4. Legal Bases for EEA and UK Users

If the EU GDPR or UK GDPR applies, we process personal data only when a lawful basis is available. Depending on the activity, the lawful basis may include:

Contract: processing necessary to provide a product or service you request or to take steps at your request before entering into a contract.
Consent: for example, where consent is required for marketing communications or non-essential cookies/technologies. You may withdraw consent at any time without affecting processing already carried out lawfully.
Legitimate interests: such as operating and securing the Services, preventing fraud, understanding use of our products, improving our offerings, and conducting appropriate direct marketing, where those interests are not overridden by your rights and interests.
Legal obligation: processing needed to satisfy applicable tax, accounting, consumer protection, regulatory, or other legal requirements.

5. Email Marketing and Your Choices

If you sign up for a free book, newsletter, promotion, or other offer, we may send emails consistent with the notice and choices presented at signup and applicable law. Marketing emails will provide an unsubscribe method. Transactional or service communications relating to an order, account, security matter, or request may still be sent when necessary.

For users in jurisdictions where prior consent is required for electronic marketing, Castles and Kingdoms, LLC, through GuruBooks, will rely on an appropriate lawful basis and consent mechanism before sending marketing communications.

6. Cookies, Analytics, and Advertising Technologies

Our website may use cookies and similar technologies for essential operation, security, preferences, analytics, and advertising or measurement. Where applicable law requires consent before using non-essential cookies or similar technologies, those technologies should remain disabled until the visitor provides the required consent through the site’s consent mechanism.

Your available choices may include a cookie banner or privacy settings tool, browser controls, and recognized opt-out preference signals where required by law. Because the specific cookies and third-party technologies can change, Castles and Kingdoms, LLC, through GuruBooks, should maintain an up-to-date cookie disclosure or cookie settings interface describing the categories and purposes of technologies in use.

7. How We Disclose Personal Information

We may disclose personal information to the following categories of recipients as necessary for the purposes described in this Policy:

Website hosting and site-service providers, including Wix.
E-commerce, digital-delivery, and payment providers, including Payhip and Stripe.
Advertising, lead-generation, and social-media platforms, including Meta, where used.
Email delivery, customer communications, analytics, security, fraud-prevention, professional advisory, accounting, and IT service providers.
Government authorities, regulators, courts, law enforcement, or other parties when disclosure is required by law or reasonably necessary to protect rights, safety, property, or the integrity of the Services.
A buyer, investor, successor, or other relevant party in connection with a merger, financing, acquisition, reorganization, sale of assets, or similar business transaction, subject to appropriate safeguards.

We do not sell personal information for money. If our use of advertising or analytics technologies constitutes a "sale" or "sharing" under an applicable U.S. state privacy law, we will provide any legally required notice and opt-out mechanism.

8. Retention of Personal Information

We retain personal information for only as long as reasonably necessary for the purposes for which it was collected, including to provide Services, maintain business and transaction records, comply with legal and accounting obligations, resolve disputes, enforce agreements, prevent fraud, and maintain appropriate suppression records for people who unsubscribe. Retention periods vary according to the nature of the information and applicable requirements. Where feasible, information that is no longer needed is deleted, anonymized, or otherwise securely disposed of.

9. International Data Transfers

Castles and Kingdoms, LLC is based in the United States and operates the GuruBooks imprint. We use service providers that may process information in the United States and other countries. If personal data from the EEA, United Kingdom, or another jurisdiction is transferred to a country that does not provide an equivalent level of data protection, we will rely on an applicable legal transfer mechanism when required, such as an adequacy decision, approved standard contractual clauses, the UK International Data Transfer Agreement/Addendum, or another lawful safeguard. Service providers may also rely on legally recognized transfer mechanisms for their own processing.

10. Your Privacy Rights

EEA and United Kingdom

Subject to applicable law and exceptions, individuals may have rights to request access to personal data, correction, deletion, restriction of processing, data portability, and objection to certain processing. Where processing is based on consent, consent may be withdrawn. Individuals may also have the right to complain to the competent data protection supervisory authority in their country or region.

United States

Depending on your state of residence and whether the applicable law covers Castles and Kingdoms, LLC, you may have rights to request access to or confirmation of personal information, correction, deletion, or portability; to opt out of certain sales, sharing, targeted advertising, or profiling; and to appeal certain request decisions. California residents may also have rights to know categories and specific pieces of personal information, delete, correct, opt out of sale or sharing, limit certain uses of sensitive personal information where applicable, and receive equal service and pricing when exercising privacy rights.

Castles and Kingdoms, LLC will not discriminate against you for exercising a privacy right provided by applicable law.

11. How to Exercise Your Rights

To submit a privacy request, contact us at privacy@gurubooks.guru or through any privacy request method made available on GuruBooks.guru. Please describe the request and the jurisdiction in which you reside. We may need to verify your identity before completing certain requests. Authorized-agent requests will be handled as required by applicable law.

Where applicable law provides a right to appeal a decision concerning a privacy request, you may submit an appeal using the same contact method and state that the request is an appeal.

12. California Notice at Collection

At or before collection, California consumers should be informed of the categories of personal information collected and the purposes for which they are used. This Policy describes those categories and purposes in Sections 2 and 3. If Castles and Kingdoms, LLC becomes subject to additional California disclosure, opt-out, or annual-update requirements because of its scale or data practices, the Policy and point-of-collection notices should be updated accordingly.

13. Children’s Privacy

The Services are not directed to children under 13, and Castles and Kingdoms, LLC, through GuruBooks, does not knowingly collect personal information from children under 13 through the Services without legally required parental consent. If we learn that personal information from a child under 13 was collected in circumstances requiring parental consent and such consent was not obtained, we will take appropriate steps to delete it. Additional age and consent requirements may apply in the EEA, United Kingdom, and other jurisdictions depending on the service and legal basis involved.

14. Data Security

We use reasonable administrative, technical, and organizational measures designed to protect personal information against accidental or unlawful destruction, loss, alteration, unauthorized disclosure, or access. No Internet transmission or storage system can be guaranteed to be completely secure, so absolute security cannot be promised.

15. Third-Party Sites and Services

The Services may link to or integrate with third-party websites, platforms, payment processors, social networks, or other services. Their privacy practices are governed by their own policies. This Privacy Policy does not control the independent privacy practices of third parties.

16. Changes to This Privacy Policy

We may update this Privacy Policy from time to time to reflect changes in our practices, technologies, Services, legal requirements, or other factors. The effective date at the top will be updated when the Policy changes. If required by law, we will provide additional notice or obtain consent before materially different processing begins.
