Only the features you need to run your classroom.

No. For students, sign-up, searching for classrooms, and booking are all free. You only pay the lesson fees or monthly tuition set by each classroom — the booking/payment fee (8%) is deducted from the classroom's payout, so nothing is added on top for students.

Yes. Premium isn't just for adding more classrooms — it makes student management, messaging, monthly billing, attendance, and analytics easier to run together. It tends to pay for itself once you pass around 10 students or start sending more cancellation and schedule-change notices.

Yes, you can upgrade from the dashboard whenever you like, choosing either monthly or annual billing. As soon as payment is complete, Premium features are available across all of your classrooms.

The price and billing cycle differ. Monthly billing charges JPY 3,980 every month; annual billing charges JPY 39,800 once a year. Annual works out to about JPY 3,317 per month, saving you JPY 7,960 a year (roughly 2 months' worth). Either way, the features and limits are the same.

Yes. After subscribing, you can switch between monthly and annual from "Check billing info" → "Billing dashboard" in the management screen. The new price (JPY 39,800 for annual) is charged on the day you switch, and a new billing period starts that day. The unused part of the period you already paid for is not refunded, so we recommend switching just before your next renewal date.

If you cancel partway through an annual period, you can keep using Premium features until the end of the current billing period (the next renewal date). We don't offer prorated refunds for early cancellation. You'll automatically move to the Free plan once the period ends.

The limit is counted across every classroom you run — not per classroom — and includes every student whose roster status is "enrolled". A student becomes enrolled by being added by hand, imported from CSV, accepting an invitation, buying a lesson pack, or joining a monthly plan; it is not limited to monthly-plan members. Users who only book a visit, a trial, or a single session are not counted. All 250 can sit in a single classroom, or be spread across up to 5. Setting a student to inactive frees up their slot.

It's charged once a booking is confirmed and online payment is complete. Monthly tuition is charged on each monthly payment, and a lesson pass is charged when it's purchased — there's no extra fee when a student uses a session from the pass. For a fully refunded cancellation, the fee is refunded in full too. If the cancellation policy only allows a partial refund, the fee is charged in proportion to the amount the classroom receives.

No. Bookings and events paid on-site have a 0% fee. The 8% fee only applies to online payments (bookings, monthly tuition, and lesson pass purchases).

At Chaen, we care about making it easy for tea ceremony classrooms to join without strain. That's why listing is free, and we've set the booking/payment fee at an accessible 8%. That 8% covers helping students find you (search and your classroom page), booking management, payment processing, and automatic notifications. Platforms that also bring you students typically charge somewhere around 10–30% (based on publicly available rates as of July 2026), while booking systems that only process payments (roughly 3–5%) cover a narrower scope. The fee is a percentage of the payment amount (tax included); no additional consumption tax is added on top.

Payments are automatically deposited into the classroom's registered bank account via our payment processor, Stripe. Payouts arrive around day 10 of each month and cover the previous month (you can change the payout date in Stripe), and you can review upcoming and past payouts from the "Billing & payouts" tab of the owner dashboard. Chaen does not charge any separate transfer fee.

There's no free trial of the whole plan, but the analytics features come with a 14-day free preview (no payment involved — you start it from the analytics tab in your dashboard, once per owner account). The preview only unlocks the analytics and report views; it does not raise your limits on classrooms, students, or broadcasts. You can also stay on the Free plan indefinitely at no cost, and you can cancel Premium at any time at the end of a billing period, with no cancellation fee.

You'll automatically move to the Free plan at the end of your current billing period. Your listing, booking, and roster data will not be deleted. However, the Free plan can publish only one classroom, so any additional classrooms become unpublished: their students' monthly plans stop at the next billing date and any unused lesson passes are refunded (you choose which classroom to keep on the cancellation screen). If you have more than 10 enrolled students, your roster stays as it is, but you can't accept new enrollments (including monthly plans and lesson passes) until you're under 10. Premium-only analytics and the booking and monthly-fee report exports also become unavailable (roster export stays available on the Free plan).

You can publish up to 10 classroom blog posts a month on Free, and up to 30 a month on Premium (a draft counts as one post). Each post can include up to 20 photos, at up to 10MB each (JPEG, PNG, or WebP). Photos are compressed automatically when you post, so they won't slow the page down. Posts you write under your own name on the site-wide Chaen blog are limited to 7 a month regardless of plan.

We support credit card payments via our payment processor, Stripe (Visa, Mastercard, JCB, American Express, and more). On your students' card statements the payment appears as "CHAEN" (Chaen), not as your classroom's name (we also tell students this on the payment screens and in their emails).

Yes. Premium is an owner-level plan, so it applies to every classroom you operate.
