DemoVexa

Privacy and your data

What DemoVexa keeps on your computer, what it sends to Claude and ElevenLabs, where your keys live, and how to move your data folder.

DemoVexa runs on your own computer. Your projects, voiceovers and videos stay there, and only what's needed to write and voice a video is sent to the AI services you connect. This page explains what goes where.

#What stays on your computer

Everything DemoVexa makes is stored on your computer:

  • Your projects: briefs, scripts, scene plans, posts and covers.
  • Voiceovers, uploaded photos and clips, and rendered videos.
  • The database, your preferences and your backups.

Your app's code folder stays where it is. DemoVexa only reads it; nothing in the folder is changed. Rendering happens on your computer too.

#What's sent, and to whom

Sent toWhatWhy
Claude (Anthropic)The relevant parts of your app's code and docs, and the project it's working on, such as your brief and scriptTo plan, write and build your videos
ElevenLabsThe script textTo make the voiceover
Your product's websiteA normal visit to the public siteOnly when you use Import → From the website in a workspace's Brand tab, to fetch your logo, colours and fonts

For an Event Recap, Claude also looks at your photos and clips to build the storyboard.

Claude is reached through your own Claude login or Anthropic API key, and ElevenLabs through your own API key.

Note

With My Claude login, Claude can read your app's code while it writes the brief. With an API key it works from your how-to guides. Either way, the build itself reads your code to recreate the screens.

#Your DemoVexa account

Your online account at app.demovexa.com stores your account details, your plan and your usage: a record of the videos and renders you make, so it can count them against your allowance. Your code, scripts, voiceovers and videos aren't stored there.

#Where your keys are kept

Your Claude and ElevenLabs keys are stored in your operating system's password store, under the name "DemoVexa":

SystemPassword store
macOSKeychain
WindowsCredential Manager
LinuxThe keyring (Secret Service)

If the computer has no password store, DemoVexa keeps the keys in a private file in the data folder that only your user account can read.

Keys are only sent to Anthropic and ElevenLabs, and the app never shows them in full again after you save them. The studio's keys are shared by every workspace; a workspace with its own keys keeps them separately and uses them first.

Your preferences, such as how Claude runs, the model and the default voice, are saved in a settings file in the data folder.

#The data folder

The data folder holds everything DemoVexa makes. By default it's studio/storage inside the DemoVexa folder. It contains:

  • The database (your workspaces, projects, scripts and so on)
  • Uploads
  • Voiceovers
  • Renders
  • Covers
  • Stills
  • Logs
  • Your preferences
  • Backups

The code and audio for each animated video are written into the DemoVexa folder itself, alongside the data folder.

To open the folder, go to Settings → Database and click Show in folder.

#Move the data folder

You can keep the data folder somewhere else, for example on a larger drive, by setting STUDIO_DATA_DIR.

  1. Stop DemoVexa. In the DemoVexa folder, run ./run.sh --stop on macOS or Linux, or .\run.ps1 -Stop in PowerShell on Windows.

  2. Copy the data folder to its new location.

  3. Set STUDIO_DATA_DIR to the new folder's full path in the studio's settings file, studio/.env. For example:

    STUDIO_DATA_DIR=/Volumes/Media/DemoVexa-data

  4. Start DemoVexa again.

  5. Check Settings → Database to confirm the new location and Settings → Folder access to confirm it can write there.

Watch out

Make sure no builds, renders or batches are running before you move the folder. They keep going after the studio stops.

#Sharing the studio with a password

DemoVexa only listens on your own computer, so nobody else on your network can open it. If you set it up to be reachable by others, protect it with a password by setting STUDIO_PASSWORD. Visitors then see Sign in to DemoVexa and need the password to get in.
