# Billing

Strumhold’s core is free: the daily practice set, drills and scoring, progress, calibration, and the export and import backup path all work with no account and no payment. A subscription adds the online layer on top.

## What the subscriptions are

- **Sync** backs your practice history up automatically and merges it across your devices. The backups and sync topic explains how it behaves.
- **Pro** includes everything Sync does and adds Diagnosis (which side of each change needs work), jamming over a band, and the whole Songbook: every song’s gaps and drills.

Subscriptions are sold in the web app at strumhold.app, not through app stores.

A subscription is yours on every device: sign in and the app unlocks.

## Managing a subscription

Managing, changing plan, or canceling also happens in the web app at strumhold.app: open Settings there and look under Account. Canceling never touches your practice history: everything stays on your device, you keep practicing, and Export keeps working.

## Subscribing

Open Settings in the web app at strumhold.app, sign in with Google under Account, pick a plan, and tap **Subscribe**. You see the price before anything is charged. Stripe handles the payment, so your receipts and card statement name Stripe.

## Changing plan or canceling

Under Account, **Manage subscription or change plan** opens your billing page at Stripe, where you can switch plans, update your card, or cancel. A plan switch shows its price before you confirm.
