Block9 LLC

Effective Date: April 30, 2026
Last Updated: August 20, 2026

Scope. This California Privacy Notice applies solely to www.block9.app and the consulting, education, workshop, and merchandise offerings of Block9 LLC. Other Block9-affiliated products or applications operated under separate domains — including Agents by Block9 at agents.vb9.app — are governed by their own separate privacy notices.

This notice supplements the Block9 Privacy Policy and is provided in accordance with the California Consumer Privacy Act of 2018, as amended by the California Privacy Rights Act of 2020 (collectively, the "CCPA"), and serves as our "Notice at Collection" under California Civil Code § 1798.100(b). It describes how Block9 LLC collects, uses, discloses, and retains personal information about California residents, and the rights California residents have under the CCPA.

Block9 LLC provides technology consulting, education, and merchandise related to blockchain technologies, customer relationship management, and artificial intelligence. We are technology professionals, not financial, investment, legal, or tax advisors.

1. Categories of Personal Information We Collect

In the preceding 12 months, Block9 may have collected the following CCPA categories of personal information about California residents, depending on how the individual interacted with our Site, Services, merchandise, or educational offerings:

• Identifiers — name, email address, phone number, mailing address, IP address, account identifiers, and (for cryptocurrency payments) wallet addresses and on-chain transaction identifiers tied to a Block9 invoice.
• Customer records — billing and shipping addresses and payment confirmation details. Block9 does not directly store full payment-card numbers, bank-account numbers, or similar sensitive financial account information; those are handled by our payment processors.
• Commercial information — records of services booked, products purchased, returns, and items viewed or added to cart.
• Internet or other electronic network activity — browsing history on www.block9.app, device and browser information, interactions with our Site, and similar usage data collected through cookies and analytics tools.
• Geolocation data — approximate (non-precise) location derived from IP address.
• Professional or employment-related information — job title, company name, and business contact information when an individual engages Block9 on behalf of an employer.
• Audio or visual information — (i) audio of your voice captured when you choose to speak with our AI assistant through our website or by telephone, and transcripts generated from it; (ii) recordings of telephone calls to our published number, which are answered on a recorded line with disclosure at the start of each call; and (iii) session recordings of consulting or workshop sessions, where applicable and with consent, made for quality and reference purposes.
• Inferences — inferences drawn from the above to characterize blockchain, CRM, or AI service interests and preferences.

Sensitive Personal Information. Block9 does not seek to collect categories of "sensitive personal information" as defined by the CCPA — such as Social Security numbers, driver's license numbers, precise geolocation, racial or ethnic origin, religious beliefs, union membership, genetic data, biometric data used for unique identification, health information, or the contents of mail, email, or messages not directed to Block9.

Regarding voice audio: Block9 processes voice audio solely to understand spoken requests and generate responses. Block9 does not use voice recordings or transcripts to create a voiceprint, voice template, or other biometric identifier, and does not use them to uniquely identify or authenticate individuals. We ask that you not share sensitive personal information with the assistant, and we do not request it.

Because we do not use or disclose sensitive personal information for purposes that would trigger the CCPA's "right to limit," that right is not applicable to our processing. If our practices change, we will update this notice and provide the required mechanism.

2. Sources of Personal Information

• Directly from the individual (e.g., when you create an account, contact us, book a session, place an order, attend a workshop, or speak with our AI assistant).
• Automatically through your device when you interact with the Site, via cookies and analytics tools.
• From service providers that perform functions on our behalf (hosting, payment processing, fulfillment, communications, analytics, advertising, artificial intelligence).
• From advertising and analytics platforms used to support marketing.
• From affiliate partners, only to the limited extent they share information about referred purchases.

3. Purposes for Which We Use Personal Information

• Providing, scheduling, and delivering consulting, education, workshop, and configuration services.
• Operating our AI assistant, responding to inquiries received through it, and monitoring its accuracy, quality, and safety.
• Processing payments, fulfilling orders, arranging shipping, and handling returns.
• Communicating with clients about bookings, orders, and service delivery.
• Operating, maintaining, and improving the Site and our Services.
• Marketing and advertising, including measuring effectiveness.
• Detecting, investigating, and preventing fraud, abuse, and security incidents.
• Complying with legal obligations and responding to valid legal process.

4. Categories of Personal Information Disclosed for a Business Purpose

In the preceding 12 months, Block9 may have disclosed the following categories of personal information for a business purpose to the following categories of recipients:

• Service providers — hosting and commerce (e.g., Shopify); payment processors (e.g., Stripe, PayPal, Apple Pay); artificial-intelligence providers (xAI Corp., which processes voice and text conversations with our AI assistant); fulfillment vendors (e.g., Printify); communications and collaboration platforms (e.g., Google Workspace); analytics and advertising platforms; customer-relationship-management systems; and similar operational vendors. Categories disclosed: identifiers, customer records, commercial information, internet activity, geolocation, professional information, audio or visual information, and inferences.
• Affiliate partners — when an individual completes a purchase through an affiliate link (e.g., Amazon, SoloSatoshi LLC, Ryder, Ledger), the partner receives information directly from the individual under the partner's own privacy policy. Block9 does not transmit consumer personal information to affiliate partners outside of the click-through referral itself.
• Legal and safety — government authorities, courts, or other parties where required by law, valid legal process, or where reasonably necessary to protect rights, property, or safety. All categories may be disclosed in this circumstance.

5. Sales and Sharing of Personal Information

Sale. Block9 does not sell personal information for monetary consideration.

Sharing for Cross-Context Behavioral Advertising. Block9 may engage in "sharing" as defined by the CCPA when the Site uses third-party advertising or analytics tools (such as Meta or Google) that may receive identifiers and internet-activity information for cross-context behavioral advertising. Categories that may be shared: identifiers and internet or other electronic network activity. California residents have the right to opt out of this sharing; see Section 8 below.

Block9 does not knowingly sell or share the personal information of consumers under 16 years of age.

6. Retention

Block9 retains each category of personal information only as long as reasonably necessary to fulfill the purposes for which it was collected, including to provide services, comply with legal obligations, resolve disputes, and enforce agreements.

Where personal information is no longer needed for any of the purposes above, Block9 will delete or de-identify it. Data recorded on a public blockchain cannot be deleted — see Section 9.

7. Your Rights Under the CCPA

California residents have the following rights, subject to verification and applicable exceptions:

• Right to Know. Request that Block9 disclose the categories and specific pieces of personal information collected, the categories of sources, the purposes for collection, and the categories of third parties to whom information has been disclosed.
• Right to Delete. Request that Block9 delete personal information collected from you, subject to exceptions permitted by law (including the inability to delete information recorded on a public blockchain, which is immutable and outside Block9's control).
• Right to Correct. Request that Block9 correct inaccurate personal information.
• Right to Opt Out of Sale or Sharing. Direct Block9 not to sell or share your personal information. Block9 does not sell personal information; the opt-out applies to sharing for cross-context behavioral advertising. See Section 8 for how to exercise it.
• Right to Limit Use of Sensitive Personal Information. This right applies only where a business uses or discloses sensitive personal information for purposes beyond those permitted under the CCPA. As described in Section 1, Block9 does not use sensitive personal information for purposes that trigger this right; accordingly, no "Limit" action is required at this time.
• Right to Non-Discrimination. Block9 will not deny services, charge different prices, or provide a different level or quality of service because you exercised any CCPA right.

8. How to Exercise Your Rights

Opting Out of Sharing for Targeted Advertising

You may opt out in any of the following ways:

1. Use our data sharing opt-out page at [DATA-SHARING-OPT-OUT-URL], linked from the footer of every page. This control records your preference directly and is the fastest method for California residents.
2. Use our cookie banner. Select "Decline" or adjust your preferences to withhold consent for advertising and analytics cookies. You can reopen the banner at any time from any page.
3. Enable Global Privacy Control (GPC). If you visit our website with the GPC opt-out preference signal enabled, we will treat it as a request to opt out for the device and browser you used. If we can associate that device with a Shopify account, we will apply the opt-out to the account as well. Learn more at globalprivacycontrol.org.
4. Email us at privacy@block9.app with the subject line "Opt Out." Include the email address associated with your account or orders.
5. Use our contact form at www.block9.app/pages/contact, noting "Privacy request" in the comment field.

Methods 1 through 3 apply to the browser and device you use. A request submitted by email or contact form is applied to your account records.

Verification. To protect your information, we will verify your identity before responding to a Right to Know, Right to Delete, or Right to Correct request. Verification may include matching information you provide with information already in our records (such as confirming your email and recent transaction details). The level of verification will be proportional to the sensitivity of the request.

Authorized Agents. You may designate an authorized agent to submit a request on your behalf. The agent must provide a written authorization signed by you, and Block9 may require you to verify your identity directly and confirm that you authorized the agent.

Response Times. Block9 will confirm receipt of your request within 10 business days and will respond substantively within 45 calendar days. We may extend this period by an additional 45 days when reasonably necessary, with notice to you.

Appeals. If Block9 declines a request, you may appeal by replying to our response email or contacting privacy@block9.app with the subject line "CCPA Appeal." We will respond to appeals within 45 days. You may also contact the California Privacy Protection Agency or the California Attorney General.

9. Public Blockchain Data

When you make a peer-to-peer cryptocurrency payment to Block9, the transaction is recorded on a public blockchain. Public blockchain data — including wallet addresses, transaction amounts, and timestamps — is publicly visible, immutable, and outside Block9's control. Block9 cannot delete, modify, anonymize, or restrict access to information once it is recorded on a public blockchain. Your CCPA rights apply to personal information that Block9 itself collects and controls; they do not extend to data on public blockchains. See our Blockchain & Cryptocurrency Privacy Addendum for detail.

10. Related Policies

This California Privacy Notice should be read alongside the Block9 Privacy Policy, which describes our broader data practices, and the Blockchain & Cryptocurrency Privacy Addendum. Service-related terms (rescheduling, shipping, refunds, payments) are governed by the Refund & Rescheduling Policy and the Shipping Policy, all available at www.block9.app.

11. Changes to This Notice
