Data Deletion

Effective date: 2026-10-12 (UTC+09:00)

1. Account and Study Information

There is no separate app account to delete. Learning records, settings and card text are stored on your device. Check which records you will lose before deleting data. The operator cannot remotely delete records stored only on your device.

2. iPhone/iPad

To remove the app's data on your device, use 'Delete App' in iPhone/iPad Settings' app storage management. 'Offload App' is different from deletion, since data may remain. Check what study records you'll lose before doing this. Data left in backups and cards saved to your photo library must be managed separately.

3. Android and Web

On Android, you can delete the app's data from the app storage section of your device settings; menu names vary by device. For the web preview, use your browser's site-data deletion feature. Please check the target carefully so you don't delete data from other sites.

4. Copies and Purchases That Aren't Deleted

Copies in your photo library, apps you shared to, or OS backups need to be deleted separately. Deleting app data does not mean your store purchase history is deleted or refunded. Some information may reappear after reinstalling or restoring from a backup.

5. Information You've Given the Operator

To delete information submitted through an application, feedback, or email inquiry, contact hanguldot@gmail.com. Use “Hangul Dot personal data deletion request” as the subject and identify the email used and the information to delete. We request only the minimum information needed to verify the request; do not send passwords or identity documents unsolicited. Learning records stored only on your device cannot be deleted remotely. We will email you the outcome or any request for further verification.

You may also request deletion of purchase-related personal data at hanguldot@gmail.com. If you purchased, provide the store and relevant order number so the operator can locate the linked RevenueCat customer record, subject to minimum identity verification. Hide unrelated orders and payment information. Non-purchasers may also make a request, but the app currently has no support-ID display; email alone may not identify an anonymous App User ID or device identifier. We explain what can be identified and what needs further verification. Uninstalling, reinstalling or restoring purchases is not a personal-data deletion method. The scope and impact of any action that could affect purchase access are checked first.

For correction or deletion requests, we notify you of the legally required result within 10 days of receipt. If deletion is restricted by law, we explain the reason and how to object. Completed actions and information requiring supplier confirmation are distinguished; unverified deletion is not reported as complete. This is not a promise to fully erase every supplier backup within the same period.

The operator verifies the requested records and your identity using only the information needed, and identifies any records that must be retained by law. For operator-managed data to be deleted, the operator checks the relevant database, pending transmissions, mail and attachments and handles deletion; where external service action is needed, the operator requests it. You are informed of the outcome and any limits and reasons. This does not mean automated deletion exists or that existing records have already been deleted.

Moving mail to Trash is different from permanent deletion, so the status of the selected messages is distinguished. Database deletion also includes reviewing residual-data cleanup; when restoring a backup, previously handled deletions are reapplied. Backups currently exist, and immediate erasure of every supplier copy is not guaranteed.

Please send personal data deletion requests first to hanguldot@gmail.com. The Hangul Dot operator receives and handles your request and coordinates with RevenueCat when needed. RevenueCat, Inc. provides compliance@revenuecat.com as an additional privacy contact. This additional contact does not replace the Hangul Dot operator’s responsibility to receive and handle your request.
