TrackYourBite is an iPhone and iPad app operated by EulerWorks LLC (Euler Works). It lets you scan receipts, understand food processing, track spending, and manage grocery lists. This policy explains how we handle information when you use TrackYourBite and this website.
1. Information we collect
- Account and sign-in information. When you sign in with Google, we receive your Google account identifier, name, and email address to identify your account. The app also accesses your Google profile photo, when available, to display it in your profile and remembers its URL on your device. When you sign in with Apple, we receive an account identifier and the name and email Apple makes available; this may be an Apple private relay email. We do not receive your Google or Apple password. Guest use creates an app account identifier without requiring a Google or Apple account.
- Receipts and groceries. We process receipt photos you choose to capture or upload, extracted items, prices, stores, purchase dates, food classifications, your corrections, grocery lists, budgets, and preferences. A photo can contain other information printed on your receipt, so avoid uploading information you do not want processed.
- App activity and diagnostics. We collect information such as feature interactions, scan outcomes, request timing, errors, app/device information, and account-linked activity to operate the app, diagnose failures, and understand feature use.
- Notifications, purchases, and support. If you enable notifications, we store a device push token, delivery preferences, and time zone. We receive subscription status and transaction identifiers from Apple to manage Pro access; Apple handles payment details. If you contact us or send feedback, we receive your message and any screenshots or other information you include.
2. Google account data
Google sign-in requests basic profile and email access. We use this information to authenticate you, create or find your TrackYourBite account, show your profile, and associate your saved data with your account. Signing in with Google does not give TrackYourBite access to your Gmail messages, Google Drive files, contacts, or photo library.
We store your Google account identifier, name, and email with your account in our backend database. Authentication tokens are used to verify sign-in and maintain your app session. Google profile information is not used for advertising or sold to third parties. Our use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including its Limited Use requirements.
3. How we use information
We use information to save and analyze receipts, calculate spending and food-processing summaries, maintain grocery lists and preferences, provide enabled notifications, verify subscriptions, answer support requests, protect accounts, and improve app reliability. AI-generated results may be inaccurate; you can review and correct your receipt details in the app.
4. Processing and sharing
We do not sell your personal information. We use service providers to operate TrackYourBite:
- Railway hosts our backend and associated database and file storage, which process and store account information, receipt images, extracted data, and operational records.
- Google Gemini processes receipt images and relevant food or purchase information to extract receipt details and generate food-related analysis. This receipt-processing use is separate from Google sign-in. We do not need your Google password or Gmail access to analyze a receipt.
- Apple and Google provide their respective sign-in services. Apple also processes in-app purchases and delivers push notifications through Apple Push Notification service.
- Website and communications providers process website requests and support or account-related messages as needed to deliver those services.
Authorized personnel may access information as needed for support, service operation, security, and troubleshooting. We may also disclose information with your consent or where necessary to comply with law or protect users and the service. Providers may process information in countries other than where you live.
5. Storage, security, and retention
Account and purchase data are stored on our backend; the app also keeps local session information and cached data to support sign-in and responsive screens. We use encrypted HTTPS connections, authentication, and access controls to protect information. No storage or transmission system is completely secure.
We retain account information and saved content while your account is active and as needed to provide the service. Operational records, backups, and records required for security or legal obligations may remain for longer than the active account data. We do not promise immediate removal from every backup when an account is deleted.
6. Your choices and deletion
You can edit receipt details and grocery lists in the app. To delete your account and associated active account data, open the app menu and choose Delete account. Logging out or uninstalling the app does not delete your server account. For access, correction, or deletion assistance, email support@euler-works.com.
You can revoke Google access in your Google Account’s third-party connections settings. Revoking access stops that connection but does not itself delete previously saved TrackYourBite data. You can control camera, photo access, and notifications through your device settings. Manage or cancel an Apple subscription in your Apple subscription settings; deleting a TrackYourBite account does not itself cancel that subscription.
7. Children’s privacy
TrackYourBite is not intended for children under 13. We do not knowingly collect personal information from children under 13. Contact us if you believe a child has provided personal information so we can investigate and remove it.
8. Changes and contact
We will publish updates on this page and revise the date above. For privacy questions or requests, contact EulerWorks LLC at support@euler-works.com.
