We use local storage, not tracking cookies. Most data stays in your browser, not on advertising networks.
Essential storage keeps you logged in. Without it, you'd have to sign in every time.
Analytics are optional. You can opt out and still use Parleva fully.
You're in control. Clear your browser data anytime to remove all stored information.
