Privacy Policy

Version of November 10, 2026.

Who is responsible

Kuaryx is the controller of the data described here. Our contact and data protection officer channel is [email protected].

What Kuaryx never collects

Your wallet's private key and 12 words stay only on your device. They are never sent to Kuaryx.

Data we handle

• App customers: email and a hashed password. If you sign in with Google, we receive your email and an identifier for your Google account.
• Merchants: store name, public wallet address, webhook address and charge data.
• Contact: whatever you send us by email.

What we use it for

• To authenticate your account and provide the billing service.
• To identify payments on the XRP Ledger and notify the merchant.
• To issue merchant invoices and meet legal obligations.

Sign in with Google

Signing in with Google is optional. When you use it, Google tells us your email address, whether it has been verified and an identifier for your account. We store only the email and the identifier.

We use this data only to create your account and confirm it's you when you sign in. We don't access Gmail, Drive, contacts or any other data in your Google account.

We don't sell this data, don't use it for advertising or to train artificial intelligence, and don't transfer it to third parties, except the providers that host the system or when required by law.

Kuaryx's use of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Data on the XRP Ledger

The XRP Ledger is a public network. Transaction addresses, amounts and dates are visible to anyone and cannot be erased, not even by Kuaryx.

Who we share it with

With Google, when you choose to sign in with your Google account, and with the providers that host the system and website, only to operate the service. We don't sell personal data.

How we protect it

Data travels over an encrypted connection (HTTPS). Passwords are stored only as hashes, and access to data is limited to what's needed to run the service. Each merchant can access only its own data.

How long we keep it and how to delete it

We keep the data for as long as your account exists.

To delete your account and the data linked to it, including data received from Google, write to [email protected] from your account's email address. We complete it within 15 days, except for what the law requires us to keep. Your wallet isn't affected: it stays on your device, under your key.

You can also remove Kuaryx's access at any time in your Google Account permissions.

Minors

Kuaryx is not intended for anyone under 18.

Your rights
