Privacy Policy

Short version: the calculator runs entirely in your browser. Your baby's age, wake times and schedules never leave your device — there is no server to send them to.

What we store: your dark/light theme preference in your browser's localStorage. Nothing else. Clearing your browser data removes it.

Analytics: we may use privacy-respecting, aggregate traffic analytics to understand which pages are useful. No advertising identifiers, no cross-site tracking, no sale of personal data.

Third parties: this site currently embeds no third-party advertising. If advertising is introduced in the future, this policy will be updated before that happens.

Children's privacy: we do not knowingly collect any personal information from any visitor, of any age — there is nothing to collect.
