Data and privacy

What you save

Guest profiles and readings are kept privately on the server for 30 days, linked to your current browser. Signing in transfers those profiles and readings into your account. You can inspect your data and delete your account on the Account page.

Palm images and readings

Images are processed on the server and sent to the configured AI service to identify palm features. The features you confirm are reused in readings. Data is retained while the account remains active; deleting the account removes profiles, images and readings and revokes sign-in sessions.

Cookies and your choices

Mệnh Đạo uses only essential cookies for sign-in, guest profiles, coin throws and card draws. There are no advertising or tracking cookies. Your agreement is remembered for 180 days; Later hides the notice for the current visit. Reopen it using Cookie preferences in the footer.

Payments

SePay reconciles transfers using the order code and amount. After account deletion, the reconciliation ledger retains transaction codes, amounts and status separately from names, email, images and readings. Essential cookies maintain sign-in, card sessions and guest allowances.
