This Privacy Policy describes how Ertuğrul Sarı ("we," "our," or "us") collects, uses, and handles information when you use AI Calorie Tracker: Food Log (the "App"). By downloading, installing, or using the App, you acknowledge that you have read and understood this Privacy Policy.
The App is developed and operated by Ertuğrul Sarı, an independent developer. For any privacy-related questions, contact us at estifieapps@gmail.com.
We built this App with privacy in mind. Here is the short version:
We do not have user accounts or authentication systems.
We do not collect, sell, rent, or share your personal data with advertisers or data brokers.
We do not use any third-party analytics or crash-reporting SDKs.
Your meal photos are stored only on your device and are never uploaded to any cloud.
Your nutritional and wellness data is synced privately via Apple CloudKit to your own iCloud account — we cannot access it.
AI features are processed through our own backend server and the data is not retained after your request is fulfilled.
Subscription management is handled by RevenueCat.
When you set up or use the App, you may provide profile information such as your age, biological sex, height, current weight, goal weight, activity level, and dietary preferences or notes. You may also log meals including their title, food components, macronutrients (calories, protein, carbohydrates, fat, fiber, sugar, sodium), meal type, timestamp, and an optional free-text location label. Weight check-ins, journey goals, and daily water intake are also stored. All of this data lives on your device and syncs to your personal iCloud account via Apple CloudKit — we do not have access to it.
Meal photos you take or select from your library are stored exclusively on your device. They are never synced to iCloud or any cloud storage.
When you use AI features, the App sends a randomly generated, per-installation device identifier to our backend server. This identifier is used solely to enforce fair-use rate limits. It cannot identify you personally and is not linked to any account. Your app version and language locale are also sent so we can return food names and insights in your language.
With your explicit permission, the App reads the following data from Apple Health:
Active energy burned (kilocalories per day)
Workout sessions (type, duration, calories burned)
This data is displayed inside the App for your own awareness. We do not write any data back to Apple Health, and we never send HealthKit data to our servers or any third party.
We do not collect your name, email address, phone number, or any contact information. We do not collect payment card details — all payments are processed exclusively by Apple. We do not collect precise GPS location. We do not collect advertising identifiers, behavioral analytics, or browsing history. We do not use cookies.
Your on-device and iCloud data is used solely to power your personal nutrition and wellness dashboard within the App. When you request AI-powered features, we process the relevant data as follows.
For meal photo analysis, we send the photo (resized JPEG, maximum 2048 pixels per edge) along with an optional meal type hint and your locale to our backend, which returns a breakdown of estimated calories and macronutrients. The photo is not stored after processing.
For meal insights and meal suggestions, we send your meal details, aggregated daily totals, weekly averages, dietary preferences, recent meal history, and locale to our backend. No photos are sent for these requests.
For barcode scanning and food search, only the barcode value or the food search term is sent to the Open Food Facts public database. No personal or identifying information is included.
Your anonymous device identifier is used only for rate-limiting AI requests. Your RevenueCat subscriber ID is used only to determine whether you are on a premium plan, which affects your rate limit.
Notification reminders are sent locally by your device based on the time you configure. We do not have access to your notification preferences.
The App's AI features — meal photo analysis, nutritional insights, and meal suggestions — are all processed through our own backend server. The App does not connect directly to any AI provider.
Our backend uses OpenRouter to route requests to AI models including Google Gemini and potentially other models. The data you submit (meal photos, meal details, dietary context) is processed by these services to generate a response. Once the response is returned to you, the data is discarded — our server does not maintain a database of your requests.
You should be aware that data processed through OpenRouter and Google Gemini is subject to their respective terms and privacy policies. We do not share your name, email, or any account information with these services; requests contain only the meal and nutritional context needed to answer your query.
We do not sell, trade, or rent your information to anyone. We share data only in the following circumstances.
Apple (CloudKit): Your meals, profile, weigh-ins, journeys, and workout data sync to your personal iCloud account via Apple CloudKit. This data is encrypted and controlled by Apple under your Apple ID. We have no access to it. Apple's Privacy Policy applies: https://www.apple.com/legal/privacy/
RevenueCat: RevenueCat manages your in-app subscription. It receives a pseudonymous app user ID, your purchase receipt from Apple, and your entitlement status. RevenueCat Privacy Policy: https://www.revenuecat.com/privacy
Open Food Facts: When you scan a barcode or search for food, only the barcode value or search term is sent. No personal information is included. Open Food Facts Terms: https://world.openfoodfacts.org/terms-of-use
Our AI Backend / OpenRouter / Google Gemini: Meal and nutritional context is sent as described in Section 5. No account information or directly identifying data is transmitted.
Legal requirements: We may disclose information if required by law or valid legal process, or to protect the rights, property, or safety of Ertuğrul Sarı, our users, or the public.
Meal photos are stored on your device only and are automatically deleted based on your configured retention period (default 30 days) or when you uninstall the App. Your profile, meals, journeys, and weigh-ins live in your iCloud account and persist until you delete them within the App or delete your iCloud account. Your device identifier persists in your device's local storage until you uninstall the App. Barcode lookup results are cached on your device for 7 days to reduce network requests. Subscription state is stored on RevenueCat's servers per their retention policy. Data sent to our AI backend is not retained after the response is returned.
The App is not directed to children under the age of 13, or under 16 in the European Economic Area. We do not knowingly collect personal information from children. If you believe a child has provided information through the App, please contact us at estifieapps@gmail.com and we will take appropriate steps.
Because we do not maintain a user account database, nearly all of your data resides on your device or in your own iCloud account, which you control directly.
To delete all on-device data, including meal photos and cached data, uninstall the App. To delete your synced data from iCloud, go to Settings → [Your Name] → iCloud → Manage Storage on your iPhone and remove the App's iCloud data. To manage HealthKit permissions, use the Apple Health app. To revoke camera or photo library access, go to Settings → Privacy & Security on your iPhone. To disable notifications, go to Settings → Notifications → AI Calorie Tracker.
If you are a resident of the European Economic Area, you have rights to access, correct, or erase personal data we hold, as well as rights to data portability and to object to processing. Because most data is stored on your own device or iCloud, most of these rights can be exercised directly. For any remaining requests, contact us at estifieapps@gmail.com.
If you are a California resident, you have the right to know what personal information we collect and to request its deletion. We do not sell personal information. Contact us at estifieapps@gmail.com for any requests.
All communications between the App and our backend, as well as third-party services, are protected using HTTPS/TLS encryption. However, no method of data transmission or storage is completely secure, and we cannot guarantee absolute security. We disclaim liability for any unauthorized access to data transmitted to our servers.
We may update this Privacy Policy from time to time. We will notify you of significant changes by updating the "Last Updated" date at the top of this document and, where appropriate, through a notice in the App or the App Store listing. Your continued use of the App after changes constitutes your acceptance of the updated policy.
