Terms

Your account

You sign in with a Google account and are responsible for what happens under it. Keep your Google account secure. You must be at least 13 years old to use Tokki.

Subscriptions

• Tokki offers a monthly plan ($15 a month) and a yearly plan ($100 a year). Prices may change; a change applies from your next billing period and we tell you before it does.
• Payments are handled by Polar, which acts as the seller of record. Taxes may be added at checkout depending on where you live.
• A subscription renews automatically until you cancel. You can cancel at any time; you keep access until the end of the period you paid for.
• You join Tokki with a Friend Pass, from a member or from Tokki. It gives 7 days free, with a $6 credit toward your first payment. You add a card when you start it. If you cancel during the 7 days, you are not charged. If you don't, the plan you chose starts on day 8 and is charged. You can claim a Friend Pass once, on your first plan, and you can't claim another later. Sending Friend Passes to others has no limit.

Refunds

• Your first payment after the free days: ask within 14 days and we refund it in full. This covers your first payment only, and it applies once per account for as long as the account exists, even if you cancel and subscribe again later.
• A yearly renewal: ask within 14 days of the renewal and we refund it in full. Polar, as the seller of record, emails you 7 days before a yearly plan renews.
• Monthly renewals are not refunded. When you cancel, you keep Tokki until the end of the month you paid for.
• Marketplace items (papers and books): before you open one, ask within 14 days and we refund it in full. Once you open it, it can't be refunded. You agree to this when you buy.
• To ask for a refund, use Send feedback in Settings or write to support@tokki.world.
• Polar, as the seller of record, may also refund a payment on its own to settle a dispute.

Credit

• When someone joins with your Friend Pass and makes their first payment, you get $3 of Tokki credit. If that payment is refunded, the credit is taken back.
• Credit pays for things you buy in Tokki. It also goes toward your subscription: up to $6 of credit is used on each monthly renewal and up to $72 on a yearly renewal, and what's left waits for the next one.
• Credit has no cash value, can't be moved to another account, and isn't refunded.

What you make

Your papers, boards, recordings, cards and posts stay yours. You give Tokki the permission it needs to store them, show them to you and to the people you share them with, and run the features you use on them (for example, checking an answer or reading a sentence aloud). This permission ends when you delete the content or your account, except for community posts as described in the Privacy Policy.

Community and marketplace

Be kind, and post only what you have the right to post. No harassment, hate, sexual or violent material, spam, or other people's personal information. We may hide or remove content that breaks these rules and suspend accounts that keep breaking them. Listings follow the Marketplace rules.

AI features

The AI tutor and automatic answer checking can be wrong. Use them as a study aid, not as an authority. Do not enter information you would not want processed by our AI provider.

Videos and other people's content

Videos play from YouTube under YouTube's terms. Subtitles and study materials built around them are for personal learning. If you own something used in Tokki and did not allow it, ask us to take it down.

Things you must not do

• Break the law, or help someone else do so, using Tokki.
• Try to get into other people's accounts or data, or around limits we put in place.
• Copy Tokki's materials in bulk, or scrape the app.
• Disrupt the service, for example by overloading it.

Ending

You can delete your account at any time in Settings. We may suspend or close an account that breaks these terms; where we can, we will tell you why first.

No warranty, limited liability

Tokki is provided as it is. We work to keep it running and your work safe, but we cannot promise it will always be available or free of errors. To the extent the law allows, our liability to you is limited to what you paid us in the 12 months before the claim.

Changes

If we change these terms in a way that matters, we will tell you in the app before it takes effect.

Contact and governing law

Tokki is operated by Donggeon Kim, 421 Jungang-daero, Jung-gu, Daegu, Republic of Korea. Write to us at support@tokki.world.

These terms are governed by the laws of the Republic of Korea. Nothing in them takes away rights you have under the consumer law of the country where you live.
