Agreement and scope
These Terms govern your use of the Sapilumen website, Android mobile application, knowledge base and related features and materials, collectively the "Services". The Services are made available under the Sapilumen brand by Sapilumen.
The Privacy Policy and Cookie Policy explain how data and browser-storage technologies are handled. By using the Services, you confirm that you have read and accept these Terms. If you do not agree, do not use the Services.
Eligibility and minors
You may use the Services if you have the legal capacity to enter into this agreement under applicable law. If a user is below the age at which they may consent independently in their country, the Services must be used with the permission and supervision of a parent or legal guardian.
The parent or legal guardian is responsible for deciding whether to provide access and for supervising that use.
Purpose and learning materials
The Services support independent language learning through theory, exercises, writing, audio, reference materials and progress tools. They are educational resources and are not a substitute for professional certification, official translation or specialist advice.
We review the content and correct reported issues, but we do not guarantee a particular proficiency level, study duration, examination result or complete absence of errors. You can report an issue at [email protected].
Purchases, subscriptions and refunds
If paid features become available, purchases and subscription management may be provided through Google Play. In that case, payment details are processed by the application store rather than Sapilumen. Before confirmation, Google Play displays the price, currency, billing period and any applicable automatic-renewal information.
Subscriptions are managed and cancelled through your Google Play account. Refunds are governed by the Google Play Terms of Service, the Google Play refund rules and mandatory law applicable to the purchaser. These Terms do not limit consumer rights that cannot lawfully be waived.
Local progress and backups
The current application does not require an account or cloud synchronisation. Learning progress and settings are stored locally on the device. Clearing application data, uninstalling the application, resetting the device or moving to another device may result in the loss of local progress.
You are responsible for device backups available to you. If accounts or cloud synchronisation are introduced later, the relevant rules and Privacy Policy will be updated before that feature is launched.
Acceptable use
The Services are provided for personal, lawful learning. You must not use them to break the law or infringe the rights of others, distribute malicious code, interfere with the website or application, bypass security controls, impersonate another person or perform large-scale automated collection that places an unreasonable load on the infrastructure.
You must not copy, publish, sell or distribute a substantial part of the materials or software without permission, except where the law expressly permits it. Interoperability research, reverse engineering and similar acts remain permitted only to the extent that applicable law does not allow them to be prohibited.
Support requests and feedback
When contacting support, provide only the information needed to answer your request. You confirm that you have the right to send any submitted materials and that they do not infringe another person's rights.
We may use suggestions and error reports to improve the Services. Personal data included in a request is handled under the Privacy Policy.
Intellectual property
Rights in the brand, design, software and original learning materials belong to the Sapilumen operator or the relevant rightsholders. Third-party components, fonts, audio and other materials are used under their respective licences and with required attribution.
You receive a limited, revocable, non-exclusive and non-transferable right to use the Services for personal, non-commercial learning. This does not transfer intellectual-property rights or permit you to create and distribute a copy of the Service.
Third-party services and links
The Services may link to Google Play, VOICEVOX and other external resources. Their content, availability, payments and data practices are governed by their own providers. A link does not mean that we control the external resource or accept responsibility for its actions.
Review the terms and privacy notice of a third-party service before using it.
Availability, updates and service changes
We may update learning materials, fix errors, revise the interface and add or remove features. Access may occasionally be interrupted by maintenance, technical faults, security requirements or the actions of a third-party platform.
Material changes to a paid feature will respect already acquired rights and mandatory law. We will try to provide advance notice of changes that significantly affect use of the Service.
Suspension and ending use
You may stop using the Services at any time by leaving the website and uninstalling the application. We may restrict access to the online parts of the Services where necessary for security, abuse prevention, legal compliance or to stop a material breach of these Terms.
Where a restriction follows a breach, we will use a proportionate measure where practical and respect mandatory user rights. Uninstalling the application also removes locally stored progress unless the device restores it from a backup.
Warranties
The Services are provided in the form available at the relevant time. To the extent permitted by law, we do not promise uninterrupted or completely error-free operation, compatibility with every device or a particular learning outcome.
Nothing in these Terms excludes statutory guarantees or consumer rights that cannot be restricted by agreement.
Limitation of liability
To the extent permitted by applicable law, the operator is not liable for indirect loss, lost profit or loss of local data caused by circumstances outside reasonable control or by the user's actions, including uninstalling the application or clearing its data.
This limitation does not apply to liability that the law does not allow to be excluded or limited, including liability for intentional misconduct, gross negligence, death or personal injury, or breach of mandatory consumer rights.
Changes to these Terms and severability
We may update these Terms when the Services, payment methods or legal requirements change. The current revision date appears at the top of the page. For material changes, we will try to provide a prominent notice before they take effect.
If one provision is invalid or unenforceable, the remaining provisions continue to apply. The operator may transfer its rights and obligations to a successor as part of a reorganisation or transfer of the project, subject to applicable law and user rights.
Applicable law, disputes and contact
These Terms are governed by the law applicable to the operator, without depriving a consumer of mandatory protection granted by the law of their habitual residence. The competent court and any available out-of-court procedure are determined by applicable law.
Before making a formal claim, please contact us so we can try to resolve the issue directly. Questions about these Terms can be sent to [email protected].
