SugarScout ("we", "the app") is a sugar tracking app for iOS that helps you stay under a daily sugar limit, with optional AI meal scanning. This policy explains what data the app collects, how it is used, and your rights.
All of your tracking data, including daily logs, food entries, your sugar limit and its history, streaks, and preferences, is stored locally on your device. We do not operate a database of your food log. Your tracking data never leaves your device except as described below (barcode lookups, AI meal scanning, purchase verification, analytics, and install attribution).
SugarScout does not require you to create an account, sign in, or provide personal information such as your name, email address, or phone number. To use AI meal scanning, the app receives a server-issued anonymous identifier the first time you scan, used only to secure and rate-limit requests to our service. This identifier is not linked to your real identity.
When you scan a meal, the photo you capture is sent to our backend service, which uses Google Gemini to identify the foods and estimate their sugar content. After processing:
SugarScout requests camera access to scan barcodes on packaged foods and to take meal photos for AI scanning. Barcodes are read on-device; the barcode number (text only, no personal data) is sent to Open Food Facts to look up nutrition information. The camera feed itself is not recorded or stored.
SugarScout offers an optional auto-renewable subscription ("SugarScout Pro"), which may include a free trial. All billing is handled by Apple's App Store; we do not collect or store any payment information. Subscription status is verified through Adapty (and, for older versions of the app, RevenueCat). They receive an anonymous app user ID and your purchase or entitlement status. No name, email address, phone number, or payment details are shared by SugarScout. See Apple's Privacy Policy for how Apple handles purchases.
SugarScout may ask permission to send local notifications, such as daily reminders and subscription offers. Notifications are scheduled on your device and do not involve any external servers.
SugarScout uses PostHog, a product analytics service, to understand how features are used and to improve the app. PostHog collects:
Analytics events are tied to an anonymous, randomly generated identifier stored on your device, not to your name, email address, or any account. PostHog analytics does not use the IDFA, is not used for advertising, and is never sold. Food photos are never sent to PostHog. Data is hosted in the United States. See PostHog's Privacy Policy.
SugarScout uses AppsFlyer to measure which marketing campaigns lead to app installs and subscriptions. AppsFlyer may receive:
If you decline tracking, or turn it off at any time in Settings > Privacy & Security > Tracking, the IDFA is not shared. SugarScout shows no ads. See AppsFlyer's Privacy Policy.
We do not sell your personal data. We share data with third parties only as described above.
SugarScout is not directed at children under the age of 13. We do not knowingly collect personal information from children.
Your tracking data lives on your device, so you can delete it at any time by deleting the app. Anonymous purchase records are kept by Adapty and RevenueCat under their data retention policies. To ask for deletion of analytics or attribution data, email us.
SugarScout provides general nutrition information and is not medical advice. Sugar values, including AI estimates, may be approximate.
We may update this policy from time to time. The "Last updated" date at the top shows the current version.
