Privacy Policy

Who this covers

Koa Baby Tracker is offered by ApplixLab. This policy covers the Koa Baby Tracker mobile app and website. If you have a privacy question or request, email support@koababytracker.com.

Information we collect

When you use the app, we process the information needed to provide your account and the features you choose:

• Account and family: name, email address, account and family identifiers, invited members, access permissions and subscription status.
• Baby and care records: your baby’s profile, date of birth, premature birth details if entered, feeding, sleep, diaper, pumping, activity, growth, temperature, medicine, symptoms, immunizations, allergies, visits, notes, milestones and photos.
• Content you send: messages and relevant care records used in Koa chat, and support or feedback messages with optional screenshots.
• Device and service information: push notification token, AI usage counts, and app version, platform and sync details included with support requests.
• Purchases: subscription and entitlement information from Apple, Google and our purchase provider. We do not receive your payment card number.

The website is a static site. It does not set analytics or advertising cookies. If you email us, we receive the information you choose to send.

How we use it

We use information to sign you in; save, sync and show your logs; share records with family members you invite according to permissions; create charts and reports; answer Koa chat questions; deliver reminders and notifications; verify Premium access; respond to support requests; and protect and maintain the service.

Koa chat sends the message you write and relevant record context to an AI service so it can respond. Do not enter information you do not want processed for that purpose. Koa’s answers are general information, not medical advice.

Who receives information

We do not sell personal data or use it for advertising or cross-app tracking. Your baby’s records are visible to you and the people you invite, within the access you grant them.

We use service providers to run the app: Supabase for sign-in, database and file storage; Anthropic for Koa chat; RevenueCat for subscription status; and Expo, Apple or Google for notification delivery and store services. When you use voice input, the device’s speech recognition service may process audio; it may use Apple or Google servers if on-device recognition is unavailable. Their access is limited to the services they provide, and we require privacy protection consistent with this policy and applicable law.

We may disclose information if required by law or to protect the safety, rights or security of users and the service.

Storage and retention

Your account and care records are stored while your account is active unless you delete individual records or your account. The app keeps recent data on your device for offline use and syncs it with hosted storage. Individually deleted care records are normally purged from the service after 90 days. A baby profile deleted on its own can be held for up to 12 months to allow recovery. Chat history, AI activity logs and audit records are normally removed after 12 months; daily AI usage counts after 3 months. These recovery periods do not apply when the account owner deletes their entire account.

Backup copies may remain for a limited period under our hosting provider’s retention process. Service providers may process data in countries other than yours.

Family members you invited can see permitted records while they have access. Removing a member revokes future access, but cannot erase copies they previously exported or saved outside Koa.

Your choices and deletion

In the app, go to Settings → Your data to export your data or choose Delete my account. Account deletion removes your profile and the baby records in families you own, along with the account’s support messages and uploaded support screenshots. It cannot be undone. If you belong to another person’s family, deleting your account removes your access but does not delete records owned by that family.

You can edit records in the app, change family permissions, remove members and turn off notifications in device or app settings. To request access, correction or deletion under applicable law, email us at support@koababytracker.com.

Children’s information

The app is for adults caring for children. Children do not create accounts. A parent or caregiver may enter a child’s information to use the tracking features. Please share it only with people you trust and use family permissions to limit access.

Security and changes

We use account authentication, access rules and private storage to limit who can access records. No online service can promise absolute security. We may update this policy as the app changes; the updated date will appear at the top of this page. Material changes may also be communicated in the app where appropriate.
