JReader Terms of Service
These Terms of Service ("Terms") govern your use of JReader (the "App"), published by Greycastle ("we", "us"). By installing or using the App you agree to these Terms. If you do not agree, please do not use the App.
Using the App
JReader lets you read native Japanese articles, look up words, save vocabulary, and listen to article audio. You must provide your own device, internet connection, and any store account needed to install the App, and you are responsible for keeping your device and account secure.
Accounts
An account is optional. If you create one, keep your login details confidential and tell us straight away if you believe someone else has access to it. You are responsible for activity that happens under your account. You can delete your account at any time from within the App or by emailing david@greycastle.se.
Costs, purchases and subscriptions
The App is free to download and use. If we introduce paid features, purchases are handled by the Apple App Store or Google Play, and the store's own payment, refund, and subscription terms apply to those purchases.
- Subscriptions are billed in advance and renew automatically until you cancel.
- You can cancel or change a subscription at any time in your App Store or Google Play account settings; cancelling stops future charges but does not refund the current period.
- Prices may change. We will tell you before a change affects a subscription you already hold.
- Refunds are handled by Apple and Google under their policies.
Acceptable use
You agree not to:
- copy, resell, or redistribute the App or the articles it shows in bulk;
- scrape, crawl, or automate access to the App or its content beyond what a normal reader does;
- reverse engineer, decompile, or try to extract the App's source code, except where this is allowed by law;
- upload unlawful, harmful, or infringing material, or use the App in a way that breaks applicable law or the rules of the store you installed it from.
Content and your data
The articles in the App are original content created by Greycastle AB, which owns the copyright and the exclusive publishing rights to them. Reading them for your own learning is fine; republishing, copying them in bulk, or redistributing them is not.
Vocabulary lists, notes, bookmarks, and reading progress you create belong to you. You keep those rights, and you can export or delete them from within the App. We only use them to give you the features you asked for, as described in our privacy policy.
Third-party services
The App relies on services we do not control, including Apple and Google platform services for distribution and account sign-in, and third-party text-to-speech providers for article audio. Their terms may apply alongside these Terms.
Beta features
Some features are offered in beta. Beta features may change, be limited, or be withdrawn without notice, and may not work as well as the rest of the App. Using them is optional, and these Terms still apply to them.
Changes to the App and to these Terms
We may add, change, or remove features, and we may update these Terms. When a change matters, we will point to the new version here and in the App. Continuing to use the App after a change takes effect means you accept the updated Terms.
Ending your use
You can stop using the App at any time by deleting it and, if you have one, deleting your account. We may suspend or end access if you break these Terms. Where it is reasonable to do so, we will tell you why.
Disclaimers
The App is provided "as is", without warranties of any kind, to the extent allowed by law. We work to keep it reliable, but we do not promise it will be uninterrupted or error-free. Articles are shown for language learning; they are not professional, legal, medical, or financial advice.
Liability
We are liable only to the extent required by applicable law. Nothing in these Terms limits your statutory rights as a consumer, and nothing excludes liability for death, personal injury, fraud, or anything else that cannot lawfully be excluded.
Governing law
These Terms are governed by Swedish law. If you live in the EU, the mandatory consumer protection rules of your country of residence continue to apply, and you may also use the European Commission's online dispute resolution platform.
