1.Agreement

These Terms of Use (“Terms”) are an agreement between you and Deniz Maral, the developer of MarAI Keyboard (“MarAI”, “we”, “us”). They apply to the MarAI Keyboard app, its keyboard and share extensions, MarAI Pro, and these web pages (together, the “App”). By downloading or using the App, you agree to these Terms.

You get the App from Apple’s App Store, so Apple’s Licensed Application End User License Agreement (the “Apple EULA”) and the App Store’s Usage Rules also apply. These Terms add to the Apple EULA. If they conflict, the Apple EULA controls to the extent of the conflict.

If you are under the age of majority where you live, you may use the App only with the involvement of a parent or guardian who agrees to these Terms. How we handle information is described in the Privacy Policy.

2.The App

MarAI is a keyboard for iPhone and iPad that offers suggestions, autocorrection, next-word predictions, language detection, and learning from how you type. Core typing features are free, including up to two languages. MarAI Pro unlocks additional features, which are described in the App before you buy. They currently include unlimited languages, the layout builder, Pro and custom themes, accent keys, special characters, text snippets, swipe gestures, statistics, Date & Time, Translate and AI Writing.

The free features, the Pro features and the free limits may change over time, as described in Section 5.

3.Your licence

We grant you a personal, non-exclusive, non-transferable, revocable licence to use the App on Apple devices that you own or control, as permitted by the Apple EULA and the App Store’s Usage Rules. The App is licensed to you, not sold. We and our licensors keep all rights not expressly granted to you.

4.Acceptable use

You agree not to:

  • copy, modify, distribute, sell or rent the App, or create derivative works from it;
  • reverse engineer, decompile or disassemble the App, or extract its dictionaries or language models, except where the law allows this despite this restriction;
  • bypass or interfere with purchase checks, Pro features or security measures;
  • use the App to break the law or infringe anyone’s rights;
  • share content with the App’s training features that you do not have the right to use.

5.MarAI Pro

Plans

MarAI Pro is available as an auto-renewing monthly or annual subscription, or as a one-time Lifetime purchase. The current plans, prices and any introductory offer are shown in the App before you buy, and prices may vary by country.

How billing works. Payment is charged to your Apple Account when you confirm the purchase. Subscriptions renew automatically at the price shown unless canceled at least 24 hours before the end of the current period; your account is charged for the renewal within the 24 hours before the period ends. Manage or cancel your subscription in your App Store account settings. Any unused part of a free trial is forfeited when you buy a subscription. The Lifetime plan is a one-time purchase and does not renew.

Free trials and offers

If a free trial or other introductory offer is shown, it is available only to people Apple considers eligible, usually once per Apple Account for a subscription group. Unless you cancel at least 24 hours before a free trial ends, the subscription starts and renews at the regular price.

Cancelling

You can cancel at any time in your App Store subscription settings. Deleting the App does not cancel a subscription. After you cancel, Pro stays available until the end of the period you already paid for.

Price changes

We may change subscription prices. Apple notifies you in advance, and where required by Apple or by law, asks for your consent before a higher price applies to your subscription. A price change never affects a period you have already paid for.

Refunds

Apple handles all payments, so we cannot issue refunds ourselves. You can request a refund from Apple at reportaproblem.apple.com, and Apple decides under its policies. Nothing in these Terms limits any refund or withdrawal right you have under the law where you live. If Apple refunds a purchase, the Pro access it provided ends.

Family Sharing and devices

Where a plan supports Family Sharing in the App Store, members of your Family Sharing group can use Pro under Apple’s rules. Your purchase works on your other devices signed in to the same Apple Account. Use Restore Purchases in the App if Pro doesn’t unlock.

Lifetime and earlier purchases

The Lifetime plan gives you Pro for as long as we offer and support the App, without further payments. It does not guarantee that the App, any feature, or any iOS version will be supported forever. If you bought MarAI Pro as a one-time purchase before subscriptions were introduced, it continues to unlock Pro.

Checking your purchase

The App confirms your purchase with Apple and remembers the result on your device, so Pro keeps working when you are temporarily offline. A subscription that has ended stops unlocking Pro once the App can confirm it has ended, and in any case after a grace period of about 16 days, similar to Apple’s billing grace period.

When Pro ends

If your subscription ends or a purchase is refunded, Pro features stop working. We do not intentionally delete what you created with Pro, such as layouts, themes, snippets or language settings; it becomes available again if you get Pro again. Languages beyond the free limit are paused, not deleted.

Changes to Pro

We improve the App regularly and may add, change or remove features, in both the free version and Pro. We will not materially reduce the Pro features available during a subscription period you have already paid for. If we stop offering Pro, or remove a significant Pro feature, you can seek a refund from Apple for any unused paid period as required by law.

6.Your content and learned data

What you type, and the words the App learns from it, belong to you. We don’t claim any ownership of them and do not receive them, as explained in the Privacy Policy. The App processes this data on your device, and in your iCloud if iCloud Sync is on, only to provide its features.

Learned data lives on your devices and in your iCloud. It can be lost, for example if you delete the App, reset your device, turn off iCloud, or if a sync conflict occurs. Keep your own backups of anything important. To the extent permitted by law, we are not responsible for lost learned words, settings or other data.

7.Language packs and online features

Dictionaries and language models are downloaded after you install the App, so you need an internet connection to add or update a language. Downloads use Apple’s iCloud services, and we do not guarantee that every language, pack or update will always be available. Features that rely on the internet or on Apple’s services may be interrupted, limited or unavailable.

8.Suggestions, AI Writing and Translate

Autocorrection, suggestions, predictions, capitalisation, AI Writing and Translate are automated and can be wrong, incomplete or inappropriate for your situation. They can change the words you type. Always review your text before you send, post or rely on it. You are responsible for what you write and send.

AI Writing uses Apple Intelligence and Translate uses Apple’s Translation framework. They are available only on supported devices, iOS versions, languages and regions, and depend on Apple, which may change or withdraw them. Their output is not professional, legal, medical, financial or other expert advice.

9.Clipboard history and Private Mode

Clipboard history tries to skip passwords and one-time codes and to hide sensitive details such as card numbers. This filtering is automatic and can miss things. Private Mode pauses learning and clipboard capture while it is on. Neither feature guarantees that sensitive content is never stored on your device, so avoid copying information you do not want kept.

10.Feedback

If you send us ideas, suggestions or reports, you allow us to use them to improve the App without any obligation or payment to you. We will handle any personal information in them as described in the Privacy Policy.

11.Third-party services and open source

The App relies on services from Apple, including the App Store, iCloud, Apple Intelligence and Translation, which are governed by Apple’s own terms. We are not responsible for third-party services, apps or websites, including websites you share with the App.

The App includes open-source software and data under their own licences, including:

Those licences apply to those components, and nothing in these Terms restricts rights they grant you.

12.Intellectual property

The App, including its design, code, dictionaries, language models, text and graphics, and the MarAI name and logo, are owned by us or our licensors and protected by intellectual property laws. Apple, iPhone, iPad, iCloud, App Store and Apple Intelligence are trademarks of Apple Inc. MarAI is not affiliated with or endorsed by Apple.

13.Disclaimer of warranties

To the extent permitted by law, the App is provided “as is” and “as available”, without warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, accuracy, and non-infringement. We do not warrant that the App will be uninterrupted, error-free, compatible with every app or device, or that suggestions, corrections or other output will be accurate.

This does not affect warranties or guarantees that cannot be excluded under the law that applies to you, including consumer guarantees.

14.Limitation of liability

To the extent permitted by law, we are not liable for any indirect, incidental, special, consequential or punitive damages, or for loss of data, profits, revenue or goodwill, arising from or related to the App, including messages or content sent with wrong suggestions or corrections. Our total liability for all claims relating to the App is limited to the greater of the amount you paid for MarAI Pro in the 12 months before the event giving rise to the claim, or CHF 50.

These limits do not apply to liability for intent or gross negligence, for death or personal injury caused by our negligence, or to any other liability that cannot be limited or excluded by law.

15.Indemnity

To the extent permitted by law, you agree to compensate us for reasonable losses and costs, including legal fees, arising from your breach of these Terms or your misuse of the App. This does not apply where you are not at fault, and it does not limit your rights as a consumer.

16.Ending these Terms

You can stop using the App at any time by deleting it. Remember to cancel any subscription in your App Store settings. Your licence ends automatically if you materially breach these Terms. We may stop offering or supporting the App or any part of it. Sections that by their nature should continue, such as those on intellectual property, disclaimers, limitation of liability and governing law, survive after these Terms end.

17.Changes to these Terms

We may update these Terms, for example to reflect new features or legal requirements. We will post the updated Terms here with a new effective date and summarise the main changes at the top. If a change materially affects your rights, we will give you reasonable notice in the App or on this page before it applies. Continuing to use the App after the effective date means you accept the updated Terms. Changes do not apply to disputes that arose before they took effect, or to a paid subscription period you have already started, where applying them would disadvantage you.

18.Apple-specific terms

Because you got the App from the App Store, you and we acknowledge that:

  • these Terms are between you and us, not Apple, and we, not Apple, are solely responsible for the App and its content;
  • Apple has no obligation to provide maintenance or support for the App;
  • if the App fails to conform to an applicable warranty, you may notify Apple and Apple will refund the purchase price, if any; to the extent permitted by law, Apple has no other warranty obligation for the App;
  • Apple is not responsible for any claims by you or third parties relating to the App, including product liability claims, claims that the App fails to meet legal or regulatory requirements, and consumer protection or privacy claims;
  • if a third party claims that the App or your use of it infringes their intellectual property rights, we, not Apple, are responsible for investigating, defending, settling and discharging that claim;
  • you confirm that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not on any U.S. Government list of prohibited or restricted parties;
  • you must comply with applicable third-party terms when using the App;
  • Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

19.Governing law and disputes

These Terms are governed by Swiss law, excluding its conflict-of-law rules and the United Nations Convention on Contracts for the International Sale of Goods. The courts of Switzerland have jurisdiction over disputes relating to these Terms or the App.

If you are a consumer, you also keep the protection of the mandatory laws of the country where you live, and you may bring proceedings in the courts of that country where those laws allow it. Before starting formal proceedings, please contact us so we can try to resolve the issue.

20.General

  • If any part of these Terms is found invalid or unenforceable, the rest remains in effect, and the invalid part is replaced by a valid provision that comes closest to its purpose.
  • Not enforcing a provision is not a waiver of our right to enforce it later.
  • You may not transfer your rights under these Terms. We may transfer ours to a successor of the App, without reducing your rights.
  • These Terms, together with the Apple EULA and the Privacy Policy, are the entire agreement between you and us about the App.
  • If these Terms are translated, the English version controls to the extent permitted by law.
