Privacy Policy

Effective July 25, 2026

The short version

BrainJong is built to be private by design. There are no accounts, no sign-ups, and no advertising. Your games, scores, and progress live on your own device.

What we collect

Nothing on our servers. BrainJong does not operate accounts and does not transmit your gameplay, progress, or personal information to us.
On-device data. Your scores, trophies, streaks, saved hands, and settings are stored locally on your device (and in your device backups, which you control).
Purchases. Memberships are processed entirely by Apple through the App Store. We never see or store your payment details. Apple provides us anonymized transaction records so the app can unlock your membership.

What we don't do

No ads, and no advertising trackers.
No sale of personal information, to anyone, ever.
No third-party analytics SDKs harvesting your behavior.

Apple services

Standard Apple services the app uses are governed by Apple's Privacy Policy:

App Store purchases — membership payments are handled entirely by Apple.
iCloud sync — your progress and records are mirrored to your own iCloud account so they follow you across your devices. This data lives in your Apple ID, not on our servers.
Game Center (optional) — if you sign in to Game Center, your leaderboard scores are submitted to Apple's Game Center and may be visible to other players, and friend-table matches are relayed through Apple's Game Center service. Skip Game Center sign-in and the app plays fully without it.
Siri Shortcuts and Live Activities — only if you enable them.

Children

BrainJong is designed for adults and seniors and is not directed at children under 13.

Changes

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