1. Your choice
Essential storage supports sign-in, security and the features you request. Optional browser error diagnostics are off by default. We do not require you to allow them to use Cuebooks, and we do not use advertising cookies in this version.
Optional browser diagnostics: off. Essential sign-in and security storage remains available.
Optional browser diagnostics are not configured for this environment, so there is nothing optional to accept.
2. Essential cookies
Names beginning with sb- belong to our Supabase sign-in service. Some internal names still contain the previous project identifier; that does not mean a different company operates Cuebooks.
| Cookie | Purpose | Lifetime |
|---|---|---|
sb-…-auth-token | Keep your sign-in session working. Large values may be split into numbered cookies. | Up to 400 days under the installed client defaults, renewed or cleared by authentication. This is not the lifetime of an access token or a guarantee you stay signed in. |
sb-…-auth-token-code-verifier | Protect supported sign-in/confirmation exchanges. | Temporary verification state; removed when the exchange completes. Provider/client expiry is a fallback. |
accountai_business_id | Remember which business you selected. | 30 days, or cleared when changed/signed out. |
accountai_email_confirmation_token | Complete email confirmation safely. | 15 minutes. |
accountai_recovery_token | Complete password recovery safely. | 10 minutes. |
3. Other browser storage
accountai.registration.pending-emailuses session storage to show the address awaiting confirmation and support resending. It is cleared with the browser session or when the relevant flow clears it.cuebooks.diagnostics-consent.v1remembers a diagnostics choice for up to 180 days. It contains the choice and its expiry, not your accounting records. After expiry it is ignored until you choose again.- The
cuebooks-shell-v2service-worker cache stores the offline page, app manifest and icon. It does not cache authenticated pages, uploaded documents, API responses or financial records. It remains until replaced or cleared in your browser.
4. Optional diagnostics and server logs
If Sentry browser diagnostics are configured and you allow them, the browser can send filtered error reports to help investigate faults. These can include technical event information and network metadata. We do not enable browser performance tracing or session replay through this choice.
Use “Use essential only” above to stop optional browser reports. This does not erase reports already sent or turn off necessary hosting/security logs and separately configured server diagnostics. Those are explained in our privacy notice.
5. Your browser controls
You can also block or clear cookies and site storage in your browser. Clearing essential cookies may sign you out, forget the selected business or interrupt an email-confirmation/recovery link. Clearing site storage removes your diagnostics preference, returning it to off.
Preferences apply to this browser and site address. Another device or a different domain has its own storage and starts with optional diagnostics off. Questions? Email support@cuebooks.co.uk.
