Privacy policy: Pairfold

Last updated: 13 November 2026

This page covers Pairfold, both the Mac App Store version and the download from kayabyte.dev. Kayabyte’s general policy for the Mac apps is at kayabyte.dev/mac/privacy; where the two differ, this page applies to Pairfold.

Short version

Pairfold collects no data about you. The App Store version sends nothing anywhere; its privacy label says Data Not Collected. The download from kayabyte.dev goes online only to check your licence key and for updates, as described below.

What Pairfold reads and writes

Pairfold reads and writes only the folders you choose in the app, and the archive folder you set. Its settings, run history and log are stored on your Mac inside the app’s container (~/Library/Containers/dev.kayabyte.mac.pairfold). They never leave your Mac unless you export the log yourself.

Network

The App Store version has no network access of its own. Both versions talk to a network share only as a folder you mounted in Finder and chose in the app. There is no account, no analytics, no crash reporting, no advertising and no tracking.

The download from kayabyte.dev makes two kinds of requests, nothing else:

• Licence check. When you enter a licence key, and about once a day after that, the app sends the key, the app name and a device code to our licence service, so a key works on up to 2 Macs. The device code is a one-way hash made on your Mac; it does not contain your name, serial number or files. Details are in the Mac apps privacy policy.
• Updates. The app reads kayabyte.dev/mac/pairfold/appcast.xml to see whether a new version exists (you can turn the automatic check off in Settings). No system profile is sent.

Purchases

On the Mac App Store, Apple handles the payment and we do not receive your payment details; Apple’s privacy policy applies. A licence for the download is sold by Paddle.com, our Merchant of Record: Paddle handles the payment and sends us the email address and order details we need to issue and support your licence key.

Support email

If you write to support@kayabyte.dev, we use your email only to answer you and delete the conversation when it is no longer needed.
