1. Introduction
At Coixa, privacy and security are fundamental to everything we build. This Privacy Policy explains how we handle your information when you use our wallet application.
2. Non-Custodial Philosophy
Coixa is a 100% non-custodial wallet, which means:
- We never store your private keys
- We never have access to your funds
- We never see your recovery phrases
- All sensitive data is encrypted and stored locally on your device
3. Data We Collect
Information stored locally on your device:
- Encrypted private keys and seed phrases
- Wallet preferences and settings
Information we may collect:
- Optional Referral Tracking: If you use a valid referral code provided by an authorized Operator, we collect your device identifier (Device ID) and your wallet address to validate and track the referral. This data is only collected if a referral code is provided.
- Analytics: We collect transaction hashes for successful transactions. This information is used solely to track the aggregate volume of transactions processed by the application and improve our services.
- Fiat On-Ramp Services: If you choose to purchase cryptocurrency using our integrated fiat on-ramp feature, you will be redirected to our third-party on-ramp provider, Onramp.money, to complete the transaction. Identity verification (KYC), payment information, and any personal information required to process your purchase are collected directly by Onramp.money in accordance with their own Privacy Policy. Coixa does not collect, store, or process this information unless required to facilitate the integration (such as receiving transaction status updates).
4. How We Use Your Information
- To provide and maintain the wallet service
- To improve user experience and fix technical issues
- To track aggregate transaction volume and platform usage
- To manage and validate our referral program
- To communicate important security updates
- To process beta applications (if applicable)
- To facilitate communication with third-party fiat on-ramp providers when you choose to purchase digital assets.
5. Data Security
Coixa implements maximum on-device hardware encryption to protect your sensitive data:
- Hardware-backed encryption: We utilize native Keystore (Android) and Keychain (iOS) services for secure key storage
- Biometric authentication: Fingerprint and Face ID integration ensures only you can access your wallet
- On-device processing: All sensitive operations (key generation, transaction signing) happen locally on your device
- Zero-knowledge architecture: We never transmit, receive, or store your private keys or recovery phrases
Your private keys remain encrypted in your device's secure hardware enclave and are never exposed to any network or external service.
6. Third-Party Services
Coixa interacts with blockchain networks and trusted third-party service providers to deliver certain features.
These may include:
- Blockchain RPC providers
- Fiat-to-crypto on-ramp providers (such as Onramp.money)
- Analytics providers
When you use our fiat purchase feature, you will interact directly with the third-party provider. Any personal information, identity verification documents (KYC), or payment information required for that service is collected and processed solely by the provider under its own privacy policy and terms.
Coixa never receives or stores your private keys, recovery phrases, or payment card details.
7. Your Rights
You have the right to:
- Access any personal information we hold about you
- Request deletion of your data
8. Changes to This Policy
We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last updated" date.
