Laidao is built with no user accounts. We never ask for your name, email address, phone number, or any social login. This page explains what data we use, where it is kept, and how to delete it.
| Data | Purpose | Where it is kept |
|---|---|---|
| Birth date, birth time, birth province | Computing your chart, bazi pillars and reading | On your device, and on our server inside the cached reading (never linked to a name or account) |
| Palm photos | Describing your palm lines in words | Photos are never stored. They are analysed in transit and only the text description is kept |
| A random device identifier (UUID) generated by the app | Linking the entitlements you purchase, such as chat quota and Pro+ minutes | On our server. It cannot be traced back to an individual |
| App Store / Google Play transaction identifiers | Validating receipts and preventing duplicate credits | On our server. We never receive your card or payment details |
| Questions you type in the chat room or live session | Answering questions about your own chart | Server memory for the duration of the conversation; cleared when the server restarts |
| The "accurate / not accurate" buttons | Improving reading quality | Counted as per-category totals only, never tied to an individual user |
To deliver the service we share limited data with the processors below. Some are located outside Thailand, which constitutes a cross-border transfer under the Thai Personal Data Protection Act (PDPA):
Under Apple App Store guidelines and the Thai PDPA, we do not send personal data to third-party AI services until you give explicit in-app consent. This consent is separate from the Terms of Use:
You may request access to, correction of, deletion of, or object to the processing of your data.
Deleting purchased entitlements also removes any remaining quota, and this cannot be reversed.
This app is intended for users aged 13 and above. We do not knowingly collect data from younger children.
If we make material changes we will update the effective date above and notify you in the app where appropriate.
