Privacy policy

Tringify for VNPay lets your store take payments through your own VNPay terminal. Tringify builds and runs this app. This policy explains what the app keeps, why, for how long, and who else sees it.

Data we keep

Data Why Kept for
Your VNPay terminal code and its hash secret, encrypted, and the VNPay payment and API URLs you entered To start payments, check them and make refunds at VNPay, and check that payment updates come from VNPay Until your store's data is deleted after you uninstall the app, so earlier payments can still be refunded after you change keys or disconnect
For each payment attempt: the VNPay payment reference and signed payment page link (which includes the IP address the customer's checkout came from), amount, currency, expiry, where the customer returns to, and VNPay's transaction number once paid To answer Tringify's checks, send the customer back to your store and refund the payment Until your store's data is deleted
For each refund: its amount and whether VNPay made it VNPay offers no way to look a refund up, so the app records each one to never send it twice Until your store's data is deleted
The access Tringify gives this app to your store, encrypted To ask Tringify to check a payment as soon as VNPay reports it Until you uninstall the app
The time of the last update VNPay sent To show you that updates are arriving Until you uninstall the app
A record of each install and uninstall message from Tringify To apply each message once 30 days

Data we don't keep

The app keeps no card or bank details, customer names or email addresses. To start a payment it passes the amount, the order number and the IP address the customer's checkout came from (VNPay requires it) to VNPay. Shoppers enter everything else on VNPay's own page. Each payment's result is read from VNPay when Tringify asks.

Who we share data with

  • VNPay, your payment provider, receives the payment and refund details described above, under your agreement with VNPay.
  • Cloudflare hosts the app and its encrypted database.

We don't sell data and don't use it for advertising.

Where data is processed

The app runs on Cloudflare's global network. VNPay processes payments in Vietnam.

Deleting your data

Uninstalling the app removes its access to your store at once. When Tringify asks the app to delete your store's data, 48 hours after you uninstall it, the app erases your keys and everything else it keeps for your store. To ask for a copy of your data or for its deletion at any other time, email support-apps+vnpay@tringify.com.

Your customers' payment records are held by VNPay and by your store in Tringify. Customers who want a copy or deletion of them can contact you, and you can contact VNPay.
