Privacy Policy

Last updated: May 4, 2026

This Privacy Policy explains how Smile ("we", "us", or "our") collects, uses, and protects information in connection with the Smile mobile application (the "App") and our website (the "Site"), together the "Services." We've designed Smile to collect only the information needed to make the App work well and personalize your experience. This document describes what that means in practice.

Information You Provide

When you use the App, we collect information you provide directly during onboarding and ongoing use, including:

• Account information: If you sign in with Apple or Google, we receive a unique identifier and (depending on your selections) your name and email. You may also choose to skip account creation and use the App anonymously.
• Onboarding inputs: Your name, age range, gender identification, brushing habits, goals, preferred voice style, and morning/evening brush times. These are used to personalize your routine and content.
• Smile Scan: A selfie image you choose to capture during onboarding. The image is processed locally on your device using Apple's Vision framework to detect a face and smile, then stored on our servers and associated with your account. The scan is used solely to generate a personalization score; it is not analyzed for medical or dental purposes.
• Commitment signature: A drawn signature image captured during onboarding to mark your commitment to the habit.
• Settings and preferences: Your content type toggles for morning and evening, notification preferences, and dark mode setting.

Information Collected Automatically

When you use the App, we collect information automatically about how you interact with it:

• Brushing session data: When each session started and ended, duration, whether you completed the full two minutes, which content piece played, and which voice style was used.
• Streak and stats: Computed from your session history.
• Diagnostic data: Anonymous performance and crash data to help us identify and fix bugs.
• Analytics events: We use PostHog to track anonymized product usage events, such as which onboarding screens you viewed, when you started a session, and when you reached streak milestones. These events help us improve the App.

How We Use Information

• To provide and personalize the App's features, including selecting content for your sessions and computing your Smile Factors;
• To send you notifications you've opted into (Morning Nudge, Evening Nudge, Streak Protection);
• To process and manage your subscription;
• To improve the App through aggregated, anonymized analytics;
• To respond to your support requests;
• To comply with legal obligations.

Service Providers

We rely on third-party service providers to operate Smile. These providers process information on our behalf under contractual privacy obligations:

• Supabase — hosts our database and stores your account data, smile scan image, and brushing session history.
• RevenueCat — processes your subscription and trial. They receive a customer identifier and subscription metadata.
• Apple App Store / Google Sign-In — handle authentication when you use those sign-in methods.
• PostHog — captures anonymized product analytics events.
• ElevenLabs and Anthropic — power our content generation pipeline. These providers do not receive your personal information; they generate the audio and text content that the App later plays to you.
• NewsAPI.ai — supplies news headlines for our daily news content. They do not receive your personal information.

Information We Do Not Collect

We do not sell your personal information. We do not share your data with advertisers. We do not track you across other apps or websites for advertising purposes. The Smile Scan is not used for medical or dental analysis, and we do not claim to diagnose any condition.

Children's Privacy

The App is not directed to children under the age of 13, and we do not knowingly collect personal information from children under 13. Onboarding requires users to confirm they are 13 or older. If you believe a child under 13 has provided us with information, contact us at the email below and we will delete it.

Your Rights

You have the right to access, correct, or delete the personal information we hold about you. You can:

• Edit your preferences and brush times in the App's Profile tab at any time;
• Delete your account from Profile → Account → Delete Account, which will permanently remove your account, smile scan, and session history;
• Manage your subscription in Profile → Manage Subscription or directly through your iOS subscription settings;
• Contact us at the email below to request access to your data or to make any other privacy request.

If you reside in California, the European Economic Area, the United Kingdom, or another jurisdiction with applicable privacy laws, you may have additional rights, including the right to data portability and the right to lodge a complaint with a supervisory authority.

Data Retention

We retain your account information and brushing history for as long as your account is active. When you delete your account, we delete your personal data within 30 days, except where retention is required for legal, accounting, or fraud-prevention purposes.

Security

We take reasonable technical and organizational measures to protect your information, including encryption in transit and at rest. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

Changes to This Policy

We may update this Privacy Policy from time to time. When we do, we will revise the "Last updated" date above. Material changes will be communicated through the App or the Site. Your continued use of the Services after changes take effect constitutes acceptance of the updated policy.
