Privacy Policy

WhichCapsule may collect account details such as email address, username and profile image when you sign in. We also store product selections, favorites, ratings, reviews, quiz preferences and basic usage events needed to operate the service.

We do not ask for payment card details and we do not sell products directly inside the application.

When you allow optional analytics, we may record page views, quiz events, result interactions, comparison usage, blog clicks, affiliate clicks, country route, device/browser details and similar usage signals.

We use information to personalize capsule and machine recommendations, show saved products, improve quiz quality, prevent abuse and understand which pages or features are useful.

When you click an external retailer link, the retailer may process your data under its own privacy policy.

WhichCapsule uses Supabase for authentication, database and storage features. We use Vercel for hosting and performance tooling.

If you allow analytics, Google Analytics 4 and Vercel Analytics/Speed Insights may process usage, device, browser, page and performance information.

Advertising services such as Google AdSense may check site eligibility and serve advertising scripts. If you allow advertising and affiliate tracking, optional partner tools may process ad impressions, clicks, device, browser and referral information. Amazon and official store links are controlled by those third parties after you leave WhichCapsule.

External links to Amazon, official stores or other retailers are controlled by those third parties.

You can sign out, update profile information, manage favorites and request account deletion from your profile. Some technical logs may remain for security, fraud prevention or legal compliance.

You can accept, reject or update optional analytics, advertising and affiliate tracking choices from the cookie settings control on the legal pages. Essential cookies for login, security, country and language preferences remain active.
