Privacy Policy

Who we are

Lanteon is a screen-time app and this website, lanteon.app. You can contact us about anything in this policy.

What data we collect

On this website. If you join the waitlist, we store your email address and the date you signed up. We also run Umami, a self-hosted analytics tool, to see which pages people read. It collects page views, referrer URLs, browsers, operating systems, device types and country of origin. It does not use cookies, does not store IP addresses and does not track you across other websites.

In the Lanteon app. The app tracks time only on the apps you pick. It never tracks your whole phone. For the apps you track, we collect how much time you spent, per app per day, and send it to our server. It also stores the handle you pick and the list of people in your circle. The app does not read your messages, browsing history, contacts, location, or the content of anything you do on your phone. It only measures time.

How tracked apps are identified depends on your device. On Android, each tracked app is recorded by its package name (for example com.instagram.android). On iPhone, Apple does not tell us which apps you picked: we receive an approximate daily total for your tracked set under an anonymous id, and the app names your circle sees are the ones you type in yourself.

To run the app and keep your account safe, we also store some technical details: an id for each device you install the app on, a notification token if you turn notifications on, and, for each sign-in, the IP address and app or browser version it came from. We use these to sync your data, send the notifications you asked for, and protect your account. We do not use them to track you across other apps or websites.

Why we collect it

We use your email only to tell you when Lanteon ships, or for major updates.

We use your usage data for one purpose: accountability. Your circle, the people you chose, see how much time you spent on the apps you are trying to cut down. That is the product. We do not use it for advertising, profiling, or anything else.

We use analytics in aggregate to understand which pages people read.

How we store and share it

Your email is stored in Cloudflare KV. Analytics data is stored on a server in Germany (EEA).

Your per-app usage syncs to our server, and the server works out the summaries your circle sees. You choose how much that is: the full per-app breakdown, app names without numbers, or just the total. Nobody outside your circle can see your numbers. We do not sell your data, we do not share it with advertisers, data brokers, or any other third party, and there are no third-party ad or tracking SDKs in the app.

How long we keep it

Waitlist emails are kept until you unsubscribe. Usage data and your circle are kept while your account exists.

If you delete your account, we delete your usage data: every per-app usage record and the copies of your totals that your circle could see. Deletion removes what others could see of you, not just your own view. We keep nothing for research or analytics.

Your rights

Under UK GDPR, you have the right to:

• Leave the waitlist at any time on the unsubscribe page
• Access your data, email us and we will confirm what we have
• Delete your data, leaving the waitlist removes your email and deleting your account removes your app data
• Complain to the ICO if you are unhappy with how we have handled your data

Legal basis

We process your email and your usage data based on your consent: you give it when you join the waitlist or set up the app and choose your circle. You can withdraw it at any time by leaving the waitlist or deleting your account.

For analytics, the legal basis is our legitimate interest in understanding which pages people read. The analytics do not use cookies or process personal data, so no consent is required.

Changes

If we make significant changes to this policy, we will note it at the top. The current version was last updated on 8 July 2026.
