SMS Consent & Opt-In Policy

How users consent: Users provide their mobile number on our dedicated SMS opt-in page (burnerboxx.com/sms-optin) and must manually check a checkbox labeled "I consent to receive SMS messages from Burner Boxx." The checkbox is unchecked by default — no consent is presumed.

At the point of purchasing a subscription or temporary phone number that includes SMS functionality, users are presented with a consent checkbox within the checkout modal. The purchase cannot proceed until the box is actively checked by the user.

• ▸Active consent required: The checkbox is unchecked by default. The user must take an affirmative action (checking the box) to opt in.
• ▸No pre-checked boxes: We never pre-check consent boxes. Consent is never implied from inactivity, existing email usage, or any other service interaction.
• ▸Point of collection: Consent is collected at the exact moment the user provides their phone number or purchases a plan that includes SMS features.

Users who opt in will receive the following types of messages:

• ▸Verification codes & OTPs: One-time passwords and verification codes delivered to the user's temporary phone number for use with third-party services.
• ▸Inbound SMS notifications: Notifications that an SMS has been received on a temporary number.
• ▸Service alerts: Expiration warnings for temporary numbers (e.g., "Your number expires in 1 hour").
• ▸Account recovery: Restore codes and recovery-related messages for subscription restoration (no login required).
• ▸Admin approvals: 4-digit authorization codes for sensitive admin actions (domain rotation, number rotation).

Frequency varies by usage. Users receive messages only when triggered by an action they initiated (e.g., signing up for a service that sends a verification code) or when a temporary number is nearing expiration. We do not send marketing, promotional, or advertising SMS messages.

Typical frequency: 1–10 messages per temporary number session, depending on how many services the user interacts with. Recovery code requests are rate-limited to 1 per minute, max 5 per hour.

Opting in to SMS is not required to use Burner Boxx. The core temporary email service functions fully without any SMS opt-in. Users can:

• ▸Use temporary email addresses without providing a phone number.
• ▸Browse the website, read the blog, and access all public pages without opting in.
• ▸Purchase VPN subscriptions without opting in to SMS.
• ▸Use the Developer API without opting in to SMS (API uses webhook delivery, not SMS).

SMS opt-in is collected only when a user actively chooses to use a feature that requires SMS delivery — such as obtaining a temporary phone number or requesting account recovery via SMS.

Users can opt out at any time. The following opt-out methods are supported:

• ▸Reply STOP: Unsubscribes the user immediately. No further messages will be sent to that number.
• ▸Reply HELP: Returns help information including how to opt out and contact support.
• ▸Reply UNSUBSCRIBE: Also triggers opt-out (same as STOP).
• ▸Automatic expiration: Temporary numbers expire automatically, ending all SMS delivery to that number.

Opt-out is processed immediately. The user will receive one final confirmation message acknowledging the opt-out request, then no further messages will be sent.

We do not share or sell SMS opt-in data. Specifically:

• ▸No third-party sharing: Mobile phone numbers, SMS opt-in data, and text messaging consent are not shared with or sold to third parties or affiliates for marketing or promotional purposes.
• ▸Service providers only: Mobile information is shared only with our SMS service provider (Twilio) for the sole purpose of delivering messages. Twilio does not use your number for marketing.
• ▸Consent is non-transferable: Opt-in consent cannot be transferred, sold, or assigned. It remains a direct 1:1 agreement between the user and Burner Boxx.
• ▸No marketing messages: We never send marketing, promotional, or advertising SMS. All messages are transactional and service-related only.

See our full Privacy Policy (Section 5.5) for additional details on SMS data handling.

Burner Boxx complies with all applicable telecom carrier requirements, including:

• ▸A2P 10DLC: All application-to-person messaging is sent through Twilio's registered A2P 10DLC campaign.
• ▸TCPA compliance: We obtain express written consent (via checkbox) before sending any SMS message.
• ▸CTIA guidelines: Our messaging content and opt-in/opt-out flows follow CTIA Messaging Principles and Best Practices.
• ▸Message & data rates: Users are informed that message and data rates may apply.

When a user opts in, we record:

• ▸The mobile number provided.
• ▸A timestamp of when consent was given.
• ▸The consent text that was displayed (the exact checkbox label).
• ▸The IP address (hashed) for fraud prevention — not linked to user identity.

Consent records are retained for the duration of the user's active service plus 90 days, then automatically purged.
