Privacy policy

1. Information we collect

When you sign in with Google OAuth, Dallim may collect:

• Your email address
• Basic identifiers associated with your Google account

We may also store races you save and races for which you enable registration alerts.

If you request a registration alert without signing in, we store only the email address you enter and the race associated with that alert.

2. How we use information

We use collected information only to:

• Sign you in and identify your account through Google
• Save favorite races and registration alert settings
• Verify ownership and consent for email alerts requested without an account
• Send an email before race registration opens
• Diagnose service errors and maintain reliable operation

3. Retention

We retain account information until you close your account or request deletion. When you turn off a registration alert, its alert setting is deleted immediately.

Email alert information submitted without an account is deleted when you unsubscribe or during operational cleanup after the relevant race has ended.

4. Third-party services

Dallim relies on the following providers. Each provider may process only the information required for its role.

• Supabase: authentication, database storage, favorites, and alert settings
• Resend: confirmation emails and registration-opening alerts
• Vercel: website hosting and deployment

5. Affiliate links and advertising

Dallim may include affiliate links from services such as Coupang Partners and AliExpress. Dallim may receive a commission when a user purchases through one of these links. This revenue helps cover the cost of operating the service.

6. Your rights

You may request access to, correction of, deletion of, or restriction of processing of your personal information. Send requests to:

hello@dallim.co.kr

7. Policy changes

Changes to this privacy policy will be posted on this page. We may also provide notice in the service or by email when a change is significant.
