Privacy Policy

Last updated: 2026-09-11

I believe in collecting the minimum necessary data to make the product work and improve responsibly. To that end, my current apps collect zero data and have no way of doing so. If you have questions, contact support@appsbymatt.ai.

Data We Collect

Account/contact info you choose to provide when requesting support.
Crash and diagnostic data to ensure stability (only enabled on testflight).

How We Use Data

I currently don't and do not plan to

Third‑Party Services

We may use privacy‑respecting analytics and crash reporting
For the on‑site chat widget, we use a third‑party provider
Messages you send via the widget are processed to deliver support

Data Retention

I'm not collecting any data soooo nothing to retain!

Your Choices

I'll update here and in the app listings if anything ever changes

Lumi

Lumi is designed with a strong privacy posture
AI runs on your device by default. If you enable Lumi Link, the text context needed for a reply is sent to your paired Mac.
Cloud features if ever added will be optional and disclosed in‑app with no intent to acquire data

Lumi Link

Both Mac editions accept requests from devices you pair. Text context is sent to the model runtime on your Mac for a reply; screen sharing sends the selected Mac display to your paired Vision Pro. Screen Recording and Local Network permissions enable these features.

Pairing credentials are stored locally. The optional conversation viewer on the Mac keeps entries in memory until you quit. Remote connections can use your own Tailscale network. Model downloads, support requests, and optional online tools use their respective services.

Lumiverse

Lumiverse can run Lumi on the headset or send the context needed for an AI reply to your paired Mac through Lumi Link. Mac display streaming is optional and requires permission on the Mac. Your conversations remain on the headset when you switch Mac editions.

Cosmic Sleep

Cosmic Sleep stores logs and schedules locally on your device
Apple's CloudKit handles syncing and sharing between user profiles and devices
Optional location services are used solely to offer automatic time zone updates while traveling, and this data is never collected or stored remotely
We do not have access to your personal sleep data

Lumi Widget operates with Shadow DOM isolation for privacy protection
No data is collected or transmitted by the widget itself
Chat interactions are handled by the hosting website's own systems
