Biometric Data Policy

Last updated: June 2026

This Biometric Data Policy supplements our Privacy Policy and Terms and Conditions. It describes in detail how See Stella Pty Ltd (ACN 669 216 924) collects, processes, retains, and deletes biometric information obtained when you use the Stella facial scanning feature.

1. What Counts as "Biometric Data" at Stella?

At Stella, Biometric Data refers to:

  • High-resolution facial photographs captured via the in-app camera.
  • Derived facial-skin metrics — for example, wrinkle depth, redness index, pore visibility, and pigmentation maps — computed from those photographs.

Where Stella creates de-identified, aggregated datasets from multiple users such that individuals are no longer reasonably identifiable, Stella intends to treat those datasets as separate from individual Biometric Data. Individual skin metrics, facial photographs and other Biometric Data remain protected under this Policy and are never sold. How Stella uses de-identified, aggregated datasets is described in our Privacy Policy.

What we do not collect. We do not collect video, depth data, or background imagery — only the still selfie you take to request a scan. We do not collect full 3-D face geometry, and we do not create a biometric template or "faceprint." We never use your face to recognise, identify, or authenticate you: your account is secured by email and password only. Stella's scans are used exclusively for appearance-level skin analysis, never for identity verification.

2. Why We Collect Biometric Data

We collect and process Biometric Data only for the following purposes:

To Generate Skin Insights

Analyse facial metrics to provide you with personalised cosmetic and wellness observations, tracked over time.

User Experience

Display your scan history and progress so you can see how your skin metrics change in response to your routine, lifestyle, and environment.

Product Improvement

Train and validate our AI skin-analysis models using aggregated or de-identified data where feasible, to improve measurement accuracy for all users.

Security & Fraud Prevention

Detect spoofed, reused, or fraudulently submitted images to maintain the integrity of your personal skin data.

We do not use Biometric Data for advertising outside the Stella ecosystem, nor do we sell, rent, or licence it to any third party.

3. Consent

We obtain explicit, informed opt-in consent before your first facial scan. The consent screen explains:

  • What Biometric Data we capture and how it is processed.
  • Why we collect it and how it benefits you.
  • Our retention schedule and how to request deletion.
  • How to withdraw consent at any time.

You must tap "I Consent" to proceed. Consent can be withdrawn at any time by deleting your account or emailing privacy@seestella.co.

Without consent, scanning features will be unavailable, but you can still browse content and use other non-biometric features of the app.

4. Retention Schedule

We retain Biometric Data for the minimum time necessary to deliver our services.

Data TypeRetention PeriodDeletion Method
Raw facial photographs3 years from date of captureSecure deletion from primary storage; cryptographic erasure applied to backups
Derived biometric metrics (skin scores, analysis data)Up to 3 years from your last account activity, or until you delete your accountSecure deletion; de-identified, aggregated data may be retained and used for research, product improvement and other purposes described in our Privacy Policy

When you delete your account, all of your facial photographs and derived biometric metrics are deleted within 30 days. If you withdraw consent or request early deletion of specific data, we complete the process within the same 30-day period.

5. State-Specific Requirements (USA)

Illinois (BIPA)

If you are an Illinois resident, we collect Biometric Data only with your prior written consent. We do not profit from your Biometric Data. You may request deletion within 30 days. Our full BIPA-compliant retention schedule is available on request at privacy@seestella.co.

Texas (CUBI Act)

If you are a Texas resident, we will not sell your Biometric Data and will destroy it within a reasonable time after the purpose for which it was collected has been satisfied, or within 3 years of your last interaction — whichever is first.

Washington (WA MHMD) & Other CHD States

Biometric Data constitutes Consumer Health Data under the Washington My Health My Data Act and equivalent state laws. Your rights and our obligations in those states are detailed in Section 6 of our Terms and Conditions and our Privacy Policy.

6. Security Measures

We apply the following technical and organisational controls to protect Biometric Data:

  • Encryption at rest: AES-256 encryption on all stored data.
  • Encryption in transit: TLS 1.2+ for all data transmitted between your device and our servers.
  • Network isolation: Production systems are network-isolated; access requires multi-factor authentication for all privileged roles.
  • Access controls: Only personnel with a documented need-to-know role may access identifiable Biometric Data; all access is logged and periodically reviewed.
  • Infrastructure certifications: Our cloud provider (Google Cloud Platform) holds SOC 2 Type II, ISO 27001, and IRAP PROTECTED certifications.
  • Incident response: We maintain a documented breach-response plan and will notify affected users and regulators within 72 hours of confirming a breach likely to cause serious harm.

7. Sharing & Disclosure

We share Biometric Data only with the limited service providers described below. Each acts strictly on our written instructions, under contract, and is prohibited from using your data for its own purposes.

Cloud hosting — Google Cloud Platform (United States)

Your facial photographs and derived metrics are stored with Google Cloud Platform in a data centre located in the United States, which hosts this data on our behalf so we can deliver your scan history and progress over time. Google Cloud stores this data for the periods set out in Section 4 above, under the security controls in Section 6 (including AES-256 encryption at rest), and deletes it on the same schedule. Google Cloud holds SOC 2 Type II, ISO 27001, and IRAP certifications and is contractually barred from accessing or using your data for its own purposes.

AI analysis provider — OpenAI

To generate your skin metrics, your facial photograph is sent to OpenAI, a third-party AI provider that analyses the image and returns the derived measurements. OpenAI processes your image solely to perform this analysis, on our instructions and under contract. OpenAI retains your image for up to 30 days, solely to monitor for safety and abuse, after which it is permanently deleted. The 30-day window is OpenAI's standard period for detecting misuse. OpenAI does not use your image to train its models, and is contractually prohibited from any other use or disclosure.

Legal requirements

We may disclose Biometric Data when legally compelled by a valid court order, law enforcement request, or regulatory obligation.

We never sell, rent, or licence Biometric Data to any third party. We never share it with advertisers or data brokers.

8. Your Rights

Access & Download

Request a copy of your Biometric Data in a machine-readable format (JSON or CSV) by contacting privacy@seestella.co.

Deletion

Delete individual scans or your entire history at any time by emailing us. Deletion is completed within 30 days.

Withdraw Consent

Disable future scans at any time in app settings. No further Biometric Data will be collected from that point. Existing data is retained per the schedule in Section 4, unless you also request deletion.
