What you can review
Organize records into a readable report
02
Review available report items
Camera, microphone, keyboard-interface and uninstalled-app records depend on the file and analysis option. A keyboard event does not reveal typed text.
03
A report you control
Preview and export a PDF, or revisit, rename, share and delete reports saved on your device. Original archives and report content are not uploaded to us.
Getting started
Four steps from file to report
- Preview a sample
Open the anonymous report sample in the app to see how results are presented.
- Choose your diagnostic file
Follow the in-app guide to save a complete sysdiagnose archive, then select it from Files.
- Check before purchasing
Check the file format and readability, review the analysis option, then decide whether to buy a report credit.
- Generate and review
A credit is consumed after a report is generated successfully. Keep an original archive if you need to revisit the source records.

What records can tell you
Seconds in a timestamp do not mean complete coverage. Missing records do not rule out an event, and activity records alone do not establish who used the phone. Analyze only your own files or files you are explicitly authorized to review.
Common questions
Can I recover any date?
No. Available dates depend on what the system retained in the selected file. There is no fixed retention period or guaranteed coverage.
Does it prove someone read my messages?
No. Activity records do not establish the operator, which messages or photos were viewed, or whether private content was disclosed.
Is every feature included in every report?
No. Available sections depend on the diagnostic file and selected analysis option. Review the items and purchase details in the app.
Do I have to upload my files?
No. You select the archive and analysis runs locally. The app does not upload original archives or report content to us.
