Privacy Policy

Privacy Policy

Effective date: October 20, 2026 · Applies to the iOS app “Principles · 原则” by Sapjax

Short version

We do not collect, transmit, or sell any of your personal data. There is no account, no analytics, no advertising, and no third-party tracking SDKs in this app.

Where your data lives

• On this device. Principles you write are stored locally in the app's database.
• Your own iCloud (optional). If you are signed in to iCloud, your principles sync privately through Apple's CloudKit service inside your personal iCloud account. We never see this data; it stays between your devices and Apple's servers under your Apple ID.

Purchases

The one-time unlock is processed entirely by Apple through the App Store. We receive no payment details and no personal information about the buyer; entitlement is verified on-device through StoreKit.

What we never do

• We do not collect your name, email, location, contacts, or usage analytics.
• We do not transmit your principles to any server operated by us.
• We do not include advertising or third-party data-collection SDKs.

Deletion

Delete a principle in the app to remove it from the device. Data mirrored to your personal iCloud is managed by Apple under your Apple ID and is removed when deleted from the app. Uninstalling the app removes local data.
