Alumo

Privacy Policy

Effective November 11, 2026

Alumo is an app for iPhone and iPad that controls LED lights you already own. It works on your device and on your home network. It has no user accounts and no server of its own, and it does not collect personal data.

In short: we do not collect, sell or share your data. Alumo has no ads, no analytics and no tracking. The data the app needs stays on your devices and in your own iCloud account.

Who we are

Alumo is developed by the developer named as the seller on the App Store. For any privacy question, write to support@alumo.io.

Data the app uses on your device

Bluetooth

Alumo uses Bluetooth to find and control LED controllers near you. It stores the names and identifiers of the lights you add, so it can connect to them again. This data stays on your device.

Local network

Alumo looks for Wi-Fi LED controllers on your home network and sends commands to them directly. Their network addresses stay on your device. The app does not send this traffic to the internet.

Microphone

Alumo uses the microphone only in music mode, and only after you allow it. The app analyses the sound in real time on your device to set the colour and brightness of your lights. It does not record, store or send any audio.

Your lights, groups and scenes

Alumo keeps your lights, groups, scenes and settings on your device. When iCloud is on, Apple syncs them between your iPhone and iPad through your private iCloud database. We cannot see or access this data. Apple's handling of iCloud data is described in the Apple Privacy Policy.

Siri, Shortcuts, widgets and Apple Watch

These features run on your devices and send commands to your lights the same way the app does.

Purchases

Alumo Pro is a one-time in-app purchase. Apple processes the payment. We do not receive your name, payment details or Apple Account information. We only learn from Apple that the purchase is valid, so the app can unlock Pro on your devices.

Crash reports

If you agree to share analytics with app developers in your device settings, Apple may send us anonymous crash reports and usage statistics. They do not identify you. You can turn this off in Settings > Privacy & Security > Analytics & Improvements.

When you write to us

If you email us, we receive your email address and what you write, including any attachments. We use them only to answer you. We do not add you to a mailing list. We delete the conversation when you ask us to.

What we do not do

We do not show ads.
We do not use third-party analytics or tracking.
We do not track you across apps or websites.
We do not sell or share your data.
We do not require an account.

Children

Alumo does not collect personal data from anyone, including children under 13 (or the age set by the law in your country).

Your rights

Depending on where you live (for example, under the GDPR in the EU and UK or the CCPA in California), you may have the right to access, correct or delete your personal data, and to complain to a data protection authority. The only personal data we may hold is the emails you send us. To use any of these rights, write to support@alumo.io.

To delete the data the app keeps, delete Alumo from your devices. To delete synced data, open Settings > [your name] > iCloud > Manage Account Storage, choose Alumo and delete its data.

If this policy changes, we will publish the new version on this page and update the date at the top.
