We only collect data that's necessary to provide our services and meet regulatory obligations. Sinku stores your registration data such as your email, phone number, and identification details (like NIF/TIN) for two reasons:

• Partner integration: So you can access services like card issuance (via our licensed partner) and other features that require identification
• Ease of access: So you don't need to fill in forms every time you open the app

Important: Certain blockchain transactions are recorded on-chain and are publicly visible. Sinku does not control on-chain data. Your wallet address may be shared with partners to provide services like card issuance.

Your rights

• Access your personal data any time through the app
• Request corrections to inaccurate information
• Request deletion of your data (subject to legal retention requirements)
• Export your data in a portable format
• If you are in the EU, you have additional rights under GDPR including the right to data portability and the right to object to processing

Full details are in our Privacy Policy, available in the app and on our website.
