Privacy Policy

Effective date: August 14, 2026 • Last updated: August 14, 2026

This Privacy Policy explains how Sirica Therapeutics Inc., doing business as Sirica Center (“Sirica,” “we,” “us,” or “our”), collects, uses, discloses, and protects personal information through Siricatx.com and related online forms and communications that link to this Policy (collectively, the “Services”).

1. Scope and relationship to health privacy notices

This Policy covers personal information collected through the Services. If Sirica is a healthcare provider subject to the Health Insurance Portability and Accountability Act (“HIPAA”), protected health information (“PHI”) that Sirica maintains as a covered entity is also governed by its separate Notice of Privacy Practices (“NPP”). If this Policy conflicts with the NPP regarding PHI, the NPP controls. Website technologies and data held by third parties may not always be PHI under HIPAA, but may be protected by other privacy laws.

2. Personal information we collect

The categories and specific information collected depend on how you interact with us.

  • Contact and lead information: name, email address, telephone number, postal address, preferred contact method, referral source, and communications with us.

  • Health and therapy information: age or date of birth, diagnoses or conditions you choose to disclose, therapy history, support needs, mobility, sensory or seizure considerations, goals, availability, intake responses, appointment details, and other information relevant to evaluating or providing services.

  • Payment and transaction information: billing contact, payment status, purchases, invoices, and limited payment-card details. Our payment processor may collect full card information directly under its own privacy policy.

  • Device, usage, and analytics information: IP address, browser and device type, operating system, pages viewed, links clicked, referring URL, approximate location derived from IP, timestamps, cookie or similar identifiers, and interactions with forms or emails.

  • Communications preferences: newsletter subscription, SMS appointment-reminder consent and opt-out status, and related records.

  • Information from third parties: information from a parent, guardian, caregiver, referring provider or organization, scheduling/form provider, payment processor, analytics provider, or other service provider, where permitted by law.

3. How we collect information

  • Directly from you or your authorized parent, guardian, or caregiver through forms, appointment requests, email, telephone, SMS, payments, events, and in-person interactions.

  • Automatically through cookies, pixels, logs, and similar technologies when you use the Site.

  • From service providers and other third parties at your direction or as permitted by law.

4. How we use personal information

  • respond to inquiries and provide requested information;

  • evaluate requests, schedule and manage appointments, and provide appointment reminders;

  • conduct intake and provide or administer therapy-center services;

  • process payments, maintain transaction records, and prevent fraud;

  • operate, secure, debug, personalize, and improve the Services;

  • measure website performance and understand engagement;

  • send newsletters or marketing communications when permitted, and honor preferences;

  • comply with legal, regulatory, licensing, safety, and recordkeeping obligations; and

  • protect the rights, safety, and property of clients, users, Sirica, and others.

We will not use personal information for materially different, unrelated, or incompatible purposes without providing notice and obtaining consent when required.

5. Cookies and similar technologies

We and our service providers may use essential, functionality, analytics, and—only if enabled—advertising cookies or similar technologies. Essential technologies support security and Site operation. Analytics technologies help us understand Site use. You can control cookies through browser settings and, where offered, our cookie-preference tool. Blocking cookies may affect Site functions.

If we use technologies that constitute a “sale” or “sharing” of personal information under California law, and that law applies to us, we will provide the required “Do Not Sell or Share My Personal Information” mechanism and process recognized opt-out preference signals as required.

6. How we disclose personal information

We may disclose personal information to:

  • service providers and contractors supporting website hosting, forms, CRM, scheduling, communications, analytics, security, payment processing, professional services, and IT operations, subject to appropriate contractual restrictions;

  • healthcare professionals, caregivers, or other persons at your direction or as authorized or required by law;

  • government authorities, regulators, law enforcement, courts, or other parties when required by law or reasonably necessary to protect rights, safety, and security;

  • parties to a merger, financing, acquisition, reorganization, bankruptcy, or sale of assets, subject to appropriate protections; and

  • other parties with your consent or at your direction.

Sirica does not sell personal information for money. We do not use or disclose sensitive personal information to infer characteristics about individuals except as permitted by law.

7. Health information and tracking technologies

Please avoid including unnecessary health details in general website, newsletter, or contact forms. Where Sirica is subject to HIPAA, it will use HIPAA-appropriate systems and agreements for PHI where required. Sirica should not configure website analytics or advertising tools to receive PHI from authenticated patient pages, appointment workflows, or health-related form fields unless counsel and privacy/security personnel approve the configuration and all required safeguards and agreements are in place.

8. Data retention

We retain personal information for as long as reasonably necessary for the purposes described in this Policy, including to provide services, comply with clinical and legal record-retention requirements, resolve disputes, enforce agreements, and maintain security. Retention periods vary by record type, relationship, and legal obligation. We may retain deidentified or aggregated information where permitted by law.

9. Security

We use reasonable administrative, technical, and physical safeguards designed to protect personal information. No method of transmission or storage is completely secure, and we cannot guarantee absolute security. Email and SMS may be unencrypted; do not send sensitive health or payment information through those channels unless specifically instructed through an approved secure process.

10. Your choices

  • Email: use the unsubscribe link in marketing emails. We may still send non-marketing service communications.

  • SMS: reply STOP to end appointment-reminder texts; reply HELP for help. Opting out of SMS does not cancel an appointment or prevent essential communications by other agreed methods.

  • Cookies: use browser settings and any available cookie-preference tool.

  • Access or correction: contact us using the details below. Rights vary by applicable law and the type of record.

11. California privacy rights

If Sirica is subject to the California Consumer Privacy Act, as amended by the California Privacy Rights Act (“CCPA”), California residents may have rights to know/access, correct, delete, and obtain portable copies of personal information; to opt out of sale or sharing; to limit certain uses and disclosures of sensitive personal information; and not to receive discriminatory treatment for exercising CCPA rights, subject to exceptions. Certain medical information, PHI, and other data may be exempt from some CCPA provisions.

To submit a request, email info@SiricaTx.com, call (650) 239-0646, or use https://www.siricacenter.com/contact. We will verify requests as required. An authorized agent may submit a request with proof of authority. You may appeal a decision where applicable by contacting us.

In the preceding 12 months, Sirica may have collected the categories described in Section 2, used them for the purposes in Section 4, and disclosed them to the recipient categories in Section 6.

12. Children’s privacy

The Site is directed to adults. We do not knowingly collect personal information online directly from children under 13 without verifiable parental consent when required. Parents or legal guardians may provide information about minors in connection with inquiries or services. If you believe a child submitted personal information without appropriate authorization, contact us so we can review and take appropriate action.

13. External links and third-party services

Third-party sites and services have their own privacy practices. This Policy does not apply to information a third party collects for its own purposes. Review their notices before providing information.

14. Changes to this Policy

We may update this Policy from time to time. We will post the updated Policy and revise the “Last updated” date. We will provide additional notice or obtain consent when required by law.

SMS Consent

​

SMS Appointment Reminder Program

By checking the SMS consent box and providing your mobile number, you expressly consent to receive recurring SMS text messages from Sirica Therapeutics Inc., doing business as Sirica Center and/or Sirica, at the number provided for appointment reminders. Messages may be sent using an automated system. Message frequency varies based on your appointments. Consent to receive SMS messages is not a condition of purchasing or receiving services. Message and data rates may apply. Mobile carriers are not liable for delayed or undelivered messages.

​

Opt out and help

Reply STOP to any message to revoke consent and stop texts. You may also contact us at info@SiricaTx.com or call (650) 239-0646. After you opt out, we may send one final confirmation message. Reply HELP for help or contact us using the information below. We will honor reasonable revocation requests made through other methods as required by law.

 

Privacy and message content

SMS is not a fully secure communication method. Appointment reminders may reveal that you have a relationship with Sirica to anyone with access to your phone or message notifications. We will limit message content and will not include detailed diagnoses, therapy notes, or payment-card information. Protect access to your device and notify us if your number changes or is reassigned. We use your mobile number and consent records to administer appointment reminders, document your preferences, and comply with law. We may share this information with service providers that deliver messages on our behalf, subject to appropriate restrictions. We do not sell SMS consent or mobile-number information to third parties for their marketing. See our Privacy Policy at https://www.SiricaTx.com/privacy-policy.

 

Eligibility

You must be 18 or older and the subscriber or customary user of the mobile number, or otherwise authorized to consent. A parent or legal guardian may enroll a number to receive reminders concerning a minor’s appointment.

 

Program changes

We may suspend or end the SMS program or change these terms. Material changes will be communicated as required by law. Your consent applies only to Sirica appointment reminders and does not authorize marketing texts.

​

SMS Opt-In Data and Consent

Notwithstanding anything else in this Privacy Policy, text-messaging originator opt-in data and consent—including mobile telephone numbers, SMS enrollment records, and messaging preferences—will not be sold, rented, transferred, shared, or disclosed to third parties or affiliates for their marketing or promotional purposes.

SMS opt-in data and consent are not transferable and will not be shared with another party based on consumer consent. Any general provision in this Privacy Policy permitting the disclosure of personal information with the consumer’s consent does not apply to SMS opt-in data or consent.

SiricaTx may use a contracted messaging service provider solely to transmit appointment reminders on SiricaTx’s behalf. Such a provider may process SMS information only as necessary to provide those services and may not use, sell, share, or disclose the information for its own purposes or for the marketing or promotional purposes of any third party.
