Privacy policy
Effective June 10, 2026.
Flash Visualizer is designed so there is almost nothing to have a policy about. The short version: we do not collect your files, we do not have accounts, and we cannot see what you make.
Your audio and images
Files you load into the app are decoded, analyzed and rendered entirely inside your browser on your own device. They are never uploaded, transmitted or stored by us. Rendered videos are saved directly to your device by your browser.
Accounts and personal data
There are no accounts, no sign-up forms and no email collection anywhere on this site. We do not ask for, receive or store personal information.
Analytics
This site uses Cloudflare Web Analytics, a privacy-first measurement tool that does not use cookies, does not fingerprint devices and does not track you across sites. It tells us aggregate page views and nothing about you as an individual. Cloudflare also serves this site and, like any host, processes IP addresses transiently to deliver content and protect against abuse.
Cookies
We set no cookies. App settings live only in the page while it is open.
Changes and contact
If this policy ever changes (for example, if we add an optional feature that needs storage), this page will say so plainly. Questions: contact the operator, Charlestowne Marketing.
