Sallyport Privacy Policy
Effective 11 November 2026
In short: Sallyport doesn't collect your data. It works entirely on your Mac. It has no account, no analytics and no advertising, and it doesn't send anything about you or your network connections to us or to anyone else.
What Sallyport looks at
To apply your rules, Sallyport's network extension looks at each new network connection on your Mac:
- which app made it, and that app's code signature (its developer and whether it's signed by Apple);
- the destination's host name, IP address and port, and the protocol (TCP or UDP).
It also reads the answers to your Mac's unencrypted DNS lookups, so it can show and match the host name of a connection that goes to a bare IP address. It doesn't read the content of any other traffic.
What Sallyport stores, on your Mac only
- Your rules and settings.
- A list of recent connections (the last 500), held in memory and cleared when the network extension restarts.
- Recent DNS answers, held in memory for up to a day.
- Display preferences, such as where alerts appear.
- Diagnostic messages in macOS's system log, such as the name of an app when you answer an alert. These stay on your Mac unless you choose to share a system report with someone.
What leaves your Mac
Nothing. Sallyport makes no network connections of its own and has no servers. If you export your rules, the file is saved wherever you choose, and goes nowhere else.
Deleting your data
In Sallyport, choose Settings → Advanced → Uninstall…, then Uninstall, Delete Rules. This removes the network extension along with your rules and settings.
The App Store
Apple handles purchases and downloads, under Apple's privacy policy. If you've chosen to share analytics with app developers, Apple gives us anonymous, aggregated figures such as install counts and crash reports. We can't identify you from them.
This website
How kilnfox.cc itself handles visits (no cookies, no analytics) is described on the website privacy page.
Children
Because we don't collect personal information from anyone, we don't knowingly collect it from children.
Changes
If this policy changes, we'll update this page and the date at the top before the new version of Sallyport is released.
