Privacy policy

1. Introduction

Welcome to SweetZero. We are committed to protecting your privacy and ensuring the security of your personal information. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application and services.

By using SweetZero, you agree to the collection and use of information in accordance with this policy. If you do not agree with our policies and practices, please do not use our services.

2. Information We Collect

2.1 Personal Information

We may collect personal information that you provide directly to us, including:

• Name and email address when you create an account
• Profile information and preferences
• User-generated content, including posts and comments
• Communication data when you contact us for support

2.2 Health and Activity Data

To provide our core services, we collect health-related information:

• Streak tracking data (days, hours, minutes since last sugar consumption)
• Challenge participation and completion data
• Milestone achievements and badges earned
• Daily check-in information
• Anonymous mode preferences

2.3 Automatically Collected Information

We automatically collect certain information when you use our app:

• Device information (model, operating system, unique device identifiers)
• Usage data (features accessed, time spent in app, interaction patterns)
• Log data (IP address, access times, app crashes)
• Location data (if you grant permission, used for regional features)

2.4 AI-Powered Features

Some features use artificial intelligence from third-party providers. We currently reach these models through OpenRouter, which routes requests to AI models such as Anthropic's Claude.

• AI food scanner: the photo, barcode and label text you scan are sent to the AI provider to detect sugar and the names it hides behind.
• AI insights: to write daily plans, weekly reports and pattern alerts, a summary of your streak, check-in, mood and craving data is sent to the AI provider.
• Label detective: your quiz answers are stored with your account to keep your quiz streak, points and field guide.

We send only what each feature needs and never include your name or email address. The provider uses this data to return a result to us.

3. How We Use Your Information

We use the collected information for the following purposes:

• Service Delivery: To provide, maintain, and improve our services, including streak tracking, challenges, and community features
• Personalization: To customize your experience and provide relevant content, tips, and recommendations
• Communication: To send you updates, notifications, and respond to your inquiries
• Analytics: To analyze usage patterns and improve app performance and user experience
• Advertising Measurement: With your permission, to learn which of our ads led people to install SweetZero, as described in section 4.1
• Safety and Security: To detect, prevent, and address technical issues, fraud, or abuse
• Legal Compliance: To comply with applicable laws, regulations, and legal processes

4. Data Sharing and Disclosure

We respect your privacy and do not sell your personal information. We may share your information only in the following circumstances:

• With Your Consent: When you explicitly agree to share information, such as participating in public challenges
• Service Providers: With trusted third-party service providers who assist us in operating our app (hosting, analytics, customer support), subject to confidentiality agreements
• AI Providers: With the AI provider that powers the food scanner and AI insights, only as described in section 2.4
• Anonymous/Aggregated Data: We may share anonymized, aggregated data that cannot identify you individually for research or analytics purposes
• Legal Requirements: When required by law, court order, or government regulation
• Business Transfers: In connection with a merger, acquisition, or sale of assets, with notice to users

4.1 Advertising Measurement (Meta)

We advertise SweetZero on Meta (Facebook and Instagram). To know which ads work, the app uses the Meta SDK. Meta receives:

• That the app was installed and opened, and when you create an account
• That you started a trial or subscribed in the App Store or Google Play, and the price
• Technical details such as device model, OS version, IP address and a Meta app-scoped identifier
• Your device's advertising identifier (IDFA on iPhone, Advertising ID on Android), only if you allow it

Meta never receives your check-ins, moods, cravings, notes, food scans, health data or community posts. On iPhone we only use the advertising identifier if you choose "Allow" when iOS asks whether SweetZero may track you; on Android we ask in the app first. You can change this any time in the app under Settings › Privacy › Ads measurement, or in your iPhone's Settings › Privacy & Security › Tracking. Meta's use of this information is described in the Meta Privacy Policy.

5. Data Security

We implement industry-standard security measures to protect your information:

• Encryption of data in transit using SSL/TLS
• Secure storage of data with encryption at rest
• Regular security assessments and updates
• Access controls limiting employee access to personal data
• Secure authentication and authorization mechanisms

However, no method of transmission over the internet or electronic storage is 100% secure. While we strive to protect your data, we cannot guarantee absolute security.

6. Your Rights and Choices

You have the following rights regarding your data:

• Access: Request access to your personal information
• Correction: Update or correct inaccurate information
• Deletion: Request deletion of your account and associated data
• Data Portability: Request a copy of your data in a portable format
• Opt-Out: Opt out of certain data collection or communications
• Ads Measurement: Turn off advertising measurement at any time, as described in section 4.1
• Anonymous Mode: Use anonymous mode to participate in the community without revealing your identity

To exercise these rights, please contact us at hey@fronttribe.com.

7. Children's Privacy

SweetZero is not intended for children under the age of 13. We do not knowingly collect personal information from children under 13. If you believe we have collected information from a child under 13, please contact us immediately, and we will take steps to delete such information.

8. International Data Transfers

Your information may be transferred to and processed in countries other than your country of residence. These countries may have data protection laws that differ from those in your country. We take appropriate measures to ensure your data is protected in accordance with this Privacy Policy.
