Why your subscription matters

Snowfield is built by one person. Here is what your payment actually does.

It keeps the builder afloat

There is no company and no investor behind Snowfield. Subscriptions are the developer's income, and that income is what makes it possible to keep building.

It covers the running costs

Servers, storage and AI model calls are paid every month before anything else. Your subscription keeps the infrastructure up and funds the next release.

It says the work is worth it

Each subscription is a sign that Snowfield genuinely helps someone study. That recognition is what keeps development going, month after month.

It gives you your time back

Snowfield schedules review at the moments you are about to forget, so you remember more with fewer hours of grinding. Learn faster, retain longer, and spend the time you save on better things.

Payment region

The global region pays by card via Creem. Switch to China to pay with Alipay / WeChat.

Creem also supports Alipay: at the Creem checkout, set your country/region to China and Alipay appears as a payment method.

All prices shown in USD; taxes are calculated at checkout. Payments are processed by Creem (card).

Refund policy

Every paid plan is covered by our 7-day no-questions-asked money-back guarantee. If Snowfield isn't right for you, email us within 7 days of your first payment and we'll refund you in full.
