Cookie Policy
Last updated: 7 March 2026
1. About this policy
This Cookie Policy explains how Catalyst Neuromorphic Ltd (Company No. 17054540) uses cookies and similar technologies on catalyst-neuromorphic.com and its subdomains. This policy should be read alongside our Privacy Policy.
We aim to be minimal and transparent. We do not use advertising cookies, social media trackers, or invasive analytics. This policy complies with the UK Privacy and Electronic Communications Regulations 2003 (PECR) and UK GDPR.
2. What are cookies?
Cookies are small text files stored on your device by your web browser when you visit a website. Similar technologies include localStorage and sessionStorage in the browser. These can store preferences, session information, and other data needed for the site to function.
3. What we use
We use a very limited set of cookies and browser storage. Here is a complete list:
Strictly essential (no consent required under PECR)
These are necessary for the Service to function. They cannot be disabled without breaking core functionality.
| Name | Type | Purpose | Duration |
|---|---|---|---|
session_token | localStorage | Authenticates your logged-in session with the Catalyst Cloud console and API. Stored locally in your browser, sent as a Bearer token in API requests. | Until logout or manual deletion |
__cf_bm | Cookie (Cloudflare) | Cloudflare bot management cookie. Distinguishes human visitors from automated bots to protect against DDoS attacks and abuse. | 30 minutes |
_cfuvid | Cookie (Cloudflare) | Cloudflare rate-limiting cookie. Used to apply per-visitor rate limits for security. | Session |
Payment processing (set by Stripe during checkout)
When you interact with a payment form or checkout page, Stripe may set cookies to process your payment securely and prevent fraud. These cookies are set by Stripe's domain, not ours.
| Name | Type | Purpose | Duration |
|---|---|---|---|
__stripe_mid | Cookie (Stripe) | Stripe fraud detection and payment session identifier. | 1 year |
__stripe_sid | Cookie (Stripe) | Stripe session identifier for active payment flows. | 30 minutes |
Analytics cookies
We do not use Google Analytics, Facebook Pixel, or any third-party analytics or tracking cookies. We do not serve advertising of any kind.
4. What we do not use
- No advertising or targeting cookies
- No social media tracking pixels or widgets
- No third-party analytics (Google Analytics, Hotjar, Mixpanel, etc.)
- No cross-site tracking
- No fingerprinting technologies
5. How to control cookies
Because we only use strictly essential cookies (required for the Service to function) and third-party payment cookies (set by Stripe), we do not display a cookie consent banner. Under PECR, consent is not required for cookies that are strictly necessary for the provision of a service explicitly requested by the user.
You can still control cookies through your browser settings:
- Chrome: Settings → Privacy and Security → Cookies and other site data
- Firefox: Settings → Privacy & Security → Cookies and Site Data
- Safari: Preferences → Privacy → Manage Website Data
- Edge: Settings → Cookies and site permissions → Cookies and site data
To clear localStorage (which contains your session token), you can use your browser's developer tools (usually F12 → Application → Local Storage) or clear all site data for catalyst-neuromorphic.com. Note that clearing your session token will log you out.
Blocking Cloudflare cookies may prevent access to the site, as they are part of Cloudflare's security infrastructure. Blocking Stripe cookies may prevent payment processing.
6. PECR compliance
Under the Privacy and Electronic Communications Regulations 2003 (PECR), we are not required to obtain consent for cookies that are strictly necessary for the provision of a service you have requested. All cookies we set fall into this category. If we ever introduce non-essential cookies (e.g., analytics), we will implement a consent mechanism before doing so.
7. Changes to this policy
If we add new cookies or change how we use browser storage, we will update this page and revise the "Last updated" date. If we introduce non-essential cookies, we will notify you and obtain consent before setting them.
