Key Ddal — Terms of Use

Version: 1.0.0

Effective date: September 7, 2026

1. Service and eligibility

Akra Dev provides Key Ddal for keyboard sounds, typing, and item collection. Users must be at least 13 and meet applicable local requirements, including guardian consent where required. Contact: help@akra.kr.

2. Local data and use

Progress is stored on your device. Clearing data, uninstalling, or changing devices may cause loss of progress; account-based recovery and cross-device synchronization are not provided. Type input is not published or sent to other users.

3. Virtual items, ads, and purchases

Virtual currency and items support app features and carry no cash value, cash-out, or transfer rights. Rewarded ads are optional and grant the stated reward after a confirmed completion. New in-app purchases are currently disabled. If purchases become available, prices and conditions will be shown before payment; Google Play payment/refund procedures and applicable consumer rights apply.

4. Misuse and intellectual property

Do not violate law, exploit vulnerabilities, manipulate payment or reward records, infringe others’ rights, or disrupt the service. Rights in the app and supplied content belong to their respective owners. Do not redistribute or sell them without permission except as permitted by law.

5. Changes, maintenance, and updates

Features and content may change. We may temporarily restrict features or require updates to address incidents, maintenance, or safety concerns. Significant changes or closure will be announced in the app or on the support page where practicable. Use may be restricted until a required update is installed.

6. Responsibility and contact

Uninterrupted service and permanent data retention are not guaranteed. These terms do not limit consumer rights or liabilities that cannot legally be excluded. Contact help@akra.kr first with questions or disputes. Changes to these terms will carry a version, effective date, and notice.
