Privacy Policy
1. Introduction
ReviewLinker™ (“we”, “us”, or “our”) is operated by Eight Two Studio Ltd. This Privacy Policy explains how we collect, use, disclose, and protect information when you use the ReviewLinker website located at www.reviewlinker.io (the “Service”).
By using the Service, you agree to the collection and use of information as described in this policy. If you do not agree, please do not use the Service.
2. Information We Collect
We collect the following types of information:
- Account information — when you create an account, we collect your email address and, optionally, your first and last name.
- Book and link data — the book titles, ASINs, custom URL slugs, and settings you create within the Service.
- Subscription and billing data — your subscription plan and Stripe customer ID. We do not store your full payment card details — these are handled directly by Stripe.
- Link click data — when a reader clicks a ReviewLinker redirect link, we log the destination Amazon marketplace, approximate country, and traffic source (link or QR scan). No personal data about the reader is stored.
- Usage data — through Google Analytics (with your consent), we collect anonymised data about how visitors interact with the site (e.g. pages visited, time on site, device type, country). This data does not identify you personally.
- Contact form submissions — if you contact us via our contact form, we store your name, email address, and message.
- Technical data — server logs and error reports collected automatically by our hosting and error monitoring providers.
3. How We Use Your Information
We use the information we collect to:
- Create and manage your account and provide the Service.
- Process payments and manage your subscription.
- Send transactional emails (e.g. account confirmation, billing receipts).
- Send product updates and announcements (email marketing — you can unsubscribe at any time).
- Display click analytics within your dashboard.
- Understand how the Service is used so we can improve it.
- Diagnose technical issues and maintain service reliability.
- Respond to support requests.
- Comply with legal obligations.
We will never use your information for any purpose not listed above.
4. Legal Basis for Processing (UK GDPR)
Where UK GDPR applies, we process your personal data on the following legal bases:
- Contract performance (Article 6(1)(b)) — we process your account data, book data, and billing information to provide the Service you have signed up for.
- Consent (Article 6(1)(a)) — we process your email address for marketing communications and use Google Analytics cookies only with your consent. You may withdraw consent at any time by unsubscribing or adjusting your cookie preferences.
- Legitimate interests (Article 6(1)(f)) — we process anonymised analytics data, redirect click logs, and error monitoring data on the basis of our legitimate interest in improving the Service and maintaining its security. This processing does not override your rights and freedoms.
- Legal obligation (Article 6(1)(c)) — where required, we process data to comply with applicable laws.
5. Email Communications
When you create an account, we may send you product updates and announcements about ReviewLinker. You can unsubscribe at any time using the link at the bottom of any marketing email we send.
We will always send transactional emails required to deliver the Service (e.g. email verification, billing confirmations). These cannot be opted out of while you have an active account.
We use Kit (formerly ConvertKit) to manage email subscribers and Resend to send transactional emails. Your email address is processed by these providers in accordance with their own privacy policies.
6. Cookies and Analytics
We use Google Analytics to understand how visitors use the Service. Google Analytics uses cookies to collect information about site usage. This data is anonymised and aggregated — we do not use it to identify individual users.
We only load Google Analytics after you have given your consent via our cookie banner. You can change your preferences at any time using the cookie preferences link in the footer.
For full details of the cookies we use, see our Cookie Policy.
7. Third-Party Services
We use the following third-party services that may process your data:
- Stripe — payment processing and subscription management. Card details are handled directly by Stripe and are never stored on our servers.
- Supabase — database and authentication infrastructure. Your account and book data is stored in Supabase’s EU-hosted infrastructure.
- Kit (ConvertKit) — email marketing. Your email address and optional first name are stored and processed by Kit, Inc.
- Resend — transactional email delivery (e.g. account verification, billing receipts).

- Vercel — hosting provider. Server logs may be retained by Vercel for operational purposes.
- Cloudflare R2 — object storage used to hold automated daily database backups. Backups contain account and book data and are retained for 30 days before deletion.
We do not sell your personal data to any third party, and we do not share it with third parties beyond those listed above.
8. Amazon Redirect Links
When a reader follows a ReviewLinker redirect link, we detect their approximate country (using request headers — we do not store IP addresses) and redirect them to the appropriate Amazon marketplace. We log the destination marketplace, general country, and traffic source (link or QR) for analytics purposes.
We do not store any personally identifiable information about readers who follow redirect links.
