Terms of Service

Last updated: November 8, 2026

These terms are an agreement between you and One Immersion LLC ("we", "us") about Dapple: the website and flashcard app at korean.oneimmersion.com, the Dapple Chrome extension, the Dapple Android app, and related services. By using Dapple you agree to them. Questions: language.flipper@gmail.com.

The service

Dapple offers free flashcards, including importing decks you export from Anki, and an immersion feature that shows Korean words you know on websites you visit. Your study data is stored in your own Google Drive as described in our Privacy Policy.

Your account

You sign in with a Google account and are responsible for activity under it. You must be at least 13 years old, or the minimum age to consent in your country. If you're under 18, a parent or guardian must agree to these terms and handle any purchase.

Free and Premium plans

• The free plan includes flashcards and immersion on a limited number of sites. Premium includes immersion on every site. Current prices are on the pricing page.
• Premium is a subscription, billed in advance (monthly or yearly) through Stripe, and renews automatically at the then-current price until you cancel. Applicable taxes may be added.
• If you subscribe in the Dapple app for iPhone or Android, the purchase is made with Apple (App Store) or Google (Google Play) and charged to your Apple ID or Google Play account. It renews automatically unless you cancel at least 24 hours before the end of the current period. You manage, cancel and request refunds for it in your App Store or Google Play account settings, under Apple's or Google's refund rules; we can't issue refunds for those purchases ourselves. Premium bought in the app also works on this website and in the Chrome extension when you sign in with the same Google account.
• You can cancel any time in Settings → Account → Cancel membership, or through the billing page linked there. Cancelling stops the next renewal; you keep Premium until the end of the period you paid for.
• We may change prices with at least 30 days' notice. A new price applies from your next billing period after the notice, and you can cancel before then.
• If a payment fails, Premium may pause until the payment method is updated.

Refunds

This section is for Premium bought on this website (through Stripe). Purchases made in the App Store or Google Play are refunded by Apple or Google; see above.

If you're not happy, you can get a full refund of a charge within 14 days of it: press Withdraw from contract in Settings → Account (shown during those 14 days), or email language.flipper@gmail.com. After 14 days, charges aren't refunded except where the law requires it. Refunds go back to the original payment method. If you received a refund, the related Premium period ends.

EU and UK customers: right of withdrawal

If you're a consumer in the European Union or the United Kingdom, you have the right to withdraw from a Premium purchase within 14 days of the day you bought it, without giving a reason. Premium starts as soon as you subscribe, at your request. To withdraw, press Withdraw from contract in Settings → Account and confirm, or email language.flipper@gmail.com with a clear statement (for example: "I withdraw from my Dapple Premium subscription bought on [date]"), from the email address of your account. We'll refund the full amount within 14 days of receiving it, using your original payment method, and end Premium. This doesn't limit the 14-day refund above, which applies to everyone. Separately, you can cancel future renewals online at any time in Settings → Account.

Your content

Decks and cards you import or create stay yours, and you can export them any time (Settings → Your data). Only import material you have the right to use; shared Anki decks often come with their own license terms.

Acceptable use

Don't misuse the service: no attempts to break or overload it, get around plan limits or Premium checks, copy or resell the service, or access other people's data. The extension and the Android app's browser change how pages look on your own screen only; you're responsible for following the terms of the sites you use them on.

Learning content

Korean forms, pronunciations, romanizations and examples are generated automatically from your cards and grammar rules. We work hard to make them accurate, but they can contain mistakes and aren't a substitute for a teacher or dictionary when accuracy matters.

Our software

We grant you a personal, non-transferable license to use Dapple while you follow these terms. The software, design and name remain ours. You may not reverse engineer it except where the law allows.

Other services and your accounts

Dapple never asks for your passwords or logins for other websites or services, and doesn't act on them on your behalf. In the Android app's built-in browser you sign in to sites yourself, on their own pages, and your use of each site stays under that site's terms; Dapple isn't affiliated with or endorsed by the sites you visit. It reads Anki export files you choose to import, read-only, and never changes your Anki collection or connects to AnkiWeb.

Third parties

Dapple relies on Google for sign-in and storage, Netlify for hosting, and Stripe, Apple (App Store) and Google (Google Play) for payments, each under their own terms. Anki is a trademark of its owner; Dapple is not affiliated with or endorsed by Anki, AnkiWeb, AnkiDroid or AnkiMobile.

No warranty

Dapple is provided "as is" and "as available". We work to keep it reliable and your data safe, but we can't promise it will be uninterrupted or error-free. Keep your own backups of decks that matter to you; your original Anki collection is never changed by Dapple.

Limitation of liability

To the extent the law allows, we aren't liable for indirect, incidental or consequential losses, and our total liability for any claim is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits rights you have under consumer protection laws that can't be waived.

Ending

You can stop using Dapple at any time. We may suspend or end accounts that break these terms. Unless the law or someone's safety requires faster action, or the breach is serious (such as fraud or attacks on the service), we'll first tell you what's wrong and give you a reasonable chance to fix it. If we ever shut the service down, we'll give at least 30 days' notice and refund any unused part of a paid period; your cards remain in your Google Drive, and you can export them.

Changes

We may update these terms. We'll change the date above and tell you about significant changes before they apply. If you keep using Dapple after that, the new terms apply.

Disputes

If something goes wrong, please email language.flipper@gmail.com first. Most problems can be solved quickly, and we'll try in good faith to resolve it with you within 30 days before either of us goes to court. Either of us may bring an eligible claim in small claims court instead.

Governing law

These terms are governed by the laws of the State of New Jersey, USA, without regard to its conflict-of-law rules. Disputes will be handled in the state or federal courts located in New Jersey. If you're a consumer, nothing in these terms takes away protections you have under the mandatory laws of the country or state where you live, including the right to bring a claim in your local courts where that law gives it to you.
