Your data in Dayday.

Last updated: October 5, 2026.

An account for your household

Dayday uses your name and email for your account, sign-in and messages needed to operate the service. Child profiles, routines and progress are used to display and synchronize your household. Adults you invite into the household can view and edit them.

Google or Apple sign-in

If you choose this option, the provider shares the identity information you authorize, including your email. Dayday links accounts when both email addresses are identical and verified. An Apple private relay address may differ from your usual address and create a separate account.

An optional newsletter

Dayday is free. Receiving the Dayday newsletter is a separate choice, switched off by default. Declining or withdrawing consent does not change your access.

To change your choice, open your account, then “Newsletter Dayday”. Dayday records your choice and its date as proof. This does not include consent to a monExpansion newsletter.

Hosting and connections

Application data is hosted by Cloudflare. Your session and device preferences keep you signed in and remember your display settings. If you connect an AI assistant, it receives household information needed for routines and can edit them. You can revoke its access from your account.
