What happens to your files
The results (your marked copies and the case file) are kept for 24 hours, or until you press delete, and are then removed. Do not upload anything you would not want kept.
Keys and names
The secret key for a job is created for that job. It is in the results for the same limited time and in the case file you download. It is not stored after that, so the service cannot recover it. The names you type are put in the case file and are removed with the rest of the job.
Accounts, cookies, logs
There are no accounts. This site sets no cookies of its own. Your address is held in memory while a job runs, to limit each person to one job at a time, and is not written to disk by the application. The service is configured not to keep access logs; the hosting provider's network may log connections under its own policy.
Advertising
This site may show advertisements served by third parties. They can set cookies and see your address and the page you are on, under their own policies. They never see your files, which are not part of the pages they appear on.
