Privacy Policy
This document applies now and is published while a final solicitor review is completed. The practices it describes are accurate as of the last-updated date below.
Data controller: EI Portal Ltd ("we", "us", "our")
Applies to: eiportal.com, beta.eiportal.com and related EI Portal services
Last updated: 15 July 2026
Governing law: England & Wales (UK GDPR & Data Protection Act 2018)
1. Who we are
EI Portal Ltd is the controller of personal data processed through the Service. We are a company registered in England and Wales (company number 17251905), registered office Warwick Place, Bognor Regis, West Sussex, PO22 7PX.
We are registered with the UK Information Commissioner's Office (ICO), registration number ZC198763.
For any privacy question, or to exercise your rights, contact us at info@eiportal.com.
2. The personal data we collect
We aim to collect as little personal data as possible. Depending on how you use the Service, we may process:
| Category | Examples | Source |
|---|---|---|
| Identity & access data | Email address used to authenticate beta access; display name; the plan/tier assigned to you | You / your access provider |
| Feedback data | The content of any feedback, bug report or message you submit, plus your email, current plan and the tool or section you selected | You |
| Usage & analytics data | Pages viewed, approximate location (country/region), device/browser type, referring page, anonymised performance metrics | Collected automatically |
| Technical & log data | IP address, request metadata, security events, timestamps | Collected automatically |
| Tool inputs | The engineering values you type into calculators/tools | You |
| Communications | Emails and messages you send us | You |
Tool inputs. The Service currently has no persistent user database: the values you enter into Tools are processed in your browser to produce results and are not stored on our servers after your session, except to the extent they appear in any Feedback you choose to send us. This will change when accounts, saved projects and similar features launch — this policy will be updated, and this section will describe what is stored, where and for how long.
We do not intentionally collect special-category data (e.g. health, biometric or political data). Please do not submit such data through the Service.
3. How and why we use your data (purposes and lawful bases)
| Purpose | Lawful basis (UK GDPR Art. 6) |
|---|---|
| Authenticate and grant access to the beta / your account | Contract (Art. 6(1)(b)) and/or legitimate interests (Art. 6(1)(f)) in operating access control |
| Provide, operate and maintain the Service and its Tools | Contract / legitimate interests |
| Respond to and act on your feedback, questions and support requests | Legitimate interests in supporting and improving the Service |
| Understand usage and improve the Service (analytics) | Legitimate interests in maintaining and improving the Service (using privacy-friendly, cookieless analytics) |
| Keep the Service secure and prevent misuse | Legitimate interests in security; legal obligation where applicable |
| Comply with our legal obligations | Legal obligation (Art. 6(1)(c)) |
| Send service or administrative communications | Contract / legitimate interests |
| Marketing communications (if any, in future) | Consent (Art. 6(1)(a)) — you can withdraw at any time |
Where we rely on legitimate interests, we have considered the impact on you and do not use your data in ways you would not reasonably expect or that override your rights.
4. Who we share your data with (processors and recipients)
We do not sell your personal data. We share it only with service providers ("processors") who act on our instructions, and where required by law. Our key providers are:
- Vercel Inc. — hosting and delivery of the Service, and privacy-friendly Vercel Web Analytics (which does not use cookies and does not track individuals across sites).
- Cloudflare, Inc. — access control (Cloudflare Access processes your email to authenticate you), content delivery, and security/anti-abuse.
- Slack Technologies, LLC (a Salesforce company) — the feedback, bug reports and messages you submit through the Service are delivered to, and stored in, our private Slack workspace so we can review and act on them.
We may also disclose personal data: to professional advisers; to a buyer or successor in the event of a sale, merger or reorganisation of our business; and to regulators, law-enforcement or others where required by law or to protect our rights, users or the Service.
5. International transfers
Some of our providers (including Vercel and Cloudflare) are based in, or process data in, the United States and other countries outside the UK. Where personal data is transferred outside the UK, we rely on an appropriate safeguard recognised under UK data-protection law — such as UK "adequacy" regulations, the UK Addendum to the EU Standard Contractual Clauses, or the UK Extension to the EU–US Data Privacy Framework — so that your data receives an equivalent level of protection. You can ask us for more detail at info@eiportal.com.
6. How long we keep your data
We keep personal data only for as long as necessary for the purposes above:
- Access/identity data: for as long as you have access to the Service, and a reasonable period afterwards.
- Feedback and communications: for as long as needed to act on them and for a reasonable period for our records.
- Analytics/log data: for a limited period in line with our providers' standard retention.
We then delete or anonymise the data.
7. Your rights
Under UK data-protection law you have the right to:
- access a copy of your personal data;
- rectify inaccurate or incomplete data;
- erase your data ("right to be forgotten") in certain circumstances;
- restrict or object to certain processing (including processing based on legitimate interests, and any direct marketing);
- data portability for data you provided, where applicable; and
- withdraw consent at any time where we rely on consent.
To exercise any right, email info@eiportal.com. We will respond within one month (extendable for complex requests). There is normally no charge.
You also have the right to complain to the ICO (ico.org.uk, helpline 0303 123 1113), though we'd appreciate the chance to resolve any concern first.
8. Cookies and similar technologies
The Service uses a small number of strictly-necessary cookies/local storage (for example to keep you signed in and remember your theme preference), and cookieless analytics. Full detail is in our Cookie Policy.
9. Security
We use technical and organisational measures appropriate to the risk — including access controls, encryption in transit (HTTPS), and reputable infrastructure providers — to protect personal data. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.
10. Children
The Service is intended for professional use and is not directed at, or intended for, anyone under 18. We do not knowingly collect data from children.
11. Automated decision-making
We do not carry out automated decision-making that produces legal or similarly significant effects on you within the meaning of UK GDPR Art. 22.
12. Changes to this policy
We may update this policy from time to time. The "Last updated" date shows the latest version, and we will tell you about material changes by an appropriate means.
