Quill & Cradle

Privacy Policy

Effective September 2026 · ByteQuill LLC

Quill & Cradle helps caregivers track a baby's feeds, sleep, diapers, medications, milestones, and growth. This policy explains what we collect and how it's handled.

What we collect

We do not collect advertising identifiers, location, contacts, photos, or analytics profiles. We do not use third-party advertising or tracking SDKs, and we never sell or share data with data brokers.

Quill

Quill, the in-app companion, is powered by Anthropic's Claude models through Anthropic's API. When you ask Quill a question, the relevant parts of your household's log and your message are sent to Anthropic to generate the reply and are handled under Anthropic's commercial terms, which do not permit training on your data. Quill can prepare entries for you, but nothing is written to your records until you review and confirm it in the app. Quill's optional check-in notes are produced by fixed rules on our server and involve no AI model at all.

About your child's information

You, the adult account holder, enter and control all information about your child. Children do not use Quill & Cradle themselves and no information is collected from a child. Records about your child are visible only to the caregivers you explicitly invite to your household.

Where data lives

Care records are stored with our hosting provider (Supabase, Postgres, hosted in the region selected at account creation) encrypted in transit and at rest, and cached on your devices so the app works offline. Access is enforced server-side per household membership: only caregivers in your household can read your family's records.

Sharing

We do not sell data and we have no advertising partners or cross-app tracking. Data leaves the service only when you export it yourself, for example a pediatrician report or visit pack you generate and share, or when Quill sends your question and the relevant log excerpts to Anthropic to answer it.

Subscriptions

Quill & Cradle Plus is billed by Apple or Google. We receive a receipt that confirms the subscription is active and its renewal date, never your payment details.

Notifications

Medication reminders, rest window nudges, and visit reminders are scheduled on your device. If push notifications are enabled, our server sends caregiver-activity, reminder, and check-in notifications through Apple's or Google's push service using your anonymous device token. Check-ins are off unless you turn them on, and you can set quiet hours.

Deletion and your rights

Medical disclaimer

Quill & Cradle is a record keeping tool and is not a medical device. Schedule suggestions are generic defaults and are not medical advice. Always verify dosage and timing with your healthcare professional.

Changes

We'll update this document and the effective date if our practices change.
