Visualize Technologies LLC, a Colorado limited liability company doing business as VZN ("Visualize Technologies," "we," "our," or "us"), is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application and website (collectively, the "Service").
By using the Service, you agree to the collection and use of information in accordance with this policy. Where the law or this policy calls for your consent, such as for biometric and consumer health data, we ask for it separately and don't treat using the Service as consent.
BIOMETRIC INFORMATION NOTICE
The Service collects body scan data and body measurements generated from device sensors (including LiDAR), photos taken during a scan (including photos in which the scanned person's face is visible), and face data derived from those photos: from app version 1.2, points around the eyes and other face data the iPhone records; until October 23, 2026, also facial landmarks and face geometry our servers derived (see "Face Photos and Facial Landmarks"). Such information may constitute "biometric information" or "biometric identifiers" under certain state laws, including the Illinois Biometric Information Privacy Act (BIPA), the Texas Capture or Use of Biometric Identifier Act, the Washington Biometric Privacy Law, the Colorado Privacy Act (biometric amendments effective July 2025), and the New York SHIELD Act.
This biometric data is used for two purposes only: to generate body measurements, 3D visualizations (including the face on the 3D model), transformation predictions, and related fitness or wellness insights for the person scanned and the account holder; and, as described in "Testing and Improving Our Software", to test and improve our own software, including training our own models, inside our company only. We train models on a scan only if the person scanned has agreed. Biometric data is never used to identify or recognize anyone, and faces are never compared with one another. See "Face Photos and Facial Landmarks" below for how face photos are handled.
Consent. From app version 1.2, before anyone is scanned for the first time, the app shows the person being scanned this notice, a summary of the retention policy below and how we use scans, and asks for their written consent: they confirm their name and tap Agree. They choose separately whether their scans may also be used for testing and training; saying no doesn't change the Service. A parent or legal guardian gives consent for a child under 18, and a child aged 13 to 17 is also asked to agree. When a trainer, a gym or a family member scans you, you give consent yourself, on the scanning phone; they can't give it for you. We record what was agreed, by whom and when, and we ask again if this notice changes in a way that matters.
Scans made with app versions before 1.2 were made without this screen. From version 1.2, each person is asked for consent at their next scan, and that consent covers their earlier scans. Until they agree, we use their earlier scans only to provide the Service to them (including fixing problems with their own scans), never to test or train our software.
Disclosure. We never sell, rent, lease or trade biometric data, and never use it for advertising. We disclose it only: to the people the person scanned chooses, and to the account holder who scanned them or a trainer they pair with; to the service providers that store and process it for us under contract (Amazon Web Services); when the law requires it, for example to answer a valid court order; or, with the consent given on the consent screen, to a company that acquires our business, which must keep following this policy. We never share it with another company for testing or training.
Biometric data is kept only for these purposes and on the schedule in the retention policy below.
RETENTION AND DESTRUCTION POLICY (Illinois BIPA, Colorado Privacy Act and other biometric laws)
What it covers. Every file of a body scan (the photos, including the face photos and the face data, the 3D model, the LiDAR depth and pose data, and the person outlines) and the measurements and estimates made from it, wherever we keep them: in the account, in our database backups, and in our test and training sets. We treat the whole scan as biometric data, even where a law might not.
Purposes. We keep biometric data only to provide the Service and, if the person scanned agreed, for the testing and training described in "Testing and Improving Our Software". At least once a year we review whether we still need it for these purposes.
When we destroy it. Biometric data is permanently destroyed at the earliest of these:
Deleting your account deletes your scans, including earlier (backup) versions of their files, and the scans filed under a phone that is linked only to your account. Deleted records are removed from our database backups within 35 days.
Test and training copies. When you delete a scan or your account, or withdraw your consent to testing and training, we stop using those scans for testing and training within 15 days, and we delete their copies in our test and training sets, on our servers and on our own computers, within 30 days. A test or training copy is never kept longer than the scan it came from. Values we learn for one person, such as how their own predictions compared with their later scans, are deleted with their account. A model we have already trained doesn't store the scans it learned from: it stores numbers adjusted using many scans together, and it can't be used to look up your scan or photos. We keep using models trained before your deletion and don't retrain them, but no model trained after that uses your scans.
Deleting your account does not delete:
If you are the person in such a copy or scan and want it deleted, ask the trainer, or email vtprivacy@visualizetechnologies.com, and we will delete it within 30 days and tell the account holder. Either way, these copies follow the 24-month limit above.
Legal exceptions. We keep data longer only when the law requires it: content reported to the National Center for Missing & Exploited Children is preserved for at least 90 days (see our Terms), and data covered by a court order or a legal hold is kept until that ends. We also keep a record of the consents given (who agreed, to what and when, but no scan images or face data) for 5 years after the scans it covers are deleted, to show that we had consent.
How we destroy it. We delete every stored copy and earlier version from our servers, our database backups, our test and training sets and our own computers, and we tell our service providers to delete theirs.
If there is a security incident. If we learn that biometric data may have been accessed or taken without authorization, we act at once to stop it and find out what happened and whose data was affected. We notify the people affected, and the regulators the law requires, without unreasonable delay: within 30 days after we determine that a breach occurred for Colorado residents, within 60 days under the FTC Health Breach Notification Rule, and sooner where another law requires it.
This policy is publicly available in compliance with 740 ILCS 14/15(a) and Colorado Revised Statutes § 6-1-1314. It was last reviewed on October 28, 2026.
Body scans capture the scanned person's face with the same camera as the rest of the body; there is no separate face photo step. The face also appears in some of the full-body photos and in the 3D model's texture. During the walk-around, the iPhone's built-in face detection looks for the face in the camera images, and the app keeps up to five photos in which the face is visible (none if no face is found), along with where the face is, which way it is turned and how clear it is in those photos and in other camera images it considered. This happens automatically in every body scan.
From app version 1.2: on iOS 26 or later, the app can also take full-resolution photos silently during the walk-around and keep close-ups cut from them: of the head and hair from several sides, of the hands, and of the whole body, plus up to four more close-ups of the face taken when the person faces the camera. For each of these photos, Apple's built-in Vision software on the iPhone records where the face is and how it is angled (turned, tilted up or down, and tilted sideways), points around each eye, the positions of the pupils, how open each eye is and a photo-quality score, and makes an outline of the person. The close-ups, the face data and the outlines are uploaded with the scan (see "Data Processing" below).
On our servers: today, no software on our servers looks for facial landmarks, no AI model retouches the face, and the servers don't rebuild the 3D shape of the face; the face on your 3D model comes from the model your iPhone builds. For scans from app version 1.2, our servers can use one face close-up and the face data the iPhone recorded to repaint the eyes on the 3D model, and the person outlines to correct the shape of the top of the head. This uses ordinary image-processing software, not AI models.
Scans processed until October 23, 2026 also went through steps we have since removed: software on our servers found facial landmarks (points such as the corners of the eyes and mouth) to pick the clearest face photo and check whether the eyes were open; an AI face-restoration model could retouch that photo, which then replaced the original, and retouched the face in the 3D model's texture; and the servers tried to rebuild the 3D shape of the face. Those landmarks were not kept, but a retouched photo or face texture made then stays with the scan.
We use scans to test and improve our own software, including to train our own models. For example, we run new versions of our scan processing on earlier scans to check that they work and to compare the results, and we may train models that make the 3D model, its texture (including the face), the measurements or the predictions more accurate.
What happens to these copies when you delete a scan or your account is described under "Biometric Data Retention and Destruction Policy".
Trainers, gyms and family members can scan other people with VZN. When you scan someone else:
Children.
Your data is stored securely using Amazon Web Services (AWS):
3D body scans and measurements are stored in encrypted cloud storage. Server processing runs on AWS: the processing servers accept no incoming connections from the internet, and access to stored scan files is logged.
When you capture a body scan:
Access to your data is managed as follows:
We do not sell your personal information. We may share data only in these circumstances:
You can pair with a personal trainer, or a trainer at your gym, by entering the pairing code they give you in the app. A trainer sees nothing from your account unless you pair with them, and our servers check that your pairing is active before sharing anything listed below with them.
A code you redeem on our website (visualizetechnologies.com/redeem) can also pair you. If the code came from a trainer, redeeming it connects you with that trainer as described in this section: they see the meals and workouts you log and can message you. The website shows you the trainer's name and asks you to confirm before it connects you.
If your trainer has an active VZN trainer or gym plan, you can use the VZN app free while you are paired ("companion access").
While a pairing is active, your trainer sees only:
Your trainer never sees:
Raw Apple Health readings are never shared with your trainer; values you choose to save to your profile, like your weight, can appear in the profile you share with them (see "Apple Health Data" below).
If you are the trainer, the same applies from your side: your paired clients see the scans you take of them, the plan and targets you set, and the notes you share with them, but never your private notes.
Either of you can end a pairing at any time. When a pairing ends, or if your trainer deletes their account, independent copies of the scans your trainer took of you and delivered to your account are saved to your account. The copies belong to you: you can keep viewing and downloading them, and they are deleted if you delete them or your account.
Once a pairing ends, our servers stop sharing your logged days, shared profile and notes with that trainer, and share links to the scans that trainer took of you stop working, whoever created them. Your chat history with that trainer stays readable to both of you. Your trainer keeps their own records, such as the scans they took of you, unless they delete them; to have those deleted, ask your trainer, or email vtprivacy@visualizetechnologies.com.
You can send a scan of yourself to another VZN account by entering their email address. Only scans of you, the account holder, can be sent this way, never a scan of a client or of a family member on your account. The person you send it to sees your name (or "A VZN user"), never your email address, and can accept or decline. If they accept, they get their own independent copy of the scan in their account. That copy is theirs: it stays in their account even if you later delete your original or your account.
You can create a web link to a scan you took, or to a scan a trainer took of you. A trainer can create one for a scan they took of you only while you are paired. A copy of a scan someone sent you can't be shared as a link. Anyone who has a link can open it in a web browser, without the VZN app or an account.
Anyone who has a link can view, save or pass on what it shows while it works, so share links only with people you trust.
The Service relies on the following third-party providers to operate. These providers may process limited data as necessary to deliver their services:
We do not share your personal data with analytics providers, advertising networks, or data brokers.
Our website includes a tag from an affiliate network, Impact (impact.com), meant to track affiliate links. Our website's security settings currently stop the tag from loading, so it doesn't run and Impact receives nothing from our website, and our website has no affiliate links. We will update this policy before we turn it on.
The support chat in the app (☰ → Settings & Support → Support Chat) is answered by an AI assistant, Anthropic's Claude, run through Amazon Bedrock on AWS, not by a person. The app asks for your consent before your first message. Its answers can be wrong; to reach a person, email vtsupport@visualizetechnologies.com.
The assistant receives what you type (the conversation so far, up to the last 20 messages) and account basics that help it answer: your user ID and display name, your plan and account status, your scan usage, and your gym organization ID if you have one. When you start a conversation, it also receives your app version, iOS version and device model, and whether the app crashed the last time you used it. It does not receive your email address or anything about the profiles on your account, such as clients. Whatever you type is sent, so don't type health details you don't want to share.
Conversations are stored on our servers and on your iPhone. The server copy is deleted when you delete your account.
To find and fix problems, the app uploads diagnostic information to our servers automatically. There is currently no setting to turn this off.
Who sees them: our team. A failed scan or crash report also creates an alert email to our team, which includes your name, email address, user ID, plan and gym ID with the problem details. The technical details of failed-scan and crash reports (not your name, email address or user ID) are sent to Anthropic's Claude through Amazon Bedrock to suggest a cause. Until spring 2026, these reports also became issues in our private GitHub repository (with user IDs and device and crash details, not names or email addresses), where an automated tool that runs on GitHub's servers could send an issue to Claude through Amazon Bedrock to suggest a fix; new reports no longer go there. Activity logs themselves are never sent to GitHub, to an AI model or by email.
How long they are kept: diagnostic logs and reports, and the GitHub issues and alert emails made from them, currently have no automatic time limit. Deleting your account deletes the logs and reports stored under your account (see "Account Deletion"), but not logs the app uploaded while you were signed out (filed under an ID for your device), the alert emails, or the GitHub issues. To have those deleted, email vtprivacy@visualizetechnologies.com and we will delete them within 30 days.
If you connect Apple Health (in the app: Settings → Health Data), the iPhone app reads steps, active energy, workouts, sleep, resting heart rate, weight, body fat, height, date of birth and biological sex. The iPhone app does not write to Apple Health.
The VZN Apple Watch app saves the workouts you record on it to Apple Health, and reads your heart rate and active energy while you record them, to show them live and in your workout summary.
How we use it: to personalize your own calorie and training targets, the Health view on your Apple Watch, and the score shown in progress videos of your own scans (in the Gallery). Apple Health data is used only for your own profile, never for a client's profile, screen, video or Watch view.
Where it is kept:
Apple Health data is never sold, never used for advertising or marketing, never shared with gyms or other third parties, and never stored in iCloud. Raw Apple Health readings are never shared with your trainer; values you choose to save to your profile, like your weight, can appear in the profile you share with them.
Turning it off and deleting it: to stop the app reading Apple Health, go to iPhone Settings → Privacy & Security → Health → VZN. To delete our copies, open Settings → Health Data in the app: turning off backup deletes the server copy, and "Disconnect Apple Health" deletes both the server copy and the copy on your iPhone. Deleting your account also deletes them.
Our Consumer Health Data Privacy Policy explains what consumer health data we collect (including body scans, measurements, body-composition estimates, Health & Safety answers such as pregnancy status, and Apple Health data), why, where it comes from, who we share it with, and how to use your rights. It is written for Washington's My Health My Data Act (RCW 19.373), Nevada's SB 370 and Connecticut's consumer health data law, and we apply it to everyone.
For all users: if there is a breach of your health information, we will notify you within 60 days, as the FTC Health Breach Notification Rule requires, and sooner where a state law requires it.
You have the right to:
To request a copy of your data, email vtprivacy@visualizetechnologies.com with your User ID (found in Support Info) and preferred format. Data export includes all body scans, 3D models, measurement history, and profile information.
You can delete your account in the app: open the ☰ menu, tap Account, tap Delete Account at the bottom, then confirm (Continue, then Delete Forever). You can also email vtprivacy@visualizetechnologies.com with subject "Account Deletion Request" and include your User ID and account email; we deactivate the account right away and delete your personal data within 30 days.
Deleting your account deletes your scans, including earlier (backup) versions of their files, and the scans filed under a phone that is linked only to your account. Deleted records are removed from our database backups within 35 days. Copies of your scans in our test and training sets are deleted within 30 days (see "Biometric Data Retention and Destruction Policy").
Deleting your account also deletes the diagnostic logs, crash reports and app-usage records stored under your account. It doesn't delete logs the app uploaded while you were signed out (filed under an ID for your device), or the alert emails and GitHub issues about your failed scans or crashes (see "Diagnostic Logs"). To have those deleted too, email vtprivacy@visualizetechnologies.com. We keep records of your subscription purchases as business records.
Two kinds of copies stay with other people: copies of your scans that someone else accepted are theirs, and scans a trainer took of you are part of that trainer's records. To have a trainer's scans of you deleted, ask the trainer, or email vtprivacy@visualizetechnologies.com.
Deleting your account also turns off the share links you created, links to your scans, and links to scans a trainer took of you. If you are a trainer, your paired clients keep independent copies of the scans you took of them (see "When a Pairing Ends" above).
We respond to requests within 45 days, and usually sooner. See "Your State Privacy Rights" below for who can make a request, how we verify it and how to appeal.
Accounts are only for adults 18 and older. By creating an account, you represent and warrant that you are at least 18 years old. We do not knowingly let anyone under 18 create an account or use the app themselves, and we may suspend or delete an account we find belongs to someone under 18.
An adult may scan a child under 18 only as described in "Scanning Other People and Children": as the child's parent or legal guardian, or with the parent's or guardian's consent on the consent screen. We treat children's data as sensitive data, and we never use children's scans for testing or training.
If you are a parent or guardian and believe your child has given us personal information, or was scanned without your consent, contact us at vtprivacy@visualizetechnologies.com and we will delete it.
Many states give their residents privacy rights, including California, Colorado, Connecticut, Delaware, Indiana, Iowa, Kentucky, Maryland, Minnesota, Montana, Nebraska, New Hampshire, New Jersey, Oregon, Rhode Island, Tennessee, Texas, Utah and Virginia; Alabama, Louisiana, Oklahoma and Vermont when their laws take effect; and Washington and Nevada for health data. Some of these laws apply only to larger companies. We offer the rights below to everyone, wherever they live.
Several states treat biometric data, health data, information about pregnancy, racial or ethnic origin, and data about children as sensitive data. We process sensitive data only with consent (from app version 1.2, through the consent screen; for a child, a parent's or guardian's consent) and only for the purposes in this policy. We never sell sensitive data. We don't use personal data to train large language models.
If we decline your request, in whole or in part, we'll tell you why. You can appeal by replying to our decision or by emailing vtprivacy@visualizetechnologies.com with the subject "Privacy Appeal". We'll respond in writing within 45 days, explaining what we did and why. If we deny your appeal, you can contact your state Attorney General, and our response will tell you how.
See also our Notice at Collection for California residents.
Under the Illinois Biometric Information Privacy Act, Texas's Capture or Use of Biometric Identifier Act, Washington's biometric identifiers law (RCW 19.375), the Colorado Privacy Act's biometric provisions and similar laws, you have the right to:
We treat a Global Privacy Control (GPC) signal as a request to opt out of the sale or sharing of personal information and of targeted advertising. We don't sell or share personal information or use it for targeted advertising, so there is nothing more to switch off.
To exercise any of these rights, contact us at vtprivacy@visualizetechnologies.com. We will not discriminate against you for exercising your privacy rights.
This notice tells California residents what personal information we collect and why, at or before the time we collect it. (The CCPA applies only to businesses above certain sizes; we give this notice to everyone.)
We don't sell or share personal information, including sensitive personal information, and haven't in the past 12 months. For the full details, including who receives personal information, see the rest of this policy.
In the event of a data breach that compromises your personal information, we will notify affected users as required by applicable state and federal law. All 50 states, the District of Columbia, and U.S. territories have data breach notification laws that we comply with.
We encrypt data at rest (AES-256) and in transit (TLS). Some state laws don't require a notice when stolen data was encrypted and the key wasn't taken; we don't rely on that to skip a notice we owe, and we notify whenever the law requires it.
We may update this Privacy Policy from time to time. We post the new Privacy Policy on this page with a new "Last updated" date, and we notify you of significant changes through the app or by email. We won't use personal information we already have in a materially different way from what this policy said when we collected it unless you agree, and we ask for consent again before we use biometric or consumer health data for a new purpose.
If you have questions about this Privacy Policy, please contact us:
