By downloading, installing, or using Lumi ("the App"), you agree to be bound by these Terms of Use ("Terms"). If you do not agree, please do not use the App.
Lumi is a personal task and project assistant for iPhone and iPad. It lets you:
The App's language understanding runs entirely on your device. It does not use a remote AI service.
Lumi requires no account and no sign-up. The App contains no in-app purchases, no subscriptions, and no paid tiers. There is nothing to buy and no billing to manage.
Your tasks, projects, and conversations are stored on your device, and optionally in your own iCloud account if you enable sync. We do not receive them. You are the only party who can read or delete them. See the Privacy Policy for details.
Lumi reads what you type in order to file it — extracting a title, a date, a project, a recurrence rule. Its interpretation is automated and will sometimes be wrong.
You are responsible for reviewing what the App files, and for correcting it. Every action the App takes on your behalf can be undone from within the App. Please check items before acting on them.
You agree not to:
The App, including its software, design, and branding, is owned by Wandering Architect and protected by intellectual property laws. You are granted a limited, non-exclusive, non-transferable license to use it on Apple devices for your personal, non-commercial use, in accordance with the App Store Terms of Service.
The App integrates no third-party service. It does not call any remote API and contains no third-party AI, advertising, or analytics SDK. If you enable iCloud sync, Apple's iCloud service is involved, governed by Apple's Privacy Policy.
The App is provided on an "AS IS" and "AS AVAILABLE" basis, without warranties of any kind, either express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. Apple is not a party to these Terms. We do not warrant that:
To the fullest extent permitted by law, Wandering Architect is not liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of the App, including lost data, lost profits, or business interruption. In no event shall our liability exceed the amount you paid for the App, which is zero.
Nothing in these Terms limits rights you have under applicable consumer law in your jurisdiction.
You agree to indemnify Wandering Architect against any claim arising from your misuse of the App or breach of these Terms, to the extent permitted by law.
You may stop using the App at any time by deleting it from your device, which also deletes the local data. We may suspend or terminate access if you materially breach these Terms.
We may update these Terms. The "Last updated" date above will be revised and the new version posted on this page. Continued use after a change means you accept the updated Terms.
If any provision of these Terms is held unenforceable, the remaining provisions stay in effect.
These Terms are governed by the laws of the People's Republic of China, without regard to its conflict of law provisions. Mandatory consumer protections under the laws of your country of residence still apply where required.
