Privacy policy

Effective September 28, 2026

This account signs you in to Gyeol and Dal. This page explains what the account server stores and how it is used. Records kept by each app follow that app's own policy.

What we store

When you sign in we store your Google account name, email and account ID. Your profile photo is not stored. You can change the name on the account page.

How it is used

Only to keep you signed in and to tell each app that you are the same person. Your account details (name and email) are never used for ads or passed to ad or analytics companies. Ads and analytics inside each app follow that app's privacy policy.

What apps receive

Each app reads only this account's ID, name and email, and keeps its own records on its own server. Records are not shared between apps.

Retention and deletion

Deleting your account removes your account, sessions and service activity. Assessment answers and birth profiles stored only on your device must be removed in each service. Sessions expire after 30 days.

Services we rely on

Google for sign-in, Turso for the database and Vercel for hosting. Their policies apply alongside this one.
