Our lawful bases for using personal information
We rely on the following lawful bases under UK data-protection law:
- Legitimate interests: We use business contacts’ information to respond to enquiries, discuss requirements, prepare proposals and manage business relationships. We also use information to maintain and protect our website and systems, prevent misuse and keep appropriate correspondence records. Our legitimate interests are running a secure, effective business and providing relevant services. We consider the impact on individuals and do not rely on this basis where their rights and interests override ours.
- Legal obligation: We use information where necessary to comply with legal requirements, including identity verification and anti-money-laundering checks when an enquiry progresses, required record keeping and responding to lawful requests from authorities.
- Consent: Where required, we obtain consent before using non-essential cookies or sending optional marketing communications. You can withdraw cookie consent through Manage Cookies and marketing consent through the unsubscribe facility or by contacting us. Withdrawal does not affect processing carried out lawfully before consent was withdrawn.
Submitting an enquiry does not subscribe you to marketing communications.
Marketing
Submitting an enquiry does not automatically subscribe you to marketing communications. Where we offer optional marketing communications, the relevant choice will be presented separately and we will comply with the applicable direct-marketing rules.
Who we share information with
Where necessary, information may be shared with organisations providing services to Ardein, including website hosting and IT providers, email and communication services, form/practice-management/business-system providers, identity verification and AML providers, professional advisers, and regulators or authorities where required by law.
We require service providers handling personal information on our behalf to protect it appropriately.
International transfers
Some technology providers may process information outside the United Kingdom. Where personal information is transferred internationally, we will use an applicable UK adequacy arrangement or other recognised safeguard where required.
How long we keep information
Where an enquiry does not become a client engagement, we will normally retain the enquiry and related correspondence for up to 24 months after the last substantive contact, unless there is a legal or regulatory reason to retain it for longer.
If you become a client, relevant information becomes part of the client record and will be retained in accordance with our contractual, accounting, taxation, regulatory and anti-money-laundering obligations.
Your rights
Depending on the circumstances, you may have rights to access your personal information, correct inaccuracies, request erasure, restrict processing, object to processing, receive certain information in a portable format, and withdraw consent where consent is the lawful basis.
Your right to object
Where we rely on legitimate interests to process your personal information, you have the right to object to that processing. We will consider any objection in accordance with data-protection law.
Complaints
Please contact us first if you have concerns about how we use your personal information. You also have the right to complain to the Information Commissioner’s Office (ICO).
