Q. Are there any ads?
A. No. The App does not include any advertising SDK.
Q. Where is my data stored?
A. Entirely on your device. The App performs no network communication and does not submit test reports anywhere — it is a records and PDF-generation tool, not an electronic submission service.
Q. How do I delete my data?
A. Delete individual customers, assemblies, or tests within the App, or uninstall the App to remove all data stored on your device.
Q. Are there any in-app purchases?
A. The App is free to download with a 7-day full-access trial. After the trial, a one-time purchase (non-consumable, no subscription) unlocks new customer/assembly/test entries and PDF report generation. Viewing existing records is always free.
Q. Does the App decide whether an assembly passes or fails?
A. No. The tester always chooses the pass/fail result. The App only records what you enter and lays it out on the PDF report.
