Cookie Policy

Cookies are small text files that are downloaded and stored on your computer, smartphone, or tablet when you visit a web page. They allow the website to remember your actions and preferences over time, so you don't have to keep re-entering them.

In addition to traditional cookies, we also use related browser storage technologies including localStorage, sessionStorage, IndexedDB, and the browser Cache API — primarily to cache AI model weights for fast try-on loading.

We use cookies and local storage to streamline and accelerate the interactive parts of our website, including:

• Keeping you logged in during your shopping session.
• Remembering which products you added to your virtual try-on tray.
• Tracking affiliate referral channels so partner merchants can credit our commission.
• Measuring website performance and catching script errors.
• Caching AI model weights (MediaPipe, background-removal WASM) for fast subsequent loads.

• Strictly Necessary: Essential for login, site security, and loading core UI. Cannot be disabled without breaking core functionality.
• Functional & Preferences: Customise your experience (e.g., dark mode, saved try-on items, language preference).
• Performance & Analytics: Anonymous counters that show us which try-on categories are most popular and identify slow scripts.
• Advertising / Targeting: Used by Meta Pixel to measure ad campaign conversion. Does not identify you personally.
• Affiliate / Referral: Placed by merchant partners when you click through, to validate our referral commission.

We use Google Analytics to evaluate site performance and understand how visitors interact with Trevia Shopping. Google Analytics collects:

• Anonymised IP addresses (IP anonymisation is enabled).
• Pages visited, session duration, and traffic sources.
• Device type, browser, and operating system (aggregated).
• Conversion events such as affiliate link clicks.

Data collected by Google Analytics is processed by Google in accordance with their Privacy Policy. You can opt out using the Google Analytics Opt-out Browser Add-on.

We may use the Meta (Facebook) Pixel to measure the effectiveness of our advertising campaigns. The Meta Pixel:

• Tracks when users complete specific actions (e.g., clicking an affiliate product link) after seeing a Trevia ad on Meta platforms.
• Allows us to build anonymised lookalike audiences for marketing purposes.
• Does not receive any camera data, uploaded photos, or personally identifiable try-on information.

Meta's data practices are governed by their own Privacy Policy. You can manage Meta ad preferences in your Facebook account settings.

Our Virtual Try-On feature performs real-time face tracking and background removal in your browser using heavyweight Machine Learning weights (MediaPipe models and @imgly/background-removal WASM). To speed up your experience:

• On your first try-on, your browser downloads these models — this may take a few seconds.
• These models are then cached in your browser's IndexedDB and Cache Storage.
• On all subsequent visits, try-on loads near-instantly from local cache.
• No personal photos, camera inputs, or biometric data are stored inside this cache.

To clear these cached models, open your browser's Developer Tools → Application → Storage → Clear site data.

You can control and manage cookies in several ways. Note that blocking essential cookies may prevent parts of the try-on widget from working correctly.

• Browser Settings: Block or delete cookies directly inside Chrome, Safari, Edge, or Firefox privacy settings.
• Clearing Site Data:To clear ML model caches, use your browser's "Clear site data" option in Developer Tools or history settings.
• Google Analytics Opt-Out: Install the Google Analytics Opt-Out Add-on.
• Meta Ad Preferences:Manage targeting via your Facebook account → Settings → Ads.
