K-Pop Heardle (“we”, “us”) is a free music-guessing game. This page explains what data we collect and how it is used. You can play the whole game without an account; creating one is optional and only adds cross-device stats.
Local storage
When you play without an account, your game progress, statistics, theme preference, and cookie choice are stored locally in your browser (via localStorage). This data stays on your device and is not transmitted to us.
Accounts
If you choose to create an account, we collect and store the information needed to run it: your email address, a username, an optional display name, and an optional profile picture you upload. Once signed in, your game results and statistics (scores, streaks, and guess history) are saved to our servers so they stay in sync across your devices.
If you played as a guest before signing up, we make a one-time copy of your existing local stats into your account as a separate “pre-account” record. It is clearly labelled as unverified and is never mixed into your account’s official stats.
Account data is processed by Supabase (authentication, database, and profile-picture storage) and Resend (sending verification, password-reset, and security emails). If you sign in with Google, Google shares your email address and basic profile with us to create the account.
Data retention & deletion
We keep your account data for as long as your account exists. You can delete your account at any time from your profile settings; this permanently removes your email, profile, and stored stats from our servers. You can also request deletion via the contact channels below.
Advertising
We display ads through Google AdSense to keep the game free. Google and its partners may use cookies and similar technologies to serve ads based on your visits to this and other sites. Where required, we ask for your consent before serving personalized ads; if you decline, we request non-personalized ads instead. You can learn more and manage your preferences at Google's Advertising page.
Analytics
We use privacy-friendly Vercel Analytics and Speed Insights to understand aggregate traffic and performance. These do not use cross-site tracking cookies and do not identify individual visitors.
Your choices
You can change your cookie choice at any time by clearing this site's data in your browser, which will prompt the consent banner again. You may also use your browser or Google Ad Settings to control ad personalization.
