Privacy Policy
ZENITH ("we", "our", or "us") operates the ZENITH mobile application (the "App"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our App. Please read this policy carefully. If you disagree with its terms, please stop using the App.
Personal Information You Provide:
- Name and email address (via Sign in with Apple)
- Age
- Health and wellness data: skin condition self-assessments, sleep hours, water intake, energy levels, workout logs
- Progress photos you voluntarily upload
- Goals and focus areas
- Usage preferences and app settings
Information Collected Automatically:
- Device information (iOS version, device model, unique device identifiers)
- App usage data (screens viewed, features used, session duration)
- Crash reports and performance data via Sentry
- Push notification tokens
Information From Third Parties:
- Authentication data from Apple (name, email, unique ID)
- Subscription status from RevenueCat
- Analytics data via PostHog
- To provide and personalize the App's features and your ZENITH program
- To calculate and display your progress scores
- To power the AI coaching features via OpenRouter
- To enforce fair usage limits (Coach messages, progress photos) shown in the App
- To send push notifications (with your permission)
- To process subscription payments via RevenueCat
- To improve the App through analytics
- To comply with legal obligations
All personal data is stored in Supabase, which uses industry-standard AES-256 encryption at rest and TLS 1.2+ in transit. Authentication tokens are stored in iOS Keychain via expo-secure-store. We never store your Apple ID credentials — only the authentication tokens provided by Apple. Progress photos are stored in Supabase Storage with private access policies. We implement Row Level Security (RLS) ensuring you can only access your own data.
When you open a Shop product link, the retailer (including Amazon) may collect data under its own privacy policy. ZENITH does not receive your Amazon account or payment details from those visits.
The wellness data you enter in ZENITH (skin ratings, sleep, exercise) is treated as sensitive health information. We do not sell this data to third parties. We do not share this data with insurance companies, employers, or healthcare providers. This data is used solely to provide you with personalized coaching within the App.
You have the right to:
- Access your personal data (export available in Account settings)
- Correct inaccurate data (edit profile at any time)
- Delete your data (Delete Account in Settings removes all data within 30 days)
- Withdraw consent for analytics (disable in Settings > Security)
- Lodge a complaint with your local data protection authority
Active accounts: data retained while account is active.
Deleted accounts: all personal data deleted within 30 days, except data required for legal compliance (transaction records retained 7 years per tax law).
Anonymized, aggregated analytics may be retained indefinitely.
ZENITH is not intended for users under 13 years of age. We do not knowingly collect data from children under 13. If we discover we have collected such data, we will delete it immediately.
We will notify users of material changes via push notification and in-app notice at least 7 days before changes take effect.
If you use Sign in with Apple, Apple may provide us with a unique identifier and, on first sign-in only, your name and email (or a private relay email). You can manage Apple ID permissions in iOS Settings.
Subscriptions and refunds are processed by Apple. We do not receive your full payment card number. Purchase history is available in your Apple ID account.
ZENITH is available on the Apple App Store (App ID 6776723661, SKU ZENITH-IOS-001). ZENITH may request permission to send push notifications, access the camera and photo library (for progress photos), and use on-device storage. You may revoke permissions in iOS Settings at any time.
ZENITH's App Store privacy labels describe our analytics and usage data practices. We collect this information only to measure and improve the App — not to sell your data or serve third-party advertising. You can disable usage analytics in Settings > Security.
We use PostHog for first-party product analytics (screens viewed, features used, session duration) tied to a pseudonymous user ID — not your name or email unless you sign in.
ZENITH does not sell personal information, does not share health or progress data with ad networks, and does not use your data for cross-app advertising or data-broker purposes.
Apple's "tracking" label refers to linking your data across other companies' apps and websites for advertising. We use analytics only to improve ZENITH. You can turn off usage analytics anytime in Settings > Security.
Messages you send to the AI Coach are transmitted to OpenRouter and underlying model providers to generate responses. Do not submit sensitive personal data you do not want processed by AI vendors. AI output is automated and may be inaccurate — it is not medical or professional advice.
California residents may request to know, correct, delete, and opt out of the sale or sharing of personal information. We do not sell personal information. To exercise rights, email thezenithappsupport@gmail.com with "California Privacy Request". We will verify your request and respond within 45 days as required by law.
If you are in the EEA, UK, or Switzerland, our legal bases for processing include contract performance (providing the App), legitimate interests (security, analytics, improvement), and consent (notifications, optional features). You may request access, rectification, erasure, restriction, portability, and objection by contacting thezenithappsupport@gmail.com. You may lodge a complaint with your local supervisory authority.
Your data may be processed in the United States and other countries where our service providers operate. We rely on appropriate safeguards such as standard contractual clauses where required.
If we become aware of a breach affecting your personal data, we will notify affected users and regulators as required by applicable law.
