This policy explains what DoseDyno collects, how the app uses that information, and the choices you have. DoseDyno does not sell personal information. Your meal photos, nutrition logs, profile, and Apple Health information are not used to target advertisements.

I. Information We Process

  • Account information: Firebase user ID, display name, email address when you use email or Apple sign-in, language, timezone, and subscription status.
  • Profile and nutrition information: age or birth year, sex, height, weight, goals, dietary preferences, health conditions you choose to enter, meal logs, nutrient totals, supplement inventory, and reminder settings.
  • Apple Health information: with your permission, selected activity, sleep, heart-rate, height, body-mass, and nutrition data. DoseDyno may store summaries needed to create app reports. Apple Health permissions are optional and can be changed in iOS Settings.
  • Photos: meal and supplement-label photos you choose to upload for analysis.
  • Purchase and device information: StoreKit transaction identifiers and signed transaction data used to verify subscriptions, plus Firebase Cloud Messaging tokens used to deliver notifications.
  • Advertising information: when advertising is enabled, Google's AdMob SDK may process IP addresses, app- or device-bounded identifiers, diagnostic and performance data, ad impressions, and ad interactions to deliver and measure advertisements and prevent fraud.

II. How We Use Information

We use this information to authenticate your account, sync your data, estimate nutrition from photos, maintain supplement inventory, create structured summaries, verify purchases, deliver reminders, prevent abuse, troubleshoot failures, and operate the service. DoseDyno outputs are informational estimates and are not medical diagnoses.

III. Cloud and AI Processing

DoseDyno is not an on-device-only service. Account data, app records, health summaries, and uploaded photos are processed through Google Firebase services, including Authentication, Firestore, Storage, Cloud Functions, App Check, and Cloud Messaging. Meal photos, supplement-label photos, and relevant text prompts may be sent by our server to our AI model provider for analysis. Apple processes HealthKit permissions, Sign in with Apple, and StoreKit purchases under Apple's terms. Service providers process data only to provide their contracted services to DoseDyno.

Free accounts may see a Google AdMob native advertisement while a photo is being analyzed. DoseDyno requests non-personalized ads and does not send meal photos, nutrition information, profile details, account IDs, or Apple Health data as ad-targeting parameters. The analysis continues independently of advertising, and results do not require viewing or clicking an ad. PRO accounts do not see these analysis advertisements. Google manages advertising under its Privacy Policy.

IV. Retention and Deletion

Small meal-photo thumbnails may be retained with your food logs and synced to your other devices. The app also keeps protected local previews to display your history offline. Original analysis uploads are normally removed after processing; a failed cleanup may require a later retry.

We retain account data and uploaded content while your account is active, unless a shorter period is required for operational or legal reasons. You can choose Delete Account in the app settings to request deletion of your DoseDyno account data, uploaded files, notification token, and authentication account. Data already written to Apple Health is controlled through Apple Health and may need to be deleted there separately. Limited security, transaction, or deletion records may be retained where required to prevent fraud, complete deletion, restore an eligible active App Store purchase, or comply with law. Deleting a DoseDyno account does not cancel an App Store subscription; subscriptions must be managed separately through Apple.

V. Security

We use access controls, encrypted network transport, platform authentication, App Check, and provider-managed encryption at rest. No system can guarantee absolute security. Do not upload information you do not want processed by the service.

VI. Your Choices and Rights

You can manage camera, notification, and Apple Health permissions in iOS Settings. Depending on your region, you may also have rights to access, correct, delete, or obtain a copy of personal information and to object to or restrict certain processing. Contact us to make a request. We may need to verify your identity before completing it.

Where required, Google's User Messaging Platform asks for your advertising privacy choices before ads are requested. You can reopen Ad privacy choices in the app's Profile screen when this option is required. DoseDyno does not request permission for cross-app tracking.

VII. Children and Changes

DoseDyno is intended for people aged 18 and older. We may update this policy as the service changes. Material changes will be reflected by a new effective date or an in-app notice where appropriate.
