Terms of Service

2026-07-06

This Terms of Service governs your use of DevTools Hub (tools.hellodev.kr, the "Service").

1. Service

The Service provides a free collection of online tools for developers. Most tools run entirely within your browser, while certain features — such as the ERD editor — require signing in with a Google account and store data on our servers.

2. Accounts

Account features are provided via Google OAuth, and the Service does not collect a separate password. You may delete your account and its associated data at any time by withdrawing your account. When you delete your account, your account and all saved ERD diagrams are permanently deleted immediately and cannot be recovered.

3. User Responsibilities

You may not store content that violates applicable laws, or engage in conduct that interferes with the normal operation of the Service, such as sending automated bulk requests.

4. Data and Limitation of Liability

The Service is provided "as is." As a free service, we do not guarantee the permanent preservation of stored data, so please use the export feature to keep separate backups of any important data. Except in cases of intent or gross negligence, the operator is not liable for damages arising from use of the Service.

5. Changes to These Terms

If these Terms change, the update will be posted on this page. For material changes, we may request your renewed consent at login.

6. Contact
