Recording of additional information: Generation of JSON file with call details (phone number, name from address book, date, time, duration, call status). Assigned audio file for each call.

File organization: Storage in a dedicated folder, encrypted audio and JSON files with names including user's phone number, call date, caller number.

File transfer: Cyclic compression and file transfer to a secure REST API. Ability to manually trigger the upload. Deletion of files after upload.
