02 Frequently asked
What the access layer does—and does not do.
What does Zulde store?
An encrypted recipient email, a keyed hash of the six-character code, status timestamps, and minimal non-sensitive access events.
Does Zulde store documents?
No. Zulde does not upload, host, index, or retain documents.
Does Zulde store the destination?
No. A fresh one-time destination is requested from the shared service only after a successful lookup.
How long does a code work?
The code remains reusable until the issuing integration revokes it. Each generated destination is short-lived.
Why am I temporarily blocked?
Repeated attempts trigger short lockouts designed to slow automated code guessing.
Can I recover a lost code?
Contact the organization that issued the code. Zulde cannot display or recover full codes from its database.
