Privacy Policy

Last updated: October 7, 2026

This Privacy Policy explains what information Barnið ("the app", "we", "us") collects when you use it, why, and who it's shared with. Barnið is a baby-tracking app that helps parents and other caregivers log and share a baby's sleep, feeding, nappy changes, appointments, and the medicines and vitamins they are given.

Who this policy is about

Barnið is used by adults (parents, guardians, and other caregivers) to record care information about a baby. The app is not directed at children, does not knowingly collect information directly from children, and does not offer any account or interface for a child to use directly. The baby's information (name, birth date, photo, and care logs, including medicine records) is entered and controlled by the adult account holder(s) who care for that baby.

Information we collect

• Account identity: when you sign in with Apple or Google, we receive the identifier and (if you allow it) name/email that provider gives us, so we can create your account. We also store the display name you choose, which the other guardians of your baby see next to the entries you log.
• Baby profile: the name, birth date, and (optionally) the photo you add for each baby you track.
• Care logs: sleep sessions, feeding/bottle/pump entries, nappy changes, and appointments you record, including their timestamps and any notes you add.
• Medicines and vitamins: if you use the Medicine and vitamins feature, the medicines and supplements you add for a baby (their name and form, and the dose amount, schedule, course dates, and minimum gap between doses that you enter), and each dose you log as given or skipped, with its time and which guardian logged it. This is health information about your child. You enter it, and it is used to show it back to you and the other guardians of that baby, including in a report you choose to share. The app's developer can also see it in an internal support tool, used only to help you and to keep the app working. It is never used for advertising or analytics. The app does not calculate, recommend, or check doses; it only records what you enter.
• Reminder settings: your medicine reminder choices and quiet hours are stored only on your device. Reminders are local notifications scheduled by your phone and are not sent through our servers.
• Sharing/household data: which guardians have access to a given baby's data, via the invite-code sharing feature.
• Subscription status: whether your household has an active Barnið Premium subscription, managed through Apple's In-App Purchase system.
• Usage analytics: anonymous, non-identifying feature-usage events — for example, that a feed, sleep, or nappy change was logged (and its category, such as "bottle" or "nap"), that a screen was viewed, that a subscription paywall was shown, or that a sync error occurred (and its general type). These events never include your name, your baby's name, free-text notes you've written, medicine names or doses, dates of birth, invite codes, or any other personal content — only fixed, non-identifying category labels and counts. See below for how this is used.

We use a privacy-first, first-party analytics tool (Aptabase) to understand which features people actually use and to catch bugs, so we can make the app better — not to advertise to you. This is for our own internal product decisions only: it is never shared with or sold to advertisers or data brokers, and it is never combined with your account identity or any other company's data about you. Because this analytics use is first-party (our own app talking to our own analytics project) and is never used to link your activity with other companies' apps or websites for advertising or ad-measurement purposes, it falls outside Apple's definition of "tracking," and we do not show an App Tracking Transparency prompt for it.

Who we share information with

• Other guardians you invite: a baby's care data, including its medicine and dose records, is visible to every guardian who has been added to that baby via an invite code — this is a core feature of the app (sharing a baby's care record between parents/caregivers), not a third party.
• Supabase, Inc.: our backend infrastructure provider, which hosts the app's database (including care logs and medicine records), authentication, and file storage (baby photos) on our behalf. Supabase processes data only to provide this hosting service to us and does not use it for its own purposes.
• Apple and Google: used solely as sign-in identity providers, if you choose Sign in with Apple or Sign in with Google. Apple also processes payment/subscription information as the payment processor for In-App Purchases; we never see or store your payment card details.
• Aptabase: our analytics provider, which processes the anonymous, non-identifying usage events described above on our behalf. Aptabase does not receive your name, your baby's name, or any other personal or health-related information, and does not use this data for advertising or share it with third parties.
• People you choose to send a report to: if you use Share report (for example, to send a summary to your baby's doctor or nurse), the report goes through your phone's share sheet to whoever you pick. We don't receive a copy. You can leave medicines out of the report with its "Include medicine and vitamins" switch.

We do not sell your data, and we do not share it with advertisers or data brokers.

Data retention and deletion

Your data is retained for as long as your account exists. You can permanently delete your account and all associated data at any time from Settings → Delete account. Deleting your account removes your authentication record and your baby profiles, including their care logs and medicine records (for any baby where you are the only guardian). If a baby is shared with other guardians, the baby's record continues for them after you leave, and entries you logged for that baby stay with it, shown under a remaining guardian's name. Baby photos and entries you deleted earlier may remain in our storage for a period; email info@eggertmar.com and we will remove them on request. You can also delete a single medicine together with its dose history at any time from Settings → Medicine and vitamins.

Your choices

• The Medicine and vitamins feature is optional: nothing about medicines is stored unless you add one.
• To remove a guardian's access to a baby, email info@eggertmar.com and we will do it for you.
• You can delete your account and data at any time from Settings.
• You can manage or cancel your subscription at any time via your Apple ID subscription settings.

Children's privacy

Barnið is not directed at children and is not intended to be used by children. It is a tool for adults to record care information about a child in their care. We do not knowingly collect personal information directly from children.

Changes to this policy

If we make material changes to this policy, we will update the "last updated" date above and, where appropriate, notify you in the app.
