Export and diary backup

How to download the whole history as CSV files, and how to keep a copy of a diary that lives only on this device.

Updated October 4, 2026

CSV export — always free

The export is a ZIP of CSV files, one per kind of entry, that open in any spreadsheet. It is free in every plan and after Premium ends.

  1. Open More → Settings, then Settings in the App group, section Data → CSV export.
  2. Choose the children and the period — the whole history or chosen days.
  3. Tap Prepare the file. It usually takes a few seconds; you can close the screen, because we also e-mail you the link. The link is valid for 24 hours.

The file is built from what is on the server, so it needs an account and a connection, and entries still waiting on your phone are not in it yet. Photos and voice notes are not in the file — only their list.

The file holds your child's health data and is not encrypted — keep it like medical records.

Diary backup — a JSON file from this device

Diary backup in the same Data section saves a JSON file with the whole diary from this phone. It is the way to keep a copy before you create an account, because until then the diary lives only on this device. A backup can be restored only into an empty diary on a device without an account.

Copies sent by e-mail
