Terms of Service

Last updated October 13, 2026

1. The service

Tintline ("we", "us") provides temporary access to US mobile phone numbers for receiving SMS messages, including one-time verification codes, through a web dashboard and API. By creating an account you agree to these Terms and to the Acceptable Use Policy, which is part of them.

2. Eligibility

You must be at least 18 years old and able to form a binding contract. One account per person or business. Accounts created to evade a suspension are terminated without refund.

3. Credits, pricing and refunds

• Services are prepaid with account credits. Prices are shown before every purchase and may change for future orders.
• Verifications: charged when started; refunded automatically to your balance if no SMS is received before the window closes, or if you cancel before any SMS arrives.
• Rentals: charged for the full term when started. Unused rentals cancelled within 10 minutes are refunded in full. Otherwise no refund for unused time. Auto-renew charges the same term at expiry while your balance allows.
• Credits are non-transferable and non-refundable to the original payment method except where required by law or at our discretion. Refunds of unused purchased credit may be requested within 14 days of purchase.
• We may credit or refund at our discretion when a number fails to work as described.

4. Numbers

• Numbers remain our property (or our carrier's). You receive a temporary, non-exclusive right to receive messages sent to the number during your session or rental.
• After your session or rental ends, the number may be reassigned to another customer. Messages received after your window are not available to you and are not shown to the next customer when they fall within your window.
• We do not guarantee that any third-party service will accept a given number, that a message will be delivered by the sender or carrier, or that a number has never been used with a particular service.
• Receive-only: outbound SMS and voice calls are not provided unless explicitly offered.

5. Your responsibilities

• Keep your password and API keys confidential; you are responsible for all activity on your account.
• Use numbers only for lawful purposes in accordance with the Acceptable Use Policy and the terms of the services you verify with.
• Do not share, resell or sublicense numbers or access to them without our written agreement.

6. Suspension and termination

We may suspend or terminate accounts that violate these Terms, the AUP, carrier rules or applicable law, or that present fraud or abuse risk, with or without notice. On termination, active numbers are released and remaining credits may be forfeited where the termination is for cause.

7. Disclaimer and limitation of liability

The service is provided "as is" and "as available". To the fullest extent permitted by law we disclaim all warranties, and our total liability for any claim relating to the service is limited to the amount you paid us in the 3 months before the claim. We are not liable for indirect, incidental or consequential damages, including lost accounts, lost profits or lost data.

8. Privacy

Our Privacy Policy explains what we collect and why, including that we store the content of messages received on your numbers so we can show them to you.

9. Changes

We may update these Terms. Material changes are announced on the dashboard; continued use after the effective date is acceptance.
