Effective date: 23 September 2026
These terms govern Arrival English. TECHTENSTEIN INC is the app operator and contracting entity. By using Arrival English after release, you agree to the final terms and the applicable app store terms.
Educational purpose
Arrival English provides practical phrase practice. It does not certify fluency, guarantee an outcome, provide legal, medical, immigration, financial or other professional advice, or replace a qualified interpreter. Check important information with the relevant organisation or professional.
Licence and acceptable use
We grant you a limited, personal, non-exclusive, non-transferable and revocable licence to use the app and bundled content. You may not resell, republish, distribute, scrape, bypass security, interfere with the service, or reverse engineer the app except where applicable law expressly permits it. Open-source components remain governed by their licences.
Learning data and offline packs
You are responsible for exported files and for reviewing a phrase’s context before relying on it. Signed offline lesson packs are validated before installation. Do not install files from an untrusted source. Content may be corrected or versioned to improve accuracy, safety or compatibility.
Advertising and purchases
The free app may display advertising after applicable privacy choices. Arrival English Ad-Free is a one-time, non-consumable purchase that removes in-app advertising on the store where it was bought. It is not a subscription. The free learning baseline remains available without purchase. Google Play and Galaxy Store purchases, restoration and refunds are handled separately; cross-store restoration is not promised.
Availability and changes
App, ad, store and third-party services may be unavailable or change. We may update the app for security, compatibility, policy compliance, content quality or new features. We will not intentionally remove local learning data without a clear user action or a reasonable migration path.
Warranty and liability
To the extent permitted by law, the app is provided “as is” and “as available.” We do not promise uninterrupted operation or that every phrase fits every situation. Nothing in these terms excludes rights or liability that cannot lawfully be excluded. Subject to those rights, TECHTENSTEIN INC is not liable for indirect or consequential loss arising from use of the app.
Governing law and contact
These terms are governed by the laws of India, without limiting mandatory consumer protections that apply where you live. Courts with jurisdiction in Bengaluru, India may hear disputes, subject to applicable law. Contact contact@mintback.app before filing a claim so we can try to resolve the issue.
