CDR ( Call Detail Record ) and private policies.

Question

Can you please tell me if the CDR calls made by me on Viber are captured by the local service provider (mobile operator company) or not?

Answer 1

These files are not kept by mobile operator company. Viber keeps these files and declares that CDR files are used to improve services. They also state that the analysis is done in non-personally manner. Anyway, these files are kept for a period not more than 30 months.
