Terms

These are the terms for using Suikō, at suiko.ink and in the iOS app. Using it means you agree to them.

What Suikō is

A place to write one page of Japanese a day and have it read by an editor that marks what’s wrong and leaves the rewriting to you. The marks come from an AI model. They’re usually right and sometimes wrong, and they’re feedback on your writing, not a qualification, a grade, or advice for anything outside it.

Your account

You need to be at least 13 to have one. Keep your password to yourself; what happens under your account is yours. You can change your address and password in Settings, and delete the account there too.

Your writing

It’s yours. We don’t claim any rights in what you write, and we only use it to do what you asked: store it, show it back to you, and send it for a read when you press the button. The privacy page says where it goes and what’s kept. Don’t write anything unlawful, and don’t use the service to harm anyone.

Paying

Writing is free. The editor’s reads are part of the paid plan, which begins with a 7-day free trial — on the web with no payment details until it ends, and in the iOS app through the App Store with your Apple ID’s payment method — and then costs the price shown on the pricing page per month. On the web you pay through Stripe and can cancel any time from Settings; the plan runs to the end of the period you’ve paid for. In the iOS app you pay through Apple, and cancel through your Apple subscriptions. Each page can be read a limited number of times; the limit is on the pricing page.

Ending things

You can stop at any time by deleting your account. We can close an account that’s breaking these terms or being used to attack the service. If we ever have to shut the service down, we’ll give notice and time to take your writing out.

What we promise, and what we can’t

We work to keep the service up and your writing safe, and we back it up. But it’s provided as it is: we can’t promise it’ll never be down, that a mark will never be wrong, or that a page can always be recovered, and we’re not liable for losses beyond what you’ve paid us in the last twelve months, to the extent the law allows.

Changes

If these terms change in a way that matters, the date at the top moves and we’ll tell you before it takes effect. Questions go to the address on the support page.
