ChargeDetector is a privacy-first tool that scans your email export for forgotten subscriptions in 30 seconds. Upload an .mbox file from Gmail, Outlook, or Apple Mail, and it matches against 60+ known services across 6 languages โ entirely in your browser.
How it works: - Export your inbox as .mbox (from takeout.google.com, Outlook, or Apple Mail) - Upload the file โ supports .mbox, .json, .zip, .gz up to 500MB - In ~30 seconds, see every detected subscription with annual costs - Use direct cancellation links to cancel what you don't need
Why it's different: Unlike Rocket Money or Trim, ChargeDetector requires no account, no bank linking, and no app install. Nothing is uploaded to any server โ scans run entirely in your browser. Only email subject lines are scanned (never body content or attachments). Scan data is deleted immediately after each session.
Features: - 60+ service detection across 6 languages - Annual waste total with 5/10-year projections - Direct cancellation links for every service - Batch cancellation (open all at once) - Category breakdown (Entertainment, Productivity, Cloud, etc.) - ICS calendar reminders for monthly re-audits - PWA installable โ works offline
Pricing: - Free: 1 scan/month - Lifetime: $29 one-time (no recurring fees)
Built with Next.js 16 + TypeScript. Zero backend, zero database.

ChargeDetector's answer
Unlike Rocket Money, Truebill, or Trim, ChargeDetector doesn't require you to hand over bank credentials, link financial accounts, or install an app. You stay in control of your data. Upload an email export once, get your full subscription audit in seconds, and walk away. No recurring fees, no upselling, no data mining. Lifetime access is $29 โ most competitors charge that every month for premium features.
ChargeDetector's answer
Privacy-conscious professionals who want to audit recurring expenses without giving third parties access to their financial data. The typical user has 3-5 forgotten subscriptions draining $400-$800/year and wants a one-time check rather than ongoing monitoring. Users span freelancers, remote workers, and anyone who switched jobs and lost track of software subscriptions.
ChargeDetector's answer
I discovered I'd been paying for Adobe Creative Cloud for 18 months after leaving a previous job โ $1,079 I'll never get back. Manually searching 2 years of Gmail receipts was painful and took over an hour. I built ChargeDetector to make this process take 30 seconds instead of an afternoon. The goal: help people find and cancel wasted subscriptions without compromising their privacy.
