3D Print Quest Privacy Policy
Last updated October 23, 2026
About this policy
3D Print Quest collects only what it needs to run lessons, and never sells student information or shows ads. This policy explains what we collect, why, who helps us run the service, and how to have information deleted.
3D Print Quest is a service of STEMstarters LLC ("we", "us"), a North Carolina limited liability company. It covers the 3D Print Quest app at app.stemstarters.com and its waitlist page.
What we collect
Students never create accounts, and we never ask for a student's email, password, birthday, photo or last name.
| Who | What we collect | Why |
|---|---|---|
| Teachers and parents (account holders) | Name or display name, email address, password (stored scrambled, we can't see it), class names, class settings | To sign you in and run your classes |
| Students | A first name or nickname the teacher types in, which steps and lessons they finished, which lesson they picked, badges earned | To show progress and award Builder Badges |
| Students | 3D design files (.stl) they turn in | So the teacher can review and print them |
| Paying members | Billing name, email, plan and payment status (card numbers go straight to Stripe; we never see or store them) | To manage memberships |
| Waitlist sign-ups | First name and email address | To send launch news you asked for |
| Everyone | Basic technical data our providers log automatically, like IP address, browser type and time of visit | To keep the service secure and working |
The app saves a small note in the browser so a student's device remembers which class and name they picked. It is cleared when the student taps Log out. We do not use advertising or tracking cookies.
How we use information
We use information only to provide 3D Print Quest: running classes, showing progress, sharing turned-in designs with the teacher, managing memberships, answering support requests, and keeping the service secure.
We will never:
- Sell or rent student information
- Show ads in the app, or use student information to target ads anywhere
- Build profiles of students for any purpose other than their lessons
- Use student information to train AI models
- Share student information except as described in this policy or required by law
We may use totals that identify no one, such as how many lessons were completed this month, to improve the lessons.
Schools, parents and children's privacy
Schools (FERPA). When a school or teacher uses 3D Print Quest, the student information they enter stays under the school's control. We act as a "school official" with a legitimate educational interest: we use the information only to provide the service and do not share it further. Schools can ask us to sign a data privacy agreement, such as the Student Data Privacy Consortium's National Data Privacy Agreement, at hello@stemstarters.com.
Children under 13 (COPPA). In a school, the school gives consent on parents' behalf for this educational use. Parents may ask the school to review or delete their child's information, and the school can ask us to do so.
Homeschool families and clubs. When a parent or club leader creates a class outside a school, they give consent for the children they add and can view or delete that information at any time.
North Carolina. We follow North Carolina's Student Online Protection Act: no targeted ads, no student profiles beyond school purposes, no selling student information, and deletion within 45 days when a school asks.
Service providers
These companies help run 3D Print Quest. Each handles only what its job needs and is bound by its own privacy and security terms.
| Provider | What it does | What it handles |
|---|---|---|
| Supabase | Database, sign-in and file storage (US data center) | Accounts, classes, student first names and progress, design files, step photos |
| Stripe | Payments | Billing details and card numbers (teachers and parents only) |
| Kit | Waitlist and email | Names and emails of people who sign up |
| Cloudflare | Hosts the website pages | Technical data such as IP addresses |
| YouTube | Lesson videos, shown in privacy-enhanced mode | Technical data when a video is played |
| Google Fonts, cdnjs and jsDelivr | Fonts and code libraries the pages load | Technical data such as IP addresses |
Student information is never sent to Stripe, Kit or YouTube.
Security
We use reasonable safeguards to protect information, including:
- All connections are encrypted (https)
- Each teacher can see only their own classes, enforced by the database itself
- Step photos and design files are stored privately and shared only through links that expire within hours
- Passwords are stored scrambled; we cannot read them
- Two-step login on every account we use to run the service
- Daily backups
No system is perfectly secure. If a breach affects your information, we will notify affected schools and account holders without unreasonable delay, as North Carolina law requires.
How long we keep information
We keep student information only as long as a class needs it, and teachers can delete it at any time.
| Information | How long we keep it |
|---|---|
| Turned-in design files | Deleted when the teacher marks the design printed, or when the class is deleted |
| Students and their progress | Until the teacher removes the student or deletes the class; classes with no activity for 100 days are deleted automatically |
| Teacher and parent accounts | While the account is open; deleted within 90 days of a request to close it |
| Billing records | As long as tax and accounting law requires (kept by Stripe) |
| Waitlist emails | Until you unsubscribe |
| Backups | Copies roll off within 7 days |
To request deletion, email help@stemstarters.com. We complete school deletion requests within 45 days.

- Teachers and parents can see, change or delete their classes and students in the app, and can ask us for a copy of their information or to close their account.
- Parents of students in a school class can contact the school, or us, to review or delete their child's information.
