Privacy Policy

Overview

Luma Smile is an iOS app for oral-care habit tracking, private progress photos, dentist appointment reminders, product logging, and optional AI-assisted product summaries. This Privacy Policy explains what information is processed when you use the app, the website, subscriptions, support, and AI product evaluation.

Luma Smile is designed to keep routine tracking data on your device whenever possible. We do not sell your personal information, and we do not use your progress photos, dental routine history, or product logs for advertising.

Who is responsible

Luma Smile is provided by the developer identified in the App Store listing for the app. For privacy questions, requests, or concerns, contact futureyou.support@gmail.com.

Information stored on your device

The app may store the following information locally on your iPhone or in Apple-managed device backups, depending on your iOS settings:

• Routine completions, streaks, routine score, and brushing timer preferences.
• Enabled habits such as morning brushing, midday brushing, evening brushing, flossing, mouthwash, and progress photos.
• Notification preferences, including reminder times and whether routine reminders are enabled.
• Dentist appointment dates, practice names, notes, and reminder choices.
• Progress photos and product photos that you choose to save in the app.
• Product entries, including product name, brand, notes, AI score, AI summary, and AI recommendation.

This information is intended to remain local unless you choose a feature that sends information to a server, such as AI product evaluation, support email, subscriptions, or standard website access.

Photos and health-related information

Progress photos and notes about your oral-care routine may reveal sensitive information about your mouth, teeth, dental habits, or health concerns. Luma Smile is not a medical records system and is not intended for emergency care, diagnosis, or treatment. Avoid adding information that you do not want stored on your device or included in a product evaluation request.

Progress photos are stored locally by the app. Product photos are stored locally unless you choose to include a product photo in an AI product evaluation request. When you do, the product photo is sent to our API so visible packaging, claims, ingredients, and warnings can be reviewed for the generated summary.

AI product evaluation

If you request an AI product evaluation, the app sends the product name, brand, notes, and optional product photo to a Luma Smile API endpoint. The API uses OpenAI services to generate a score, summary, and recommendation. The AI request is limited to the product information needed for the evaluation.

AI responses are informational only and may be inaccurate, incomplete, or unsuitable for your specific dental needs. Do not include sensitive medical details in product notes or product photos. For pain, sensitivity, gum issues, whitening concerns, medication interactions, or any dental condition, consult a dentist or qualified healthcare professional.

Subscriptions and purchases

Luma Smile may offer paid subscriptions or premium access through Apple in-app purchases. Purchases are processed by Apple. We use RevenueCat to manage subscription status, restore purchases, and unlock paid features. Apple and RevenueCat may process purchase identifiers, receipt information, product identifiers, entitlement status, transaction history, country or storefront information, and technical identifiers needed to operate purchases and prevent fraud.

We do not receive your full payment card number from Apple. Subscription management, cancellations, refunds, and billing issues are handled through your Apple account and the App Store.

Notifications

If you allow notifications, Luma Smile schedules local reminders on your device for routines, progress photos, and dentist appointments. Notification permission is managed by iOS. You can change notification settings in the app or in iOS Settings. Routine notification content is not used for advertising.

Support and communications

If you contact support, we process the information you choose to send, such as your email address, message, screenshots, device model, iOS version, app version, and other troubleshooting details. Please do not send sensitive dental or medical information unless it is necessary for your support request.

Website data

When you visit the Luma Smile website, the hosting provider may process technical information such as IP address, browser type, device information, requested pages, timestamps, referring URLs, and server logs. We use this information to operate, secure, debug, and improve the website. The website is not intended to collect dental routine data.

How we use information

We process information for the following purposes:

• Provide app features such as routine tracking, progress photos, reminders, product logs, and dentist planning.
• Generate optional AI product evaluations when you request them.
• Operate subscriptions, premium access, restore purchases, and fraud prevention.
• Respond to support requests and diagnose technical issues.
• Maintain app and website security, reliability, and legal compliance.
• Develop and improve Luma Smile without selling personal information or using it for behavioral advertising.

Legal bases where required

Where privacy laws require a legal basis, we rely on performance of a contract to provide the app and paid features, your consent for optional permissions and optional AI product evaluation, legitimate interests to secure and improve the service, and legal obligations where records must be retained or requests must be handled.

Service providers

We may share limited information with service providers that help us operate Luma Smile: Apple for App Store distribution, in-app purchases, device permissions, and app platform services; RevenueCat for subscription management; OpenAI for optional AI product evaluation; hosting providers for the website and API; and email/support providers for communications. These providers process information according to their own terms, privacy policies, and data processing commitments.

Retention

Local app data remains on your device until you delete entries, uninstall the app, erase device data, or change Apple backup settings. AI product evaluation requests and server logs are retained only as long as reasonably needed to operate, secure, debug, and improve the service, comply with legal obligations, and handle disputes. Support emails are retained for as long as needed to respond and maintain support records. Purchase records are retained by Apple, RevenueCat, and us as needed for subscription access, accounting, fraud prevention, and legal compliance.

Your choices and rights

You can control your information in several ways:

• Delete local entries, photos, or product logs in the app where deletion is available.
• Uninstall the app to remove app data stored on your device, subject to Apple backup behavior.
• Disable camera, photo, and notification permissions in iOS Settings.
• Choose not to submit product photos or notes for AI evaluation.
• Manage or cancel subscriptions through your Apple account.
• Contact us to request access, correction, deletion, export, restriction, objection, or withdrawal of consent where applicable law provides those rights.

We may need to verify your request before acting on it. Some information may be retained where required for security, billing, fraud prevention, legal compliance, or dispute resolution.

Children

Luma Smile is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If local law requires a higher age for consent to digital services, you must meet that age or use the app with appropriate parental or guardian consent.

International processing

Luma Smile and its service providers may process information in countries other than where you live. Those countries may have privacy laws that differ from your local laws. Where required, we use appropriate safeguards for international transfers.

Security

We use reasonable technical and organizational measures designed to protect information processed by Luma Smile. No app, device, network, or online service can be guaranteed to be completely secure. You are responsible for protecting access to your device, Apple account, backups, and email.

Changes to this policy

We may update this Privacy Policy as Luma Smile changes or as legal, technical, or business requirements evolve. The updated version will be posted on this page with a new "Last updated" date. Continued use of the app after an update means the updated policy applies, except where additional notice or consent is required by law.
