Privacy Policy

Summary

• No account, sign-in, name, email or phone number is needed to use Protein Tracker.
• When you scan a meal or label, the photo or the description you typed is sent over HTTPS to our analysis server, which passes it to OpenAI for the estimate. Our server does not save your photos or descriptions.
• Barcode lookups are forwarded by our server to the public Open Food Facts and USDA FoodData Central databases. Only the barcode is sent.
• Photos are of food; the app does not use them to identify people.
• Your food log, goals and settings are stored only on your phone.
• Protein Tracker has no advertising, no analytics, no crash-reporting service and no cross-app tracking. It does not read the advertising ID.
• The optional Protein Tracker Pro subscription is sold through Google Play or the App Store and validated by RevenueCat, which processes an anonymous app user ID and your purchase history.
• We do not sell personal information and do not share it for advertising.

Scanning food and reading labels

You take a photo with the camera or choose one with your phone’s photo picker, or type a description. The app sends that photo or text, the kind of scan and your language to our analysis server together with a random device ID created on your phone and kept in its encrypted storage, which is used only to apply fair-use limits. If you have Protein Tracker Pro, the request also carries the anonymous RevenueCat app user ID so the server can confirm your subscription with RevenueCat. The server forwards the photo or text to OpenAI’s API, which returns the food items and nutrition estimate. Our server does not save your photos, descriptions or results and does not log their content. OpenAI processes the request as our service provider under its API terms. OpenAI states that data sent to its API is not used to train its models by default and may be kept for up to 30 days to detect abuse.

When you scan a barcode, the app sends only the barcode and your device ID to our server, which looks the product up in Open Food Facts and the USDA FoodData Central databases. No image is involved.

Nutrition figures are estimates for general information and are not medical or dietary advice.

Information stored on your device

Protein Tracker keeps the following only in the app’s private storage on your phone:

• Your food log with the items, amounts and estimates you saved, and your daily goals.
• Your settings, a random device ID used for fair-use limits (in the phone’s encrypted storage), and a record of rating requests.

Protein Tracker does not upload this information to AppsOverflow LLC. If you have turned on Android’s own device backup, Android may include the app’s saved data in your personal backup to your Google account under Google’s terms; we cannot access that backup.

Protein Tracker Pro subscriptions (Google Play, the App Store and RevenueCat)

Protein Tracker Pro is an optional subscription sold through Google Play Billing on Android and through the Apple App Store on iPhone. Google or Apple handles the payment; we never receive your card or payment details. Purchases are validated, restored and kept up to date by RevenueCat, Inc., our subscription service provider.

When the app starts, it contacts RevenueCat over HTTPS to check whether you have Pro and to load the prices the store shows, even if you never buy anything. For this, RevenueCat processes an anonymous app user ID created by the app (not linked to your name or email), your purchase history for Protein Tracker (products, store purchase tokens and order details, purchase and renewal dates, subscription status), and technical information needed to answer the request, such as app version, operating-system version, store country, currency and language, and the IP address your connection uses. Protein Tracker does not send RevenueCat your food log, photos or descriptions, your advertising ID or any contact details.

We use this information only to provide and restore your subscription, prevent fraud and see how subscriptions perform. RevenueCat processes it on our behalf as a service provider. You can manage or cancel your subscription in the Google Play Store app (Payments & subscriptions) or in your Apple ID settings (Subscriptions); uninstalling Protein Tracker does not cancel it.

Rating requests and support

Protein Tracker may occasionally ask you to rate it using the store’s own review screen (Google Play on Android, the App Store on iPhone). The store handles that screen; the app does not learn whether or how you rated it. If you email us, we receive your email address and whatever you choose to include, and we use it only to reply and resolve your request.

Permissions

Protein Tracker uses the camera only when you scan food, a label or a barcode, access to the photos you choose, Internet and network-state access to reach our server, RevenueCat and the store, vibration for haptic feedback, and Google Play’s billing permission for Protein Tracker Pro. It does not ask for location, microphone or contacts.

Sharing

We do not sell, rent or trade personal information, and we do not share it for advertising. Information is shared only with our analysis server and OpenAI (only the photo or description you scan), Open Food Facts and the USDA FoodData Central database (barcodes only), Google or Apple (store purchases and review screens) and RevenueCat to provide the functions described above, with anyone you choose to share your own files or results with, or when required by law.

Retention and deletion

Your food log and settings stay on your phone until you delete them in the app, clear Protein Tracker’s storage in your phone settings, or uninstall the app. Our server keeps no copy of your scans; OpenAI may keep request data for up to 30 days for abuse monitoring, as described above. Google, Apple and RevenueCat keep purchase records for as long as needed to provide and restore purchases and to meet accounting, tax and legal obligations. To ask us to delete RevenueCat records linked to your Protein Tracker purchases, email support@appsoverflow.com with your Google Play order number (GPA.…) or Apple receipt; we will tell you what can be removed and what must be retained by law. There is no Protein Tracker account to close.

Children

Protein Tracker is a general-audience app and is not directed to children under 13. It does not knowingly collect personal information from children. If you believe a child has provided personal information through Protein Tracker’s purchase services, contact us and we will delete it where we can.

Your rights

Depending on where you live (for example under the GDPR in the EU/UK or the CCPA in California), you may have rights to access, correct, delete or receive a copy of personal information, and to object to or restrict its processing. Because Protein Tracker stores your content only on your device, most of these rights can be exercised directly in the app or by uninstalling it. For anything held by RevenueCat or OpenAI on our behalf, email support@appsoverflow.com. You may also complain to your local data protection authority.

Security and international processing

Network traffic from Protein Tracker to RevenueCat, our analysis server, OpenAI and the food databases uses HTTPS. No method of storage or transmission is completely secure, so please keep your phone protected with a screen lock. Google, Apple, RevenueCat, OpenAI, Open Food Facts and the USDA may process information in the United States and other countries under their own safeguards and policies.

Changes to this policy

We may update this policy if Protein Tracker’s features or data practices change. The “Last updated” date above shows the current version.
