Sommster Privacy Policy
Welcome to Sommster. We believe in providing an intelligent wine companion while maintaining strict respect for your privacy. This policy outlines exactly what data leaves your device and why.
Device Identifiers & Timezone (For Rate Limiting): To enforce daily usage quotas and protect our backend infrastructure, Sommster automatically retrieves an anonymous device identifier and your local timezone. This is stored temporarily in our secure cloud environment strictly for rate-limiting and is not used for cross-app tracking.
Camera and Photo Access (For OCR): Sommster requests camera access strictly to allow you to photograph wine labels. Image data is transmitted securely to third-party AI services solely for Optical Character Recognition (OCR). Images are not used for facial recognition, sold, or retained permanently.
Location Data (For Finding Wineries): If you search for local wineries, Sommster requests location access to determine your geographic area. This data is transmitted to routing services to fetch results in real-time, is not linked to your identity, and is not stored.
AI Prompts & Preferences: Text inputs and taste filter preferences (such as price, vintage, distance, and organic status) are transmitted to third-party Large Language Model providers to generate sommelier advice. We restrict our AI partners from using your prompts to train their public models.
Local Data Storage (Your Wine Cellar & Winely): Your saved wine collection, tasting notes, and Winely game results are saved locally on your device. Your private cellar data is not harvested or synced to a central company database.
In-App Purchases: We use third-party services (Apple App Store, Google Play, and RevenueCat) to process secure payments and manage your subscription status.
Transaction Data: Anonymous transaction identifiers and basic device telemetry (operating system version, device model, and locale) are shared securely with these payment processors. No personal financial information is ever processed or stored on Sommster's servers.
External Links: Sommster contains outbound links to third-party websites (such as Wine-Searcher and Google). We are not responsible for the privacy practices of those external sites.
No User Accounts: We do not collect names, emails, passwords, or phone numbers.
No Ad Tracking: We do not use third-party advertising networks or share data with data brokers.
No Passive Analytics: We do not utilize background crash reporting SDKs that passively collect device data.
