SubNuke

SubNuke is a zero-knowledge subscription and expense tracker that automatically discovers recurring charges, trial deadlines, and hidden SaaS spend without ever requiring access to your bank account through Plaid. Why we built it (No Plaid / Zero-Knowledge): Traditional subscription trackers demand full read access to your checking account, transaction history, and bank login credentials. SubNuke takes a 100% privacy-first approach: it connects read-only through standard Google and Outlook OAuth (gmail.readonly / mail.read) to scan your inbox specifically for receipt confirmations, invoices, and upcoming renewal notices. We never ask for bank credentials or credit card numbers. Key Features: • Read-Only Email Discovery: Detects active software trials, recurring SaaS bills, and forgotten memberships in seconds. • 3-Day Early Warning Alerts: Get notified 3 days before a free trial renews or an annual charge hits your card so you have time to cancel. • 500+ Verified Cancellation Playbooks: Stop navigating 5-step retention mazes. SubNuke gives you exact 1-click direct portal links and fee-avoidance instructions for over 500 SaaS tools and subscriptions. • Ephemeral Processing: Raw emails are processed in memory and immediately discarded; only extracted billing dates and amounts are stored.
