Find forgotten subscriptions without bank login
Problem
People know they're leaking money on forgotten subscriptions, but every tool that finds them (Rocket Money, Mint-style apps) requires handing over bank credentials via Plaid, which many privacy-conscious users refuse to do. The r/SomebodyMakeThis poster explicitly wishes for a way to find forgotten recurring charges without giving Plaid their bank login.
Opportunity
A privacy-first subscription tracker that works from forwarded/email receipt parsing or user-imported bank statement PDFs/CSVs (no credential sharing), detects recurring charges, and sends cancellation reminders before renewals.
Market analysis
The pain is real, but this niche is more crowded than the Reddit poster thinks: several small apps (ManageSubs, SubBuddy, Subnesio) already market themselves as the no-Plaid Rocket Money alternative, mostly via manual entry. The open wedge is automatic detection from imported statements and email receipts instead of manual logging, but multi-bank statement parsing is exactly the long-tail grind where solo projects stall.
Market · Privacy-conscious consumers leaking money on forgotten subscriptions; the complaint recurs on Reddit and multiple indie apps are actively marketing against it.
Pricing · Manual-entry trackers ship freemium on app stores with low Pro tiers; comparables cluster around free-with-premium or a few dollars per month against Rocket Money's freemium model.
Pros
- + Recurring, universally-felt pain with a clear willingness to pay.
- + No Plaid licensing costs or credential liability — a genuine regulatory and trust advantage.
- + Email forwarding is a low-friction import channel users already understand.
Cons
- − Several privacy-first trackers already exist and compete on this exact positioning.
- − Bank statement PDF/CSV parsing across hundreds of formats is an endless long tail.
- − Retention is structurally weak: once the subs are cancelled, the app's job is done.

The existing no-bank trackers all make the same trade: they ask the user to do the detection work manually, which preserves privacy but quietly breaks the core promise — the user wanted to discover charges they forgot about, and manual entry can only track what they already remember. Statement parsing is the honest fix, but here the failure mode flips: once the app auto-detects recurring charges, users mentally upgrade it to “Rocket Money without the login” and expect auto-cancellation too, which is a much heavier product. The most defensible solo scope is narrow and boring: perfect PDF/CSV import for the top 20 banks, renewal reminders that actually arrive on time, and a one-page export — then charge once, because a subscription-tracker subscription that users forget to cancel is a joke the internet will make for you.
