Practical guidance
- Keep a copy of the original dataset before transforming it.
- Spreadsheet applications can interpret some cell values as formulas; review untrusted downloaded CSV before opening it.
Privacy & processing
Tools described as browser-local process the working input in your browser and do not intentionally upload that tool input to AllStoic for processing. Normal hosting, security and network infrastructure may still process ordinary connection metadata needed to deliver and protect the site. Check the individual tool guidance before use.
