Cookie and local-storage overview for DueKit

DueKit uses local browser storage and a small session model so people can continue local drafts, sign in where verification is active, and keep basic product state stable. This page explains the current behavior without implying a larger tracking stack.

What this page covers

Describe only the currently shipped cookie and local-state behavior.
This page is scoped to the live root product: guest-first local drafts, magic-link sign-in where verification is active, and the safeguards that keep those flows working.
What is currently used

What is currently used

  • Essential session cookies may keep sign-in state and verification continuity available on the current controlled recovery surfaces.
  • Local browser storage may keep guest drafts, return-state signals, and lightweight continuation helpers available before account value is required.
  • Operational safeguards may use short-lived technical state to reduce abuse, protect routes, and keep the product available.
Why it is used

Why it is used

This page is scoped to the live root product: guest-first local drafts, magic-link sign-in where verification is active, and the safeguards that keep those flows working.

  • Keep the workflow recoverable so local quote and invoice drafts, plus controlled recovery prompts, do not force people to start over.
  • Protect sign-in, rate-limited routes, and other operational boundaries needed to run the current release safely.
  • Preserve low-friction product behavior rather than build a broad behavioral-advertising profile.
Controls and limits

Controls and limits

  • Browser controls may clear local drafts, sign-in state, or continuity helpers that the current workflow relies on.
  • Some essential cookies are required for sign-in continuity, workspace recovery, or service protection and should not be described as optional preference tracking.
  • If cookie or local-state behavior changes materially, the new behavior should appear here before the live product depends on it.
Important limits

Important limits

This page describes the current product state in plain language rather than jurisdiction-specific compliance obligations.

  • It does not promise an advertising, affiliate-tracking, or personalization system that the current root surface does not ship.
  • Questions about actual browser-state behavior should be routed through support so the shipped behavior can be confirmed against the live product.
