No — the plugin keeps working and you keep all your data; you only lose automatic updates and support until you renew.
When your license expires or is deactivated:
- Your coupons and settings stay intact. Nothing is deleted and no features are switched off.
- Coupon Creator Pro keeps running. Existing coupons continue to display and print exactly as before.
- You stop receiving automatic updates. New versions and fixes will not download until the license is active again.
- Priority support pauses. Ticket support requires an active license (see What support you can expect).
To restore updates and support, renew your license — see Renew your license. Because you keep running an older version while lapsed, it is a good idea to renew before a major WordPress upgrade so you can get any compatibility fixes. For what an active subscription covers, see What the license includes.
