This Privacy Policy explains how the FitLess app ("FitLess", "we", "us", or "our") collects, uses, stores, and shares your information when you use our iOS application. By using FitLess, you agree to the practices described below.

1. Who We Are

FitLess is a calorie and nutrition tracking application. If you have any questions about this policy or your data, contact us at mdemir85@icloud.com.

2. Information We Collect

2.1 Account & Device Identifiers

When you first open FitLess, the app generates a random, anonymous account identifier (a UUID) that is stored securely on your device (in the iOS Keychain). We do not require your name or email address to use the app. This identifier is used to associate your data with your account on our servers and with the service providers listed in Section 5. We also process a push-notification token (device identifier) if you enable notifications.

2.2 Health & Fitness Data

To provide the core functionality of the app, you may enter and we store:

• Body weight logs (value, unit, date, optional notes);

• Food and meal entries (food names, calories, carbohydrates, protein, fat, serving size, brand);

• Activity / exercise entries (calories burned, notes);

• Nutrition goals and profile details you provide, such as daily calorie target, target weight, height, gender, and date of birth.

FitLess does not read from or write to Apple HealthKit.

2.3 User Content (Photos, Voice, Text)

• Food photos: If you photograph a meal or import an image, the photo is uploaded to our servers and sent to a third-party AI provider to estimate its nutritional content (see Section 5).

• Voice recordings: If you describe a meal by voice, the audio is processed for speech-to-text. Recognition may occur on your device and/or via a third-party transcription service; the resulting text transcript may be stored.

• Text you type: Food names, descriptions, and notes you enter.

2.4 Purchase Data

We offer optional auto-renewing subscriptions. Purchases are processed by Apple. We and our subscription provider (RevenueCat) receive your subscription status, entitlement, and transaction identifiers to grant premium features. We never receive your full payment card details.

2.5 Usage & Diagnostic Data

We collect product-interaction events (for example, screens viewed, paywall views, feature usage, and whether a scan succeeded or failed), language preference, and diagnostic information such as error messages, performance timings, and basic device/OS information. This helps us operate, secure, and improve the app.

3. How We Use Your Information

• To provide and operate the app's core features (logging meals, weight, and activity; AI-based nutrition estimation);

• To sync your data across your own devices via Apple iCloud (CloudKit private database);

• To process subscriptions and manage premium access and usage quotas;

• To send push notifications and reminders you have enabled;

• To analyze usage, diagnose problems, and improve the app;

• To comply with legal obligations.

4. AI Processing

Food photos and meal descriptions are sent to third-party artificial-intelligence providers (which may include OpenAI, Google Gemini, Groq, and Mistral) solely to estimate nutritional values and transcribe audio. These providers process the content on our behalf to return a result. We do not use this content for advertising.

5. Service Providers We Share Data With

We share limited data with the following processors strictly to operate the app:

• Apple — iCloud/CloudKit storage and in-app purchases.

• RevenueCat — subscription and purchase management.

• OneSignal — push notification delivery (device token).

• Google Firebase Analytics — anonymous usage analytics.

• AI providers (OpenAI, Google Gemini, Groq, Mistral) — nutrition estimation and audio transcription.

• Our hosting/backend infrastructure — to store and process your entries.

We do not sell your personal data, and we do not use your data to track you across other companies' apps or websites for advertising. FitLess does not request the App Tracking Transparency permission and does not collect the advertising identifier (IDFA).

6. Data Storage & Retention

Your entries are stored on our servers and synced to your private iCloud account. We retain your data for as long as you use the app or until you request deletion. Uploaded food images and records are kept to provide history and statistics within the app.

7. Data Security

Your account identifier is stored in the iOS Keychain, and data is transmitted over encrypted (HTTPS) connections. While no method of transmission or storage is completely secure, we take reasonable measures to protect your information.

8. Your Rights

You may request access to, correction of, or deletion of your data, including your account and associated records, by contacting us at mdemir85@icloud.com. You can also delete locally stored data and your iCloud data from your device and Apple ID settings.

9. Children's Privacy

FitLess is not directed to children under the age required by the laws of your country. We do not knowingly collect personal data from children. If you believe a child has provided us data, contact us and we will delete it.

10. International Transfers

Your data may be processed in countries other than your own, including by the service providers listed above. We rely on appropriate safeguards for such transfers.

11. Changes to This Policy

We may update this Privacy Policy from time to time. We will revise the "Last updated" date above, and significant changes may be communicated within the app.
