What we collect, and why

When you use our contact form

We ask for your name, your email address and your message. We use them only to read your enquiry and reply to it.

When you complete our client questionnaire

The questionnaire asks for your name and an email address for our reply, and then for information about your business: the company and trading name, what the business does, how long it has traded, the number of employees, the number and location of sites, your energy supplier and contract end date, your broadband and phone provider and contract end date, your card payment provider, your transaction rates, the split between card and cash sales, your main stock or wholesale suppliers, the stage the business is at, your target launch date, your main competitors, how the business is priced and when pricing was last reviewed.

Most of that is business information rather than personal information, but it is commercially sensitive, and where it identifies you it is treated as personal data. We use it for one purpose: to understand your position well enough to tell you whether we can help and what the work would cost.

When you book a call

Bookings are handled by Calendly. When you book, Calendly collects your name, email address and telephone number, and passes the appointment details to us.

Automatically, when you visit

Our hosting provider keeps standard server logs: your IP address, your browser type, the pages you requested and the time you requested them. These exist for security and for diagnosing faults.

We do not use Google Analytics, or any other analytics or advertising tracking, anywhere on this website.

Where your information goes

Anything you send through a form is emailed to info@siliyan.co.uk and is also stored in this website's database, where our administrators can read it. Copies of the emails the site sends are kept in a log in the same database.

Cookies

A cookie is a small file that a website asks your browser to store. We set no cookies at all until you choose through the banner shown on your first visit. If you make no choice, nothing beyond the essentials is stored.

Essential: a record of your own cookie choice, so that we do not ask you again.
Functional: set by Calendly if and when the booking calendar loads on the contact page. Without them the calendar cannot work.
We use no advertising or tracking cookies of any kind.

You can change or withdraw your choice at any time through the cookie settings on this site, and you can delete cookies in your browser at any time.

Who else is involved

We keep this list as short as we can. It is currently:

Hostinger International, which hosts this website and our email. European Union.
Calendly, which runs the booking calendar and takes the appointment details. United States.
Google Fonts, which serves the typefaces the site is displayed in. United States.

Calendly and Google receive your IP address as a necessary part of delivering those services, and both are outside the United Kingdom. Transfers of that kind are covered by the approved safeguards for international transfers.

We do not sell your information and we do not share it with anyone for marketing. If we need to bring in a specialist to work on your matter, or to approach a supplier on your behalf, we will tell you first, and nothing about you goes to a supplier without your agreement.

How long we keep it

Enquiries that do not lead to work: twelve months, then deleted.
Records for clients we have worked with: six years after the engagement ends, which reflects the normal UK tax and limitation periods.
Server logs: kept by our host for a short period as part of normal operation.

Our lawful basis

Under UK GDPR we rely on the following.

Taking steps at your request before entering a contract, which covers your enquiry, the questionnaire and your booking.
Legitimate interests, which covers keeping a record of who we have spoken to and running the site securely. We have weighed this against your interests and do not believe it overrides them.
Consent, for non-essential cookies only. You can withdraw it whenever you like.

Your rights

You can ask us for a copy of the personal information we hold about you, ask us to correct it, ask us to delete it, object to or restrict how we use it, and ask to receive it in a portable form. Email info@siliyan.co.uk and we will respond within one month.

If you are unhappy with how we have handled your information you can complain to the Information Commissioner's Office, the UK regulator, at ico.org.uk or on 0303 123 1113. We would rather you came to us first so that we can put it right.

Changes to this policy

If we change how we handle information we will update this page and change the date at the top.
