🧊 Warm — plays instantly. Videos under 3 minutes, and anything recent.❄️ Cold — longer originals rest here, restored in a few hours on request.Long videos always keep a 3-minute highlight warm. Partner Ultra & Ultra keep everything warm, in 4K.
Partner Ultra is free for families managing complex care. Children with Down syndrome, born preterm, with congenital heart conditions, epilepsy, Turner or Prader–Willi syndrome, on growth hormone therapy, autistic children, and others whose days come with more to track. Your child’s profile has fields built for this — fill them in, and Partner Ultra turns on.
Why it’s free, and where your data goes.
It isn’t ads, and it isn’t you.
We don’t sell it. We don’t advertise.
We have never sold or shared personal information with third parties, and we never will. There are no ads in memori, on any plan.
The AI lives on your iPhone.
Predictions, pattern detection and recognising who’s in a photo all run locally, through Apple CoreML. Only two things ever leave the device: the words you type into AI search, and a short summary — your child’s age in months and the like — attached when a paid plan opens an article. Neither includes your free-text notes, your photos, or your child’s name.
So how does this hold up?
Partner Ultra and Ultra, monthly. Partner Ultra costs less in exchange for letting anonymized statistics help medical research; Ultra, for parents who’d rather not, end-to-end encrypts posts, your album and more. From free accounts we take nothing — not ad revenue, not data.
Questions parents ask
Are photos and videos really unlimited?
Yes. Even on the free plan there is no cap on how many you keep, no storage limit, and no expiry. Videos longer than three minutes keep their original in cold storage and come back within a few hours of a request, while a three-minute highlight always plays instantly. Partner Ultra and Ultra keep every original warm, in 4K. To prevent misuse as a general-purpose vault, uploading an extreme amount of photos and videos in a short period may temporarily limit new uploads. Ordinary use won’t come near this, and there is no limit on total storage or on how long we keep it.
What exactly is free?
Feeding, sleep, diaper, temperature and growth logs, photos and videos, family sharing and grandparent invites, Apple Watch and widgets — all free. The paid plans add AI (predictions for the next feeding and sleep, your morning brief, pattern insights, and AI search), voice logging, 4K video, the ability to create private circles, and member-only articles.
What happens to my records if I leave?
Delete your account and every piece of personal data attached to it — logs, photos, videos, growth records — is removed from our servers within 30 days. Deletion can’t be undone. Before you go, you can export your records from settings at any time. There is one exception: statistics contributed through Partner Ultra are anonymized at the moment they are collected and can no longer be traced back to you, so they fall outside deletion requests.
