Bably is a baby tracker app built by a small independent team. This policy explains what data we collect, why, and what control you have over it. Short version: we collect what we need to make the app work, we do not sell or share it for advertising, and you can delete everything at any time.
Who we are
Bably is the controller of personal data described in this policy. You can reach us at bably@k8n.pro.
What we collect
- Account: email address if you sign in with email, Google or Apple. Anonymous use is supported — in that case we generate an internal user ID with no personal data.
- Child profile: name, birth date, gender and tracking preferences you enter.
- Activity logs: feedings, sleeps, diapers, growth, temperature, mood, appointments — only what you enter.
- Device data: timezone, locale, push notification token if you enable notifications.
- Subscription data: Apple sends us the transaction ID, product ID, expiration and renewal status. We never see your payment method or Apple ID.
What we do NOT collect
- No advertising identifiers.
- No third-party trackers (no Facebook Pixel, no Google Analytics).
- No location data.
- We do not sell your data, ever.
Legal basis (GDPR)
We process your data on the basis of the contract we have with you to provide the Service (Art. 6(1)(b) GDPR) and on the basis of your consent for optional features such as notifications (Art. 6(1)(a) GDPR). You can withdraw consent at any time without affecting the lawfulness of prior processing.
How we use the data
- To provide tracking, statistics, reminders and sharing features.
- To deliver push notifications you have enabled.
- To verify your App Store subscription.
Family sharing inside the app
If you invite a caregiver, they receive access to the child profiles and activity logs you share with them. You can remove access at any time in Settings → Family.
Retention
We keep your data while your account exists. Delete your account in Settings → Account and we remove your profile, child profiles, activity logs and any caregiver shares immediately and irreversibly.
Subprocessors
- Apple — App Store, APNs push, StoreKit subscriptions.
- Google — Sign in with Google (only if you use this method).
- Contabo — hosting (data centre in Germany — EU/EEA).
- Cloudflare — off-site database backups (R2).
Your rights
You have the right to access, rectify or delete your data, to restrict or object to processing, and to data portability. To exercise any of these rights, email bably@k8n.pro. You also have the right to lodge a complaint with your local data protection authority.
Children
Bably is intended for parents and caregivers tracking their own infants and young children. We do not knowingly collect personal data from children under 13.
Changes
We may update this policy. Material changes will be communicated through the app at least 30 days before they take effect.
