Your shop's data stays on your device. We never receive your sales, receipts or customer records; the only exception is the menu and table orders that pass through QR ordering when the shop turns it on.

Data stored on your device

• Shop details, menu, menu photos, tables, bills, payments, receipts, tax invoices and end-of-day reports are stored only on the device where the app is installed.
• Customer names, addresses and tax IDs that the shop enters for full tax invoices are also stored on the device. The shop is the controller of its own customers' personal data under Thailand's Personal Data Protection Act.
• PromptPay QR codes are generated on the device. The app does not connect to banks or receive money on the shop's behalf.

QR table ordering (when the shop turns it on)

• The app uploads the menu (names, prices, options, photos and the shop name) to order.lnwza.com, which we run on Cloudflare, so the shop's customers can see it.
• Opening a table's QR sends the table name and a bill reference. Items a customer orders there are passed on to the shop's device.
• Customers don't sign up or enter personal details. We don't collect their names, phone numbers or payment details, and no payment happens on that page.
• Orders are held only until the shop's device receives them and are deleted when the bill closes, or within 48 hours at most. The menu and photos stay until the shop changes the menu or turns the feature off.
• Cloudflare processes IP addresses to deliver the page and stop attacks, under Cloudflare's policy.

Camera and photo library

• Used only to take or pick menu photos. Photos are kept inside the app and leave the device only when the shop turns on QR ordering. The app sees only the photos you choose.

Backups

• On iPad/iPhone backups go to your own iCloud Drive; on Android they stay on the device, are included in Google's device backup, or are exported where you choose. We cannot access these files.

Ads (free version)

• The free version shows ads from Google AdMob, which may collect device data such as the advertising identifier (IDFA on iOS, Advertising ID on Android), IP address, device model and ad interactions to serve and measure ads and to prevent fraud.
• The app asks before allowing tracking for personalized ads. If you decline, the app works fully and ads do not use the identifier. Change it on iOS in Settings > Privacy & Security > Tracking, on Android in Settings > Privacy > Ads.
• Google does not receive your shop, menu or sales data from the app. See how Google uses data.
• Once the full version is unlocked, the app no longer loads ads.

In-app purchase

• Payments are handled by Apple or Google Play. We do not receive your card or payment details. The app only stores on the device that the full version is unlocked.

What we don't do

• No accounts, no analytics of our own, and we never sell or share shop data.
• The app is made for businesses and is not directed at children.

Deleting data

• Deleting the app removes all of its data. Backups in iCloud Drive can be deleted in the Files app.
• Turn off QR ordering, or email us, to have the shop's menu and photos removed from order.lnwza.com; cached copies expire within a day.
