, write to us within 14 days with the conversion's address and we will fix it or give the credits back. Unused credits are refunded on request within 14 days of buying them.
Your files
Your meshes and results stay yours. We claim no rights in them and use them only to run your conversion. Uploads and results are deleted automatically: after 24 hours if not paid for, after 7 days if paid. A conversion's page has an unguessable address; anyone you give that address to can see the result, so share it only with people you mean to.
Only upload models you have the right to convert.
What we keep
For your account: your email address and, if you chose a password, a salted hash of it (never the password itself); if you sign in with Google, the identifier Google gives us for you. Your credit balance and its history. For each conversion: the files until they are deleted, the settings you chose, the time, and your IP address (used to limit abuse of the free conversions). When you buy credits the payment provider keeps the payment record; we keep only its reference. One cookie keeps you signed in. No tracking scripts on this site. Write to us to have your account deleted.
Sharing
Each account has its own link. When someone new makes an account through it and confirms their email, the account that shared the link gets free credits (5 by default, for up to 100 people). Credits earned with made-up or duplicate accounts can be taken back.
Advertising
Once you confirm your email, we may share it with advertising platforms (such as Meta and Google) so they can find other people with similar interests and show them ads for IndustryKit. The platforms receive the email in a scrambled (hashed) form for matching, use it only for this, and do not show you ads because of it. We do not sell your email or share it for any other purpose. To opt out, untick "Use my email to find similar people for ads" in your account, or write to us.
No warranty
The result is a close surface fit of your mesh, with the measured deviation shown to you before you buy. It is not a reconstruction of the original design intent, and it is up to you to check that it suits your use. The service is provided as is, and our liability is limited to the amount you paid for the conversion in question.
