Privacy policy
Last updated: 19 August 2026
Lumo collects nothing. There is no account, no Lumo server, no analytics and no advertising: the app talks to your display on your local network, and to nobody else.
What Lumo reads on your device
Every source starts switched off and asks for its permission the first time you switch it on. You can withdraw it at any moment in your system settings.
- Activity (Health)
- Show your steps, calories, distance and exercise minutes for the day on the matrix.
- Calendar
- Show the title and time of your next event.
- Reminders
- Show how many reminders you have left today.
- Contacts
- Show today's birthdays.
- Focus mode
- Signal on the display that you are focusing.
- HomeKit sensors
- Show the temperature and humidity of your home.
- Local network
- Find your display and talk to it.
This data is read at display time and is not kept: Lumo holds the last shown value in memory, until the next one arrives. It goes straight to your display, on your local network.
What Lumo stores
On your device only: your settings (known displays, enabled sources, scenes, alerts) in the app's preferences, and your API keys in the system Keychain — never in the preferences, never synchronised, never backed up elsewhere. Uninstalling Lumo erases both.
The services you connect yourself
A connector calls the API you point it at. Those requests go from your device to that service, without passing through Lumo, and are subject to that service's own privacy policy. Lumo keeps only the value it shows. The sources on by default call nothing but the public Open-Meteo weather API, with no key and no account.
Health data
Apple governs the use of health data specifically, and Lumo abides by it: it serves only the display you asked for on your device. It is never passed to a third party, never used for advertising or marketing research, and never kept beyond the value being shown.
Your rights, and reaching us
Since nothing leaves your device, we hold no data for you to consult, export or have erased. You keep control of everything: the permissions in your system settings, the keys in the app, the rest by uninstalling it. A question? Write to contact@playfan.fr.
