Legal
Last updated: June 2, 2026 · Effective immediately upon use of the Lumino extension or web app.
Lumino (“Lumino,” “we,” “us,” or “our”) is a screentime management service consisting of a Chrome browser extension and an accompanying web application. Together these tools help users set limits on the time they spend on specific websites, track their usage over time, and build healthier browsing habits through an in-app credit-score system.
This Privacy Policy describes how we collect, use, store, and protect information when you use Lumino’s Chrome extension and web application (collectively, the “Service”). By installing the extension or signing into the web app you agree to this policy.
For questions or concerns, contact us at: lumino.team@outlook.com
We collect the minimum data necessary to provide the Service.
When you sign in with Google OAuth we receive your email address and a unique Google account identifier. We use this solely to create and authenticate your Lumino account. We do not receive or store your Google password.
The Chrome extension monitors the time you spend on websites that belong to a screentime group you have configured. Specifically, we record:
We do not record page titles, full URLs, search queries, form inputs, passwords, cookies, or any page content. We only know which top-level domain you visited and for how long.
We store the website groups and time limits you create so they can be synced to the extension and enforced consistently across sessions.
Lumino computes an in-app “credit score” based on how consistently you stay within your self-set limits. This score is stored in your account and displayed only on your personal dashboard. It is never visible to other users or any external party.
We store your browser’s local timezone so that daily limits reset at midnight in your local time rather than in UTC.
Our infrastructure provider may temporarily retain standard server logs (IP address, request timestamps, HTTP status codes) for security and reliability purposes. These are not linked to your browsing activity data and are purged within 30 days.
Every piece of data we collect is used for one purpose: making Lumino work for you.
Enforcing your limits
The extension reads your stored limits to determine when to block or warn you on a tracked website.
Populating your dashboard
Usage data is displayed in charts on your personal dashboard so you can see how you’re doing over time.
Computing your credit score
Your adherence to limits is calculated server-side and stored as a single numeric score shown only to you.
Resetting daily counters
We use your timezone to reset usage minutes at the correct local midnight.
Authentication
Your email is used to identify your account and let you sign in.
We do not use your data for advertising, analytics sold to third parties, machine-learning model training (beyond your own account), or any purpose not listed above.
We do not sell, rent, license, or share your personal data with any third party — including advertisers, data brokers, research firms, or other users of Lumino.
We use the following sub-processors solely to operate the Service:
Supabase
Managed PostgreSQL database and authentication. Your usage data and account information is stored here. Supabase operates on AWS infrastructure with encryption at rest and in transit.
Vercel
Hosting for the Lumino web application. Vercel processes requests but does not have access to your stored personal data.
Google OAuth
Authentication only. Google provides us with your email address when you sign in. We do not receive any other Google account data.
We may disclose information if required to do so by law or in the good-faith belief that such disclosure is necessary to comply with a legal obligation, protect our legal rights, or prevent harm. We will notify you of any such disclosure where legally permitted.
We take the security of your data seriously and implement the following protections:
While we implement these safeguards, no system is completely immune to security risks. If you discover a vulnerability, please disclose it responsibly to lumino.team@outlook.com.
We retain your data for as long as your account is active. Specifically:
When you delete your account all rows associated with your user ID are permanently deleted from our database within 7 days. Residual copies in automated database backups are purged on a rolling 30-day cycle.
You have the following rights with respect to your personal data:
Access
Request a copy of all data we hold about you.
Correction
Ask us to correct inaccurate data.
Deletion
Request permanent deletion of your account and all associated data.
Portability
Request your usage data in a machine-readable format.
Restriction
Ask us to stop processing your data in certain ways.
Objection
Object to any processing you believe is not justified.
To exercise any of these rights, email us at lumino.team@outlook.com. We will respond within 30 days.
Lumino is not directed at children under the age of 13. We do not knowingly collect personal information from children. If you believe a child has provided us with personal data, please contact us and we will delete it promptly.
The Lumino Chrome extension requests the following browser permissions, each of which is necessary for core functionality:
tabs
Required to detect which website is currently active in order to track time and enforce limits.
storage
Used to cache your limits and session tokens locally so the extension works without a network round-trip on every tab change.
alarms
Powers the timer that periodically saves your accumulated usage to our servers.
host permissions (matched domains)
Allows the extension to communicate with Lumino’s API (lumino-landing-livid.vercel.app) to read your limits and write usage data.
The extension does not use remote code execution, inject scripts on arbitrary pages, or access page content, form data, or cookies. Permissions are scoped to the minimum required and will not change without a policy update and new extension version.
By installing the Lumino Chrome extension or using the Lumino web application you agree to be bound by these Terms. If you do not agree, do not use the Service.
You may use Lumino for your own personal, non-commercial screentime management. You agree not to:
Lumino is provided “as is.” We do not guarantee uninterrupted access and may modify or discontinue features at any time. We are not liable for lost usage data resulting from service outages or bugs.
To the maximum extent permitted by law, Lumino shall not be liable for any indirect, incidental, special, or consequential damages arising from your use of or inability to use the Service.
These Terms are governed by and construed in accordance with the laws of the United States, without regard to conflict-of-law principles.
We may update this Privacy Policy from time to time. When we do, we will revise the “Last updated” date at the top of this page and, for material changes, notify you by email or via a notice in the web application. Continued use of the Service after any change constitutes your acceptance of the updated policy.
