Why there's a daily download limit (and why it doesn't need an account)

Davix has no accounts, no login, and no tracking of who you are. But it does have a daily download limit. Those two facts aren't in tension — the limit exists to keep the service healthy for everyone, not to gate features behind a paywall.

Every download consumes real compute and bandwidth. Without some ceiling, a handful of scripted requests could exhaust resources for every other visitor. So each anonymous visitor gets a modest number of downloads per day, reset at midnight UTC.

To enforce that without accounts, Davix derives a short-lived, salted hash from your connection's network identity and a counter in Redis — never your raw IP address, and never anything that persists beyond a day or that we could hand over to identify you personally.

Analyzing a link — seeing its title, thumbnail, and available formats — never counts against the limit. Only a completed download does. That way you're always free to check what a link contains before deciding whether it's worth spending part of your daily allowance.
