This Privacy Policy explains how Trichometrics ("we", "us", or "our") collects, uses, shares, retains, and deletes information when you use the Trichometrics mobile application and related services (the "App"). For a privacy request, contact support@trichometrics.com.
This Policy applies when you create or use an account, capture or select photos, request an AI-powered hair or scalp analysis, use guided capture or transplant-related features, track treatments and progress, make a purchase, receive reminders, or contact support.
We collect information you provide directly:
We and our service providers also collect:
The App uses the AI API provided by Anthropic, PBC ("Anthropic") as a third-party service to generate hair and scalp analyses. Depending on the feature you choose, the request sent to Anthropic may contain:
We do not include your name, email address, password, or Trichometrics account identifier in the Anthropic AI request. Anthropic receives the request solely to generate the analysis you asked for. The resulting analysis is returned to our backend and may be stored in your account history.
Under Anthropic's standard commercial API practices, API inputs and outputs are not used to train its generative models by default. Anthropic may retain API inputs and outputs for up to 30 days under its standard API retention period. Limited exceptions may apply, including longer retention required for trust and safety enforcement, legal compliance, or a different retention arrangement or feature that applies to our account. See Anthropic's privacy policy and Anthropic's privacy center.
For this Policy, "Face Data" includes a photo containing a face and temporary information derived from a face, such as face bounds, eye landmarks, and head pose.
The App may process temporary face bounds, eye landmarks, head yaw/pitch/roll, framing, sharpness, brightness, and derived hairline or density measurements on your device. This processing guides head positioning, verifies that a usable hair or scalp view is present, and calculates hairline or density measurements.
Face bounds, eye landmarks, and head-pose values are not stored in your account and are not sent to Anthropic, PostHog, or RevenueCat. They are held temporarily in memory and discarded after the capture or processing session. Derived hairline and density measurements may be sent to Anthropic as described in Section 3.
Photos containing a face may be transmitted to Supabase for backend processing or storage and to Anthropic for the requested AI analysis. We do not use Face Data for facial recognition, identity matching, authentication, advertising, marketing, biometric-profile creation, or identifying an anonymous person. We do not sell Face Data or share it with advertising platforms, data brokers, or information resellers.
Before the App collects or uses Face Data for guided capture, and before it sends photos or related context to Anthropic, the App presents a disclosure identifying the data, recipient, and purpose and asks for your affirmative consent. If you decline, the App does not perform the AI analysis or send the disclosed data to Anthropic.
You can withdraw AI data-sharing consent at any time through Profile → App Settings → AI Data Sharing → Withdraw Consent. Withdrawal stops future Face Data processing for guided capture and future transfers to Anthropic unless you consent again. Withdrawal does not automatically delete photos, results, or other data already stored in your account or data already processed by a provider. Use the deletion controls described in Section 9 or contact support to request deletion.
We do not repurpose personal information or Face Data for a materially different purpose without obtaining additional consent where required.
We do not sell or rent personal information. We share information only as needed for these purposes:
We require every third party with whom we share user data, including Face Data, to provide the same or equal protection of that data as stated in this Policy and required by applicable platform rules; to process it only for the authorized, limited purpose; and to apply appropriate retention, deletion, confidentiality, and security safeguards. If a provider cannot meet those requirements, we will not share the data with that provider.
Account data, photos, and results may be stored using Supabase infrastructure. We use administrative and technical safeguards designed to protect information, including encrypted transmission, authentication, access controls, and restricted service credentials. No storage or transmission method is completely secure, and we cannot guarantee absolute security.
Information may be processed in countries where our providers operate, including the United States and European Union, subject to contractual and legal safeguards.
You may initiate deletion of individual photos from the App where that control is available. You may initiate account and associated-data deletion through Profile, or request assistance at support@trichometrics.com. Because deletion requires backend processing, contact us if an in-App deletion does not complete so we can verify and process the request. Completion may not be immediate. Limited records or copies may remain where reasonably necessary for legal compliance, security, fraud prevention, dispute resolution, technical recovery, or backup-retention cycles, and are deleted or de-identified when the applicable reason or retention cycle ends.
Deleting data from Trichometrics does not shorten data already within a provider's permitted retention window, but we require providers to delete or de-identify it according to their applicable obligations and retention terms.
Depending on your location, you may have rights to access, correct, receive, object to processing of, restrict processing of, or delete personal information. You can update profile fields, manage notifications, withdraw AI data-sharing consent, delete available content, or initiate account deletion in the App. You may also contact support@trichometrics.com.
Trichometrics is not intended for children under 13, or the higher minimum age required in a user's jurisdiction. We do not knowingly collect personal information from children below the applicable minimum age. Contact us if you believe a child has provided information.
We may update this Policy. If a change materially expands how previously collected information is used or shared, we will provide notice and request additional consent where required. The date above identifies the latest version.
