Cookie Policy
Last updated: September 2, 2026
This Cookie Policy explains how Birthday Color Cafein ("we", "us", "our") uses cookies and similar technologies on www.birthdaycolorcafein.com. It works alongside our Privacy Policy and Terms of Service.
What are cookies?
A cookie is a small text file that a website saves on your device. Cookies make sites work, remember your preferences, and help measure traffic. Some cookies are set by the site you're visiting ("first-party"), while others are set by third-party services embedded in the page.
We also use localStorage, a browser storage mechanism similar to cookies but only readable by this site (no third-party access).
Default state: nothing tracking-related runs until you accept
We implement Google Consent Mode v2. Until you click Accept on the cookie banner, analytics and advertising buckets — analytics_storage, ad_storage, ad_user_data, and ad_personalization — stay denied. Google Analytics and AdSense cookies are not set until you accept.
Cookies and storage we use
The table below lists every cookie or storage key our site uses, who sets it, what it does, and how long it lasts.
| Cookie / key | Set by | Type | Purpose | Duration |
|---|---|---|---|---|
| cc-consent | First-party (this site, localStorage) | Strictly necessary | Stores your consent decision ("accepted" or "declined") so we don't ask again on every visit. | Until you clear local storage |
| bc-lang | First-party (this site, localStorage) | Strictly necessary | Stores your language preference (en / zh / ja / ru) so the site loads in the same language next time. | Until you clear local storage |
| _ga, _ga_* | Third-party (Google Analytics 4) | Analytics — only after consent | Distinguishes unique visitors and tracks page views, sessions, and basic interactions. We set anonymize_ip. | Up to 13 months |
| _gid | Third-party (Google Analytics) | Analytics — only after consent | Identifies a returning user across pages within a single day. | 24 hours |
| _gads, _gpi, __gads | Third-party (Google AdSense) | Advertising — only after consent | Helps Google show and measure ads on pages that already have enough original writing. Not used on the paid checkout page. | Up to 13 months |
| IDE | Third-party (doubleclick.net) | Advertising — only after consent | Used by Google to show personalized or non-personalized ads and measure ad performance, after you accept. | Up to 13 months |
Manage your consent
You can change your decision at any time. Click the button below to reopen the cookie banner and choose again. Declining sets analytics and advertising buckets back to denied and prevents non-essential cookies on future visits.

Changes to this policy
We may update this Cookie Policy when we change which services we use or how cookies are configured. The "Last updated" date at the top will reflect any change. Continued use of the site after a change means you accept the updated policy.
