Sharing is off until you turn it on. Once it is on, a run that passed every check is sent automatically, at most once a day, and you can send a single run yourself from its details. A shared run contains the Mac model, the chip, the graphics card, the number of cores, the memory, the macOS and app version, and the scores. It contains no name, no email address and no serial number. It is stored in the app's iCloud database, where iCloud adds an anonymous identifier that exists only for this app, so that results from the same person count once. Shared runs are never shown unreviewed: I look at them first, and only combined results appear in the comparison. The app loads that comparison from this website. Turn off sharing, the comparison and crash reports in the settings, and the app makes no requests at all. If you would like your shared results removed, get in touch.

On macOS 27 and later, an app that has crashed sends me a report, so that I can find and fix the problem. This is on by default, and you can turn it off at any time with "Send Anonymous Crash Reports" in the app's settings. A report contains the name and version of the app, the macOS version, the Mac model, the region format and technical details about the crash, such as where in the app's code it happened. It contains no name, no email address and no serial number. The report goes through this website into a database in the EU, both run on Cloudflare, and is used solely to fix problems. It is never shared with third parties. Your IP address is only used, in a form that cannot be traced back, to limit how many reports can be sent. Reports are deleted automatically after 12 months.

The contact form in my apps sends nothing until you press Send. It then sends your message, the topic you chose and the email address you enter for my reply, together with the app name and version, the macOS version, the Mac model and the app language. If you tick the box, the app's log of the current session is attached. The request goes through this website into a database in the EU, both run on Cloudflare, and is used solely to answer you. It is never shared with third parties. Your IP address is only used, in a form that cannot be traced back, to limit how many messages can be sent. Requests are deleted automatically after 12 months. If you would like yours deleted sooner, get in touch.
