Cookie Policy
How Nisium uses cookies, browser storage, and similar technologies on nisium.com.
Last updated: June 2, 2026 · Version 1.0
This Cookie Policy explains how Expert Allies LTD ("we", "us") uses cookies and similar technologies when you visit nisium.com and use Nisium (the Service). It should be read with our Privacy Policy.
Capitalized terms not defined here have the meaning in the Privacy Policy.
1. What are cookies and similar technologies?
Cookies are small text files stored on your device. Local storage and session storage are browser mechanisms that store data on your device without expiring when the browser closes (local) or that clear when the tab closes (session). We refer to all of these as technologies below.
2. How we use technologies
We use technologies to:
- Keep you signed in and secure your session
- Remember preferences (e.g. language)
- Store your cookie consent choice
- Support vendor portal flows and demo authentication paths in development
We do not currently use marketing or analytics cookies (such as Google Analytics) on the Site. If we add them later, we will update this policy and request consent where required.
3. Types of technologies
3.1 Strictly necessary
Required for authentication, security, and core functionality. These cannot be switched off in our banner without losing access to the Service.
| Name / key | Type | Purpose | Duration |
|---|---|---|---|
| ------------ | ------ | --------- | ---------- |
| Cognito / Hosted UI cookies | Cookie | Login and session with Amazon Cognito | Session / per Cognito policy |
| `cr_cognito_access_token` | sessionStorage | Cognito access token during login flows | Browser session |
| `cr_pending_login` | sessionStorage | Continue login after MFA step | Browser session |
| `cr_demo_token`, `cr_demo_user`, `cr_demo_active_tenant` | localStorage | Demo authentication (non-production / dev paths only) | Until cleared |
3.2 Functional
Improve usability; not strictly required for every page but expected for normal use.
| Name / key | Type | Purpose | Duration |
|---|---|---|---|
| ------------ | ------ | --------- | ---------- |
| `cr_demo_lang` | localStorage | UI language (English / Bulgarian) | Until cleared |
| `cr_passkey_onboarding_done_*` | localStorage | Remember passkey onboarding completion | Persistent |
| Vendor portal UI keys | localStorage | Remember vendor questionnaire UI state | Until cleared |
3.3 Consent storage
| Name / key | Type | Purpose | Duration |
|---|---|---|---|
| ------------ | ------ | --------- | ---------- |
| `nisium_cookie_consent` | localStorage | Record accept/reject for non-essential cookies (future analytics) | Until cleared |
3.4 Analytics (not used today)
We do not set analytics cookies in the current release. The consent banner allows you to accept or reject non-essential cookies so that future analytics, if introduced, respect your choice.
4. Legal basis (EEA/UK)
- Strictly necessary technologies: legitimate interest / necessity to perform the contract
- Functional technologies: legitimate interest or consent where required by local law
- Non-essential / analytics (when added): consent via our banner
5. Managing your choices
- Use the cookie banner on first visit: Accept all or Reject non-essential
- Clear site data in your browser settings to reset stored keys
- Block cookies in the browser — some features (especially sign-in) may stop working
For Cognito cookies, manage preferences in your browser or sign out of the Service.
6. Updates
We may update this Cookie Policy when technologies change. The Last updated date at the top of the published page will change accordingly.
