Subject: about the pricing

Hey Maya — saw you uninstalled after eight months, and that the price stopped making sense for the season. Totally fair. If it helps, I'm open to working something out for the slow months — just reply here. Either way, thanks for running with us as long as you did. — [Your name]

Drafted from their plan, tenure, and stated reason — in their language.

Three things no other Shopify analytics tool ships

Every competitor shows you MRR. Crust tells you why it moved — and hands you the reply.

AI-classified churn reasons

Shopify's exit survey is mandatory now — Crust translates and classifies every answer (any language) into eight canonical reasons, split into what you can fix and what you can't. No competitor has any AI classification.

Win-back drafts, written for you

Every churned merchant gets a founder-voice recovery email drafted from their plan, tenure, lifetime spend, and stated reason. Price objection? It offers to work something out. Bug? It apologizes plainly.

Zero-config trial tracking

Built on Shopify's 2026 Partner API events — trial length, conversions, and in-trial cancels come straight from Shopify, carryover-aware. Others make you configure trial lengths by hand or guess from heuristics.

The full metrics stack

MRR movements, ARR/ARPU/LTV, NRR & GRR, retention and revenue cohorts, install→paid funnel.

Real collected revenue

CLV and payouts from actual Partner transactions — usage charges included, not dumped in 'other'.

Merchant contacts

An identify API captures owner emails the Partner API can't give anyone — and they survive token changes.

Slack alerts & digests

Uninstall alerts with reason + contact attached, and an AI weekly digest with one recommended action.

Connected in five minutes, honestly

Why “Crust”?

Your app business sits on layers you can't see. Beneath every Shopify app there's a churning mass of data — installs, uninstalls, subscriptions, trials, exit surveys — molten, moving, and mostly invisible. Parts of it, like your trial and subscription events, vanish from Shopify's feed after 30 days. The rest is scattered and unreadable.

The crust is the layer you live on — thin, solid, walkable ground formed from everything shifting underneath. Crust turns the churn below your app into ground you can stand on.

Fair questions

What do you do with my Partner token?

Read-only queries against Shopify's Partner API, encrypted at rest, never shared. You can revoke it in your Partner Dashboard at any moment. There's also a redaction API for GDPR shop/redact webhooks.

Do you do billing like Mantle did?

No — deliberately. Shopify's native App Pricing (May 2026) handles billing now. Crust is the intelligence layer on top: why merchants leave, what they're worth, and how to win them back.

I'm on Mantle. Do I need to export anything?

No. Your history lives in Shopify's Partner API, not in Mantle — Crust rebuilds years of it from a single token in about 20 minutes. The one thing worth exporting from Mantle before August 14 is merchant contact emails; we import that CSV directly.

What happens after the free-until-2027 offer?

Standard pricing ($49/mo Growth) with a heads-up well in advance. Prices at heycrust.com only ever ratchet downward — the sticker you see is the ceiling.

Your churn has reasons.
