Hanjjok Data Deletion Guide

Last updated: October 22, 2026

Hanjjok is an app you use with no sign-up and no sign-in. There is no account to delete, and this page explains where your data is and how to remove it.

1. This service has no accounts

The documents you open, the converted output, and your settings are all stored only inside your device. The Company operates no server and does not store users' documents.

2. Deleting data from your device

A single document: delete it from the app's document list (the copy held in the app is deleted)
Everything: delete the app and all documents and settings stored in it are removed

3. Information the Company holds, and deletion requests

The only information the Company receives is the email inquiries you send (address and content). If you would like it deleted, please ask at the contact point below. We destroy it without delay.

4. Information processed by third parties

Advertising identifier (Google) — you can reset your advertising ID or opt out of personalized advertising in your device settings (Android: Settings → Google → Ads).
Error diagnostic information (Sentry) — collected only when an error occurs; document contents, file names, and paths are masked before transmission. It is deleted automatically 30 days after collection.
Inquiry emails (Mailgun) — inquiries sent by email and the Company's reply emails pass through Mailgun (United States). The message body is not stored with Mailgun but only in the Company's mailbox (server in Seoul, Republic of Korea). Processing records (sender and recipient addresses, subject, time, and processing result) may remain with Mailgun for up to 30 days under Mailgun's retention policy. Deletion of inquiries kept in the Company's mailbox is handled on request under 3. above.

5. Paid product purchase records

The record of an ad-removal purchase belongs to the Apple App Store or Google Play account that processed the payment. Deleting the app does not cancel the purchase, and you can re-apply it after reinstalling through Settings → Restore purchase. Deletion of purchase records is governed by each app market's policy.
