App Harbour ApS ("we") publishes Custody Calendar: Co-Parenting, also shown in the app as CoNest (the "App"). Your privacy matters, especially in a co-parenting context.
We do not collect, see, or sell your data. Your custody calendar, swap requests, expenses, handoff notes, children's information, document list and reminders are stored on your device. If you pair with your co-parent, that shared data is encrypted on your device before it is synced through Apple iCloud, so only the two of you can read it. We operate no server of our own.
None. No analytics, no advertising, no tracking, no third-party SDKs, and no CoNest account.
On your device: everything you enter is stored locally in the App's private storage. A small summary (for example, who has the kids today) is shared with the App's home screen widget on the same device.
Co-parent sync (optional): when you pair using a pairing code, the shared family data is end-to-end encrypted on your device (AES-256-GCM, with a key derived from your pairing code) and stored as an encrypted record in the App's Apple CloudKit database, operated by Apple under Apple's Privacy Policy. The record is named with a value derived from the code, never the code itself. Neither we, Apple, nor other iCloud users can read its contents without your pairing code. Keep the code private and share it only with your co-parent. Syncing requires both of you to be signed into iCloud.
Documents: document files stay on the device that added them. Only the document's title and category are included in the encrypted data shared with your co-parent.
The only external services the App uses are Apple's: iCloud (CloudKit) for co-parent sync and the App Store for purchases. The App does not contact any other server.
Purchases are processed by Apple through the App Store. We never receive or store payment information. The App checks your entitlement with Apple on your device so it can unlock Premium features; the paired co-parent's App learns only that Premium is unlocked for the family.
Notifications: reminders are scheduled as local notifications on your device and are not sent through us. You can turn them off in iOS Settings at any time. The App does not request access to your location, contacts, camera, photos or microphone; documents are added only through the files picker, one at a time, when you choose them.
When you share a document, a pairing code, or (in version 1.1 and later) a PDF summary you create in the App, the content goes only to the app or person you choose in the iOS share sheet. If you email us from the App, your message is sent from your own mail app.
The App is a tool for parents, not directed at children. Parents may enter information about their own children; this stays on their devices and in the encrypted sync record described above. We do not knowingly collect information from children.
Delete any entry at any time. Unpair stops syncing and keeps the data on this device. "Fresh start" in Settings erases all local data on this device and unpairs. Deleting the App removes its local data. Your co-parent's device keeps its own copy of the shared data.
We may update this policy and will post changes on this page with a new date.
