Overview
Stack My Med collects information needed to provide the app: account access, label scanning, product cabinet storage, scheduling, adherence tracking, optional HealthKit context, subscription status, support, and diagnostics.
We do not sell personal information. Data is used to operate, secure, improve, support, and measure Stack My Med.
Our public website uses Google Analytics 4 to understand visits, traffic sources, page views, outbound clicks, and App Store download clicks. Google may process browser and device information, approximate location, referrer, IP address, and interaction events for analytics. We use this to improve the website, not for third-party advertising tracking in the app.
We use aggregate backend usage reports to understand privacy-safe product usage such as active users, scan volume, schedule refreshes, dose logging, and subscription status. These reports do not include product names, label photos, health answers, free-text notes, or dosage text.
If we run Meta app-install advertising, Stack My Med may use Meta and RevenueCat to measure app activation, trial starts, subscriptions, and renewals attributed to those campaigns. We do not send supplement or medication names, label photos, dosage text, health answers, HealthKit values, free-text notes, email addresses, or phone numbers to Meta for this advertising measurement.
Medical and supplement information in Stack My Med is informational only. It is not a diagnosis, treatment plan, or substitute for professional medical advice.
Data we collect
Account and identifiers
When you sign in, we may process your Apple Sign in name or email when Apple provides it, a Convex user ID, anonymous user ID, auth identifiers, device-related identifiers, push notification metadata, and live activity token hashes.
Health and profile information
If you provide it, Stack My Med stores self-reported profile answers such as age range, goals, lifestyle information, conditions or concerns, pregnancy status, and similar health-related context. If you connect Apple Health, the app may read summaries such as steps, heart rate, sleep, and active calories to show context around your routine.
Label photos and product records
When you scan a product, label photos, extracted product facts, supplement or medication names, dosage, ingredients, schedule entries, cabinet assignments, adherence events, and related scan metadata may be stored off-device so the app can work across sessions.
Purchases and usage
We store subscription entitlement state, App Store transaction identifiers, scan counts, privacy-safe feature usage metrics, AI audit events, backend failures, diagnostics, and limited device attribution identifiers needed to operate, debug, and measure the service.
