1. Controller
Gianni Hernandez Barker, self-employed, NIF 45852355S, address Rúa Mozart 2, 1º B, 15008 A Coruña, Spain, trading as Byron-Butler. Contact: info@byronbutler.com.
2. What data we process, why and on what legal basis
- Free diagnosis and contact: name, email, phone (optional), business, website and whatever you tell us, to prepare your diagnosis and reply to you. Legal basis: your consent (art. 6.1.a GDPR) and pre-contractual steps at your request (art. 6.1.b).
- "Where did you hear about us?": an optional answer we use only to learn which channels work. Legal basis: your consent.
- Clients: contact and billing details to provide the service, issue invoices and support you. Legal basis: performance of the contract (art. 6.1.b) and tax obligations (art. 6.1.c).
- Payments: card payments are processed by Stripe; we never see or store your card details. Legal basis: performance of the contract.
- Analytics (Google Analytics): only if you accept analytics cookies. Legal basis: your consent.
- Our own visit statistics: we count page views without cookies, using a one-day encrypted identifier derived from the IP and browser, which can't recognise you from one day to the next; the IP is not stored. Legal basis: legitimate interest in understanding how the website is used (art. 6.1.f).
- Security: Google reCAPTCHA on forms and a technical log (IP, date and time of form submissions and panel access, with the email partly hidden) deleted after 12 months. Legal basis: legitimate interest in the site's security (art. 6.1.f).
3. Data of our clients' customers
When a client's website and panel store data about their own customers, that client is the controller and we act as processor, under article 28 GDPR and the terms of service. If you are a customer of one of our clients, contact them to exercise your rights; we will help them assist you.
4. How long we keep data
Diagnosis requests that don't lead to a contract, up to 12 months after the last contact. Client data, for as long as the relationship lasts and then for the legal periods (in particular tax periods, generally six years). Security logs, 12 months.
5. Recipients
We don't share your data with third parties unless required by law. Only the providers needed to deliver the service process it, as processors:
- Web hosting and email provider: where the website, panel and email run. Its servers are in the United Kingdom, which has a European Commission adequacy decision and therefore offers a level of protection equivalent to the European Union's.
- Stripe: card payments and recurring fees.
- Google: Google Analytics (only with your consent) and reCAPTCHA.
- Spanish Tax Agency and other authorities: when required by law.
Some of these providers are in the United States. Those transfers rely on the EU-US Data Privacy Framework or the European Commission's standard contractual clauses.
6. Your rights
You can exercise your rights of access, rectification, erasure, objection, restriction and portability by writing to info@byronbutler.com. Where processing is based on consent, you can withdraw it at any time. We don't make automated decisions or profile you. If you think we haven't handled your data properly, you can complain to the Spanish Data Protection Agency (www.aepd.es).
