How it works

I

Connect read-only

Paste a restricted Stripe key with read access only. 30 seconds, revocable any time — we refuse full-access keys by design.

II

We scan daily

Six detectors sweep your account every day: failed payments, dying cards, cancellations, downgrades, forgotten coupons, churn risks.

III

One email, Monday

How much went at risk, what recovered, and a pre-written recovery email for each finding — you just hit send.

What we catch

Every finding ships with a pre-written recovery email tuned to the exact decline code — one click opens it in your outbox. We never contact your customers.

Failed payments

Every failed invoice, whether Stripe is still retrying, and what to do next.

Expiring cards

Cards expiring within 30 days that are attached to active subscriptions.

Scheduled cancellations

Customers who already hit cancel — catch them before the period ends.

Silent downgrades

Plan value drops in the last 7 days. Downgrades often precede churn.

Forever coupons

Permanent discounts quietly eating your MRR, forever.

Involuntary churn

Subscriptions in past-due limbo, about to churn from payment failures.

Frequently asked questions

Is my Stripe data safe?
We only accept read-only restricted keys — full-access live keys are refused. Your key is AES-256-GCM encrypted at rest, and we store Stripe ids, amounts and status flags only: never card data, never addresses.
Do you email my customers?
Never. We write the recovery email for you, tuned to the exact decline code, and open it in your own mail client. You stay in control of the send button.
What does it cost me if it finds nothing?
The weekly report tells you either way — a clean report is worth knowing too. And with roughly 9% of subscription payments failing each month, most accounts have something to recover.
Can I cancel any time?
Yes — from the Stripe-hosted billing portal, in two clicks. The 14-day trial won't charge your card until day 15.
