Specific answers for teams replacing Deepnote with IpynbCellShield.
Jupyter stores historical stdout logs, exception tracebacks, and rendered HTML DataFrames inside cells[].outputs and widget metadata. Even if you delete an API key from a code cell, it often remains cached inside the JSON output array.
nbstripout wipes 100% of your cell outputs, destroying the very charts, evaluation metrics, and error tracebacks you want teammates or Claude/ChatGPT to review. IpynbCellShield keeps the outputs intact while masking only the secrets and PII.
An .ipynb file is a deeply nested JSON document where Python code and HTML tables are stored as JSON-escaped string arrays. Naive sed replacements corrupt escaped quotes (\") and render the notebook unreadable by JupyterLab.
Yes. It scans both text/plain and text/html execute_result payloads to mask email addresses, phone numbers, internal IPs, and bearer tokens while keeping DataFrame column headers and shapes intact.
Never. All nbformat JSON parsing, regex/AST scrubbing, and Canvas preview rendering run 100% locally in your browser RAM with zero network egress.
The €3.99 24h Pass unlocks 100% unblurred .ipynb export in your current browser for 24 hours. The $19 Offline PRO Workstation delivers a standalone, zero-network HTML file for permanent air-gapped data science use.
