Hair Compass AI

Privacy Policy

Effective date: September 11, 2026

Hair Compass AI helps users track hair, scalp, routine, photo, lab, trigger, and procedure information for personal monitoring and clinician discussion support.

Information we collect

Depending on which features you use, Hair Compass AI may collect or store:

• Profile details you enter, such as hair goals, scalp sensitivity, and hair-loss context
• Hair and scalp check-in entries
• Routine, medication, supplement, procedure, lab, and trigger logs, which may include childbirth or other sensitive health context
• Photos you choose to capture or import
• Subscription and purchase status
• Optional Health data, including sleep, mindful sessions, heart-rate variability, resting heart rate, body mass, body mass index, and dietary protein

Health data

If you grant permission, Hair Compass AI reads selected HealthKit data from Apple Health to display context and compare it with your tracking history. If you separately enable cloud AI, selected health-derived values can be included in the tracking summary sent for your requested answer. Hair Compass AI does not write health data back to Apple Health. We do not use Health data for advertising or sell it.

Photos and camera

If you grant permission, Hair Compass AI can use the camera and photo library to capture, import, store, and display standardized scalp and hair images for progress tracking and comparison.

AI features

Hair Compass AI's AI features are optional and are not intended to provide medical advice, diagnosis, or treatment. They work in two ways:

• On your device. Daily insights run entirely on your iPhone (Apple Intelligence, where supported) and never leave it. Label text recognition also happens on your iPhone — though if cloud AI is on, the recognized text (not the photo) is sent for the summary, as described below.
• Cloud AI answers (opt-in). Ask Wren, record summaries, and ingredient explanations can use cloud AI after you agree in the app. Chat and record-summary requests can include check-in values, dates, treatment names and adherence, lab values, logged notes, and selected health-derived values, plus your questions, recent conversation, and selected earlier user messages from the same chat. Session memory is kept separately for each chat; a new chat does not inherit another chat’s conversation. Ingredient explanations send the recognized label text. Photos and profile contact fields are not attached to these text requests. Typed questions, notes, and label text may still contain identifying information; avoid including it.

Cloud text requests pass through our gateway hosted on Railway to DeepSeek for inference. Processing can occur outside your country. DeepSeek's Open Platform terms distinguish developer applications from its consumer services; its consumer privacy policy does not establish all processing rules for this app's users. We have not confirmed a fixed provider retention period, a no-training commitment, or an API-specific processing location for this deployment. Cloud Wren is a Beta feature and AI can make mistakes. Enable it only if you are comfortable sending the information described above under these disclosed processing uncertainties. You can decline or withdraw cloud consent in the app. We do not sell requests or use them for advertising. Declining cloud AI keeps model requests on your device where supported.

Gateway identity and retention

The gateway verifies an Apple-signed app transaction, device-key proof, and subscription transaction. It stores a pseudonymous account identifier, device public key, consent decisions, purchase/refund identifiers, and request counters to authenticate requests, enforce entitlements, and prevent abuse. Session tokens expire after fifteen minutes. Chat questions and answers are not written to the gateway database; local saved conversations remain on your iPhone. Network infrastructure and providers may process connection information such as IP addresses.

Consent, account, purchase, and anti-abuse metadata do not currently have a fixed automatic deletion period in the gateway service. Turning off cloud AI blocks new requests locally and records withdrawal on the gateway when reachable. Requests already received by a provider may finish; withdrawal cannot recall previously transmitted information. Contact us to request access, correction, or erasure of server-held information. Erasure may retain limited purchase and abuse-prevention records. Provider deletion may require a separate request, and deleting local records does not remove exported copies or automatically erase provider-held data.

Cosmetic preview testing

AI-generated cosmetic previews are separate from ordinary progress photos and text chat. Where enabled for reviewed test accounts, a separate consent flow uploads a selected photo to our gateway for an operator-reviewed illustration using OpenAI. Source and output image blobs are encrypted on the gateway. Unfinished jobs expire after one hour; accepted output has a twenty-four-hour recovery window. Purchase, credit, and attempt metadata can remain after image expiry. Generated previews are labelled illustrations, not evidence of regrowth or treatment results. Image access and credit purchases are not enabled for general customer use while privacy, backup, and quality checks remain open.

Subscriptions

An active Hair Compass Pro subscription is required for daily check-ins, care plans, trends, labs, progress photos, and AI features. Eligible new monthly subscribers can start with a three-day App Store free trial. Cloud AI remains a separate opt-in choice. Purchase processing is handled by Apple through StoreKit. We do not receive your full payment card information.

Affiliate links

Hair Compass AI may display affiliate links to non-medication physical products. If you open or purchase through these links, Hair Compass AI may earn a commission. These links are provided for convenience and are not medical recommendations.

How we use information

• Provide tracking and logging features
• Support progress review and comparisons
• Generate optional AI-powered summaries when you request them — on your device, or through the opt-in cloud AI described above
• Provide premium subscription functionality
• Improve app reliability and user support

Data sharing

We do not sell personal information. Data can be shared with Apple for purchases and beta distribution; Railway and the model provider for optional cloud requests; OpenAI and authorized reviewers for separately consented cosmetic-preview tests; and destinations you choose when exporting a report, sharing a photo, contacting support, or opening an affiliate link. TestFlight may provide Apple and the developer with beta feedback and diagnostic information under Apple's beta-testing controls. No third-party advertising or analytics SDK is included in the app.

Your choices

• Deny camera, photo, or Health permissions
• Decline cloud AI when asked, or turn it off at any time in the app (You → Baseline → Cloud AI)
• Avoid using AI-powered features entirely
• Choose not to use affiliate links
• Manage or cancel subscriptions through Apple
• Delete local records or saved chats, and contact us about server-held information
