MaskOff guide
Export call logs and evidence reports
Export all identified calls—or calls from one specific number—as a timestamped PDF or CSV file.
Choose the calls you need
MaskOff lets you export your complete identified-call history or limit the report to calls from one specific number. That makes it easy to document a repeated pattern without including unrelated calls. Each exported call record includes its timestamp and the phone number MaskOff identified behind the blocked call.
CSV for the raw call log
Choose CSV when you need the underlying call-log data in a simple, portable format. A CSV can be opened in spreadsheet software, shared with an investigator or attorney, or used to sort and review a larger history. It is the best choice when someone needs the data itself rather than a formatted report.
PDF for a clear evidence report
Choose PDF when you need a readable report to share with law enforcement, an attorney, or a court. The PDF organizes the selected call records and explains MaskOff's identification methodology so the recipient can understand how the information was produced. MaskOff PDF reports have previously been accepted as evidence in US court proceedings.
Support with authentication
Our team is available to explain the methodology and work with you or your attorney if authentication is needed. Acceptance always depends on the court, the case, and the applicable rules of evidence, so MaskOff cannot guarantee that a particular report will be admitted or what weight it will receive.
Preserve the surrounding record
Keep the original PDF or CSV unchanged after export. Preserve related messages, voicemails, screenshots, notes, and lawful recordings separately so it remains clear what MaskOff generated and what you added. If you are preparing for a legal proceeding, ask your attorney whether the court requires a particular filing or preservation process.
