Index Note

Privacy Policy

Effective date: November 8, 2026

Index Note (the "app") is a diary app for iPhone and iPad made by the developer of Pocket Korean. The app does not collect personal data. Below is where your records are kept and when they are exchanged with other services such as Apple.

1. Information the developer collects

  • The developer does not collect any personal data: no names, email addresses, device information or usage data.
  • The app has no ads, analytics or tracking, and the developer runs no servers for it.

2. Where your records are kept

  • Plans, diary entries, photos, handwriting, ledger entries, memos and settings are stored on your iPhone or iPad and are included in your device backups (such as iCloud Backup).
  • If you turn on Sync with iCloud in Settings, the same records are also stored in your own iCloud account (Apple's CloudKit private database) and kept in sync across devices signed in to the same Apple Account. The developer cannot see them.
  • Diary photos are saved as smaller copies; your originals stay in the Photos app.

3. The shared "Our ledger"

  • If you invite someone to "Our ledger", the entries in that ledger and the display name you choose are shared with the people you invite through iCloud (CloudKit sharing).
  • Your diary, plans, memos and "My ledger" are never shared. You can stop sharing in the app at any time.

4. Permissions the app asks for

  • Photos: only when you pick photos for your diary or ledger.
  • Camera: only when you take a photo or a receipt picture.
  • Calendars: only when you turn on iPhone Calendar in Settings, to exchange events with the Calendar app. Calendar data is not sent anywhere by the app (your calendar accounts sync as usual through Apple).
  • Notifications: event reminders and the evening diary reminder are scheduled on your device.
  • You can turn any permission off in iPhone Settings › Apps › Index Note.

5. Information exchanged with Apple and other services

  • Place names: if a photo contains location data, its coordinates are sent to Apple's map service to look up the place name. The app does not track your location.
  • Receipts: receipt text is read on your device with Apple's text recognition, and the photo is not kept.
  • Exchange rates: when you use several currencies in the ledger, today's rates are downloaded from a public exchange-rate service (api.frankfurter.dev). No personal data is sent, but as with any internet request, that service can see your IP address.
  • Purchases: the lifetime pass and Family Sharing are handled by Apple (App Store). The developer receives no payment information. To remember when your free trial began, one date is saved in your keychain (iCloud Keychain).

6. Deleting and exporting

  • In the app, Settings › Data lets you export your records to a file or erase them all.
  • Deleting the app removes the records on that device. Records in iCloud can be deleted in iPhone Settings › [your name] › iCloud › Manage Storage.

7. Children

  • The app collects no personal data from anyone, including children.

8. This website

  • The demo on this website runs only in your browser and does not save what you enter.
  • The website loads fonts from Google Fonts, and the hosting provider may keep standard access logs. No cookies or analytics are used.

9. Changes

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