Question 1

Is Flex free?

Accepted Answer

Yes, completely free. No subscription, no hidden fees, no ads.

Question 2

How does the media library work?

Accepted Answer

Point Flex at your folders and it scans your collection automatically. It recognizes 15+ video formats including MKV, MP4, AVI, and MOV, then analyzes each file for codec, resolution, HDR, and audio tracks in the background. New and modified files are picked up on the fly.

Question 3

Can I stream to any device?

Accepted Answer

Flex transcodes on the fly using hardware acceleration (VideoToolbox, NVENC, VAAPI, QSV) so playback is smooth even on less powerful clients. Compatible files are served directly with zero re-encoding. Cast to Chromecast, AirPlay, or DLNA devices straight from the app.

Question 4

Can multiple people watch at the same time?

Accepted Answer

Yes. Each stream is an independent session with no artificial cap. The only limit is your hardware. Flex handles concurrent viewers out of the box.

Question 5

Is my watch progress tracked?

Accepted Answer

Watch progress is stored locally on your device by default. If you create an account, you can opt in to sync it across devices. Sync is never automatic — you choose when and what to share.

Question 6

What data does Flex collect?

Accepted Answer

Minimal, and only with your explicit consent. Analytics are opt-in and fully anonymized. Your viewing history stays on your device unless you enable sync. Flex never sells or shares your data.

Question 7

What can plugins do?

Accepted Answer

Plugins extend Flex with new content sources, subtitle providers, casting targets, and more. Each plugin declares its capabilities upfront so you always know what it can access.
