2. Troubleshooting Common Inquiries

• Restoring Previous Purchases

If you bought Cairn Harmony Plus (Monthly Plan, Annual Plan or Lifetime Pass) and reinstalled the app or moved to a new iPhone:

Open Settings inside Cairn Harmony and tap Cairn Harmony Plus.
Tap "Restore Purchases".
Make sure you are signed in with the same Apple ID used for the original purchase.

• iCloud Sync (end-to-end encrypted, Plus)

iCloud sync is part of Cairn Harmony Plus. Records are encrypted on your iPhone and stored in your own private iCloud (CloudKit) database. The encryption key is kept in your iCloud Keychain and can be protected with an optional passphrase. iCloud Drive is not needed.

Make sure you are signed in to iCloud and that iCloud Keychain is on (iPhone Settings > [your name] > iCloud > Passwords and Keychain).
Turn on sync in Cairn Harmony: Settings > iCloud sync.
Make sure there is free space in your iCloud storage.
On a new iPhone, sign in with the same Apple ID, open Cairn Harmony and turn on sync. If you set a passphrase, you will need it to unlock the synced data.
Data read from Apple Health is never synced; it stays on each iPhone.
iPhone and iPad: use the same Apple ID and turn on sync in the app on both devices. Data goes only between your devices and your own iCloud; we have no servers and never store it. Cairn Harmony runs on iPad in iPhone compatibility mode.

• Receipt scanning (camera)

Tap the scan button in the amount field when adding an activity or a transaction. The receipt is read on your iPhone and the photo is not saved. If the camera does not open, go to iPhone Settings > Cairn Harmony > Camera and turn access on. If the total cannot be read, tap "Scan again" or type the amount yourself, and always check a scanned amount before saving.

• Apple Health (HealthKit) Access

Cairn Harmony only reads from Apple Health (for example sleep, workouts and active minutes) and never writes to it. To grant or change access, go to iPhone Settings > Health > Data Access & Devices > Cairn Harmony.

3. Managing Subscriptions & Cancellations

All in-app purchases and subscriptions are handled securely through Apple App Store services. You can manage or cancel your subscription at any time:

Open the App Store app on your iPhone.
Tap your profile avatar in the upper-right corner.
Tap Subscriptions > Select Cairn Harmony > Tap Cancel Subscription.
