Information we collect

The details you enter in our inquiry form, with the page you sent it from and your browser's time zone. For inquiry and SMS rate limits, the application stores a keyed hash of the connection’s IP address.

For SMS sign-in, we verify your mobile number with a one-time code and keep the number private. For GitHub or Google sign-in, we store the provider's account identifier so you can return to the same account. Your browser uses a session cookie to keep you signed in. We record the projects you like and the file versions you download, counting a download once per account, version and day. Projects you publish, with their pictures and files, are stored with your account and shown according to the visibility you choose.

If you buy parts, we receive the items ordered, amount paid, payment status, contact details and delivery address. Stripe handles your card details; Maker Harbor does not receive your full card number.

We count Buy clicks and checkout starts by date, country and product without storing an identity or cookie with those counts.

How we use it

To respond to your inquiry, process and ship orders, sign you in, show your account and the projects you publish, and count project activity. We don't sell personal information.

Service providers

We keep account, inquiry, project, exhibit and order records in a database on our website server. Our SMS provider receives your mobile number and one-time code to deliver sign-in messages. Stripe processes payments and keeps payment records. When team notifications are enabled, Resend delivers a copy of each inquiry to our team. If you allow cookies, we use Google Analytics. You can change this anytime under “Analytics choices”.
