Terms of use

Effective 12 October 2026.

Grandmaster Flash is a language-learning app operated by Disco Media Pty Ltd (“we”, “us”). These terms cover the mobile app, its sync service, its assistant connector, Flash Free, and Flash Plus. By creating an account or using the service, you agree to them. If you don’t agree, don’t use the service.

If you got the app from the App Store, Apple’s Licensed Application End User License Agreement also applies. Our privacy policy explains how we handle your information.

Your account

• You must be at least 13. If you are under the age of majority where you live, you need a parent’s or guardian’s permission.
• One person per account. Keep access to your email and connected assistants secure; you are responsible for activity on your account.
• Give us an email address you control. We use it to sign you in and to contact you about your account.

What the service is for

Grandmaster Flash is for studying languages with flashcards and audio. You create and edit decks through ChatGPT, Claude, or another assistant you connect, and study them in the app. It is not a general file store, backup service, or audio host.

Your content

• Decks, cards, notes, and audio you create or supply remain yours. You give us permission to store, copy, process, and display them, and to send card text to our audio provider, only as needed to run the service for you.
• You are responsible for your content and for having the right to use it, including any audio you supply and any voice recorded in it.
• Translations, examples, pronunciation, and audio are produced by AI assistants and text-to-speech. They can be wrong or sound unnatural. Check anything important with a reliable source.
• Your assistant provider (for example OpenAI or Anthropic) handles your conversations under its own terms. We are not responsible for what an assistant writes or does outside our connector.

Acceptable use

You must not use Grandmaster Flash to:

• Store, host, or distribute material unrelated to learning, such as files, archives, music, podcasts, or other audio or data, or use cards or audio as storage for anything else.
• Create or store content that is illegal where you live or in Australia, or that breaks Apple’s or Google’s app store rules. This includes sexual content involving minors, sexually explicit or gratuitously violent content, content that promotes terrorism, violence, or self-harm, hate or harassment directed at people, and content that infringes someone else’s copyright or other rights.
• Impersonate a real person, including by supplying or generating audio in someone’s voice without their consent, or include other people’s private information.
• Get around plan limits or safeguards: opening extra accounts to reuse the free allowance, sharing or reselling an account or Flash Plus, generating audio for anyone else’s use, or manipulating requests, retries, or deletions to obtain more generation than your plan includes.
• Use automated tools to access the service other than an assistant connector you have authorized; scrape, overload, probe, or interfere with the service; or copy, reverse engineer, or resell it.

Plans and Flash Plus

• Flash Free includes unlimited decks and text cards, offline study, and sync, plus a one-time allowance of generated audio and limited audio storage. Flash Plus raises the generated-audio allowance each month and increases storage. Current allowances are shown in the app under Settings → Plan & usage.
• Generated audio is measured in characters. Unused characters don’t carry over, and restoring or repurchasing a subscription doesn’t reset the current month. Allowances are for one person’s own study.
• Flash Plus is sold through the App Store. Apple handles payment, renewal, and refunds. The subscription renews automatically until you cancel in your Apple Account settings at least 24 hours before the period ends. Deleting your Grandmaster Flash account does not cancel it.
• When Flash Plus ends, your cards and existing audio stay and you can keep studying; new audio is limited to the Flash Free allowance.
• We may change plans, prices, or allowances for future periods. We will tell you in advance of changes that reduce what an active subscription includes, and price changes follow Apple’s notification rules.

Suspension and termination

We may remove content, limit audio generation, suspend, or close an account that breaks these terms, puts the service or other people at risk, or that we are required by law to act on. For clear or serious abuse we may act immediately and without notice; otherwise we will usually warn you first. We may report illegal content to the relevant authorities.

If we close your account for breaking these terms, you are not entitled to a refund from us for unused Flash Plus time; refund requests go to Apple. If we close an account for any other reason, or discontinue the service, we will give reasonable notice where we can so you can cancel Flash Plus. If you think we made a mistake, email [email protected].

You can stop using the service and delete your account at any time in Settings → Account.

The service

We work to keep Grandmaster Flash available and your data safe, but the service is provided as it is and may change, have interruptions, or depend on providers such as Apple, our hosts, assistant providers, and ElevenLabs. Keep your own copy of anything you can’t afford to lose.

Liability

Nothing in these terms excludes rights you have under the Australian Consumer Law or other laws that can’t be excluded. To the extent the law allows, we are not liable for indirect or consequential loss, and our total liability to you is limited to the amount you paid for Flash Plus in the 12 months before the claim, or to supplying the service again.

Changes and contact

We may update these terms. We will post the new version here with its effective date and, for significant changes, tell you in the app or by email. Continuing to use the service after a change means you accept it. These terms are governed by the laws of Victoria, Australia, and the courts of Victoria have non-exclusive jurisdiction.
