Privacy Policy

Overview

CacheStack Ltd ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your personal information when you visit our website or subscribe to our newsletter.

Information We Collect

We may collect the following information:

• Email address: when you subscribe to our newsletter
• Name: optionally provided when subscribing
• Usage data: pages visited, time spent, referring site (via Vercel Analytics)
• Technical data: IP address, browser type, device information

How We Use Your Information

We use your personal data to:

• Send you our newsletter and insights you have requested
• Improve our website and services
• Respond to your inquiries
• Comply with legal obligations

Newsletter Subscriptions

When you subscribe to our newsletter, we store your email address and optional name. You can unsubscribe at any time by clicking the "Unsubscribe" link at the bottom of any email, or by visiting cachestack.co.uk/blog/unsubscribed with your unsubscribe token.

We use Resend (a US-based email service) to deliver our emails. Your email address is stored securely in our database hosted on Supabase (EU region).

Cookies and Analytics

We keep cookies to a minimum. This site sets no advertising cookies, no tracking pixels, and nothing that follows you to other websites.

• Analytics: we use Vercel Analytics to understand how visitors move through the site. It is cookie-free and does not identify you or build a profile of you, which is why this site does not ask you to accept cookies before you can read it.
• Strictly necessary cookies: if you sign in to a client portal or admin area at this domain, we set a session cookie so you stay signed in, and a security token to protect the forms you submit. These are essential to a service you have asked for and cannot be switched off while you are signed in. Signing out clears them.

You can block or delete cookies in your browser settings. Doing so will not affect browsing the public site; it will stop you signing in to the portal.

Data Retention

We retain your personal data only as long as necessary:

• Newsletter subscribers: until you unsubscribe or request deletion
• Client data: as required for contractual and legal obligations
• Analytics data: aggregated and anonymised after 12 months

Your Rights

Under UK GDPR, you have the right to:

• Access your personal data
• Correct inaccurate data
• Request deletion of your data
• Object to processing
• Request data portability
• Withdraw consent at any time

To exercise these rights, contact us at team@cachestack.co.uk.

Data Security

We implement appropriate technical and organisational measures to protect your personal data, including encryption in transit and at rest, access controls, and regular security reviews.

Third-Party Services

We use the following third-party services:

• Vercel: website hosting and analytics (US)
• Supabase: database hosting (EU)
• Resend: email delivery (US)
• LinkedIn: social media integration (optional)

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "Last updated" date.
