Privacy Policy

Effective 1 November 2026

Publisher details updated 4 November 2026

Lmiere is built to need as little of your data as possible. You can use the free lessons, review and practice without an account. Sign-in is needed for a free trial or subscription and lets your progress sync between devices. There are no ads, and we never sell or rent your data.

Who we are

Lmiere (the iPhone app and the website at lmiere.app) is published by Altus Lumen Ltd (“we”, “us”), company number 17331447. Altus Lumen Ltd is the controller of the personal data described in this policy; its registered office is under Contact. You can reach us at any time at support@lmiere.app.

The short version

What stays on your device

To make the app work, Lmiere saves the following in the app’s private storage on your iPhone:

If you don’t sign in, this information never leaves your iPhone and we cannot see it. It may be included in your own iCloud or computer backups of your iPhone, which Apple or you control. Deleting the app removes it.

Your account and sync

You need an account to start the free trial or a subscription; before that, signing in is optional. You sign in with Apple, with Google, or with your email address and a one-time code we email you; there is no password.

Your sign-in identity is held by our sign-in provider, WorkOS (United States): your email address (or the private relay address Apple gives us if you choose to hide yours), your name if Apple or Google shares it, a user ID, and records of your sign-ins.

In our own database we store, linked to that user ID:

We use this only to keep your progress safe and in sync between your devices, and to improve the course. It is stored with our database provider in the European Union (Frankfurt). Recordings of your voice, your name as Glim says it, and payment details are never part of your account.

You can delete your account at any time in Settings › Account › Delete account. That deletes everything stored with it from our database and deletes your sign-in identity at WorkOS straight away. If you never sign in, none of this is collected.

Subscriptions and payments

Lmiere Premium is sold as an in-app subscription through Apple’s App Store. Apple processes the payment under its own privacy policy, and we never receive your name, card or bank details from Apple. Apple tells the app whether a subscription or free trial is active.

The app checks your purchases directly with Apple on your iPhone (StoreKit). We do not use a third-party subscription service, and no receipt is sent to us. So that a subscription follows your account, the app attaches a random identifier derived from your user ID to your purchase; it tells Apple nothing about who you are. Restoring purchases on another device asks Apple, using your Apple ID.

Reminders

If you turn on the daily reminder, iOS asks for your permission first. The reminder is a local notification scheduled on your iPhone itself; no notification token or schedule is sent to us. You can turn it off in Lmiere’s Settings or in your iPhone’s Settings › Notifications at any time.

Sound and voice

Words and phrases are played from recordings bundled in the app or read aloud by your iPhone’s built-in speech system.

Speaking practice uses the microphone, and iOS asks your permission the first time. When you record yourself, the recording is kept in the app’s temporary storage on your iPhone so you can play it back next to the model voice. It is never uploaded to us or anyone else, and it is discarded when you move on. Lmiere does not ask for access to your contacts, photos or location.

When you contact us

If you email us, we receive your email address and whatever you choose to include in your message. We use it only to answer you and to fix what you report.

What we never do

Lmiere does not currently use third-party analytics. If we add privacy-respecting diagnostics, such as crash reports, we will update this policy before they are switched on. Separately, if you have chosen to share analytics with developers in your iPhone’s settings, Apple may give us anonymous crash reports and usage statistics.

This website

lmiere.app uses no cookies, no analytics and no third-party trackers, and its fonts are served from our own domain. The website is shown in a light appearance. Motion preferences are applied on your device and are not sent to us.

Like any website, our hosting provider automatically processes technical request data (such as IP address, browser type and the page requested) to deliver the site and protect it from abuse. These logs are kept for a short period by the hosting provider.

Service providers

We rely on a small number of providers who process data only on our instructions and under contracts that protect it:

We may also disclose data if the law requires it, or to protect the rights and safety of our users or of Altus Lumen Ltd. If Lmiere is ever transferred to another company, this policy will continue to apply to the data transferred, and we will tell you beforehand.

Legal bases

If you are in the European Economic Area, the United Kingdom or Switzerland, we rely on these legal bases:

How long we keep data

International transfers

Our providers may process data outside your country, including in the United States. Where data from the EEA, the UK or Switzerland is transferred to a country without an adequacy decision, we rely on safeguards such as the European Commission’s Standard Contractual Clauses or the EU–US Data Privacy Framework.

Your rights

Depending on where you live, you have the right to access your data, correct it, delete it, receive a copy in a portable format, restrict or object to its processing, and withdraw consent at any time. California residents also have the right to know what we collect and to not be discriminated against for using their rights; we do not sell or share personal information.

To use any of these rights, write to support@lmiere.app. We reply within one month. Without an account, your learning data is only on your own iPhone, so you already hold it, and deleting the app removes it. With an account, you can delete it all yourself in Settings › Account, or ask us for a copy. You also have the right to complain to the data protection authority where you live or work.

Children

Lmiere is not directed at children under 13, or under the minimum age for consenting to online services in your country, and we do not knowingly collect personal data from them. If you believe a child has sent us personal data, for example in a support email, contact us and we will delete it.

Security

Your progress stays in the app’s private storage on your iPhone, protected by iOS. If you sign in, your account data is encrypted in transit and at rest and protected so that each account can only read its own rows. Purchase checks with Apple are encrypted in transit, and support email is kept with access limited to the people who answer it. No system is perfectly secure, so if we ever learn of a breach that affects you, we will tell you and the relevant authorities as the law requires.

Changes to this policy

We will update this page when Lmiere changes the way it handles data, and change the date at the top. If a change is significant, we will tell you in the app before it takes effect.
