The shortest route to the next honest action.

KYSTA starts with a device-bound account. Link and verify an email address from Profile so the account can be recovered on another device. Never share a validation code.

Use the install action shown by your browser or KYSTA. When an update is ready, use the in-app update control, then close every KYSTA window and reopen the installed app. If the old version remains, open KYSTA in the browser once while online before trying again.

KYSTA can keep an effective-user-scoped working copy and queue supported evidence while offline. Settings shows queued items, last sync and storage. Reconnect and use Sync now before clearing site data or changing devices; the backend remains authoritative.

Notifications are optional and require your browser permission. Enable or disable reminders in Profile and use Settings diagnostics if delivery stops. KYSTA does not use evidence reminders as marketing consent.

Use Today for explicit check-ins and Log for measured activities. If an entry is inaccurate, use its edit action. A missing entry remains unknown until you record or explicitly resolve it.

Profile contains the current plan, checkout, cancellation and invoices. Invoice PDFs download through the authenticated application. Contact support@kysta.app if the provider has charged you but access has not updated.

Settings provides JSON and CSV export, behavioural-data clearing and account deletion. Read the warning carefully: deletion is deliberately explicit.

Installed-app updates vary by browser and device, and notification delivery can be delayed by operating-system settings. Email support@kysta.app with the affected page, approximate time, device/browser and a non-sensitive description. Do not send passwords, validation codes, payment credentials or private evidence.
