Privacy policy
Effective Nov 15, 2026
What we collect
Without signing in, we collect no account data. When you sign in with Google, we receive the email address, name, profile photo address and account ID that Google sends. We add the nickname you choose, and a record of your cheers, favourites, playlists, the fancams you suggest or rate, and the suggestions you post. Suggestions are seen only by you and the operator.
Why we use it
Only to keep you signed in, to show your favourites, playlists and suggestions, and to stop one person from taking part many times. Your email, name and profile photo are never shown to other users and never used for ads.
Keeping and deleting
We keep the data while your account exists. Leaving from the My account page deletes your account and activity right away. Fancam links a fan submitted may stay without any link to that person. You can also ask by email.
Who processes it
Accounts and activity are handled by Supabase (database and sign-in, Seoul region), delivery and access logs by Vercel (hosting), and sign-in by Google. These companies are based abroad, so data may be processed outside Korea.
Stored on your device
Your sign-in state, a copy of your favourites, and a random device number used for cheering without signing in are kept in browser storage. When you cheer without signing in, we keep that device number and a one-way hash of your network address, only to stop floods of cheers from one network. Visit statistics count only which pages were viewed, where visits came from (search, social and so on) and which features were used, as daily totals. You can turn statistics off in Cookie settings. To count each device once a day, the device number is stored as a one-way hash for up to 90 days and is never linked to an account or network address. We use no advertising or tracking cookies.
YouTube
Videos play in the YouTube player, and some video details come through YouTube API Services. When you use videos, the YouTube Terms of Service and the Google Privacy Policy also apply.
Age
Sign-in is not available to anyone under 14.
Your rights and contact
To see, correct or delete your data, use the My account page or write to the address below. If this policy changes, we will say so on this page first.
