1. Legal Compliance
Laws like GDPR (Europe), CCPA (California), and LGPD (Brazil) require you to disclose how you handle user data. Fines for non-compliance can be significant.
2. Third-Party Requirements
Tools like Google Analytics, Facebook Ads, and Apple's App Store require you to have a privacy policy to use their services.
3. Building Trust
Transparency is the new currency. Users are more likely to share their email or buy from you if they know their data is safe.
