1. Cookies myoh.ai needs
These cookies sign you in, keep you signed in and remember your language.
| Cookie | Purpose | Lasts |
|---|---|---|
| myoh_session | Keeps you signed in | 30 days |
| oauth_state | Protects Google sign-in | 10 minutes |
| NEXT_LOCALE | Remembers your language | Until you close the browser |
We also keep your progress while signed out and a few preferences, such as your theme, in your browser's local storage. That data stays on your device.
2. Analytics
PostHog measures how myoh.ai is used, such as which lessons people open and where they stop, so we can improve them. It loads for every visitor and keeps an ID for your browser in a cookie and in local storage.
Google Analytics measures visits too, but only if you accept it in the cookie banner. Until then it does not load and sets no cookies.
| Cookie | Purpose | Lasts |
|---|---|---|
| ph_…_posthog | PostHog: recognises your browser | 1 year |
| _ga | Google Analytics: tells visitors apart, only if you accept | 2 years |
| _ga_… | Google Analytics: keeps the visit's state, only if you accept | 2 years |
Grafana Faro records errors and loading times so we can fix problems. It keeps an ID for your visit in your browser's session storage, which is cleared when you close the tab.
These analytics and monitoring tools help us understand and improve myoh.ai.
3. Advertising measurement
With your permission, the OpenAI Ads Pixel measures page visits and new myoh Plus subscriptions to help us understand which ChatGPT ads lead to subscriptions. It shares these events, your selected plan, advertising identifiers and browser information with OpenAI. It loads only after you enable advertising measurement in the cookie banner.
| Cookie | Purpose | Lasts |
|---|---|---|
| __oppref | Connects a visit to a ChatGPT ad click | 30 days |
| __obref | Recognises your browser for advertising measurement | 1 year |
If advanced matching is enabled in our OpenAI settings, the pixel may also hash contact details entered in website forms to help match conversions. After advertising consent, we store a temporary checkout reference, your account ID and plan in local storage to recover missed events and avoid counting the same checkout more than once. It is eligible for retries for 24 hours and removed on the next visit after expiry, when you sign out, or when you withdraw advertising consent. Your account ID is not included in OpenAI events. Before consent, an ad reference already present in the address bar is held only in page memory during navigation and is discarded if you decline.
4. Your choices
You can choose Google Analytics and OpenAI advertising measurement separately in the cookie banner and change either choice any time with Cookie settings at the bottom of every page. Declining a purpose stops that tool and removes its cookies. Earlier Google Analytics acceptance does not enable advertising measurement; earlier refusals are preserved.
You can delete cookies and site data in your browser settings. You will be signed out, and progress made while signed out will be lost. See our Privacy Policy for more.
