Privacy Policy
Effective Date: March 6, 2026 | Last Updated: May 11, 2026
dotTreeSoft ("Company," "we," "us," or "our") operates the canu AI mobile application ("App," "Service"). This Privacy Policy explains how we collect, use, store, and protect your personal information when you use our Service.
By using canu AI, you agree to the collection and use of information in accordance with this Privacy Policy.
1. Information We Collect
1.1 Account and Login Information
canu AI supports Google Sign-In, Apple Sign-In, and limited guest use through an anonymous app session. We do not provide separate email/password registration. When you sign in with a third-party provider, we receive the following information from your chosen provider:
| Provider | Information Received |
|---|---|
| Email address, display name, profile photo URL | |
| Apple | Email address (may be relay address), display name |
We do not store your social login password. Authentication is handled entirely by each provider.
If you use the App as a guest, we may create an anonymous user ID so your onboarding answers, meal records, subscription state, and app preferences can be saved. If you later sign in with Google or Apple, we may link or merge the anonymous data into your signed-in account.
For community features, your login identifier is separated from your public community identity. Posts and comments display only your community display name, handle, and profile image. Your email address is not shown in community posts, comments, or public profile surfaces.
1.2 Information You Provide During Onboarding
- Location / region (country)
- Health goals (e.g., weight loss, muscle gain)
- Physical stats (height, weight, age, gender)
- Dietary restrictions (e.g., vegetarian, gluten-free, halal)
- Current supplements
- Health focus areas
Region selection is used to personalize nutrition context, food analysis, language-related features, and default measurement units. canu AI does not require precise GPS location for these features. If your device provides an operating system locale or region setting, we may use that setting to choose defaults such as language, country context, and measurement units (for example, kg/cm/g or lb/in/oz). You may change certain preferences in the App settings where available.
1.3 Information Generated Through App Usage
- Food photos: Images you take for meal analysis (stored in our cloud storage)
- Meal analysis data: Calorie estimates, macro/micronutrient breakdowns
- Chat history: Conversations with the AI nutrition coach
- Nutrition scores and streaks: Daily tracking data
- AI-generated meal plans: Personalized meal and supplement recommendations
- Community activity: Posts, comments, likes, achievement badges, display name, handle, and profile image used in community features
1.4 Automatically Collected Information
- Device information (device model, operating system version)
- App version
- Operating system locale, region, and language settings used for localization, community language filters, and default measurement units
- IP address (masked in logs for privacy)
- Usage logs (endpoints accessed, timestamps)
