We have not started billing yet
Serving static files costs next to nothing anywhere. The ₩4,900 is for what stands on top of it — members, boards, forms and analytics. Nothing is billed while you build and refine; it starts once a project actually goes live.
The monthly rate includes VAT (10%); usage charges are separate
Base
₩4,900/ per project, monthly

What it costs to keep one live project standing

When one of the three below switches on, that month is billed prorated. Nothing is billed before then.
Monthly active members means signed-up members who logged in or were active that month. Visitors who only browse are not counted. So your invoice stays the same even when visits multiply.
Evaluation for all three triggers is still being built, and the visit threshold has no figure yet. We announce it before it applies, once that work is done.
All three come with the monthly rate. There is nothing extra to switch on, and your invoice reads the same whether you use them or not.
Products · orders · approval · checkout · refunds. It does not have to be a store — deposits, class fees, dues, a single piece of work, donations
Slots · confirmation · double-booking prevention · cancellation · notifications
Boards by member tier · visibility per post · members-only areas
'Not yet open' describes the feature, not a price. It is covered by the monthly rate, but the wiring is not finished, so please do not start trading on it yet. This page changes first when it opens.
Your monthly rate already carries the amounts below. Traffic is never charged, however much of it arrives. Storage comes with an included amount, and we have not set a price for going past it, so nothing beyond it is billed. If we ever set one, you get 60 days of notice before it starts.
| Item | Included | Past that |
|---|---|---|
| Traffic | Unlimited |
The monthly rate includes VAT (10%); usage charges are separate. Listed prices are our own confirmed rates, and any claim carrying a number keeps its evidence and measurement records on file before publication (per Article 5 of the Fair Labeling and Advertising Act). Billing is monthly in arrears and prorated, with the monthly rate and the actual-use items (messaging, AI tokens) charged together in one payment. Amounts paid by card are evidenced by the card sales slip. Storage past the included amount is not billed — we have not set a rate for it, and you get 60 days of notice before any rate takes effect. Items marked 'not yet open' are covered by the monthly rate, but their wiring is not finished, so please do not start trading on them yet.
| Not charged |
| File storage | 10 GiB | Rate not set — 60 days of notice first |

| Messaging (KakaoTalk alerts · SMS · email) | None | Billed on what you sent, monthly in arrears |
Per site · per month. Nothing is topped up in advance. Messaging is billed on what you actually sent, and it lands on the next invoice bundled together with your monthly rate.
How many times your own AI changed the site. We are still settling how to count it, so nothing is billed for it yet.

KakaoTalk alerts, SMS, and email land on next month's invoice by how many you sent. Nothing is topped up in advance, and it arrives on the same invoice as your monthly rate.
