Communications

We may maintain records of communications you have with us through:

• Email

• Customer service requests

• Telephone calls

• Social media

Website and Device Information

When you use our website, certain information may be collected automatically, including:

• IP address

• Browser type

• Device type

• Operating system

• Pages viewed

• Referring websites

• Approximate geographic location derived from an IP address

• Dates and times of website activity

• Cookie and similar technology identifiers

We may use cookies, pixels, analytics technologies, and similar tools to operate the website, understand website performance, improve customer experience, prevent fraud, and measure marketing effectiveness.

2. How We Use Personal Information

We may use personal information to:

• Process and fulfill orders

• Provide custom tuning services

• Evaluate vehicle configurations and modification requests

• Recommend products, parts, tuning options, or services

• Communicate regarding orders, tune requests, technical questions, and customer support

• Provide requested revisions or continuing tuning support

• Send service-related email or text communications when authorized

• Send marketing communications when separately authorized

• Process payments, refunds, returns, and shipping

• Maintain customer and order records

• Analyze website traffic and business performance

We may also use information for another purpose disclosed to you at the time the information is collected.

3. SMS and Text Messaging Privacy

Piston Twistin LLC may offer optional text messaging for customers who expressly choose to receive SMS communications.

Depending on the consent you provide, text messages may include communications concerning:

• Custom tune requests

• Vehicle information or requirements

• Parts orders

• Order status

• Product or technical support

• Customer service

• Special offers, discounts, product updates, or promotional messages when separately authorized

SMS consent is voluntary. Providing a mobile number does not by itself constitute consent to receive marketing text messages.

Where SMS consent is requested through a website form, consent options are presented separately and are not preselected.

Message frequency varies. Message and data rates may apply.

You may reply STOP to a text message to opt out of future messages from that messaging program. You may reply HELP for assistance.

Mobile Information and Consent Are Not Shared for Marketing

Piston Twistin LLC does not sell, rent, share, or provide your mobile phone number, SMS opt-in information, or text messaging consent to third parties or affiliates for their own marketing or promotional purposes.

Text messaging originator opt-in data and consent are excluded from any disclosure of information to third parties or affiliates for marketing or promotional purposes. SMS consent is specific to Piston Twistin LLC and is not transferred to another business for that business to market to you.

We may use service providers that process information solely on our behalf as necessary to operate communications infrastructure, deliver messages, maintain customer records, or provide telecommunications services. Such providers are not authorized to use SMS opt-in information for their own marketing purposes.

Your decision not to consent to promotional SMS messaging does not prevent you from purchasing products or services from Piston Twistin LLC.

This section is intentionally explicit because Twilio currently treats mobile-number and SMS-consent sharing as a separate A2P vetting issue.

4. Email Communications

We may use your email address to respond to inquiries, provide tune information, communicate regarding orders, deliver requested information, and provide customer support.

If you subscribe to marketing emails, we may also send information about products, promotions, discounts, updates, or other Piston Twistin offerings.

You may unsubscribe from promotional emails by using the unsubscribe mechanism provided in the communication. Transactional, order-related, or customer-service communications may still be sent when necessary.

5. How We Disclose Information

We may disclose personal information to service providers and business partners that perform services on our behalf, including providers involved with:

• Website hosting and ecommerce

• Customer relationship management

• Online forms and surveys

• Payment processing

• Order fulfillment

• Shipping and delivery

• Email communications

• Telecommunications

• Data hosting

• Fraud prevention

• Analytics

• Advertising and marketing technology

• Accounting, legal, or professional services

For example, our website and ecommerce functionality are operated using Shopify, and certain customer intake, communication, and customer-management functions may be provided through CRM or communications platforms.

These providers may access personal information only as reasonably necessary to perform services for us, subject to their agreements and applicable law.

The disclosures described above do not authorize any third party or affiliate to use your mobile number or SMS opt-in consent for its own marketing or promotional purposes.

We may also disclose information:

• When required by law, subpoena, court order, or legal process

• To governmental or regulatory authorities when legally required

• To investigate suspected fraud, misuse, or unlawful activity

• To protect our legal rights, customers, systems, property, or safety

• In connection with a merger, acquisition, financing, reorganization, sale of assets, or similar business transaction, subject to applicable law

We do not sell SMS consent or mobile opt-in information.

6. Advertising, Analytics, and Cookies

We may use cookies and similar technologies to operate our website, remember preferences, understand how visitors use the website, measure advertising performance, and improve our services.

Certain analytics or advertising providers may receive device identifiers, cookie information, IP addresses, browsing activity, or similar online information.

Depending on applicable privacy law, some advertising-related disclosures of online information may be considered “sharing,” “targeted advertising,” or similar activity.

This does not include the sale or disclosure of SMS opt-in consent or mobile phone numbers to third parties or affiliates for their own marketing or promotional purposes.

You may be able to control certain cookies through your browser settings and through privacy choices made available on our website.

7. Shopify and Other Service Providers

Our online store is hosted through Shopify. Shopify processes certain information necessary to provide ecommerce, checkout, security, fraud prevention, and related services.

We may also use third-party providers to support customer relationship management, surveys, communications, hosting, analytics, payments, fulfillment, and other operational functions.

These providers maintain their own privacy practices regarding information they process in connection with their services.

Shopify provides merchants with customer-privacy controls and tools, but Shopify also makes clear that merchants remain responsible for the accuracy of their own published policies.

8. Data Retention

We retain personal information for as long as reasonably necessary to:

• Provide requested products or services

• Maintain tuning and support history

• Fulfill orders

• Maintain business and accounting records

• Resolve disputes

• Enforce agreements

• Prevent fraud or abuse

• Meet legal, tax, regulatory, or contractual obligations

Retention periods may vary depending on the type of information and the reason it was collected.

When information is no longer reasonably necessary, we may delete, anonymize, or securely dispose of it, subject to applicable law and technical limitations.

9. Data Security

We use reasonable administrative, technical, and organizational safeguards designed to protect personal information against unauthorized access, loss, misuse, alteration, or disclosure.

However, no website, network, database, transmission method, or storage system can be guaranteed to be completely secure. You should use reasonable care when transmitting information electronically.

10. Your Privacy Rights

Depending on where you reside and the laws applicable to you, you may have rights concerning your personal information, including the right to request:

• Access to personal information we maintain about you

• Correction of inaccurate personal information

• Deletion of certain personal information

• A copy of certain personal information

• Information about categories of data collected or disclosed

• Opt-out of certain targeted advertising, sale, or sharing activities where applicable

• Withdrawal of consent where processing is based on consent

Privacy rights vary by jurisdiction and may be subject to exceptions.

support@pistontwistin.org

We may need to verify your identity before completing certain requests. We will not discriminate against you for exercising privacy rights provided by applicable law.

11. Marketing Choices

You may control marketing communications as follows:

Email: Use the unsubscribe link included in promotional email communications.

SMS: Reply STOP to opt out of an SMS messaging program.

Opting out of marketing communications does not prevent us from contacting you regarding an existing transaction, order, service request, support matter, legal notice, or other non-promotional communication where permitted by law.

12. Children’s Privacy

Our website, automotive products, and tuning services are not directed toward children under 13 years of age.

We do not knowingly collect personal information from children under 13 through the website. If we learn that such information has been collected without appropriate authorization, we will take reasonable steps to delete it.

13. International Visitors

Piston Twistin LLC operates from the United States.

If you access our website from outside the United States, information may be transferred to, stored in, or processed in the United States or other locations where our service providers operate.

Privacy laws in those jurisdictions may differ from the laws in your location.

14. Third-Party Websites

Our website may contain links to third-party websites, social media platforms, product manufacturers, payment providers, or other services that Piston Twistin does not operate.

We are not responsible for the privacy practices of third-party websites or services. We encourage you to review their privacy policies before providing information to them.

15. Changes to This Privacy Policy

We may update this Privacy Policy periodically to reflect changes in our business, services, technology, legal obligations, or privacy practices.

When changes are made, we will update the “Last Updated” date at the top of this policy.

Material changes may also be communicated through the website or other appropriate means when required.
