Privacy Policy

Your files

Files you open in FastSub AI are processed inside your browser. They are never uploaded to us or to anyone else.

AI models

AI tools download model files from Hugging Face or jsDelivr the first time you use them. These requests contain no data from your files.

Local storage

The subtitle editor saves an autosave draft in your browser's local storage so you don't lose work. You can clear it any time from your browser settings. It also remembers the language you pick, and AI models stay in the browser cache so they download only once. FastSub AI sets no cookies.

Analytics

We count page views with Cloudflare Web Analytics, which uses no cookies, doesn't fingerprint your browser and doesn't follow you across sites. It only sees the page address, referrer, country and browser type, never your files.
