Questions, answered

Will this grow my Google reviews?

By growing happy return visits and offering a one-tap review link — never as a reward, never filtered, never scripted.

How do I get started?

Use the form below. We create your brand and seed the program. You refine it from the dashboard.

How much does it cost?

Terms depend on your venue and market. We’ll walk you through current pricing.

Do I need to build an app?

No. Members use the CHaiNCHaiN app or web wallet. You use a browser dashboard.

Must customers download the app?

The full experience is in the app. They can also join via your QR on chain-chain.cc in seconds.

Can multiple locations share one card?

Yes. Company groups share a stamp card and combined progress, with per-store coupons and staff.

What hardware do I need?

None to start — any phone or tablet. Add a USB/Bluetooth scanner, or a daily self-stamp password.

Is customer data safe?

Grants run server-side, QR tokens expire quickly, sensitive tabs use a staff PIN, and production is locked down with App Check and security rules.
