Privacy Policy

Last updated: September 28, 2026

PlateLens is operated by VisionTech Solutions LLC, a Texas limited liability company ("we", "our", or "us"). We are committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile and signed-in web applications.

Summary: We collect data to provide personalized nutrition tracking. Your food photos are analyzed by AI, health data syncs from your device, and your information is stored securely in Firebase. We never sell your data. If you connect an AI assistant such as ChatGPT or Claude, it reads only the categories you authorize, only while you keep it connected, and nothing is sent to it on our initiative.

1. Information We Collect

1.1 Account Information

1.2 Health & Nutrition Data

1.3 Coach Conversations

1.4 Location Data

1.5 Device & Usage Data

1.6 Website Cookies & Analytics

This subsection describes analytics on the public platelens.app marketing and support website only. The rest of this policy covers the PlateLens mobile and signed-in web applications, except where a section expressly says otherwise.

1.7 Connected App Authorizations

If you connect PlateLens to an AI assistant (see section 5), we create an authorization record for that connection: the connecting application's registered identifier and name, the data categories you approved, the time of approval and of the latest use, a salted hash of the connection's access credentials (never the credentials themselves), and an opaque connection identifier you can use to revoke it. These records live in a separate authorization database from your nutrition data.

1.8 3D Body Scans

When you start a 3D body scan, phone placement, posture, environment checks and live capture guidance run on your device. After capture, the app sends the selected body images, enabled compatible camera depth, camera calibration, the height, weight and body model selected for that scan, and the capture evidence needed for validation to PlateLens’s own processing service on Google Cloud in the United States. This service runs our body-analysis models and geometric calculations to return the 3D result and estimated measurements. An authenticated connection checks that the request belongs to your active account.

Temporary calculation, explicit saving: the processing service uses request-specific temporary files and removes them when the request completes, fails or is cancelled. It does not create scan history or persist the camera images and raw depth in a database or image store. Body-scan inputs are not sent to OpenAI or another third-party AI inference service, and we do not use them to train models. Google Cloud provides the hosting infrastructure. A connection retry can resend the same captured images while the scan session remains open on your device.

Prepared results and saved scans: before returning an accepted result, the service temporarily stores its finished 3D shape and private reconstruction data in your account’s protected storage area. This does not create a history entry. An unsaved result expires after 24 hours and is removed by scheduled cleanup. Choosing Save scan retains those artifacts and adds estimated measurements, scan date, entered profile values, quality and method/version information to your history. Private reconstruction data lets our server reproduce the original geometry; it is not sent to the app, diagnostic ZIP or account export. The finished shape and original measurements are available through authenticated account access and data export. Camera images and raw depth are not stored with the result. Deleting the scan or account removes its shape, reconstruction data and record. Adding the scan’s entered weight to weight history is a separate optional action.

Optional diagnostics: if you enable diagnostic export, the service returns per-view analysis and fitting evidence for that request. Your phone combines it with original capture images, optional depth, camera information and local guidance/voice traces into a diagnostic ZIP. The ZIP is generated on your phone, can contain sensitive body images and measurements, and is shared only through a destination you choose. The server does not keep a diagnostic archive. Temporary phone copies and copies you explicitly save or share follow the handling described in the diagnostic export guide. A failed diagnostic export does not remove an accepted scan result.

1.9 PlateLens Emails

PlateLens sends emails about getting started, building the habit, getting back on track after a break, milestones and occasional news, from hello@updates.platelens.app to the email address of your PlateLens account. Which emails you receive, and when, is decided by PlateLens’s own backend on Google Firebase; we do not use a third-party marketing platform. To make that decision, it keeps a mailing profile with your account: details from your PlateLens profile (such as language, time zone, country, phone platform, goal and sign-up date), the days and times you log meals (not what you ate), when you last used the app or the web app, the emails already sent to you, and your email preferences and answers. An email can also include your name, your goal, your coach and your calorie and protein targets.

Delivery: emails are delivered by Amazon Simple Email Service (Amazon SES) in the United States, which receives your email address and the content of each email in order to deliver it. Links in our emails pass through click.platelens.app, the click tracking of Amazon SES, which tells us that a link was clicked; we keep only the time of your latest click, to judge whether some emails are still relevant to you. We do not track whether you open an email and do not record each delivery. Amazon SES also tells us when an email bounces permanently (the address cannot receive email) or is reported as spam, and we then stop emailing that address; a temporary delivery failure, such as a full mailbox, does not stop later emails.

Your choices: every email has an Unsubscribe link, supports one-click unsubscribe from your email app, and has a Preferences link to a page on mailing.platelens.app where, without signing in, you can stop or resume all PlateLens emails, receive them once a month or only at key moments of the year, or pause them for 3 months. Some emails ask an optional one-tap question; your answer is saved with your account and used only to adapt later emails. Unsubscribing does not affect your account or app notifications. The PlateLens emails guide explains each option.

Retention and deletion: the record of each email sent to you (which email, when, and whether it bounced permanently or was reported as spam) is kept for 90 days. Your mailing profile, preferences and answers are kept until you delete your account. Your account export includes your email preferences, your answers, the actions our team took on your email settings (which action and when) and that 90-day email history. Deleting your account deletes all of them. So that an address that unsubscribed, bounced permanently or reported spam is not emailed again, even after the account is deleted, we keep a keyed hash of that address, which is not the address itself and is not linked to any account. A keyed hash of an address that received an occasional announcement is kept for up to 14 months, so the same announcement is not sent to it twice. Amazon SES keeps addresses that bounced permanently or reported spam on its own suppression list. If a bounce, spam or click report cannot be processed right away, it is held, with the recipient address, for up to 4 days so it can be processed again. A scheduled email task can hold a copy of your mailing profile, without your email address, until the task is completed or cancelled, which is usually shortly after its scheduled time. If sending is delayed (for example by a large backlog of emails, retries or a service outage), the task is kept longer, for at most 31 days after it was created, when Google Cloud Tasks deletes it.

3. Third-Party Services

We use the following third-party services to operate PlateLens:

4. AI Data Processing & Third-Party AI Disclosure

Important: PlateLens uses third-party AI services to provide core functionality. By using AI-powered features, you consent to this data processing.

We use OpenAI (OpenAI, L.L.C., San Francisco, CA, USA) to power the following features:

For more information, review OpenAI's Privacy Policy and Enterprise Privacy documentation.

5. Connected Apps (MCP Connector)

PlateLens offers an optional, read-only connection for AI assistants that support the Model Context Protocol (MCP), such as OpenAI's ChatGPT and Anthropic's Claude. Nothing in this section happens unless you explicitly connect an assistant. The PlateLens mobile app does not use this connection, and the connector is never used for advertising.

How a connection is established

You start the connection from the assistant. It sends you to auth.platelens.app, where you sign in with the same Google or Apple account you use in PlateLens and approve, category by category, what that assistant may read. Your identity is derived solely from that sign-in: a connection cannot be pointed at another account, and no part of the connector accepts an account identifier, email address or file path as input.

What a connected assistant can read

A connected assistant can never read meal or progress photos, audio, private notes, coach conversations, your email address, your internal account identifier, payment or subscription details, GPS coordinates, street address, or device identifiers, and it cannot create, edit or delete anything in your account.

Why we process it

We process these categories only to answer the specific read request that the assistant makes on your behalf during your conversation. Reads never trigger AI analysis, exports, translations or background jobs, and they are logged only as described under "Retention".

Where the data goes

The result of each read is returned to the assistant you connected. From that moment it is handled by that assistant's provider under its own terms and privacy policy — for example OpenAI for ChatGPT, or Anthropic for Claude — and may be stored in your conversation history there. Depending on your settings with that provider, it may also be used to improve its models (for example, ChatGPT's "Improve the model for everyone" setting). These providers are independent data controllers, not our processors. PlateLens does not send your data to any assistant on its own initiative.

Retention

Revoking and deleting

Revoke any connection at any time in the PlateLens app under More → Preferences → Connected Apps, or at auth.platelens.app. Revocation is enforced on the assistant's very next request, including before any credential renewal, and disconnecting an assistant never affects your PlateLens sign-in. You can also remove PlateLens from the assistant's own settings. Requesting deletion of your PlateLens account immediately revokes every connection, and the final erasure deletes the authorization records.

Service providers for this feature

The connector runs on Google Cloud (Cloud Run, Firestore and Secret Manager, United States), sign-in uses Firebase Authentication, and Cloudflare provides the network edge (TLS, proxying and abuse protection using hashed network identifiers). See section 3.

Legal basis and more information

Your explicit, category-by-category authorization is the legal basis for every read; you withdraw it by revoking the connection. Technical details, the full list of what can and cannot be read, and connection instructions are published at platelens.app/mcp.

6. Data Retention

7. Your Rights

You have the right to:

8. Data Security

We implement industry-standard security measures:

9. Children's Privacy

PlateLens is not intended for users under 13 years of age. We do not knowingly collect personal information from children. If you believe we have collected data from a child, please contact us immediately.

10. International Data Transfers

Your data may be processed in the United States where our servers are located. By using PlateLens, you consent to this transfer. We ensure appropriate safeguards are in place for international data transfers.

11. California Privacy Rights (CCPA)

If you are a California resident, you have additional rights under the California Consumer Privacy Act (CCPA):

We do not sell your personal information for money, and we never use the personal information inside your PlateLens account for advertising. If you arrive from an advertisement we run inside ChatGPT, we share a pseudonymous advertising identifier with OpenAI so that we can measure whether that advertisement led to a download, and OpenAI may also use it for its own purposes; under California law this may count as “sharing” for cross-context behavioral advertising. If you connect an AI assistant through Connected Apps, the data it reads is disclosed to that assistant's provider at your direction, as described in section 5; that is not a sale.

To opt out (Do Not Sell or Share My Personal Information): send a Global Privacy Control signal from your browser — we honour it automatically and load nothing — or block cookies for this site.

To exercise your California privacy rights, contact us at privacy@platelens.app or use the in-app deletion feature.

12. Legal Basis for Processing (GDPR)

If you are located in the European Economic Area (EEA), United Kingdom, or Switzerland, we process your personal data based on the following legal grounds:

Processing Activity Legal Basis
Account creation and authentication Contract performance
Food photo analysis and nutrition tracking Contract performance

You may withdraw your consent at any time by adjusting your app settings or contacting us.

13. Health Data Protection

We take special care with health and fitness data collected through Apple HealthKit and Google Health Connect:

Prohibited Uses: Health and fitness data is never used for:

Health data is only used to provide you with personalized nutrition tracking and wellness insights within the app.

If you connect an AI assistant through Connected Apps (section 5), health and nutrition data is shared with it only within the categories you approved, only on that assistant's request, and never with photos, notes or conversations. The prohibited uses above continue to apply to us; the assistant's own use is governed by its provider's policy.

14. Changes to This Policy

We may update this Privacy Policy periodically. We will notify you of significant changes via in-app notification or email. Continued use after changes constitutes acceptance of the updated policy.

15. Contact Us
