A baby tracker with no ads and optional analytics

The short answer

Our Baby Day carries no advertising, and your baby’s records are not sold or shared for marketing. Optional usage analytics go to Mixpanel and crash diagnostics to Sentry only after your permission. They exclude baby records, photos and Ask conversations. You can log without an account; family sharing and Ask are separate choices described in our privacy policy.

What does leave, when you opt into it, is listed rather than summarized: syncing with another caregiver, Ask, an import file the phone cannot read, and the emails that carry a sign-in code. Deleting your account removes your profile and sign-in from the servers, and any family only you belong to with everything in it; in a family shared with other caregivers, the entries and photos you added stay with the family.

No ad network to opt out of, and analytics only if you say yes.

The app's Privacy and data screen, listing what leaves the phone
The same list is in the app, on Settings › Privacy & data — and its wording is pinned to a security audit by a test.

The whole list of what leaves the phone

  • Nothing, if you skip sign-in and leave analytics off. Logging, timers, widgets, charts and the nap forecast all run locally.
  • Sharing with a caregiver. The entries have to reach the other phone, so they go through our database.
  • Ask. The question and the records needed to answer it go through our server to a third-party AI provider with zero data retention: nothing is kept once the answer comes back, nothing is used for training, and the conversation itself stays on your phone.
  • An unreadable import file. Sent to the same provider to be parsed, and only when your phone could not read it itself — the app asks you first, before it goes.
  • Sign-in emails. Your address, to send the code.

Getting it all back, or getting rid of it

Export whenever you like: a spreadsheet, or a zipped backup with every stored field and photo. Settings › Data › Delete all data clears this phone when you are signed out, and your family’s logs for every caregiver when you are signed in. Settings › Account › Delete account removes your profile and sign-in from the servers, and any family only you belong to with its babies, records and photos; in a family shared with other caregivers, the entries and photos you added stay with the family. Neither cancels a subscription — that lives with your Apple ID.

Why the wording is so specific

Because a claim that is not checked drifts. The privacy copy inside the app is tied to a security audit of the code by a test that fails if the two disagree, so a new outbound call cannot ship without the sentence that describes it. The full policy is on the privacy page.

Questions people ask

Do I have to make an account?
No. The sign-in screen has a skip button, and everything on your own phone works without one. An account is needed only for sharing and for Ask.
Is my baby's data used to train an AI model?
No. Ask sends the question and the relevant records to a model provider under a setting that forbids retaining or training on them, and that is the extent of it.
Are there ads?
None, anywhere, and there is no free tier carrying them either — the app is a subscription, and that is the whole of how it is paid for. Nothing in it is sold, and your baby's records are not shared for marketing.
