Dear Sandbox Smart Users,

Thank you for your continued support and trust in Sandbox Smart.

To allow more users to fully enjoy Sandbox Smart’s roasting features and the experience of coffee roasting immediately after purchasing their machine, while also continuing to promote the culture of home coffee roasting, Sandbox Smart has comprehensively optimized its product and service planning.
Effective immediately, we are officially adjusting the existing VIP subscription and app service structure, while simultaneously launching the new Sandbox Smart Pro App. Through a more open and convenient approach, we hope to provide users with a more complete and enhanced experience.

To protect your rights and ensure a smooth transition, please read the following announcement carefully and complete the relevant actions as instructed.

1. Changes to the VIP Subscription Service

In line with Sandbox Smart’s overall product operation strategy adjustment, effective immediately, the VIP features that were previously available only through a paid subscription will now be provided free of charge to all users.

We hope that every user who purchases a Sandbox Smart machine can enjoy a more complete roasting experience and full access to roasting features without the burden of additional subscription fees. This change also further reflects Sandbox Smart’s brand mission of promoting the joy of coffee roasting.
