Privacy Policy
Last updated: 15 October 2026
Motiva Dental turns photos and videos taken with a phone into 3D models of teeth and faces, with screening measurements. This page explains what we collect, why, who else handles it, how long we keep it, and how to have it deleted. “We” and “us” means Motiva Dental. For anything about your data, write to [email protected].
The short version. Your scan photos, videos and 3D models are used only to make and show your scan. We do not sell them, use them for advertising or share them for others’ marketing. We use them to improve our reconstruction only if you say yes. You can ask us to delete them at any time.
What we collect and why
| What | Why |
|---|---|
| Your account: username or email address, and a securely hashed password | To sign you in and keep your scans private to your account |
| If you sign in with Google: your email address, name and Google’s account number for you | To sign you in. We do not receive your Google password, contacts or files |
| Scan photos and videos of your mouth, teeth or face | To build your 3D model. This is the core of the service |
| Results made from them: 3D models, measurements, coverage maps and the screening report | To show you your scan and its results |
| Capture details: which guide step each photo came from, sharpness, timing, and phone camera information in the photo or video | To check the scan is complete and to tell you which areas to rescan |
| Technical logs: time of each request, your IP address and browser type, and error messages | To keep the service secure and fix problems |
Health information
Photos and 3D models of your teeth and face can reveal information about your health, and they show your face. We treat them as sensitive. We process them only because you chose to scan, and only to provide the scan to you or to the clinic you are scanning for. You can withdraw that choice at any time by asking us to delete your scans.
Motiva Dental is an experimental screening aid, not a diagnostic device. Measurements are estimates, and any finding must be reviewed by a licensed dentist.
Using scans to improve Motiva Dental
Better accuracy comes from testing the system on real scans. We will use your scans to test and improve our reconstruction only if you give separate permission, and you can withdraw it at any time. Without that permission, your scans are used only to make your own results. We test mainly on models and casts, not people.
Who else handles your data
- Hosting: our servers are rented from a hosting provider (Contabo). Your account, scans and results are stored there.
- GPU processing: to build detailed 3D models, your scan images are sent to a GPU computing provider (RunPod), which uses them only to run that job.
- Network: our domain and email run through Cloudflare, which passes traffic to our server.
- Sign-in with Google: Google, if you choose to use it.
These providers handle data only to run the service for us. We do not sell your data or share it with advertisers or data brokers. We disclose it to others only if the law requires it, or if you ask us to (for example, to send a scan to your dentist).
How long we keep it
- Scans and results: kept in your account until you ask us to delete them, or until your account is deleted. A delete button in the app is on the way; until then, email us.
- Unfinished uploads: deleted automatically after 24 hours.
- Technical logs: kept for a short time to fix problems, then removed.
- Your account: kept until you ask us to delete it.
Cookies
We use one cookie to keep you signed in, and a short-lived one while you sign in with Google. We do not use analytics, advertising or tracking cookies.
Your rights
You can ask us for a copy of your data, to correct it, to delete it, or to stop using it. Write to [email protected] from the email address on your account, and we will reply within 30 days. Depending on where you live, you may also have the right to complain to your local data protection authority.
Security
Connections to Motiva Dental are encrypted (HTTPS), passwords are stored only in hashed form, and your scans and 3D models can only be opened while you are signed in to the account that made them. No system is perfectly secure; if a breach affects your data, we will tell you as the law requires.
Children
Anyone under 16 must have a parent or guardian take or approve the scan, and the account should belong to the parent, guardian or clinic. If you think a child’s data reached us without that, write to us and we will delete it.
Changes
If we change this policy, we will update the date at the top. If the change affects how your scans are used, we will tell you in the app before it takes effect.
