Privacy Policy
Matrix: AI LED does not collect personal data, has no accounts, and shows no ads. Last updated August 9, 2026.
What stays on your device
Your saved artworks — their titles, the generated display scripts, thumbnails, and grid sizes — are stored only on your device, in the app's own storage. They are never uploaded to us. Deleting the app deletes them.
What is sent when you create with AI
The AI creation feature is the only part of the app that talks to a network. When you send a message in it, these are transmitted to our server and forwarded to our model provider, OpenRouter, so a display script can be written:
- the text of your message and the earlier messages in that conversation;
- the dot-matrix size and orientation your device is using;
- your app's display language, so the reply is written in it.
No name, email, account, device identifier, advertising identifier, contacts, photos, or location is attached to that request — we do not ask for them and the app does not have access to them.
We do not store your conversations on our server. Requests pass through it and the reply is returned to your device. Our provider processes the request under its own terms; see OpenRouter's privacy policy. Transient server logs may record ordinary technical information such as error codes and timestamps, used only to keep the service running.
What we do not do
- No analytics, tracking, or profiling SDKs are in the app.
- No advertising, and no data is sold or shared with data brokers.
- No cross-app or cross-site tracking.
Children
The app is suitable for all ages and collects nothing, so it holds no personal information about children or anyone else.
Purchases
Payment is handled entirely by Apple through the App Store. We never see your payment details; the app only learns whether a purchase exists.
Your rights
Because we hold no personal data about you, there is nothing for us to export or erase on request. Your artworks are yours to delete at any time inside the app.
Changes
If this policy changes, the updated version will be posted on this page with a new date above.
