MyJSON
Settings

Session-only mode

Skip localStorage for this document — refresh wipes it.

Status bar toggle near the `local-only` badge.

What it does

Disables the localStorage persistence layer for the editor content. The document is held in memory only — refresh, close tab, or browser crash clears it.

When to use

Anytime you paste something sensitive: JWTs, customer PII, internal IDs, secrets. Session-only ensures it disappears the moment you're done.

What stays saved

Theme, indent, view choice, schema text, query text — these all still persist. Only the main document and diff input are dropped.

Examples

Inspect a production payload safely

An on-call dev shared a payload that contains customer email addresses.

  1. Open MyJSON.
  2. Click `persisted` in the status bar — it flips to `session-only`.
  3. Paste, inspect.
  4. Refresh the tab. Editor is empty.
