Dyne Privacy Policy

Last Updated: December 7, 2025

This Privacy Policy explains how Dyne, Inc. (“Dyne,” “we,” “us,” or “our”) collects, uses, and shares information about you when you use our website, web app, and related services (collectively, the “Service”). It also describes your choices about your information.

By using Dyne, you agree to the collection and use of information in accordance with this Privacy Policy. If you do not agree, you should not use the Service.

1. Information We Collect

We collect information in three main ways: (a) information you provide to us, (b) information we collect automatically, and (c) information from third parties.

(a) Information You Provide

• Account Information: When you create an account or use the Service, we may collect your name, email address, phone number, password, and related profile details.
• Payment & Transaction Information: When you pay a restaurant through Dyne, we collect transaction details such as the restaurant, items ordered, subtotal, taxes, tips, discounts, and total amount. Payment card data is processed by our third-party payment processors; we do not store full card numbers on our servers.
• Reviews & Feedback: If you leave ratings, reviews, comments, or other feedback about a restaurant or your experience, we collect the content you submit.
• Customer Support: If you contact us, we may collect the information you provide in your request (such as your name, email, phone number, and the content of your message).

(b) Information We Collect Automatically

• Usage Data: We collect information about how you access and use the Service, such as pages viewed, features used, time and date of access, and referring/exit pages.
• Device & Log Data: We may collect information about the device and browser you use, including IP address, browser type, operating system, device identifiers, and diagnostic logs.
• Location Data: We may collect approximate location information derived from your IP address and, where you choose to allow it, more precise location from your device (for example, via your browser’s location permissions). We use this information to:
  • Show and recommend nearby restaurants that use Dyne, and
  • Help detect and prevent fraud and suspicious activity.
  You can disable precise location sharing in your device or browser settings, but some features (like location-based recommendations) may not work as intended.
• Cookies & Similar Technologies: We may use cookies, pixels, and similar technologies to remember your preferences, keep you signed in, and understand how you interact with the Service.

(c) Information from Third Parties

• Payment Processors: We receive limited information from payment processors (such as payment status, last 4 digits of a card, and transaction identifiers) to confirm payments and handle disputes.
• Restaurants & POS Systems: We may receive ticket/receipt information and related order data from participating restaurants and their point-of-sale (POS) systems so we can display live receipts and process payments.
• SMS Providers (Twilio): When we send or receive SMS messages through our SMS service provider (such as Twilio), we may receive information about message delivery, timestamps, and other technical metadata.

2. SMS, Phone Numbers & Twilio

Dyne uses SMS as a core part of authentication and transactional communication. We work with third-party SMS providers such as Twilio to deliver these messages.

We may collect and process the following in connection with SMS:

• Your phone number
• One-time passcodes (OTP) and verification codes
• Message content related to authentication and transactions
• Technical metadata, such as timestamps, delivery status, and carrier information

We use SMS and Twilio to:

• Send one-time passcodes (OTP) for account verification and sign-in
• Confirm transactional actions, such as payment confirmations or security alerts
• Help protect your account and reduce fraud

We do not use SMS for marketing or promotional messages.

By providing your phone number, you consent to our use of Twilio or similar providers to send you these messages. Message and data rates may apply. You can opt out of SMS by replying STOP as described in our Terms, but doing so may prevent you from using core features that require phone verification.

3. How We Use Your Information

We use the information we collect for the following purposes:

• Provide and Operate the Service: To create and manage accounts, display live receipts, process payments and tips, and enable diners to pay restaurants through Dyne.
• Authentication & Security: To verify your identity, send SMS one-time passcodes, protect against fraud, and secure the Service.
• Restaurant Recommendations & Discovery: To show and recommend nearby or relevant restaurants, including using your approximate or precise location where permitted.
• Analytics & Insights: To understand how diners and restaurants use Dyne, to provide restaurants with aggregated insights (such as repeat visits or menu item performance), and to improve our features.
• Communication: To respond to your inquiries, send you important notices about your account or transactions, and provide updates about changes to our terms or policies.
• Legal & Compliance: To comply with legal obligations, enforce our Terms and Conditions, and protect our rights, privacy, safety, and property, and that of our users and partners.

4. How We Share Information

We do not sell your personal information. We may share information in the following ways:

(a) Service Providers

We share information with third-party vendors and service providers that help us operate the Service, such as:

• Payment processors
• SMS providers (e.g., Twilio)
• Hosting and infrastructure providers
• Analytics and monitoring tools
• Customer support tools

These providers are authorized to use your information only as necessary to provide services to us and are contractually obligated to protect your information.

(b) Restaurants & Restaurant Partners

When you dine at a participating restaurant and use Dyne, we may share relevant information with that restaurant, such as:

• Details of your visit and order
• Payment and tip amounts
• High-level information about your repeat visits or feedback

We generally provide restaurants with aggregated and/or de-identified insights, but some transaction-specific information is necessarily associated with your visit so they can reconcile payments.

(c) Legal, Safety, and Compliance

We may disclose information if we believe it is reasonably necessary to:

• Comply with any applicable law, regulation, legal process, or governmental request
• Enforce our Terms and other agreements
• Protect the security or integrity of the Service
• Protect the rights, property, or safety of Dyne, our users, restaurants, or the public

(d) Business Transfers

If Dyne is involved in a merger, acquisition, financing, or sale of all or a portion of its assets, your information may be transferred as part of that transaction, in which case we will take reasonable steps to require the recipient to honor this Privacy Policy.

5. Cookies and Tracking Technologies

We may use cookies, web beacons, and similar technologies to provide, personalize, and improve the Service, including to:

• Keep you signed in
• Remember your preferences
• Measure and analyze usage

You can typically set your browser to refuse cookies or to alert you when cookies are being sent. If you disable cookies, some features of Dyne may not function properly.

6. Data Retention

We retain your information for as long as necessary to provide the Service, comply with our legal obligations, resolve disputes, and enforce our agreements.

The specific retention period may vary depending on the type of data, the purpose for which it is used, and our legal obligations (for example, financial and transaction records may be retained for longer periods as required by law or for accounting purposes).

7. Data Security

We use reasonable administrative, technical, and physical safeguards designed to protect your information against unauthorized access, loss, misuse, or alteration. However, no method of transmission over the internet or method of electronic storage is 100% secure, and we cannot guarantee absolute security.

8. Your Choices & Rights

• Account Information: You can update certain account information (such as your email or phone number) by logging into your account.
• Location Data: You can control whether we receive precise location data through your device or browser settings. Disabling location may limit certain features, such as nearby restaurant recommendations.
• SMS: You may opt out of SMS by replying STOP to our messages. However, this may prevent you from using core features that require SMS-based verification.
• Marketing Emails (if any): If we send non-transactional emails in the future, you will be able to unsubscribe by following the instructions in those emails.

California Privacy Rights (CPRA/CCPA)

If you are a California resident, you may have certain rights under the California Consumer Privacy Act (as amended by the CPRA), including the right to:

• Request access to the personal information we collect about you
• Request deletion of certain personal information (subject to exceptions)
• Request correction of inaccurate personal information
• Receive information about how we share personal information
• Be free from discrimination for exercising your privacy rights

9. Children’s Privacy

The Service is intended for adults and is not directed to children under the age of 18. We do not knowingly collect personal information from children under 18. If we learn that we have collected personal information from a child under 18, we will take reasonable steps to delete it.

10. International Users

Dyne currently focuses on use within the United States. If you access the Service from outside the United States, you understand that your information may be transferred to, stored in, and processed in the United States and other countries where our service providers are located.

We may update this Privacy Policy from time to time. When we do, we will revise the “Last Updated” date at the top of this page. If we make material changes, we may provide additional notice (such as by email or prominent notice on our website).
