Privacy policy

Sine uses Clerk for account sign-in and authentication. Clerk may process account identifiers such as your email address and sign-in provider details so Sine can keep your account secure.

Sine stores the account identifiers needed to connect your signed-in account to your Sine library and shared captures.

Audio files you upload, generated stems, shared capture assets, and related media files are stored in Cloudflare R2. Sine stores library, capture, render, and processing metadata in Convex so the web app and iPhone app can read the same product state.

Shared capture links are public to anyone with the link. Private library items stay tied to your signed-in account unless you choose to share them.

Sine may record basic product analytics, diagnostics, and server logs to keep the service reliable, investigate errors, and improve the upload, playback, and restore paths.

Sine does not sell personal information. Service providers are used only to operate authentication, storage, backend state, diagnostics, and product delivery.
