At Fostr, we believe baby logging should be simple, collaborative, and entirely secure. Your family's data belongs to you. This Privacy Policy outlines our transparent intentions for how we store and protect your data.
We will never sell, lease, or share your family's logs, photos, or personal details with data brokers, advertisers, or third parties.
Fostr stores only the information you explicitly choose to log for your child and yourself. This includes:
• Baby Logs: Feeding times (breast, bottle, or solids), diaper counters, nap/sleep schedules, length/weight biometrics, and pediatrician notes.
• Parent Sleep: Logs tracking sleep durations and daily parent wellbeing responses.
• Portrait Vault Photos: Source images you upload to the generative Keepsake Portrait Studio, and the high-resolution generated results.
You own 100% of the information inputted into Fostr. Because Fostr is built with partners and caregivers in mind, data can be shared securely with other caregivers you explicitly invite via unique email invitations. You can revoke caregiver access to child profiles at any time.
When you use the Fostr AI Coach or look at predictive sleep windows, queries are sent securely and anonymously. We do not store your conversational logs or predictions for model-training purposes or commercial advertising.
We support your right to be forgotten. If you decide to leave Fostr, you can request account deletion at any time. Upon request, we will instantly and permanently purge your user authentication records, Firestore databases, and Portrait Vault storage buckets. None of your data will linger on our servers.
Fostr utilizes Google Firebase for industry-standard secure cloud storage, application routing, and authentication. We configure strict Firestore Security Rules to prevent unauthorized users or caregivers from accessing or viewing your baby’s data.
For questions about this policy or to request immediate deletion of your account and child profiles, please contact us at delete@fostr.com or request deletion directly from the Settings menu in the application.
