Cookie Policy

Last updated September 2026

A short account of the few cookies this site relies on — to hold your bag, remember your language and show prices in your currency — and how to control them.

  1. 01 What cookies are
  2. 02 Essential cookies
  3. 03 Measurement
  4. 04 Managing cookies
  5. 05 Further information

01What cookies are

Cookies are small files placed on your device, together with similar storage kept by your browser. They allow the site to remember your choices between pages and visits. We use as few as the service allows.

02Essential cookies

These are required for the boutique to work and cannot be switched off.

  • Your bag — keeps the pieces you have selected until checkout.
  • Language and market — remembers the language you read in and the country and currency you shop in.
  • Sign-in — keeps your private client session open and secure while you are signed in.
  • Checkout and payment — set by our commerce and payment providers to complete your order safely and prevent fraud.

03Measurement

We look at anonymous, aggregated figures — which pages are read, how quickly they load, and where errors occur — so that we can improve the site. These figures do not identify you and are never used to build an advertising profile.

04Managing cookies

Every browser lets you see, delete and refuse cookies in its privacy or settings menu. Refusing the essential ones will prevent the bag, sign-in and checkout from working. You can also clear the site's stored data at any time; you will then be asked again for your language and market.

05Further information

Our Privacy Policy explains what we do with the personal data behind these cookies. For any question, write to enquiries@astrealondon.com or to Astrea London Limited (company number 15268228), The Fairmont Windsor Park, Bishopsgate Road, Egham, TW20 0YL, United Kingdom.
