6. Enable automatic cloud backup (if available): This protects your files against loss or device failure.
7. Perform preliminary tests in different environments: Test in quiet locations and environments with moderate noise to calibrate the ideal sensitivity.
8. Protect your files with a password or biometric authentication: If the app offers encryption or password protection, enable it immediately.

In professional settings, extra caution is needed, especially when there are internal privacy policies.
