Effective date: 13 November 2026
1. How these terms fit with Apple's EULA
Typeferry for Mac from the Mac App Store (the "App Store Edition") is licensed to you under Apple's Licensed Application End User License Agreement (the "Standard EULA", https://www.apple.com/legal/internet-services/itunes/dev/stdeula/). These Supplemental Terms add rules for Typeferry Pro bought through the App Store and for the online services the app connects to (online translation and subscription checks).
If these Supplemental Terms conflict with the Standard EULA about your license to use the app, the Standard EULA applies. These Supplemental Terms are between you and Typeferry ("we", "us"), not Apple. We, not Apple, are responsible for the app, its online services and their support. Contact: support@typeferry.com.
By using the App Store Edition's online services or buying Typeferry Pro in the app, you agree to these Supplemental Terms. Our Privacy Policy explains how we handle your data.
2. Who can use Typeferry
You must be at least 13 years old, or older if the law where you live sets a higher minimum age. Purchases are also subject to Apple's rules for your Apple Account, including Family and parental controls.
3. Free and Pro
Free. Without paying you can use:
- on-device translation (the translation built into macOS), with no daily limit;
- online (AI) translation for up to 20 translations filled in from the input bar and 3 screenshot translations per day, plus a daily character limit. When you reach the limit, Typeferry switches to on-device translation for the rest of the day.
Pro is an auto-renewing in-app subscription. It adds:
- window translation (translating a chat window in place as new messages arrive);
- voice input (hold a key, speak, and the translation is filled in);
- online translation without the daily count above, up to 300,000 characters per subscription per day and 2,000,000 per calendar month (shared by all Macs using it, including screenshot translation); once the monthly limit is reached, up to 30,000 characters per day for the rest of that month. Days and months are counted in UTC. These limits protect the service from abuse.
Limits for everyone. Online translation is limited to 1,000 characters per input-bar request and 3,000 characters per screenshot or window request; longer text is translated on your Mac. Window translation uses at most two-thirds of a day's online allowance.
This edition only accepts App Store purchases. Pro bought on our website cannot be used in the App Store Edition, and App Store subscriptions cannot be used in the website edition.
How features differ in this edition. Because Mac App Store apps run in Apple's App Sandbox, some features work differently from the website edition (for example, the input bar appears at the bottom of the window rather than following your text cursor). The App Store product page describes this edition.
We may change features and limits. We will not reduce what a paid Pro subscription includes during a billing period you have already paid for, except where needed for security, abuse prevention or legal reasons; we will give notice of other changes in the app or on our website before your next renewal.
4. In-app subscriptions
- Typeferry Pro is available monthly or yearly. Payment is charged to your Apple Account when you confirm the purchase.
- The subscription renews automatically unless you cancel at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the end of the current period.
- You can manage or cancel your subscription at any time in your App Store account settings. Cancellation takes effect at the end of the current period.
- Prices are shown in the App Store and in the app, in your local currency.
- To use Pro on another Mac signed in with the same Apple Account, use "Restore Purchases" in Typeferry.
5. Refunds
Apple handles all payments and refunds for App Store purchases. To request a refund, use Apple's process (https://reportaproblem.apple.com). The refund rules in our website edition terms do not apply to App Store purchases, and we cannot issue refunds for them ourselves. When Apple refunds or revokes a subscription, Pro ends in the app, and online Pro translation stops as soon as our server receives Apple's notice.
6. Online translation and subscription checks
- If you choose online translation, the text you are translating is sent through our relay server to an AI model hosted by Cloudflare, as described in the Privacy Policy. When you are offline, when the online service is unavailable, slow or returns an unusable result, or when your daily limit is used up, Typeferry translates on your Mac with the translation built into macOS instead. You can choose "On-device only" at any time in Settings.
- While you have Pro, the app sends Apple's signed record of your subscription purchase and a device ID to our license server about once a day, so that online translation gets Pro limits. A subscription can be used for online Pro translation on up to 3 Macs at a time; a Mac that has not checked in for 14 days frees its slot.
- We aim to keep online translation available but do not guarantee that it will be available at all times, in every language, or at a particular speed. We may change or discontinue our online services. If we discontinue online translation for Pro, we will give at least 30 days' notice in the app.
7. Translations are not guaranteed to be accurate
Typeferry uses machine translation (AI models and the translation built into macOS) and text recognition. Translations and recognized text can be wrong, incomplete or inappropriate in tone, and may change the meaning of what you or others wrote. Back-translations and other hints are aids, not guarantees.
- Check translations before you send them. Typeferry fills text into the app you are using; it does not press send for you. You are responsible for what you send.
- Do not rely on Typeferry for legal, medical, financial, safety-critical or other high-stakes communication, contracts or official documents. Use a qualified human translator.
8. Other apps and services
Typeferry works alongside other apps, such as chat and email apps. We are not affiliated with or endorsed by their makers, and their names are trademarks of their owners. You are responsible for following the terms of the apps and services you use with Typeferry.
9. Acceptable use
Do not use Typeferry or our online services to:
- break the law or infringe anyone's rights;
- harass, threaten, defraud, impersonate or deceive people, or to send spam or bulk unsolicited messages;
- create or spread content that sexually exploits children, promotes violence or is otherwise illegal;
- access our servers other than through the Typeferry app, automate or script requests, or resell or share access to our online services;
- get around usage limits or subscription checks, for example by faking device IDs;
- interfere with, overload or attack our services or the services of our providers.
We may limit, suspend or end your access to our online services if we reasonably believe you are breaking this section. This does not affect your Apple subscription itself; contact Apple about refunds.
10. Your content
You keep all rights to the text you type and to the content on your screen. You give us permission to process that content only as needed to provide Typeferry, as described in the Privacy Policy. We do not claim ownership of your content or translations, and we do not use them to train AI models.
11. Warranty, liability and governing law
The Standard EULA's sections on No Warranty, Limitation of Liability, Export and Governing Law also apply to these Supplemental Terms and to our online services. Nothing in these Supplemental Terms limits rights you have as a consumer that cannot be limited by contract.
12. Changes
We may update these Supplemental Terms. We will post the new version with a new effective date and, for changes that materially affect you, tell you in the app and on our website before they take effect. If you keep using the online services after that, the new terms apply; if you do not agree, stop using them and cancel your subscription in your App Store account settings.
