Your device
- An encrypted vault: your recovery phrase's derived keys, your wallet map, your activity log, your settings. Locked with a password you choose; unlocked only in memory.
- A cache of public pool notes so a refresh does not start from zero. Public data, same for everyone.
- Your RPC URL and privacy profile.
- An invite code you opened a link with, for seven days, until you apply or discard it.
- The backup file you export, encrypted with a password of your choosing.
Stored by WiSP: never. Two items on this list are used in requests: the RPC URL you set, and an invite code when you apply it. Deleting your browser data or the backup removes all of it; the phrase brings back everything derived from it (one-time Receive addresses, when that feature is on, are recorded only in your backup).
