Privacy Policy

Last updated: March 16, 2026

1. Introduction

Thank you for trusting lunawind with your personal thoughts and information. When you use lunawind, you share your feelings, moods, and experiences—and we take that responsibility seriously.

lunawind ("we," "us," or "our") is committed to protecting your personal information and your right to privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use the lunawind mobile application and related services (the "App").

Please read this privacy policy carefully. If you do not agree with the terms of this privacy policy, please do not access the App.

2. Our Promise

Your privacy is at the heart of why we built lunawind. We make a simple promise:

  • Your data is yours. We do not sell your personal information.
  • We do not use your data to train AI models. Your conversations and mood data are not used for model training purposes.

We believe transparency builds trust, so this policy explains what we collect, why we collect it, and how we protect it.

3. Information We Collect

We collect several types of information from and about users of our App:

  • Account information: When you sign in with Google or Apple, we receive your name, email address, and profile picture from the authentication provider. We use this to create and manage your account.
  • Conversation data: The messages you send in chat, which we process to provide AI-powered support responses.
  • Mood and wellness data: Your mood check-ins, breathing exercise usage, and other wellness-related inputs you provide.
  • Voice input: When you use voice input, your speech is sent to Google (on Android) or Apple (on iOS) for speech-to-text transcription. We receive only the transcribed text, not the audio.
  • Device and connection information: In accordance with your device settings, we may receive information such as your device model, operating system, IP address, and identifiers needed to operate the App.

4. How We Use Your Information

We use your personal data for the following purposes:

  • To provide, maintain, and improve the App and its features
  • To create and administer your account
  • To process your chat messages and deliver AI-powered responses
  • To store and display your mood check-ins and wellness data
  • To facilitate subscription payments for premium features
  • To prevent and investigate fraud, abuse, and violations of our Terms of Service
  • To comply with legal obligations and enforce our policies

5. Disclosure and Third-Party Services

We may share information in the following situations:

  • Business transfers: In connection with a merger, sale of assets, financing, or acquisition of our business
  • With your consent: For any other purpose with your explicit consent
  • Legal obligations: When required by law or in response to valid requests by public authorities

5.1 Third-Party Service Providers

We use trusted third-party service providers to operate lunawind. These providers process data on our behalf only as needed to provide their services.

  • Google Sign-In / Apple Sign-In: We use Google and Apple authentication to manage sign-up and login. These providers process your email, name, and profile information to keep your account secure.
  • Google (Gemini): To power AI conversations, we send your chat messages to Google's Gemini API. Your message text is processed to generate responses. Google's use of API data is governed by their privacy policy. We do not use your data to train AI models.
  • Google / Apple Speech Recognition: When you use voice input, your audio is sent to the device's default speech recognition service (Google on Android, Apple on iOS) for transcription. We receive only the resulting text. Please refer to Google and Apple privacy policies for how they handle voice data.
  • RevenueCat: We use RevenueCat to manage subscriptions and process payments through the App Store and Google Play. RevenueCat may receive your account identifier and purchase information. Payment details are handled by Apple or Google.

We do not use analytics tools or advertising providers. Your conversations and personal reflections are never sent to advertising or marketing services.

These third-party providers have their own privacy policies. We encourage you to review them.

6. Data Retention

We retain your personal information only for as long as necessary to provide the App, comply with legal obligations, resolve disputes, and enforce our policies. When you delete your account, we will delete or anonymize your personal data in accordance with our data retention practices, except where we are required to retain it by law.

7. Data Security

We implement appropriate technical and organizational measures to protect your personal information:

  • Encryption in transit: All data transmitted between the App and our servers is encrypted using industry-standard TLS/HTTPS
  • Access controls and authentication mechanisms to limit who can access your data

Please note that no method of transmission over the Internet or electronic storage is 100% secure. While we strive to protect your personal information, we cannot guarantee absolute security.

8. Your Privacy Rights

Depending on where you live, you may have certain rights regarding your personal data:

If you are in California (CCPA): You may have the right to know what personal data we collect and how we use it, the right to request deletion of your data, the right to opt out of the sale of your personal data (we do not sell your data), and the right to not be discriminated against for exercising these rights.

If you are in the EU, UK, or Switzerland (GDPR): You may have the right to access, correct, or delete your data; the right to restrict or object to how it is used; the right to data portability; and the right to withdraw your consent at any time.

To exercise these rights, please contact us at support@lunawind.app. We will respond to your request within 30 days.

9. International Data Transfers

Your information may be transferred to and processed in countries other than your country of residence, where data protection laws may differ. By using the App, you consent to such transfer. We take appropriate safeguards to protect your information in accordance with this Privacy Policy.

10. Children's Privacy

Our App does not permit anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13. If we discover that a child under 13 has provided us with personal information, we will delete it from our servers. If you become aware that a child under 13 has provided personal data to us, please contact us at support@lunawind.app.
