Privacy Policy
Last updated: April 11, 2026
Starva ("we", "our", or "the app") is developed and operated by Honest Dev LLC. We are committed to protecting your privacy. This policy explains what data we collect, how we use it, and your rights.
1. Information We Collect
1.1 Account Information
If you sign in with Apple, we receive your name and email address (or Apple's private relay address). This is stored locally on your device and is used solely to identify your account.
1.2 Birthday & Zodiac Data
When you set up Starva, you provide your birthday and zodiac sign preferences. This data is stored locally on your device and is used to personalize your horoscopes and zodiac profile.
1.3 AI-Generated Content
We use Anthropic's Claude API to generate personalized horoscopes. Your zodiac sign and birth details are sent to Anthropic's API to generate content. No personal health data is shared. Anthropic processes this data according to their privacy policy and does not use API inputs to train their models.
1.4 Usage Data
Your horoscope history, achievement badges, streaks, and compatibility readings are stored locally on your device only. This data is never transmitted to any server.
1.5 User Preferences
Your app preferences (notification settings, display preferences) are stored locally on your device using standard iOS storage.
2. How We Use Your Data
- Horoscope generation: To generate personalized horoscopes tailored to your zodiac sign via the Anthropic Claude API.

If you delete the app, all locally stored data will be permanently deleted.
