Cookie Policy
Effective and last updated: 7 September 2026
This policy explains how Studyssey uses cookies and similar browser storage. It should be read with our Privacy Policy.
1. Cookies and browser storage
Cookies are small text files stored by a website. Local storage and session storage are similar browser technologies used to remember information on your device. This policy covers all of them.
2. Necessary storage
Necessary storage supports authentication, security, a form or report you request, and your privacy choice. The core platform cannot provide those requested functions without it, so it is not switched off by the optional-services control.
| Name or pattern | Technology | Purpose | Typical duration |
|---|---|---|---|
| Supabase authentication cookies (including sb-…-auth-token variants) | Cookie | Keeps you securely signed in and refreshes the session you requested. | Session duration; refreshed during active use |
| studyssey_cookie_consent_v1 | Local storage | Remembers whether you accepted or rejected optional services. | 180 days |
| studyssey_session_started_at | Local storage | Enforces the platform session-age security limit. | Up to 24 hours |
| studyssey_readiness_* | Local storage | Connects a requested free readiness report to your browser and prefills the signup handoff. | Until you clear site data |
| pending_verification_email and pending_auth_redirect | Session storage | Completes the email-verification journey in the current tab. | Until the workflow finishes or the tab closes |
| ep_assistant_chat_v2:* | Local storage | Keeps a signed-in user’s requested assistant conversation available on that device. | Until New chat is selected or site data is cleared |
Authentication cookie names may be split into numbered parts by the provider when a session value is large.
3. Optional services
These services load only after you select “Allow optional services”:
- Google preferred-source widget: loads Google code used to display its publisher control. Google may receive technical connection data and apply its own storage rules.
- Sentry browser monitoring: helps us diagnose browser errors and performance problems. We disable default personal-information collection and do not enable session replay, but an error report can still contain technical request, device, page, and diagnostic data.
Rejecting optional services leaves sign-in, applications, payments, and all core platform features available.
4. Change or withdraw your choice
Use the Cookie settings button above or in the site footer at any time. Accepting and rejecting each take one action. When you change an existing choice, the page reloads so previously enabled third-party browser code is fully unloaded.
You can also delete site data through your browser. Doing so may sign you out and remove saved report or assistant state.
