Promise
Review first

No vague “AI deletes your inbox” claim. Show sender groups and reasons before the user approves cleanup.

Boundary
Archive + label

Cleanup removes INBOX and applies a PurgeBox label. It does not permanently delete messages by default.

Activation
No accounts

Google identity + Stripe purchase entitlement unlocks the app. No username/password dashboard.

Why this exists

People want the backlog gone. They do not want another cloud inbox cleaner reading everything.

Review recurring senders

PurgeBox clusters repeat senders by volume, recency, and safety signals so you can see the backlog before anything changes.

Local-first by default

Gmail-derived scan data, tokens, sender maps, and cleanup receipts stay on your device. The Worker only sees payment entitlement and Google identity proof.

Pay once to unlock

PurgeBox is wired as a $9.99 one-time purchase. Stripe confirms payment, then Google identity unlocks the desktop app through a signed local entitlement token.

Payment + activation

One-time purchase. Google identity entitlement. Thin server only where payment matters.

No username/password accounts and no SaaS dashboard. Stripe proves purchase, Google proves identity, and the desktop app keeps Gmail data local.

01

Stripe Checkout

Customer buys the one-time $9.99 PurgeBox activation through Kryden's shared Stripe account.

02

Webhook entitlement

Stripe webhook verifies payment and records only the entitlement/payment row in D1.

03

Google identity

The app sends an OpenID identity proof only — never Gmail access or refresh tokens — so the Worker can match the paid email.

04

Signed token

The Worker returns a signed local entitlement token. The app verifies it locally and periodically re-checks revocation/refund status.

How it launches

Built around the real cleanup flow, not unsubscribe theater.

The MVP target is Gmail modify access for reviewed archive/label cleanup. Metadata-only scans are dev/testing; the product promise is safely changing the backlog with user approval.

01

Pay once or join early access

Buy the $9.99 activation through Stripe, or join the PurgeBox list for launch updates.

02

Connect Gmail locally

Use Google OAuth in the system browser. Gmail tokens stay in OS-protected local storage; the Worker never receives Gmail tokens or mailbox data.

03

Review, archive, receipt

Select sender groups, apply a PurgeBox label, archive by removing INBOX, and keep a local receipt with undo instructions.

Pricing

$9.99 one-time activation.

The first paid promise is a focused cleanup session, not a subscription. Ongoing hygiene can come later only if users ask for recurring scans or multi-account workflows.

FAQ

The trust questions up front.

No. The MVP is archive + label only. Cleanup is reviewed by you, reversible, and never permanently deletes Gmail by default.
The production cleanup flow is designed around gmail.modify so PurgeBox can apply labels and remove INBOX from selected messages to archive them. It avoids the broad mail.google.com scope, gmail.send, and permanent delete behavior.
The account model is Google identity + Stripe purchase entitlement. Stripe confirms the $9.99 payment, the Worker stores an entitlement in D1, the app proves Google identity, and the Worker returns a signed local entitlement token.
Only entitlement/payment records: email, optional Google subject binding, Stripe session/payment IDs, status, and event IDs for idempotency. It does not store Gmail tokens, sender maps, subject lines, message IDs, receipts, or mailbox analytics.
Gmail OAuth tokens and Gmail-derived data stay local to the desktop app. PurgeBox asks for Gmail access only to find recurring clutter and, with your approval, archive or label selected messages. It does not need your Gmail password or upload your inbox to Kryden servers.
