A: Thank you for your concern regarding the security of contact data in ContactBook. We want to assure you that protecting your information is our top priority.

ContactBook is built using a secure three-tier architecture, which separates the user interface, application logic, and data storage to minimize risk and ensure strong data protection. All contact data is stored in Amazon RDS (Relational Database Service), where it is encrypted at rest using industry-standard encryption protocols.

Our database is hosted in a secure, private environment that is not directly accessible from the public internet. Only authorized components of our application can access it through tightly controlled security configurations.

Importantly, we do not sell or share any customer data with third parties, and there is no direct way to download data from our database. Internal access to customer information is strictly limited to authorized personnel for support or maintenance, and all access is logged and monitored.

We are fully committed to keeping your data safe and private, and we continuously review and improve our security practices to maintain that commitment.

If you have any further questions or require additional details, we’re happy to help.
