TERMS OF USE – LORO

Effective Date: September 7, 2026 Last Updated: September 7, 2026

Welcome to Loro.

These Terms of Use ("Terms") govern your access to and use of the Loro application, website, content, and related services provided by Loro.

Loro is developed and operated by:

Developer: NGÔ NGỌC THỂ Type: Individual Developer Country: Vietnam Email: ngothe.genz@gmail.com Website: tramchuyenke.com Terms of Use: tramchuyenke.com/loro/terms Privacy Policy: tramchuyenke.com/loro/privacy

By downloading, installing, accessing, or using Loro, you acknowledge that you have read and agree to these Terms to the extent permitted by applicable law.

If you do not agree to these Terms, you should stop using Loro and may uninstall the application from your device.

1. About Loro

Loro is a language-learning application focused on activities such as:

vocabulary learning;
flashcards;
review activities;
quizzes;
learning statistics;
progress tracking;
courses and educational content;
prompt-generation tools;
games and other language-learning methods.

Some features may operate entirely on your device, while certain shared content, such as vocabulary or courses, may be downloaded from Loro servers.

Loro may modify, add, or remove features over time.

2. Age Requirements

Loro is designed for users 13 years of age or older.

Loro is not designed or intentionally marketed to children under the age of 13.

Where the laws of a country or region require a higher minimum age for a person to independently agree to these Terms or to related data-processing activities, the minimum age required by local law will apply.

If you are not old enough to agree to these Terms independently under the laws of your place of residence, you should use Loro only with the permission of your parent or legal guardian where permitted by law.

Parents and legal guardians are responsible for supervising minors' use of devices and applications where appropriate.

3. No User Account Required

The current version of Loro does not require users to create an account in order to use its main learning features.

Loro currently does not provide:

email registration;
password-based login;
Google Sign-In;
Sign in with Apple;
server-based user profiles.

Your use of Loro is therefore primarily associated with your device and locally stored data rather than an online account.

If Loro introduces account functionality in the future, these Terms and the Privacy Policy may be updated.

4. License to Use the Application

Subject to your compliance with these Terms, Loro grants you a:

limited;
personal;
revocable in the event of a breach of these Terms;
non-exclusive;
non-transferable;
non-sublicensable;

license to install and use Loro for personal, educational, and other lawful purposes on devices that you own or control, in accordance with the rules of the applicable application distribution platform.

You do not acquire ownership of Loro's source code, designs, trademarks, or other intellectual property.

The application is licensed, not sold.

5. Prohibited Conduct

Unless otherwise required by applicable law or permitted by an applicable open-source license, you may not:

unlawfully copy or distribute the application;
resell or sublicense Loro;
impersonate Loro or its developer;
modify the application in order to bypass security measures;
attempt to gain unauthorized access to systems or servers;
use bots or automated tools in a way that places unreasonable load on the service;
exploit vulnerabilities to disrupt the service;
distribute malware through Loro services;
use Loro for unlawful activities;
use Loro content in a way that infringes intellectual property rights;
unlawfully interfere with advertising, analytics, or technical systems;
falsify requests or data in a way that may harm Loro or third parties.

Restrictions on reverse engineering, decompilation, or analysis of the application apply only to the extent such restrictions are permitted by applicable law.

6. Learning Data Stored on the Device

Loro may store learning-related data locally on your device, including:

learned vocabulary;
saved vocabulary;
courses;
progress;
scores;
learning history;
statistics;
correct and incorrect answer results;
review data;
streaks;
learning settings;
content created by you within the application.

Under the current architecture, this learning data is not synchronized to a Loro account or Loro server.

Because the data is stored locally, it may be lost if:

you uninstall the application;
you delete application data;
your device is lost or damaged;
the operating system removes application data;
you reset your device;
you intentionally use the delete-all-data feature;
a device or storage failure occurs outside Loro's reasonable control.

If Loro provides an export feature and you wish to keep a separate copy of your data, you should use that feature where appropriate.

7. Deleting Data

Loro may provide a Delete All Learning Data feature.

When you confirm this action, locally stored data within the scope displayed by the application may be permanently deleted.

Deletion may be irreversible.

Loro does not guarantee that data intentionally deleted by the user can be recovered.

Backups created by the operating system, device cloud services, or other third-party services may be outside Loro's direct control.

8. Educational Content

Loro aims to provide useful and accurate learning content.

However, language may vary depending on:

context;
region;
dialect;
time period;
usage;
level of formality;
reference source.

Accordingly, translations, definitions, examples, pronunciation guidance, exercises, or other educational content may contain errors or may not be appropriate for every context.

You should treat Loro as a learning support tool, not as the sole source for making important decisions.

Loro may correct or update content when errors are identified or when improvements are needed.

9. No Guarantee of Learning Results

Language-learning outcomes depend on many factors, including:

study time;
level of practice;
prior knowledge;
learning method;
individual ability;
language environment.

Loro does not guarantee that use of the application will:

result in a specific proficiency level within a particular period;
guarantee passing an examination;
guarantee a particular score;
guarantee communication ability;
replace teachers or professional education programs.

Statistics provided by Loro are intended only to help users monitor their learning progress.

10. Learning Statistics and Algorithms

Loro may use learning data stored on the device to:

calculate accuracy rates;
determine progress;
select content for review;
analyze results;
recommend learning activities;
generate statistics.

These results are generated by algorithms and should be regarded as informational.

The algorithms may change between application versions in order to improve the learning experience.

11. Prompt Generation and AI Services

Loro may provide features that help users generate prompts for use with artificial intelligence services.

For example, prompts may be used to:

generate vocabulary lists;
create course content;
analyze learning results;
generate sentences or passages;
generate structured learning content.

Under the current version, Loro does not automatically send prompts to OpenAI, Gemini, or any other third-party AI service.

Users independently decide:

whether to copy a prompt;
which AI service to use;
what content to submit;
whether to accept the terms of that AI service.

When you leave Loro and submit content to an external AI service, your relationship with that service is governed by the terms and policies of the relevant provider.

Loro does not control and does not guarantee:

that AI-generated responses are always accurate;
that AI services are always available;
that AI-generated content is appropriate in every situation;
that external AI providers process data in the same way as Loro.

You should avoid including passwords, API keys, financial information, sensitive health information, or confidential data in prompts unless it is truly necessary.

12. Content Generated by External AI Services

If you use a prompt generated by Loro with an external AI service, any content returned by that AI service is not content directly generated or reviewed by Loro.

Loro does not guarantee the:

accuracy;
completeness;
legality;
timeliness;
suitability;
non-infringement of third-party rights;

of content produced by an independent AI service.

You are responsible for reviewing such content before relying on it for important purposes.

13. Advertising

Loro may display advertisements provided by Google AdMob or supported advertising partners.

Advertisements may include:

banners;
interstitial advertisements;
rewarded advertisements;
other supported advertising formats.

The display of an advertisement does not mean that Loro:

owns the advertised product;
endorses the advertised product;
guarantees its quality;
acts as the seller;
participates in the transaction between the user and the advertiser.

If you interact with an advertisement or visit a third-party website or application, your subsequent activity is governed by that third party's terms and policies.

14. Personalized Advertising and Privacy

Depending on:

your country;
your age;
device settings;
user consent;
Google policies;
Apple or Google Play policies;
applicable law;

Loro may display personalized, non-personalized, contextual, or limited advertisements.

In regions where consent is required, Loro may display a privacy-management interface before certain advertising activities occur.

Users may be able to change privacy choices through Loro's Settings section.

More information about advertising-related data processing is available in the Privacy Policy:

tramchuyenke.com/loro/privacy

15. Notifications

Loro may provide local notifications for purposes such as:

study reminders;
review reminders;
task reminders;
functional notifications.

Users may deny or disable notification permissions through their device settings.

Disabling notifications does not prevent users from accessing Loro's core learning features.

16. Internet Connection and Network Charges

Certain features may require an Internet connection to download:

vocabulary;
courses;
updated content;
configuration data;
advertisements;
other resources.

You are responsible for:

your Internet connection;
mobile data charges;
carrier fees;
any fees imposed by your Internet provider.

Loro is not responsible for the quality or availability of telecommunications networks provided by third parties, except where applicable law requires otherwise.

17. Third-Party Services and Links

Loro may use or link to third-party services such as:

Google AdMob;
Apple App Store;
Google Play;
websites;
AI services selected independently by users;
infrastructure providers.

These services operate independently.

Your use of them may be subject to the separate terms and policies of the relevant provider.

Loro does not control the content or activities of independent third-party websites and services.

18. Intellectual Property

Unless otherwise stated, rights relating to:

the Loro name;
logo;
user interface design;
source code;
software structure;
graphics;
content created by Loro;
documentation;
databases compiled by Loro;
trademarks;

belong to the Loro developer or the applicable lawful licensor.

Permission to use the application does not transfer any intellectual property rights to the user.

19. Third-Party Content and Resources

Certain components of Loro may use:

open-source libraries;
fonts;
icons;
data;
content;
software;

provided under third-party licenses.

Such components remain subject to their respective licenses.

If an open-source license grants users broader rights than these Terms, the applicable open-source license will take precedence with respect to that component.

20. User-Created Content

Loro currently does not provide a public social network, forum, or public-posting system.

Content or courses created by users are primarily stored on their devices.

Users are responsible for ensuring that content they create, enter, or use does not:

violate applicable law;
infringe copyright;
infringe trademarks;
violate privacy rights;
contain content the user has no right to use.

Loro does not claim ownership of personal learning content merely because that content is created or stored within the application.

21. Exporting and Sharing Content

If Loro allows data to be exported or shared, users independently choose:

what content to export;
which application will receive the data;
who will receive it;
where it will be stored.

Once data leaves Loro as a result of an intentional user action, Loro cannot fully control how another service or recipient processes that data.

You should review content before sharing it to avoid unintentionally disclosing information you do not wish to make available.

22. Versions and Updates

Loro may release updates in order to:

fix bugs;
improve performance;
update content;
add features;
modify the user interface;
improve security;
comply with application-store requirements;
comply with applicable law.

Certain features may require a newer version of the application in order to continue functioning.

To the extent permitted by law, Loro is not required to maintain every feature or design from previous versions indefinitely.

23. Modification or Discontinuation of Services

Loro may:

modify features;
change content sources;
temporarily suspend a service;
remove a feature;
stop supporting a version;
discontinue the application entirely;

where reasonably necessary for reasons such as:

technical requirements;
security;
legal compliance;
operational costs;
platform changes;
product strategy.

If a change materially affects user rights, Loro will endeavor to provide reasonable notice where required by law or where reasonably practicable.

Mandatory consumer rights under applicable law are not excluded by this provision.

24. Availability of the Service

Loro aims to keep the application operating reliably but does not guarantee that the service will:

operate continuously 24/7;
never contain errors;
never be interrupted;
be compatible with every device;
continue to support every operating-system version.

Interruptions may occur due to:

maintenance;
software errors;
hosting failures;
network failures;
API changes;
failures affecting Google, Apple, or other third parties;
natural disasters or events outside Loro's reasonable control.

25. Device Security

Because much of Loro's data is stored on the device, users are responsible for taking appropriate measures to protect their devices.

For example:

use a device passcode;
protect the device from unauthorized access;
avoid installing untrusted software;
update the operating system where appropriate.

Loro does not control users' devices and cannot prevent every form of unauthorized device access.

26. Not Professional Advice

Loro is an educational application.

Content provided by Loro does not constitute:

legal advice;
medical advice;
financial advice;
investment advice;
professional career advice;
an official language-proficiency certification.

You should not rely solely on Loro content when making decisions that may have significant legal, financial, health, or professional consequences.

27. Disclaimer of Warranties

To the maximum extent permitted by applicable law, Loro is provided on an "as is" and "as available" basis.

The developer does not make an absolute guarantee that:

all content will be error-free;
all translations will always be completely accurate;
the application will be compatible with every device;
the application will never be interrupted;
all locally stored data can always be recovered;
any feature will remain available indefinitely;
Loro will produce a specific learning result.

Nothing in this section excludes any warranty, consumer right, or remedy that cannot lawfully be excluded.

28. Limitation of Liability

To the maximum extent permitted by applicable law, the Loro developer will not be liable for indirect, incidental, special, or consequential damages arising solely from events outside the developer's reasonable control.

Examples may include losses resulting from:

users intentionally deleting local data;
loss or damage to a device;
failures of third-party services;
network failures;
actions of external AI services;
third-party advertising content;
users relying on educational content without verification in an important context.

Nothing in these Terms is intended to:

exclude liability that cannot lawfully be excluded;
limit mandatory consumer rights;
exclude liability for intentional misconduct or any circumstance where applicable law prohibits such limitation.

If the laws of your country do not permit a particular limitation in this section, that limitation will not apply to the extent required by law.

29. Responsibility for Violations

To the extent permitted by law, if your intentional unlawful use of Loro or serious violation of these Terms directly causes claims, losses, or reasonable expenses to the developer, you may be responsible for the resulting consequences under applicable law.

This provision is not intended to impose unreasonable liability on consumers.

30. Restriction of Use

Because Loro currently does not use user accounts, Loro generally cannot "suspend an account."

However, the developer may implement reasonable technical measures to prevent:

attacks on servers;
destructive automated requests;
exploitation of vulnerabilities;
advertising fraud;
unauthorized API access;
conduct that threatens the system or other users.

Such measures will be applied reasonably and in accordance with applicable law.

31. Ending Your Use of Loro

You may stop using Loro at any time by:

no longer opening the application;
deleting local data;
uninstalling Loro.

Your license to use Loro may terminate if you materially breach these Terms, to the extent permitted by applicable law.

Provisions relating to intellectual property, liability, disputes, and other matters that by their nature should survive may continue to apply after you stop using Loro.

32. Apple App Store

If you download Loro from the Apple App Store, you acknowledge that:

Apple is not the developer of Loro;
responsibility for Loro remains with the developer to the extent required by applicable law;
use of the application is also subject to Apple App Store usage rules;
Apple services are governed by Apple's separate terms.

If the developer does not provide a separate Custom EULA through App Store Connect, the Apple Standard End User License Agreement may apply to the license for applications distributed through the App Store.

If these Terms conflict with a mandatory Apple requirement that applies to application distribution, the relevant mandatory Apple requirement will apply to the extent necessary for that platform.

33. Google Play

If you download Loro from Google Play:

your use of Google Play is governed by Google's terms;
Google does not become the developer of Loro merely by distributing the application;
certain platform or advertising features may be provided by Google;
users must comply with Google's lawful rules when using Google services.

Loro's Terms and Google's terms govern different relationships and may apply at the same time.

34. Payments and Subscriptions

The current version of Loro does not provide subscriptions or direct paid features covered by these Terms.

If Loro later introduces:

Premium features;
subscriptions;
In-App Purchases;
paid digital products;

additional or updated terms regarding:

pricing;
billing periods;
automatic renewal;
cancellation;
refunds;
trials;

will be provided before or at the time those payment features become available.

Payments processed through the App Store or Google Play may also be subject to the payment policies of the applicable platform.

35. Privacy

Data processing relating to Loro is described in the:

Loro Privacy Policy tramchuyenke.com/loro/privacy

The Privacy Policy is a separate document that supplements these Terms.

Agreeing to these Terms does not automatically constitute consent to every type of data processing where applicable law requires separate consent.

For example, Loro may request separate consent for personalized advertising or tracking where required.

36. Changes to These Terms

Loro may update these Terms when:

application features change;
the business model changes;
services are added;
providers change;
applicable law changes;
Apple or Google changes its requirements;
unclear or inaccurate provisions need to be corrected.

The Last Updated date at the beginning of this document will be changed when a new version is published.

For material changes that significantly affect user rights or obligations, Loro may provide notice within the application or through another appropriate method where required by law.

Continued use after updated Terms take effect may constitute acceptance of the updated Terms to the extent permitted by applicable law.

Where applicable law requires explicit consent to a change, Loro will not rely solely on continued use of the application as evidence of consent.

37. Governing Law

These Terms are prepared under the laws of Vietnam because the Loro developer operates from Vietnam.

However, if you are a consumer in another country or region, you remain entitled to mandatory consumer protections provided by the laws of your place of residence that cannot lawfully be waived by contract.

Nothing in these Terms is intended to remove those mandatory rights.

38. Dispute Resolution

If a problem arises in connection with Loro, users are encouraged to first contact:

ngothe.genz@gmail.com

so that the developer has an opportunity to review and address the issue.

The parties may attempt to resolve disputes through good-faith communication before using formal dispute-resolution mechanisms.

If a dispute cannot be resolved, it may be handled by a competent authority, court, or dispute-resolution mechanism under applicable law.

Nothing in these Terms requires consumers to waive any lawful right to bring a claim, file a complaint, or use a consumer-protection mechanism available to them.

39. Force Majeure

To the extent permitted by law, the developer will not be liable for delay or inability to provide the service caused by events outside the developer's reasonable control, including:

natural disasters;
war;
epidemics or pandemics;
widespread power outages;
telecommunications failures;
large-scale cyberattacks;
mandatory government actions;
serious failures of infrastructure providers;
disruption of distribution platforms by Apple or Google.

This provision does not exclude obligations that applicable law requires the developer to perform regardless of such circumstances.

40. Severability

If any provision of these Terms is determined by a competent authority to be invalid or unenforceable, the remaining provisions will continue in effect to the extent permitted by law.

The invalid provision will, where legally permitted, be interpreted or limited as closely as possible to its original purpose while remaining lawful.

41. No Waiver

If Loro does not immediately exercise a right or remedy under these Terms, this does not mean the developer permanently waives that right or remedy.

42. Entire Agreement

These Terms, together with the Privacy Policy and any applicable mandatory terms of an app store or related third-party service, form the main rules governing your use of Loro within their respective scope.

43. Language

Loro may provide these Terms in multiple languages for international users.

Translations should aim to reflect the same legal meaning.

If a difference arises because of translation and applicable law permits one version to be designated as the controlling or reference version, the version identified by Loro as the original or reference version will be used to interpret the Terms.

However, this provision does not limit mandatory consumer rights under local law.

44. Contact
