Cookie Policy
Last updated: April 2026
This policy explains what cookies QuantDine uses, why we use them, and what your rights are. We've kept this as simple and honest as possible.
1. What are cookies?
Cookies are small text files stored on your device when you visit a website. They help websites remember information about your visit — like whether you're logged in.
2. What cookies we use
| Cookie name | Purpose | Type | Duration |
|---|---|---|---|
| next-auth.session-token | Keeps you logged in to your QuantDine account | Strictly necessary | Session |
| next-auth.csrf-token | Security token to prevent cross-site request forgery | Strictly necessary | Session |
| next-auth.callback-url | Remembers where to redirect you after login | Strictly necessary | Session |
| __stripe_mid | Stripe payment fraud prevention | Third party (Stripe) | 1 year |
| __stripe_sid | Stripe payment session | Third party (Stripe) | 30 minutes |
3. What we don't use
We currently do not use:
- Analytics cookies (no Google Analytics, no Vercel Analytics)
- Marketing or advertising cookies
- Social media tracking pixels
- Any third-party tracking beyond Stripe on checkout pages
4. Strictly necessary cookies
The session and security cookies listed above are strictly necessary for QuantDine to function. You cannot opt out of these while using the platform — without them, you cannot stay logged in.
5. Third party cookies (Stripe)
When you visit our pricing page or complete a payment, Stripe (our payment processor) may set cookies on your device for fraud prevention purposes. These cookies are governed by Stripe's own privacy policy, available at stripe.com/privacy.
6. Your rights
Under UK GDPR and the Privacy and Electronic Communications Regulations (PECR), you have the right to:
- Know what cookies we use and why (this policy fulfils that)
- Withdraw consent for non-essential cookies at any time
Since we only use strictly necessary and Stripe payment cookies, there are currently no optional cookies to opt out of. If we introduce analytics or marketing cookies in the future, we will update this policy and ask for your consent before setting them.
7. Changes to this policy
We may update this policy as our use of cookies changes. The date at the top of this page will always reflect when it was last updated. We will notify logged-in users of any material changes.
