Terms of use

Last updated: 7 November 2026

1. This agreement

This is an agreement between you and Mirentha Ltd (“Mirentha”, “we”) for your use of the Serialect app for iPhone (“Serialect”). It is between you and Mirentha only, not Apple Inc. (“Apple”). Mirentha, not Apple, is solely responsible for Serialect and its content. By downloading or using Serialect you agree to these terms.

2. Your licence

Mirentha gives you a personal, non-exclusive, non-transferable licence to use Serialect on any Apple-branded product that you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions, except that Serialect may be accessed and used by other accounts associated with the purchaser via Family Sharing or volume purchasing where those apply. You may not copy, modify, rent, lend or redistribute Serialect, or reverse-engineer it except where the law allows.

3. Free use and Serialect Plus

Serialect is free to download. Without paying you get Episode 1 straight away and then one new episode every 7 days, in one language at a time, with no time limit. Listening, word meanings, Read back, import and export all work on the free plan. Writing stories needs an iPhone 15 Pro or later with Apple Intelligence turned on. There is no free trial and no introductory offer.

Serialect Plus is an auto-renewable subscription with two plans, at these UK prices:

• Serialect Plus Monthly: one month, £3.49, renewing monthly.
• Serialect Plus Annual: one year, £24.99, renewing yearly.

Plus adds the next episode as soon as you finish the last, and up to all five languages. The App Store shows each buyer the price in their own currency before they confirm.

Payment is charged to your Apple Account when you confirm the purchase. The subscription renews automatically unless you cancel it at least 24 hours before the end of the current period. Your Apple Account is charged for the renewal, at the plan’s price, within the 24 hours before the period ends. You can manage or cancel the subscription in your Apple Account’s subscription settings, which Serialect’s Settings opens for you under Manage subscription. Family Sharing does not apply to Serialect Plus. You can restore it on another iPhone with the same Apple Account using Restore Purchases, in Serialect’s Settings or on the Plus screen.

If your subscription ends, your words and episodes stay. Everything already in the app stays readable and exportable, and new episodes go back to one every 7 days, in the language you opened last. Refunds are handled by Apple at reportaproblem.apple.com (https://reportaproblem.apple.com).

4. Maintenance and support

Mirentha alone is responsible for providing maintenance and support for Serialect, as described on the support page (https://mirentha.com/apps/serialect/support/). Apple has no obligation whatsoever to furnish any maintenance or support services for Serialect. Mirentha provides maintenance and support as set out here, or as required under applicable law.

5. Warranty

Mirentha alone is responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. If Serialect fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any, for Serialect to you. To the maximum extent permitted by law, Apple has no other warranty obligation whatsoever with respect to Serialect, and any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to any warranty are Mirentha’s sole responsibility. Nothing in these terms affects your statutory rights as a consumer in the UK.

6. Product claims

Mirentha, not Apple, is responsible for addressing any claims by you or any third party relating to Serialect or your possession and use of it, including: (i) product liability claims; (ii) any claim that Serialect fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy or similar legislation.

7. Intellectual property

If any third party claims that Serialect or your possession and use of it infringes that third party’s intellectual property rights, Mirentha, not Apple, will be solely responsible for the investigation, defence, settlement and discharge of that claim.

The word data in Serialect isn’t ours and isn’t covered by this licence. The word frequency lists are FrequencyWords by Hermit Dave, under Creative Commons Attribution-ShareAlike 4.0, and the lemma tables are Lemmatization Lists by Michal Boleslav Měchura, under the Open Database Licence 1.0. Serialect carries both unchanged, and each source, its licence and a link to its free copy are in Settings under Word data and licences.

8. Legal compliance

You represent and warrant that (i) you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a “terrorist supporting” country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.

9. Third-party terms

You must comply with any applicable third-party terms when using Serialect, such as your mobile network’s data agreement, and Apple’s terms for the services it uses on your iPhone.

10. Third-party beneficiary

Apple and Apple’s subsidiaries are third-party beneficiaries of this agreement, and on your acceptance of it Apple will have the right (and will be deemed to have accepted the right) to enforce it against you as a third-party beneficiary.

11. What Serialect is, and isn’t

Serialect writes practice stories with an AI model on your iPhone. They can contain mistakes, and they aren’t a substitute for a teacher, a translator or a dictionary. Word counts and coverage figures are estimates.

• Serialect doesn’t assess your level, and it doesn’t promise any result in a language or an exam.
• A coverage figure is what the app reached on that episode, by its own count. It works towards your target and doesn’t always reach it, and it says so when it doesn’t.
• Word meanings come from Apple’s Translation and can be wrong for a word out of its sentence.
• Read back marks the words the phone didn’t hear. It can miss words and it can guess, so it’s a guide. It doesn’t judge your speech.
• Serialect writes only from its own story outlines. It never rewrites text you bring: imported files give it words, and nothing else.
• You are responsible for what you import, and for what you do with anything you export or send. A file you export is yours to look after.
• If an episode contains something it shouldn’t, use Report this story, Never use this word or Themes off. Each is in the app, and the report is a mail you see and send.

12. Liability and governing law

To the extent the law allows, Mirentha is not liable for a loss that results from relying on a practice story, a word meaning or a figure in Serialect, or from words or stories lost with your iPhone or its backup. Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or for anything else that can’t be limited by law, and your statutory rights are not affected. These terms are governed by the law of England and Wales, and the courts of England and Wales have jurisdiction, except that if you live in Scotland or Northern Ireland you may also bring proceedings there.

13. Contact

Questions, complaints and claims about Serialect: Mirentha Ltd, 71–75 Shelton Street, Covent Garden, London WC2H 9JQ, United Kingdom; email [email protected].

14. Changes

We may update these terms, for example when Serialect gains a feature. The date at the top says when they last changed. If you keep using Serialect after a change, the new terms apply.
