TalkasuCookie policy
How Talkasu uses cookies and similar technologies on the website.
What this covers
Cookies and similar storage (localStorage, sessionStorage, IndexedDB) can remember a signed-in session, keep a feature working, measure how the site is used, or measure advertising. Optional analytics and the OpenAI Ads Measurement Pixel run only if you accept.
You can change optional analytics and advertising measurement at any time. Rejecting them does not block browsing or signing in.
Necessary
These are required to provide the service you request (sign-in, security, and remembering this cookie choice). They are always on.
| Name | Provider | Duration | Purpose |
|---|---|---|---|
| Firebase Auth (IndexedDB, typically firebaseLocalStorageDb) | Talkasu / Google Firebase | Until you sign out | Keep you signed in on this browser |
| talkasu:cookie-consent (localStorage) | Talkasu | Until you clear site data or we change cookie categories | Remember your cookie choice |
| talkasu:just-completed:* / talkasu:training-finished:* (sessionStorage) | Talkasu | Browser session | Show training-complete celebration after a lesson |
| Google Sign-In cookies on accounts.google.com | Set by Google | Only after you choose Sign in with Google |
Analytics (optional)
Used only if you accept. Measurement ID G-ZTVG409V4N. Legal basis: consent. Google's privacy policy: policies.google.com/privacy.
| Name | Provider | Duration | Purpose |
|---|---|---|---|
| _ga | Google Analytics 4 | Up to 2 years | Distinguish unique visitors |
| _ga_ZTVG409V4N | Google Analytics 4 | Up to 2 years | Persist session state |
| _gid (sometimes) | Google Analytics 4 | 24 hours | Distinguish unique visitors |
| Firebase Installations / Analytics (IndexedDB) | Google Firebase | Deleted when you reject or withdraw analytics; otherwise until you clear site data | Analytics install and client identifiers |
Advertising measurement (optional)
Used only if you accept. Legal basis: consent. The OpenAI Ads Measurement Pixel (script from bzrcdn.openai.com, events to bzr.openai.com) measures website activity that can be attributed to ads in ChatGPT. It may store a privacy-preserving ad click identifier and a random browser reference. OpenAI's privacy policy: openai.com/policies/privacy-policy.
| Name | Provider | Duration | Purpose |
|---|---|---|---|
| __oppref | OpenAI Ads Measurement Pixel | 30 days | Store a ChatGPT ad click attribution identifier |
| __obref | OpenAI Ads Measurement Pixel | 365 days | Random browser reference for measurement |
Rejecting or withdrawing consent calls the Pixel's consent-off command, which removes these cookies and stops measurement events.
Not used
Talkasu does not set social-media or remarketing pixels (for example Meta, TikTok, or X), and does not sell personal information. If your browser sends a Global Privacy Control signal, we treat analytics and advertising measurement as off.
