Terms of Service

Last updated: 2026-03-30

These Terms of Service govern your use of the String11 service.

1) Operator and Service Scope

String11 is operated by String11, LLC, a Delaware limited liability company.

String11 provides a non-custodial web interface that enables users to purchase digital assets through third-party on-ramp providers and receive them directly into user-controlled wallets.

String11 is an interface/facilitator only. String11 is not a broker, exchange, custodian, money transmitter, or payment processor in this flow.

2) Non-Custodial and Third-Party Processing

String11 does not hold, custody, or control your funds, crypto assets, or private keys.

Fiat-to-crypto transaction and payment handling are performed by Transak as a third-party provider. KYC/AML checks in the on-ramp flow are performed by Transak.

Digital assets are delivered directly to user-controlled wallet addresses.

2a) Other third-party services

In addition to Transak (on-ramp payments and KYC/AML in the purchase flow), the interface relies on:

  • Magic Labs for email-based authentication and session functionality for the app.
  • Alchemy for blockchain data APIs used in wallet transfer and activity views.
  • Reown / WalletConnect infrastructure for optional external wallet connection flows.
  • CoinGecko for market-price data displayed in portfolio-related views.

String11 does not control these providers’ systems, policies, or acceptance decisions.

3) User Eligibility and Obligations

You are responsible for complying with all laws that apply to you in your jurisdiction.

You must not use the service if you are located in, ordinarily resident in, or otherwise subject to sanctions or legal restrictions that prohibit use of the service.

You must not use the interface for unlawful purposes or in violation of applicable third-party provider rules, including Transak’s Acceptable Use Policy.

You must provide accurate information to third-party providers and you are responsible for destination wallet accuracy and wallet security.

4) Jurisdiction and Sanctions Restrictions

Service availability is subject to jurisdictional restrictions and third-party provider availability, including Transak-supported jurisdictions.

Restricted jurisdictions include OFAC-sanctioned countries and regions, including but not limited to Iran, North Korea, Syria, Cuba, and Crimea/Donetsk/Luhansk regions.

United Kingdom: The service does not offer promotions, incentives, or referral bonuses at launch. If promotions are introduced later, jurisdiction-specific restrictions (including UK financial promotion requirements) will apply. See the Jurisdiction and sanctions page for additional regional context.

5) No Advice

String11 does not provide financial, investment, tax, or legal advice.

6) Refunds, Chargebacks, and Transaction Handling

Where applicable, transaction disputes, refunds, reversals, and chargebacks are handled under third-party provider terms and policies, including Transak terms and policies. You should review Transak’s Terms of Service and Privacy Policy. The Refunds and transaction handling page summarizes how this interface relates to provider-led payment flows.

7) Limitation of Liability

To the maximum extent permitted by law, String11, LLC is not liable for indirect, incidental, consequential, special, exemplary, or punitive damages, or for loss of profits, revenue, data, goodwill, or digital assets, arising from or related to use of the service, third-party provider actions/decisions, network failures, or user errors (including destination-address errors).

8) Indemnification

You agree to indemnify and hold harmless String11, LLC and its officers, members, contractors, and affiliates from claims, liabilities, losses, damages, and expenses (including reasonable legal fees) arising from your use of the service, your violation of these terms, or your violation of law or third-party rights.

9) Governing Law and Dispute Resolution

These Terms are governed by the laws of the State of Delaware, United States.

Disputes are resolved by binding arbitration administered by the American Arbitration Association (AAA), with venue in Delaware, United States.

To the extent permitted by law, disputes must be brought on an individual basis and not as a class action.

10) Changes to These Terms

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

11) Acceptance by Use

By using the service, you acknowledge that you have read, understood, and accepted these Terms of Service. There is no separate checkout checkbox in the app: continued use of the site and purchase flow (including the embedded provider checkout) constitutes acceptance of the then-current Terms and Privacy Policy as described in Section 10.
