Privacy Policy

Milk Drunk helps parents and caregivers track an infant's feeding, sleep, diapering, and related activity. This policy explains what we collect, how we use and share it, and the choices and rights you have. Milk Drunk is available outside the EU, EEA, UK, and Switzerland. This policy is provided in English; if it is ever translated, the English version governs.

The short version

• We store your baby's profile and the activity you log in the cloud so it's backed up and stays in sync across your devices and with caregivers you invite.
• We treat that activity data as sensitive consumer health data and protect it accordingly.
• We do not sell your personal data, and we do not use it for advertising.
• You can export your data or delete your account (which removes your data) at any time.
• We ask for your consent before storing your data in the cloud.

Information we collect

Account information. When you create an account or sign in (Sign in with Apple, Google, or email), we receive your name and email address and a unique account identifier (Firebase Authentication user ID). If you use the app without an account ("guest"), we assign an anonymous identifier instead.

Health and activity data you provide. Baby profile details (name, date of birth, photo, sex) and the events you log: feeding, sleep, diapering, pumping, medications, growth measurements, and notes. We treat this as consumer health data.

Device information. A device identifier (Apple's Identifier for Vendor) used to deliver push notifications, and basic diagnostics described below.

Diagnostics. Crash and performance data to keep the app reliable, collected via our diagnostics provider (Sentry). We configure this to exclude your personal content.

We do not track you across other companies' apps or websites.

How we use your information

• Provide the core service: store, sync, and display your baby's profile and activity.
• Enable family sync: let caregivers you invite view and (per their role) edit your family's data.
• Send notifications you enable (e.g., feed/nap reminders, caregiver activity).
• Optional data import: when you import data from another app, we may use an AI service (Google Firebase AI Logic / Gemini) to interpret the file's structure. We send only what's needed to map the format (not your data in bulk) as described in-app at import time.
• Maintain security, prevent abuse, and meet legal obligations.

How your information is stored and shared

Cloud storage. Your data is stored using Google Firebase (Cloud Firestore) in the United States, isolated per family by access rules. Cloud sync is always on while you use the app (we no longer offer an on-device-only mode); your consent (below) covers this.

Caregivers. Data you place in a family is visible to the caregivers you invite, according to the role you assign them (e.g., full access, log-only, or view-only).

Service providers (sub-processors). We share data only with providers that process it on our behalf: Google Firebase (authentication, database, cloud functions, push messaging, app attestation, AI import), Sentry (diagnostics), and Apple (Sign in with Apple, subscriptions). Each is bound to protect the data.

We do not sell your personal data, share it for cross-context behavioral advertising, or use your health data for advertising.

Consent and how to withdraw it

Before your data is stored in the cloud, we ask you to consent in the app. You may withdraw consent at any time by deleting your account (Settings → About & Legal → Delete Account). Deleting your account permanently removes your babies, events, and history from our systems. You may export your data first.

Your rights and choices

Depending on where you live (e.g., California, Washington, and other U.S. states), you may have the right to access, correct, delete, or obtain a portable copy of your data, and to confirm we do not sell it. The app provides:

• Access / portability: Settings → Data → Download my data.
• Deletion: Settings → Data → Delete account.
• Export for your pediatrician: Settings → Data → Export (PDF/CSV).

To exercise other rights or ask questions, contact support@milkdrunk.app. We will not discriminate against you for exercising your rights.

Children's data

Milk Drunk records information about an infant, entered by an adult account holder. The service is intended for use by adults (18+ or the age of majority where you live) and is not directed to children, who may not create accounts or use it directly.

Data retention

We retain your data while your account is active and for as long as needed to provide the service. When you delete your account, we delete your associated data, subject to limited retention required by law or for security.

Security

We protect data in transit and at rest using our cloud providers' encryption, restrict access with per-family rules, and verify app authenticity with app attestation (App Check). No system is perfectly secure, but we work to safeguard your information.

Changes to this policy

We may update this policy. If we make material changes, we will update the effective date and, where appropriate, ask you to review and re-consent in the app.
