Terms and Conditions
§ 1 Scope
These terms and conditions govern the use of the web application Japanji ("Japanji") at the domain japanji.com. The provider is Sebastian Baier, contact: info@japanji.com (further details in the Imprint). Japanji is intended for private individuals who want to learn Japanese. By registering an account you agree to these terms.
§ 2 Conclusion of contract
The usage contract is concluded by registering an account and subsequently confirming the email address. Registration is free of charge.
§ 3 Services
Japanji provides tools for learning the Japanese writing system (kana, kanji) and vocabulary — in particular lessons, flashcard-based spaced repetition, stroke-order displays, mnemonic stories, and a progress dashboard. Operation is on a best-effort basis; there is no entitlement to any specific availability, scope of features, or response time. We reserve the right to change, limit, or discontinue individual features at any time.
§ 4 User obligations
Users agree not to misuse Japanji. In particular, the following are prohibited:
- automated content scraping (bots, crawlers) without prior written permission,
- circumventing technical protections (rate limits, access controls),
- infringing copyrights or trademarks when contributing your own content (e.g. community mnemonics),
- submitting unlawful, offensive, or third-party personal content,
- sharing your account access with others.
In the event of a violation, the account may be suspended or deleted without prior notice.
§ 5 Pricing and payment
Using Japanji is free of charge. Voluntary donations (where offered) create no entitlement to services and are not consideration under a paid contract.
§ 6 Liability
Because Japanji is offered free of charge, the provider's liability is limited to intent and gross negligence. For ordinary negligence the provider is liable only in the event of a breach of a material contractual obligation ("Kardinalpflicht"), and in that case limited to the typically foreseeable damage. Mandatory liability under the German Product Liability Act and for damages arising from injury to life, body, or health remains unaffected.
Japanji makes no claim as to the accuracy or completeness of its learning content. Language content (meanings, readings, mnemonics, example sentences) is sourced from various open datasets and from the community and may contain errors. Use at your own risk.
§ 7 Termination
You may terminate the usage contract at any time, without notice, by deleting your account via Settings → Delete account. This erases all associated data in accordance with the privacy policy. The provider may terminate the contract with reasonable notice or, in the event of a violation of § 4, without notice.
§ 8 Final provisions
The law of the Federal Republic of Germany applies, to the exclusion of the UN Convention on Contracts for the International Sale of Goods. Mandatory consumer-protection provisions of the user's country of habitual residence remain unaffected.
If individual provisions of these terms are or become invalid, the validity of the remaining provisions remains unaffected. The statutory rule applies in place of the invalid provision.
