Essential
Session (NextAuth), language, and theme. Always on — without them you cannot stay signed in.
Analytics
Google Analytics (anonymized IP). Helps us see useful pages, approximate country, and whether sign-up works. We do not sell your data.
What are cookies
Small files or browser data (sometimes localStorage) that keep you signed in, remember theme, or measure site use in aggregate.
Essential cookies and data
NextAuth session cookies, light/dark theme preference, and interface language. Required for the site and your account to work.
Analytics (optional)
We use Google Consent Mode v2: analytics_storage, ad_storage, ad_user_data, and ad_personalization default to denied. If you accept the banner — or when you sign in — we grant analytics only (anonymized IP). We do not run Google Ads or remarketing. You can turn it off below anytime.
Sign-in and consent
When you create an account or sign in on chinesetrainer.com, we treat that as acceptance of anonymous product analytics to improve the experience. If you only browse without an account, the banner lets you accept or reject. On Android we use Firebase Analytics under Google Play policies.
How to manage them
Use the buttons on this page, the cookie banner, or clear site data in your browser. If you disable essential cookies, sign-in will stop working until you allow them again.
