Yes. Enable the Unique toggle in Numbers mode to ensure no duplicates.

What dice types are supported?

Standard tabletop dice: d4, d6, d8, d10, d12, d20, d100, plus custom sides.

Is any data sent to a server?

No. All random generation happens entirely in your browser.

ranges, roll polyhedral dice (d4 through d100), flip coins with streak

tracking, pick random items from a list, or draw lottery numbers with

popular presets. Enable the cryptographic option for security-grade
