  • Article 6(1)(c) โ€” Legal obligation: Processing required by law (e.g., financial record-keeping, responding to lawful requests from authorities).
  • Article 6(1)(f) โ€” Legitimate interests: Processing for our legitimate business interests (fraud prevention, security, service improvement, sending service-related communications), provided these do not override your rights and interests.
  • Article 6(1)(a) โ€” Consent: Processing based on your freely given, specific, informed consent (e.g., marketing emails, non-essential cookies). You may withdraw consent at any time without affecting the lawfulness of processing prior to withdrawal.
Section 06

Data Sharing & Disclosure

All data processors are bound by Data Processing Agreements (DPAs) and are required to implement appropriate technical and organisational security measures.

6.2 Affiliate tracking

Where you arrive at BookWalker via an affiliate or advertising partner, we may transmit a click identifier (a pseudonymous tracking code assigned by the advertising network) to our affiliate tracking system to attribute your subscription to the correct marketing campaign. This transmission occurs server-side and does not include your name, email address, or any payment data. The legal basis for this processing is our legitimate interest in measuring advertising effectiveness (GDPR Art. 6(1)(f)).

6.3 Advertising measurement (Meta Pixel)

We use the Meta (Facebook) Pixel on our checkout page for advertising measurement purposes. The Pixel is only loaded if you have given your consent via our cookie consent banner. If you select "Necessary only", the Pixel is not loaded and no data is sent to Meta. The legal basis for this processing is consent (GDPR Art. 6(1)(a)).

6.4 Legal Disclosures

We may disclose personal data to competent authorities, courts, or regulators where required by applicable law, a court order, or to protect the rights, property, or safety of VINIKIS LTD, our users, or others.

6.5 Business Transfers

In the event of a merger, acquisition, or sale of all or substantially all of our assets, personal data may be transferred to the acquiring entity, subject to equivalent privacy protections. We will notify affected users as required by law.

Section 07

International Data Transfers

As a UK company serving EU and US users, personal data may be transferred outside the UK and European Economic Area. Where such transfers occur, we ensure adequate safeguards are in place:

  • EU-UK adequacy decision: The European Commission has adopted an adequacy decision for the UK (Decision 2021/1772), permitting data flows from the EEA to the UK.
  • Standard Contractual Clauses (SCCs): For transfers to third countries (e.g. the USA), we rely on EU Standard Contractual Clauses (2021/914/EU) and UK International Data Transfer Agreements (IDTAs) as appropriate.
  • Adequacy decisions: Where applicable, transfers are made to countries with an EU or UK adequacy decision.

The Service is not directed at children under the age of 18. We do not knowingly collect personal data from minors. If you are a parent or guardian and believe your child has provided us with personal data, please contact [email protected] immediately. We will delete such data without undue delay.

Section 13

Security

We implement appropriate technical and organisational security measures to protect your personal data against unauthorised access, alteration, disclosure, or destruction. These include:

  • Password storage using bcrypt with a high cost factor;
  • Access controls limiting data access to authorised personnel only;
  • Regular security reviews of our infrastructure;
  • Payment data handled exclusively by PCI-DSS compliant processors.

No method of electronic transmission or storage is 100% secure. In the event of a data breach that poses a risk to your rights and freedoms, we will notify the relevant supervisory authority within 72 hours and notify affected individuals as required by law.
