Cookie Settings
Manage how Teacher uses cookies on your device.
Effective Date: 21 May 2026
Cookies are small text files stored on your device. We use them sparingly — only to make Teacher work and (with your permission) to understand how it's used. You can change your preferences at any time using the button below.
Necessary Storage Always on
Essential for the Service to function. Without these you couldn't stay logged in or remember your consent choice.
| Name | Type / Domain | Purpose | Lifetime |
|---|---|---|---|
| teacher_cookie_consent | localStorage · this site | Remembers your cookie consent choice and preferences. | Persistent until cleared |
| KEYCLOAK_* | Cookie · auth.gridex.ai | Authentication session on the identity provider. Set only after you sign in. | Session |
| __stripe_mid / __stripe_sid | Cookie · checkout.stripe.com | Stripe fraud detection. Set only while you are on the Stripe-hosted checkout page. | 1 year / 30 minutes |
Functional Storage Optional
Small preferences that make the Service nicer to use. Disabling them resets your chosen language and personalisation on every visit.
| Name | Type / Domain | Purpose | Lifetime |
|---|---|---|---|
| teacher-locale | localStorage · this site | Stores your chosen interface language. | Persistent until cleared |
| teacher.userSettings.v1 | localStorage · this site | Stores in-app preferences (native / target language, voice on/off). | Persistent until cleared |
Analytics Optional
Helps us understand how the Service is used so we can improve it. We use Microsoft Application Insights. No data is sold or shared with advertisers.
| Name | Type / Domain | Purpose | Lifetime |
|---|---|---|---|
| ai_user | Cookie · this site (first-party) | Application Insights unique-user counter. | 12 months |
| ai_session | Cookie · this site (first-party) | Application Insights session correlation. | 30 minutes |
