Plain-language overview
Privacy and local data
This page is a guide, not the policy. Read the Free privacy policy or Pro privacy policy for the complete disclosure.
Local-first does not mean “never uses a network”
Notebook code normally executes in your device’s browser engine or app WebView. SciREPL does not operate an account, advertising, analytics, crash-reporting, or notebook-storage server. Workbooks and virtual files use local app/browser storage unless you export or send them. Android may include Free app data in an operating-system backup according to your device and account settings; Pro disables Android app backup.
Network use can still occur when you choose features such as runtime/package downloads, the catalogue, notebook code that fetches a URL, a user-chosen export destination, or Pro AI and Remote tools.
Free edition
The Free edition has no integrated AI provider or Remote broker. Its optional transfers are primarily runtime/package/catalogue downloads, notebook-authored network requests, and exports you initiate.
Pro edition
Pro can send selected messages, notebook context, files, tool arguments/results, or terminal traffic to a provider or broker that you configure. The developer does not receive or proxy those requests. The selected third party handles transferred data under its own terms.
- The AI Assistant includes a bounded workbook preview with new direct messages and can send more through tools you permit.
- AI Prompt cells use an isolated one-shot request with the prompt and context you review; they do not include Assistant history or tool results.
- Remote and terminal features connect to a broker you choose and can expose broader data or a real shell according to your permissions.
Understand reviewed AI context and Remote/security controls before enabling them.
Deleting local data
In-app clear actions target specific stores and may intentionally retain preferences, caches, credentials, or a different conversation scope. Clearing Android app storage or uninstalling removes the on-device profile, but an Android backup of Free may remain or later restore data; manage that backup separately in Android or your account. Pro disables Android app backup. On Windows preview, quit and delete the edition’s application-data directory.
Credentials
API keys and broker tokens are stored locally for the connections you configure. Do not put credentials in notebook cells. Review provider-facing context and tool permissions before sending, and rotate a credential if you believe it was exposed.
