OCHI stores the bill photos you upload, the line items read from them, the colours and amounts you assign, your display name and your PromptPay mobile number. If a friend submits a bank slip, OCHI also stores that image and the verification result.

To read a bill, the photo is sent to Google Cloud Vision for text positions and Anthropic Claude for grouping lines. Bank slips are also sent to Google Cloud Vision for text recognition. Both services are outside Thailand. Nothing is sold or used for advertising.

The PromptPay QR shown to friends contains your mobile number in plain text. Anyone holding a friend's link can read it. Closing or deleting a bill disables its links.

Bills and photos are kept until you delete them. Deleting your account removes everything. OCHI never receives, holds or moves money; transfers happen in your friends' bank apps and cannot be reversed by OCHI.
