Route ZERO legal
RouteZero Cookie Policy
1. About this Policy
This Policy explains how Dynamon Ltd uses cookies and similar storage when you use RouteZero, routezero.app, dynamon.co.uk, or related domains.
'Cookies and similar technologies' includes HTTP cookies, localStorage, sessionStorage, and equivalent browser storage.
In short: we use strictly-necessary cookies to keep you signed in and protect against cross-site request forgery, and localStorage to preserve your in-progress route work between sessions. We don't use analytics, advertising, or tracking cookies. Third-party sign-in and mapping providers may set cookies on their own domains (Section 4).
Under PECR, strictly-necessary storage doesn't require consent. We don't currently need a cookie banner; if we add non-essential storage, we'll update this Policy and implement consent first.
2. Cookies we set
| Name | Purpose | Expiry |
|---|---|---|
| next-auth.session-token | Keeps you logged in (NextAuth JWT) | 6 hours |
| next-auth.csrf-token | CSRF protection for sign-in/out | Session |
| next-auth.callback-url | Return URL after sign-in | Session |
| next-auth.state, next-auth.pkce.code_verifier | OAuth sign-in flow (Cognito) | Transient |
__Secure-/__Host- prefixed names are used in production over HTTPS; unprefixed names are used in local development.
3. Browser storage (localStorage)
RouteZero stores the following on your device only — not transmitted to third parties:
| Category | Examples | Purpose |
|---|---|---|
| Route work-in-progress | Route configuration, stops, last analysis results | Survive a page reload without re-running analyses |
| Vehicle and UI preferences | Last-selected mode, tractor/trailer/rigid, efficiency settings | Remember your choices |
| Cached fleet lists | Tractor and trailer lists | Reduce repeated server fetches |
Entries persist until you clear them or RouteZero resets them. They hold your own operational state — not third-party tracking data.
4. Third-party cookies
| Service | When | Notes |
|---|---|---|
| AWS Cognito | Sign-in / sign-out | Session cookies on zero-auth.dynamon.co.uk |
| Google Maps | Maps, geocoding, autocomplete | See Google's cookie policy |
Blocking these may prevent sign-in or degrade mapping features.
5. Your choices
You can block or delete cookies and clear site storage in your browser. Doing so for strictly-necessary items will prevent normal use of RouteZero. Private/incognito mode clears storage when you close the window.
6. Changes and contact
We'll update this page when our use of cookies changes. Questions: support@dynamon.co.uk. ICO complaints: see our Privacy Notice.
