1. What Are Cookies
Cookies are small text files that a website places on your device when you visit. They are widely used to make websites work, work more efficiently, and provide information to the website owner. Some technologies covered by this policy are not strictly "cookies" — for example local storage and similar browser APIs — but they serve the same purpose, and this policy applies to them in the same way.
2. Types of Cookies We Use
AirPurchase uses the following categories of cookies and similar technologies:
• Strictly necessary: required for the platform to function — for example to keep you signed in, to honour your CSRF/security tokens, and to retain shopping-cart-style state between page loads. You cannot opt out of these without breaking the service.
• Functional / preference: remember your choices such as language (en / zh), theme (light / dark / system), and market region. These are non-essential but improve the experience materially.
• Analytics: anonymous, aggregated usage data that helps us understand what works and what does not. We use Google Analytics 4 when configured. Analytics cookies do not identify you personally.
• Security / bot protection: when contact forms are submitted we may set short-lived tokens (e.g. Cloudflare Turnstile) to confirm you are not a bot.
• Third-party integrations: when a page embeds a YouTube video, WhatsApp button, Xero connect flow, or similar, those providers may set their own cookies under their respective policies.
3. Cookies We Set Directly
Representative examples — the exact set evolves over time:
• `theme` (localStorage) — your light / dark / system preference. Persists until cleared.
• `locale` / language preference — selected via the language switcher.
• Session cookies for the AirPurchase admin / app — required for login. Expire when you log out.
• CSRF / anti-tamper tokens — set on request, expire after the page transaction completes.
4. Third-Party Cookies
We rely on the following third-party services, each governed by its own privacy and cookie policies:
• Google Analytics 4 — analytics. (https://policies.google.com/technologies/cookies)
• Cloudflare — performance, security, and (when configured) image resizing.
• Xero — accounting integration for customers who connect Xero accounts.
• WhatsApp Business / Meta — the "Book a Demo via WhatsApp" link redirects to WhatsApp's domain.
• YouTube / Vimeo — embedded product demo videos may set cookies on play.
These third parties may set their own cookies that we do not control. Please consult their respective policies for details.
5. Your Choices
You can control cookies in several ways:
• Browser settings: most browsers allow you to refuse all cookies, accept only first-party cookies, or be notified before a cookie is stored. Refer to your browser's help for instructions.
• Do Not Track: AirPurchase respects browser DNT signals where technically practical, but DNT is not an industry-wide standard.
• Opt-out tools: for Google Analytics, you can install the official opt-out browser add-on at https://tools.google.com/dlpage/gaoptout.
Disabling strictly-necessary cookies may prevent core parts of the platform from working.
6. Data Collected via Cookies
Cookies enable us to collect limited information such as your device type, browser type, IP address (truncated where possible), and pages visited on our site. This data is used in accordance with our Privacy Policy and the Personal Data (Privacy) Ordinance of Hong Kong (Cap. 486).
7. Retention
Cookie lifetimes vary:
• Session cookies are removed when you close your browser.
• Persistent cookies remain until they expire or until you clear them. Most of our persistent cookies expire within 13 months.
• Analytics retention is governed by the analytics provider's configuration (Google Analytics: typically 14 months at AirPurchase).
8. Changes to This Policy
We may update this Cookie Policy from time to time. The "Last updated" date at the top of this page reflects the most recent revision. For material changes we will provide additional notice (for example, a banner on the website).
