Terms of Use

By accessing or using AnkiCat (the "Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree, do not use the Service. These Terms form a binding agreement between you and MARTINS HIGH QUALITY SOFTWARE LTDA ("AnkiCat", "we", "us", or "our").

AnkiCat is a spaced-repetition flashcard study service with optional AI-assisted card generation (Deck Drafting). It is offered as native iOS and Android applications. A free plan is available with limited features (2 study sessions and 2 quizzes per day). Paid access is Student Pro, sold as an auto-renewing Monthly or Yearly subscription. What is included, whether a free trial applies, and the price you will be charged are shown in the app at checkout and may change as described in Section 8.

You must be at least 13 years old to use AnkiCat. In the European Economic Area and the United Kingdom, if you are under the age of digital consent in your country (16 by default, or the lower age your country has set, no younger than 13), a parent or legal guardian must consent on your behalf. Elsewhere, if you are between 13 and the age of majority in your jurisdiction, you may only use the Service with the consent of a parent or legal guardian. You may not use the Service if you reside in a country subject to U.S. trade embargo or appear on a U.S. Government denied-persons list.

• You must provide accurate and current information when creating an account.
• You are responsible for safeguarding your credentials and for activity that occurs under your account.
• Accounts are for a single individual; sharing is not permitted.
• We may suspend or terminate accounts that violate these Terms.

You retain all ownership rights to the notes, cards, decks, and other materials you submit ("User Content"). By submitting User Content, you grant AnkiCat a worldwide, royalty-free, non-exclusive license to host, store, process, transmit, display, and create technical derivative works of that content solely to operate the Service for you, including using AI providers to generate cards from your inputs.

We may use anonymized and aggregated derivatives of User Content to improve the Service. We will not use identifiable User Content to train AI models without your separate, explicit opt-in.

You represent that you have all necessary rights to your User Content and that it does not infringe any third-party rights or violate any law.

You agree not to:

• Use the Service for any illegal, harmful, or fraudulent purpose.
• Reverse engineer, decompile, or attempt to extract source code.
• Scrape, crawl, or use the Service to assemble datasets except as expressly permitted.
• Use AnkiCat to train competing AI or flashcard products.
• Upload material that infringes intellectual property, contains malware, or contains personal data of others without authorization.
• Harass, threaten, or abuse other users or our staff.
• Circumvent security, rate limits, or access controls.

AnkiCat offers a free plan with limited daily usage, plus Student Pro, a paid auto-renewing subscription that unlocks unlimited study, AI features, and advanced analytics. Two billing periods are offered:

• Student Pro Monthly. List price US$9.99 per month, billed in advance. Auto-renews each month until cancelled. No free trial.
• Student Pro Yearly. List price US$59.99 per year, billed in advance. Auto-renews each year until cancelled. Includes a 7-day free trial. If you do not cancel at least 24 hours before the trial ends, Apple or Google will charge the Yearly price and the subscription will continue to auto-renew.

Included with Student Pro. Offline study, custom themes, a limited AI credit allowance for Deck Drafting, Quiz scoring, and advanced analytics, as shown in the app at purchase. Extra AI credit packs are not sold. If a one-time lifetime purchase is offered, it will be identified at checkout as a one-time payment and is not an auto-renewing subscription.

Our goals of lower subscription fees and self-hosted AI are future aspirations, with no guaranteed timeline, price reduction, or capability. They are not guaranteed included subscription benefits. Your subscription provides the benefits shown at checkout.

Prices. List prices are in United States dollars (USD): Monthly US$9.99 and Yearly US$59.99. When you subscribe in the iOS or Android app, Apple or Google displays and charges the price in your storefront currency, which may include applicable taxes. The amount you pay is the price shown by Apple or Google at checkout, not a currency conversion we calculate ourselves.

Billing and cancellation. iOS subscriptions are processed by Apple as in-app purchases under the Apple Media Services Terms and Conditions. Android subscriptions are processed by Google under Google Play terms. We use RevenueCat, Inc. to sync subscription status (entitlements) to your AnkiCat account. Payment is charged to your Apple ID or Google account at confirmation of purchase (or at the end of a free trial). Subscriptions auto-renew unless you cancel at least 24 hours before the end of the current trial or paid period. You will be charged the then-current price at each renewal. You may cancel at any time, including during a free trial, through: (1) the AnkiCat app under Settings, Subscription (this row is shown only while you have an active Student Pro subscription); (2) on iOS, Settings, your Apple ID, Subscriptions; or (3) on Android, Google Play, Payments and subscriptions. Cancellation stops the next renewal. You keep access until the end of the current trial or paid period. AnkiCat does not cancel App Store or Play subscriptions from its own servers.

Refunds. Refunds for App Store and Google Play purchases are handled by Apple and Google under their respective policies. Email support@ankicat.com if you need help finding those flows.

Price and feature changes. We may change list prices or what Student Pro includes. For existing auto-renewing subscribers, we will give at least 30 days' notice where required by law. Apple or Google may also require your consent before charging a new price.

Consumer rights. Where applicable, you may have a statutory right to withdraw from a distance contract within 14 days (European Union) or 7 days (Brazil, CDC Art. 49). For digital content delivered immediately, you may be asked to expressly waive the withdrawal right at checkout. Nothing in these Terms limits mandatory consumer rights under applicable law.
