Sienda Ltd
Company No. 08194971
Third Floor, 207 Regent Street, London W1B 3HH, United Kingdom
Privacy contact: privacy@siendaweblines.com
Scope
This policy explains how Sienda Ltd handles personal data when you visit sienda.co.uk, contact the company or enter into a professional relationship with us. Sienda acts as data controller where applicable and seeks to comply with the UK GDPR, the Data Protection Act 2018 and, where applicable, the EU GDPR.
Data we may process
Depending on the context, we may process identity and business contact information, correspondence, information supplied in connection with an enquiry or assignment, limited technical information normally generated when a website is requested from its hosting infrastructure and, where Analytics has been explicitly accepted, website-usage information supplied through Google Analytics.
How data is obtained
Information may be supplied directly by you, arise from our professional communications, come from lawful public or professional sources where relevant to legitimate business activity, or be generated through website use where the relevant processing is permitted. The Sienda website itself does not contain an embedded enquiry form.
Why we process data
- To respond to enquiries and discuss potential assignments.
- To provide agreed professional services and administer engagements.
- To maintain business records and meet legal or regulatory obligations.
- Where lawful, to conduct relevant business-to-business professional communications.
- Where you have consented, to understand website usage and improve sienda.co.uk through Google Analytics.
The lawful basis will depend on the circumstances and may include performance of a contract, steps requested before entering into a contract, legitimate interests, legal obligation or consent.
Professional communications and direct marketing
Sienda may use limited business contact information for relevant professional communications where this is lawful. Recipients can object to direct marketing at any time. We do not sell personal data for third-party marketing.
Google Analytics
The website is prepared to use Google Analytics only where a measurement ID has been configured and the visitor has explicitly accepted Analytics. Analytics is off by default and the Google Analytics script is not loaded before consent. If no measurement ID is configured, Analytics is not active on that deployment.
Where Analytics is enabled with consent, Google may process information about website use and set measurement cookies. The purpose is to provide aggregated information that helps Sienda understand and improve the website, not to provide behavioural advertising. You can withdraw Analytics consent at any time through the Cookie settings link in the footer.
Sharing and processors
Personal data may be handled by service providers that support ordinary business operations, communications, hosting, analytics where consented to, or professional work. Where required, appropriate contractual and data-protection safeguards are used. Data may also be disclosed where required by law or competent authority.
Retention
Information is kept only for as long as reasonably necessary for the purpose for which it was collected, including legal, contractual, accounting, professional-record or suppression-list requirements. Analytics retention is governed by the configuration applied to the relevant Google Analytics property.
Your rights
Depending on the applicable law and circumstances, you may have rights of access, rectification, erasure, restriction, portability, objection and withdrawal of consent. Requests can be sent to the privacy contact above. You may also have the right to complain to the UK Information Commissioner’s Office.
Website technology
Sienda.co.uk is a static, privacy-conscious implementation. It does not use advertising pixels, embedded social feeds, embedded maps or embedded video. External services are linked rather than embedded where practical. Optional Google Analytics is controlled by the consent mechanism described above.
Security and third-party links
Reasonable technical and organisational measures are used to protect business information and personal data. Links to external websites are governed by the privacy practices of those third parties.
Changes
This policy may be updated when the website, services, law or data practices change. Last updated: 30 September 2026.
