How can PhoneVault actually delete contacts from other people's phones without accessing their devices?

PhoneVault can't directly access other devices, so it works through automated outreach and social pressure. The service identifies likely contact holders through social media analysis and email history, then sends professional deletion requests via SMS, email, or push notifications through companion apps. Success depends on voluntary compliance, but the service provides templates, follow-up systems, and escalation options to maximize effectiveness.

What's the legal liability if deletion requests are seen as harassment?

The key is professional, legally compliant request templates that clearly identify the service and provide easy opt-out mechanisms. PhoneVault should include legal disclaimers, limit request frequency, and provide harassment prevention features like blocking repeat requests to the same contact. Working with privacy lawyers to develop template language and maintaining clear audit trails helps minimize legal risk.

How do you verify that contacts were actually deleted?

Verification is challenging without device access. PhoneVault relies on delivery confirmations for requests, follow-up surveys asking recipients to confirm deletion, and companion app users who can anonymously report contact list changes. Perfect verification isn't possible, but transparency about limitations and focusing on request delivery metrics builds realistic user expectations.

What tech stack is needed to build the contact discovery system?

Core backend in Node.js or Python with PostgreSQL for data storage. Social media APIs (Twitter, LinkedIn, Facebook) for connection analysis. Email service integration (Gmail, Outlook APIs) for recipient discovery. React Native for companion apps. Third-party services like Clearbit or FullContact for professional contact enhancement. Redis for caching social graph data and request queues.

How do you price this without knowing actual deletion success rates?

Focus pricing on the service delivery rather than guaranteed outcomes. Position as 'professional deletion request service' not 'guaranteed contact removal.' Offer success rate transparency and partial refunds for failed delivery attempts. The premium tiers emphasize better discovery tools and professional templates rather than deletion guarantees. Enterprise tier includes manual verification attempts and legal documentation.
