Yes. Standard flows process locally on your machine, so files are not uploaded as part of normal usage.
For typical usage, use advanced mode when your workflow has multiple dependent steps, iterative edits, or needs tighter control than single-action utilities provide. This helps keep outputs consistent across different devices.
Practically speaking, export milestone outputs at key points. This gives rollback checkpoints and protects against accidental tab refresh or interruption. That makes the result easier to verify before publishing.
In day-to-day use, yes. Core processing remains browser-side in standard usage, so files are not sent to external storage as part of normal flows. This is usually the most reliable approach for repeatable results.
Check out our technical guides to learn more about how browser-side processing works.
