This policy is written in accordance with the UK General Data Protection Regulation (UK GDPR), the Data Protection Act 2018, the Privacy and Electronic Communications Regulations 2003 (PECR), and the Data (Use and Access) Act 2025 (in force from 5 February 2026).
NestWise is a free consumer education and Cash ISA rate comparison website. We publish information about savings rates and provide links to third-party financial product providers via affiliate partnerships. We do not collect personal contact details, sell financial products, or provide regulated financial advice.
When you click an "Apply" link on this site, you are redirected to a third-party provider's website where their own terms and privacy policy apply.
| Data | Purpose | Legal basis (UK GDPR) |
|---|---|---|
| IP address, browser type, pages visited, referring URL | Website security, server-side logging, and aggregated traffic analysis | Art. 6(1)(f) — Legitimate interests |
| Outbound click data (which rate link was clicked, timestamp, referring page) | Affiliate commission attribution and content performance measurement | Art. 6(1)(f) — Legitimate interests |
| Cookie consent preference (stored in browser localStorage) | Remembering your consent choice so we do not ask again | Art. 6(1)(c) — Legal obligation (PECR) |
We do not collect your name, email address, or phone number. No personal contact details are submitted through this website.
NestWise earns affiliate commission when a user clicks a rate link on this site and subsequently applies for a product at a partner provider. This commission is paid by the provider and does not affect the rate or terms you receive.
Links marked "Apply" are affiliate links. Clicking them redirects you to the provider's own website. We are not responsible for the content, accuracy, or privacy practices of third-party sites. We recommend you review the provider's privacy policy before submitting any personal information to them.
Our affiliate relationships include rate comparison networks and direct partnerships with UK savings providers. Rates displayed on this site are sourced from MoneyFacts and updated regularly, but may not always reflect the current live rate.
We do not sell, rent, or share personal data with third parties for marketing purposes. Aggregated, non-identifiable click data is shared with affiliate networks solely to attribute and process commission payments.
We use Vercel Inc. (San Francisco, CA, USA) as our hosting provider. Vercel processes server log data as part of standard hosting operations. Transfer to the USA is covered by Standard Contractual Clauses (UK Addendum to EU Commission decision 2021/914).
We use only a single essential preference stored in localStorage to remember your cookie consent choice. We do not use advertising or analytics cookies. See our Cookie Policy for full details.

To exercise any right, contact us at hello@sitelightning.com. We will respond within one calendar month.
If you are dissatisfied with how we handle your data, you may lodge a complaint with the Information Commissioner's Office (ICO) at ico.org.uk.
We do not use personal data for automated decision-making or profiling that produces legal or similarly significant effects.
Where data is transferred outside the UK (e.g. to Vercel's US infrastructure), we rely on Standard Contractual Clauses (UK Addendum) to ensure appropriate safeguards.
We may update this policy from time to time. Changes will be posted on this page with an updated date at the top.
