1. Information We Collect

Little Mirrors collects and stores the following information to provide its features:

• Account information — anonymous Firebase Auth ID assigned on first launch. You are not required to provide an email address or name.
• Pregnancy profile — due date, current week, and partner email (if you use Partner Sync).
• Symptom logs — symptoms you record by week and severity.
• Kick Counter and Contraction Timer sessions — timing data stored in Firestore.
• Hospital Bag checklist — your personal checklist state.
• Food & Label checks — queries you send to the AI for safety checks.

This data is stored in Firebase Firestore associated with your anonymous account.

2. AI Features (Lumi)

Little Mirrors includes an AI companion named Lumi, powered by Google Gemini via Firebase AI Logic. The following features send data to Google's servers:

• Daily tips — your current pregnancy week is sent to generate a personalized tip.
• Symptom advice — your symptom description and pregnancy week are sent to Gemini.
• Food & label safety checks — the food or ingredient you enter is sent to Gemini.
• Baby Previewer — if you use this feature, your ultrasound image and optionally photos of both parents are sent to Gemini's image generation model to produce an artistic baby portrait. These images are processed by Google and are not permanently stored by Little Mirrors on its servers. Please only upload images you are comfortable sharing with Google's AI service.

AI conversations and requests are processed by Google under Google's privacy policy. We do not permanently store your AI conversation history on our servers.

3. Authentication

Little Mirrors uses Firebase Authentication. On first launch you are automatically signed in with an anonymous account — no email or personal information is required. Your data is linked to this anonymous account in Firestore. If you uninstall the app without backing up, your anonymous account data cannot be recovered.

4. Partner Sync

You may invite a partner to follow along by entering their email address. This email is stored in Firestore and used only to link partner access to your shared pregnancy data. It is not used for marketing. Your partner can view the same milestones, due date, and baby preview.

5. Photos & Camera

The Baby Previewer feature requests access to your photo library so you can select an ultrasound image or parent photos. Photos are used only for the AI generation request and are not stored permanently by Little Mirrors.

6. Data Security

Your data in Firestore is protected by Firebase security rules that ensure only you (and any partner you have explicitly invited) can access it. All data in transit is encrypted.

7. Data Retention & Deletion

Your data is retained in Firestore for as long as your anonymous account exists. To request deletion of your data, please contact us at wksunshine@gmail.com and we will delete your account and associated data promptly.

8. Third-Party Services

Little Mirrors uses the following third-party services:

• Firebase (Google) — Authentication and Firestore database
• Google Gemini — AI features (tips, advice, image generation)

Please review Google's privacy policy for how these services handle your data.
