Yearring Privacy Policy

Last updated: October 3, 2026

Yearring ("이어링", "年輪") is a habit tracker made by Seonghun Lee ("we"). This policy explains what happens to your information when you use the Yearring apps for iPhone, Apple Watch and Android.

The short version

Your habits stay on your device. We don't run servers for Yearring, we don't have accounts, and we don't use analytics, advertising or tracking SDKs.

Data stored on your device

• Habits you create (name, icon, color, schedule, goals, reminder time) and their history (check-ins, rest days, quit dates and restarts), plus your app settings.
• This data is stored only on your device (and on your paired Apple Watch, which receives a copy directly from your iPhone). It is included in your device's own backups (iCloud / Google) if you have those turned on; we cannot access them.
• Exporting creates a JSON file that you choose where to save or share.
• Deleting the app deletes this data.

Purchases

If you buy Yearring Premium, the payment is handled by Apple (App Store) or Google (Google Play). To check whether your purchase is active we use RevenueCat, Inc., which receives your purchase receipt and an anonymous app user ID generated on your device. We do not receive your name, email or payment details. See RevenueCat's privacy policy: https://www.revenuecat.com/privacy

Notifications

Reminders are local notifications scheduled on your device. Nothing is sent to us.

Children

Yearring is a general-audience app and does not knowingly collect personal information from anyone, including children.

Your choices

You can export, edit or delete your data at any time in the app. For purchase-related data held by RevenueCat, contact us and we will request its deletion.

Changes

If this policy changes we will update this page and the date above.
