Cookies and browser storage

Storage used to provide the service

Cookies are small records sent with browser requests. Local storage stays in your browser until removed; session storage is normally limited to the current tab. We use the following storage for sign-in and the study functions you request.

• Supabase sign-in cookies (sb-…): keep the account session and support secure sign-in. The current sign-in library sets these cookies for up to 400 days and may refresh them when your session is renewed; a server session can expire sooner. Names and chunks depend on the sign-in flow. Signing out clears the authentication session.
• as_signed_in: a session cookie that chooses the correct public-header link. It does not authorise access.
• airspace_visitor: a signed sample or local test-session cookie lasting up to seven days. Paid access still requires a verified account and entitlement.
• airspace:session-length: local storage that remembers the practice length you choose until you clear it or change it.
• airspace:pending:…: tab session storage that can hold an unconfirmed study action so you can retry it after a failed save. It is removed after confirmation, discarding the action or signing out.

Blocking necessary cookies can prevent sign-in or study-session recovery. Clearing local storage removes saved device preferences; it does not delete your account or cancel a subscription.

Analytics and external services

Vercel Web Analytics measures visits and selected public sample interactions without analytics cookies. It is still data processing: see our privacy notice for the information used, purpose and your rights. We do not use advertising cookies or cross-site advertising pixels in the site code.

If you use Google sign-in or follow a link to Stripe or Link checkout, those services may use their own cookies and storage under their own notices. Their pages and browser settings explain the available controls.

Your choices

You can inspect, block and delete this site’s cookies and storage through your browser’s privacy settings. You can also contact support@airspaceschool.com about privacy or object to processing based on legitimate interests. Any future non-essential storage that requires consent must remain off until you agree; acceptance of the terms is not cookie consent.
