Smile.Health ("we," "our," "us") respects your privacy. This Privacy Policy explains what information we collect, how we use it, and the choices you have. By using the Smile.Health app, you agree to the practices described here.
1. Information We Collect
Account information. When you create an account, we may collect your name, email address, and login credentials.
Health & habit data. To provide the app's core features, we collect information you log yourself, including:
- Brushing and flossing check-ins
- Hygiene timer usage
- Dentist check-up records and self-reported gum sensitivity
- Goals (e.g., teeth whitening) and reminder preferences
- Your Smile Glow Score and related risk estimates, calculated from the habits you log
This information is health-related and is treated with additional care. We do not sell this data.
Photos. If you use the Photo Timeline feature, we collect the progress photos you take or upload. Photos are used solely to show your smile's progress over time and to power photo-based analysis features in the app.
Purchase information. Smile.Health offers auto-renewable subscriptions. Purchases are processed by Apple's App Store and managed through RevenueCat, our subscription management provider. RevenueCat receives your purchase history, subscription status, and an anonymized user identifier in order to validate purchases, manage entitlements, and keep your subscription status in sync across devices. RevenueCat does not receive your payment card details — those are handled directly by Apple. Learn more at RevenueCat's privacy policy.
Usage & analytics data. We use PostHog to understand how people use Smile.Health — for example, which onboarding steps are completed, where users drop off, and which features are used most. Data collected may include app interactions and screen views, device information, anonymized or pseudonymous identifiers, and general usage patterns. We do not use this data to build advertising profiles, and we do not sell it. Learn more at PostHog's privacy policy.
Diagnostic information. We may collect crash logs and performance data to help us fix bugs and improve stability.
2. How We Use Your Information
- Provide, maintain, and improve the app's features
- Calculate your Smile Glow Score and risk estimates
- Process and manage your subscription
- Understand onboarding drop-off and improve the user experience
- Generate reports (such as the Dentist Report) that you choose to create or share
- Communicate with you about your account or app updates
- Diagnose technical issues and maintain app security
3. How We Share Your Information
We do not sell your personal data. We share information only with:
- Apple, to process purchases through the App Store
- RevenueCat, to manage subscription entitlements
- PostHog, to analyze app usage and improve onboarding
- Service providers who help us operate the app (e.g., hosting, infrastructure), bound by confidentiality obligations
- Law enforcement or regulators, only where required by law
If you generate and share a Dentist Report, it is shared only when and how you choose to share it (e.g., exporting or sending it yourself).
4. Your Choices
- Access and deletion. You can request a copy of your data or ask us to delete your account and associated data by contacting us at the email below.
- Photos. You can delete individual progress photos at any time within the app.
- Subscriptions. You can manage or cancel your subscription at any time through your Apple ID account settings.
- Analytics. To request that your usage data be excluded from analytics, contact us at the email below.
5. Data Retention
We retain your information for as long as your account is active or as needed to provide the app's features. If you delete your account, we will delete or anonymize your personal data within 30 days, except where we are required to retain it for legal or accounting purposes.
6. Children's Privacy
Smile.Health is not directed at children under 13 (or the relevant age of digital consent in your region), and we do not knowingly collect personal information from children without appropriate consent. If you believe a child has provided us with personal information, please contact us so we can remove it.
7. Data Security
We use reasonable technical and organizational measures to protect your information. However, no method of transmission or storage is 100% secure, and we cannot guarantee absolute security.
8. International Data Transfers
Your information may be processed in countries other than your own, including the United States, where our service providers (including RevenueCat and PostHog) operate. We take steps to ensure appropriate safeguards are in place for such transfers.
9. Changes to This Policy
We may update this Privacy Policy from time to time. Material changes will be reflected by updating the "Last updated" date above, and where required, we will notify you through the app or by other means.
