Privacy

Knight Graph was built to collect nothing about you. In short: we don't gather, store, or share any personal data.

What we collect

Nothing. The app has no accounts, no sign-in, and never connects to a server of ours. There is no such server.

What stays on your iPhone

Everything you create or import — your sets, your puzzle PGNs, your progress, your stats, and your settings — is stored only on your device. If you export a backup from Settings → Data, that file is yours to keep wherever you choose.

PGN import

When you import a PGN file, it is processed entirely on your iPhone. It is never sent anywhere.

Third parties and tracking

The app contains no analytics, no advertising, and no tracking SDKs of any kind. We use no cookies and no identifiers. There is nothing to profile.

App Store

Apple may collect data about your download under its own privacy policy. We have no access to information that identifies you.

Children

Because the app collects no data from anyone, it collects no data from children either.

Changes

If this policy changes, the updated version will be posted on this page with a new date.
