This page sets out both the Privacy Policy and the Terms of Use for Tax Efficiency Lab (taxefficiencylab.com). By using this website, you agree to both.
Privacy Policy
This Privacy Policy explains how we collect, use and protect information when you visit this website. We are committed to handling your data transparently and lawfully.
Who we are (Data Controller)
The data controller responsible for this website is Oscar Nevokhel, operating Tax Efficiency Lab from Spain. For any privacy-related request, contact [email protected].
Information we collect
Information you provide: when you email us, we receive your email address and the contents of your message.
Information collected automatically: like most websites, our hosting and security systems automatically log technical data such as your IP address, browser type, device information, referring page and the date and time of your visit. This is used for security, troubleshooting and aggregate statistics.
Cookies and tracking
We may use: (a) essential cookies needed for the site and its caching and security to function; (b) analytics cookies that help us understand, in aggregate, how visitors use the site; and (c) third-party cookies set by affiliate networks and external services when you click certain links. You can control or delete cookies through your browser settings, and where required by law we ask for your consent before setting non-essential cookies.
How we use your information and legal bases
We process personal data to respond to your enquiries (legal basis: your consent or steps taken at your request); to operate, secure and improve the website (our legitimate interests); to comply with legal obligations; and to measure aggregate traffic (consent, where required). These legal bases are those set out in the EU/UK General Data Protection Regulation (GDPR).
Affiliate links
Some links on this site are affiliate links. When you click them, the third-party network may set cookies and process your data under their own privacy policies. Please see our Affiliate Disclosure for more detail.
Sharing and third parties
We do not sell your personal data. We share data only with service providers that help us run the site — such as our hosting provider, caching and security services, backup tools, and analytics or search providers (for example, Google). These providers process data on our behalf or as independent controllers under their own privacy policies.
International data transfers
Some of our service providers, and much of our audience, are located outside the European Economic Area, including in the United States. Where personal data is transferred internationally, we rely on appropriate safeguards such as the EU Standard Contractual Clauses or equivalent mechanisms.
Data retention
We keep email correspondence only as long as needed to handle your request and for a reasonable period afterwards. Server logs and aggregate analytics are retained for limited periods consistent with security and statistical purposes.
Your rights (EEA & UK – GDPR)
You have the right to access, rectify, erase, restrict or object to the processing of your personal data, to data portability, and to withdraw consent at any time. You may also lodge a complaint with your supervisory authority — in Spain, the Agencia Española de Protección de Datos (AEPD, www.aepd.es). To exercise any right, email [email protected].
Your rights (United States – California / CCPA)
If you are a California resident, you have the right to know what personal information we collect, to request its deletion, and to opt out of the “sale” of personal information. We do not sell personal information. You may exercise these rights using the contact details above, and we will not discriminate against you for doing so.
Children’s privacy
This website is intended for adults and is not directed to children under 16. We do not knowingly collect personal data from children.
Security
We take reasonable technical and organisational measures to protect your information. However, no method of transmission over the internet or electronic storage is completely secure.
Terms of Use
By accessing or using this website, you agree to these Terms of Use. If you do not agree, please do not use the site.
Educational purpose only
All content on Tax Efficiency Lab is provided for general informational and educational purposes. It does not constitute tax, legal, accounting, investment or financial advice, and must not be relied upon as a substitute for advice from a qualified professional familiar with your specific circumstances.
No professional relationship
Reading this site or contacting us does not create any advisor–client, attorney–client or fiduciary relationship.
Accuracy and currency
Tax law changes frequently and varies by individual situation. While we build our guides from primary sources and state our “last verified” dates, we make no warranty that the information is complete, current or error-free. You are responsible for verifying any figure against official sources before acting.
No warranties
The site is provided “as is” and “as available”, without warranties of any kind, express or implied, including fitness for a particular purpose.
Limitation of liability
To the fullest extent permitted by law, Tax Efficiency Lab and its operator shall not be liable for any loss or damage arising from your use of, or reliance on, the content of this website.
External and affiliate links
This site contains links to third-party websites, some of which are affiliate links (see our Affiliate Disclosure). We are not responsible for the content, accuracy or practices of third-party sites.
Intellectual property
Unless otherwise stated, the content on this site is owned by Tax Efficiency Lab and may not be reproduced or republished without permission. You may share short excerpts with clear attribution and a link to the original page.
Changes
We may update this page at any time. Continued use of the site after changes means you accept the revised Privacy Policy and Terms.
Governing law and jurisdiction
These Terms are governed by the laws of Spain. Any dispute arising from or relating to these Terms or your use of the website shall be subject to the exclusive jurisdiction of the courts of Spain, without prejudice to any mandatory consumer-protection rights you may have under the law of your country of residence.
