Start with the boundary.
StackCache cannot inspect or recover browser-local data. The steps below keep diagnosis useful without asking you to disclose a payload or secret.
What can I do if my vault passphrase is lost?
There is no reset or recovery service. If you have a valid encrypted backup and its separate passphrase, clear the inaccessible local vault, create a new vault passphrase, then import the backup. Without both backup file and backup passphrase, encrypted records cannot be recovered.
How do I recover after browser data was cleared or evicted?
Use the encrypted import on Encrypted Secrets. Persistent-storage permission reduces automatic eviction risk but does not prevent manual clearing, profile removal, device loss, or browser damage. Keep downloaded backups outside the browser profile.
How do I clear all StackCache browser data?
Unlock Encrypted Secrets and use “Clear all StackCache browser data” at the bottom of the page. It locks first and removes the vault and temporary share databases, known preferences, reminder timestamps, and StackCache offline caches. It cannot delete downloaded backup files or authenticator credentials managed by your browser or device.
What should I do when camera or clipboard access fails?
Open StackCache over HTTPS or localhost, review the site permission in browser settings, then retry from the explicit action. QR scanning retains image-file input; output text can be selected manually when clipboard access is denied.
Why did a CORS, mixed-content, or MQTT request fail?
Browsers enforce the destination server’s CORS policy and block insecure requests from secure pages. HTTP destinations must use HTTPS and permit the StackCache origin, method, and requested headers. A browser-level failure may not reveal whether CORS, DNS, TLS, an extension, or connectivity caused it. Do not disable browser security; use the destination’s documented browser API or a trusted native client. MQTT supports secure WebSocket endpoints only; raw TCP and ordinary mqtt:// require a native client.
Why does a tool say planned or mobile-only?
Planned tools are not enabled in this implementation. LAN scanning, Wi-Fi identity, raw TCP scanning, and operating-system integrations require the native application because ordinary browsers do not expose equivalent capabilities.
How can I ask for more help safely?
Email support@stackcache.app with the route or tool name, StackCache version, browser version, capability status, and sanitized reproduction steps. Never send passwords, tokens, TOTP seeds, env files, encrypted backups, authorization headers, or production payloads.
