Paid app suddenly stops: the thirty-day subscription expiry

Why this happens

Because purchase through POST /api/apps/purchase with an idempotency key creates a fixed-term subscription, and access to the gated path is withdrawn when it lapses.

What Vareons does about it

The installed app card shows a localized Expires on date, the user profile refreshes after purchase, and the buy-and-activate button reactivates for a fresh thirty days.

• apps.marketplace.supported — Apps marketplace (install/open/uninstall): Available
• apps.finance.supported — Accounting (Finance) app: Available

Limitations

No automatic renewal is advertised; tracking it is on the merchant. Expiry disables access but does not erase the app's past data.
