Privacy Policy

Solune is a cycle-synced nutrition app for women, operated by Solune Labs LLC ("we", "us", "our"). We take your privacy seriously — especially because you trust us with sensitive health data. This policy explains what we collect, why, and how it's protected.

Account information: Email address and password (stored securely via Supabase Auth).

Health & cycle data: Menstrual cycle dates, phase tracking, mood, energy, symptoms, and notes you log in the app.

Nutrition data: Food logs, macro goals, calorie entries, and meal photos you choose to upload.

Device permissions: Camera (for barcode scanning and meal photo analysis), photo library (only when you choose to upload an image), and microphone (for voice meal logging and voice wellness check-ins). We never access your camera, photos, or microphone without your explicit action.

Voice data: When you use voice meal logging or voice wellness check-ins, your audio recording is sent to OpenAI for transcription and analysis. Audio is processed in real-time and is not stored by Solune or OpenAI. We do not retain any voice recordings.

Apple Health data: If you enable Apple Health integration, we read your steps, active calories, workouts, sleep, weight, resting heart rate, heart rate variability (HRV), and body temperature from HealthKit, and write meal nutrition data (calories, protein, carbs, fat) to HealthKit. This data stays on your device and is not sent to our servers.

Analytics data: Anonymous usage data such as feature interactions and session information, used to improve the app. This is not linked to your health or nutrition data.

Your data is used solely to provide the Solune app experience:

• Personalising macro targets to your cycle phase
• Generating AI-powered food insights from meal photos
• Tracking your nutrition and cycle history over time
• Providing phase-based supplement and food recommendations

We do not sell your data. We do not use your health data for advertising.

We take the security of your data seriously. All data stored by Solune is protected by the following measures:

• Encrypted at rest: All data is stored using AES-256 encryption via Supabase.
• Encrypted in transit: All communication between the app and our servers uses TLS/HTTPS — your data is never sent unencrypted.
• Passwords: Passwords are hashed using bcrypt and never stored in plain text. Even we cannot see your password.
• Row-level security: Database rules ensure users can only ever access their own data — not other users'.

As the service provider, we may access aggregated or individual data for the purposes of operating, maintaining, and improving the service, and to provide customer support. We do not access your data for any other purpose.

Supabase: We use Supabase to store your account and app data securely. Data is encrypted at rest and in transit.

OpenAI: When you choose to scan a meal photo, use AI-powered food analysis, or use voice logging, the image or audio recording is sent to OpenAI's API for analysis. By using these features, you consent to your food photos and voice recordings being processed by OpenAI. Images and audio are not stored by OpenAI beyond the API call and are never used to train their models. We do not send cycle or health data to OpenAI. No personal identity information is shared with these services. You can always log meals manually without using AI features.

RevenueCat: We use RevenueCat to manage subscription purchases and verify your premium membership status. RevenueCat processes purchase receipts on your behalf.

Apple Health (HealthKit): If you choose to enable Apple Health integration, Solune can write your meal nutrition data (calories, protein, carbs, fat) to Apple Health and read your steps, active calories, workouts, sleep, weight, resting heart rate, heart rate variability (HRV), and body temperature. This is entirely optional and requires your explicit permission. Health data synced via Apple Health is stored on your device by Apple and is not sent to our servers. We do not sell, share, or use HealthKit data for advertising or marketing purposes, in accordance with Apple's HealthKit guidelines.

PostHog: We use PostHog for anonymous product analytics to understand feature usage and improve the app. No personal health data is shared with PostHog.

We automatically collect basic usage data to keep the app stable and performant, including device type, operating system version, app version, and crash reports. This data is not linked to your health or nutrition data.

We use PostHog, a privacy-focused analytics platform, to understand how users interact with the app — such as which features are used and how often meals are logged. This helps us improve the app experience. Analytics data is tied to your anonymous user ID and does not include your name, email, cycle data, or nutrition details. We do not track you across other apps or websites.

Your data is retained for as long as your account is active.

Deleting your account: You can delete your account and all associated data directly in the app under Profile > Data & Exports > Delete Account. Deletion is immediate and permanent — all meals, cycle logs, daily entries, weight history, and profile data are removed from our servers and cannot be recovered.

You may also request deletion by emailing support@getsolune.com.

You have the right to access, correct, export, or delete your personal data. You can export all your data from the app under Profile > Data & Exports > Export My Data. For any other requests, email us at support@getsolune.com and we will respond within 30 days.

Solune is not intended for users under the age of 12. We do not knowingly collect data from children under 12.

We may update this policy from time to time. We'll notify you of significant changes via the app or email. Continued use of Solune after changes constitutes acceptance of the updated policy.

Solune is a wellness and nutrition tracking app intended for general informational purposes only. The content provided in the app — including cycle phase insights, macro recommendations, supplement suggestions, and food guidance — does not constitute medical advice, diagnosis, or treatment.

Always consult a qualified healthcare professional before making changes to your diet, supplement routine, or health practices, particularly if you have a medical condition, are pregnant, or are taking medication.
