Data is collected through:

The lawful basis for collecting this data is legitimate interest of the venue which is the data owner. Both Bookline and the reservation software partner, when it applies, act as subprocessors.



Bookline ensures the protection of personal data through a combination of advanced cybersecurity measures and compliance with data protection regulations. We adhere to the NIST Cybersecurity Framework, which guides our security practices and policies.

We've implemented multiple layers of protection such as:


  • Data encryption: All data, both at rest and in transit, is encrypted using industry-standard encryption algorithms.
  • Regular security audits: We conduct periodic security audits and vulnerability assessments to identify and rectify any potential weaknesses in our system with an external provider.
  • Access control: Strict access controls are in place, ensuring that only authorized personnel can access sensitive data. We use a principle of least privilege, granting access only when necessary and only to the extent required for job functions.
  • Incident response plan: In the unlikely event of a security breach, we have a robust incident response plan in place to quickly address and mitigate any risks.
  • Backup and recovery: Regular backups are conducted, and data recovery plans are in place to ensure business continuity and data integrity.
  • Continuous monitoring: Our systems are continuously monitored for any suspicious activities, and alerts are set up to notify us of any anomalies.
  • Security training: All our staff undergo regular security training to ensure they are aware of the latest threats and best practices to prevent potential breaches


Our approach to data retention is crafted to strike a balance between operational efficiency and the utmost respect for user privacy. We are committed to ensuring that personal data is processed responsibly and stored for only as long as is strictly necessary.


  • User Information
    • Identification Data: While we process identification data such as name, phone number, and email address during interactions, this data is not stored in our systems post-processing.
    • Preferences: Similar to identification data, preferences are processed to offer a tailored experience during interactions but are not stored in our systems once the session concludes.
  • Reservation Details
    • Special Requests: Special requests related to reservations are retained until 2 months post the reservation date. This period allows us to assist venues with any inquiries or issues related to past interactions, ensuring a seamless experience for both users and venues.
  • Voice Interaction Data
    • Transcriptions: We store transcriptions from voice interactions, but any personal data within these transcriptions is rigorously redacted to ensure user privacy. It's important to note that these redacted transcriptions are not used for machine learning purposes. Our system's learning process is supervised by a dedicated tech engineer and is exclusively done using transcriptions that are devoid of personal data.
