Privacy Policy

Last updated: 2026-03-27

This Privacy Policy explains how String11, LLC handles personal data in connection with the String11 service.

1) Operator

String11, LLC 8 The Green STE A Dover, DE 19901, United States

Contact: privacy@string11.com

2) Data Categories We Process

Based on current implementation and integrations, data categories include:

  • Contact/authentication data (for example, email used in Magic login flows).
  • Wallet data (wallet addresses used in on-ramp and wallet views).
  • Transaction-related metadata (for example, selected assets/amounts, transaction references returned by providers, transfer metadata).
  • Technical/network data needed for security and operations (for example, IP-derived rate-limit context and request metadata).
  • Support/compliance communications you send to our contact channels.

3) Why We Process Data

We process data to:

  • authenticate users and maintain session security;
  • create and operate on-ramp widget sessions;
  • render wallet balance/activity views;
  • monitor reliability/security and investigate errors;
  • respond to support, legal, privacy, and security requests;
  • comply with legal obligations.

4) Third-Party Processors and Services

The service uses third-party providers that process data in their own systems:

  • Transak: fiat-to-crypto transaction/payment execution and related compliance checks for on-ramp flow.
  • Magic Labs: authentication/login and related account/session functions.
  • Alchemy: blockchain infrastructure/data APIs used for wallet transfer history.
  • Reown AppKit / WalletConnect infrastructure: wallet connection infrastructure for supported wallet flows.
  • CoinGecko: market-price API used to display asset price information.

Public privacy/terms URLs for these providers (for convenience; always review the live site for the current version):

We do not claim control over third-party provider decisions or internal processing logic.

5) Cookies and Tracking

The app may use essential cookies and similar storage for service operation, including authentication/session continuity and wallet connection behavior.

Wagmi/Reown wallet connection storage is configured via cookie-based storage in the current app configuration.

A dedicated cookie notice is publicly available at /legal/cookies.

6) Children

The String11 service is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe we have received such information, contact privacy@string11.com.

7) Legal Bases and Rights Handling

Where applicable law provides privacy rights (for example GDPR/CCPA-style rights), requests can be sent to privacy@string11.com. We handle requests in accordance with applicable law and the technical/legal role boundaries of our service and third-party providers.

8) Data Sharing and Transfer Context

Data is shared with or processed by third-party providers only as needed to operate the service functionality described above. Because providers and infrastructure may operate across jurisdictions, processing/transfers may occur in multiple regions depending on provider architecture. We rely on processors’ published terms and, where applicable, standard contractual or other mechanisms offered by the processor for international transfers.

9) Retention and Security Summary

We retain personal data only as long as needed for the purposes described in this policy, unless a longer period is required by law. Specific retention periods may depend on provider tooling (for example, authentication/session artifacts in Magic, transaction records in Transak, logs on infrastructure). We implement reasonable administrative and technical safeguards, but no online system can be guaranteed completely secure.

10) Automated Decision-Making

We do not use automated decision-making or profiling that produces legal or similarly significant effects solely within the String11 app beyond what third-party providers (for example, compliance checks in the on-ramp widget) perform under their own policies.

11) Changes to This Policy

We may update this Privacy Policy from time to time with notice through our website and/or service interfaces. Continued use after updates are posted constitutes acceptance of the updated policy.
