FAQ
What do I need to provide for deployment?
A Cloudflare account (free) and an optional domain name. I'll guide you through creating the D1 database and getting your app live in the order.
Can reminders be sent to customers automatically by SMS or email?
In the Basic package you copy the reminder message and send it yourself (WeChat, WhatsApp, SMS, email, or a call) — flexible and free. For truly automatic SMS or email reminders, choose the Premium package or order it as a customization.
I manage multiple branches or client businesses. Can they be kept separate?
Yes. Each workspace is fully independent — signup is invite-code based and data is completely isolated between workspaces.
Is my customer data secure?
Yes. Each merchant's data is strictly scoped and isolated, passwords are hashed with PBKDF2 plus a random salt, and session cookies expire after 14 days. The system never sends anything externally on its own.
Do you support languages other than English?
The UI is currently in English, and both English and Chinese user manuals are included. A multi-language UI can be added as a customization.
