Privacy, by construction.

Replay Capsule is local-first software. The library makes no network requests and includes no analytics or tracking.

What the library records

Only after a user explicitly starts it, the library can record keyboard codes, normalized pointer positions, changed gamepad samples, timing, a developer-supplied seed, and developer-supplied checkpoints. It intentionally ignores events from text fields, textareas, selects, and editable content.

Where the data goes

Capsules remain in the current browser tab until the user downloads one. Replay Capsule does not upload, persist, sell, or share capsule data. A game developer who integrates the library controls what they do with a file after it is exported and should disclose any separate collection.

This documentation site

The live demo runs entirely in your browser. It uses no cookies, local storage, telemetry, advertising, or third-party runtime services. Server operators may retain short-lived standard request logs for reliability and abuse prevention.

Your control

Reloading the page clears the demo state. Downloaded capsules can be deleted like any local file. Do not include secrets or personal information in developer-supplied seeds or checkpoints.
