Read Guide →Never. TableMask is built on a 100% local-first architecture. All parsing, regular expressions, and masking happen directly inside your browser using Web Workers. You can literally disconnect your internet and the tool will work perfectly.
When you mask data, TableMask temporarily saves a secure token map (e.g., [NAME_1] = Sarah Chen) strictly inside your browser's temporary memory (RAM). When you paste the AI response back into the de-anonymize tab, it swaps tokens back to real values. Closing the browser tab wipes this map forever.
Yes. Since zero data is transmitted, processed, or stored on our infrastructure, using TableMask effectively stops data exposure before it even reaches OpenAI or Anthropic servers, keeping your workflows compliant.
We offer a bulletproof 14-day money-back guarantee through Paddle. If TableMask doesn't fit your workflow, just drop us an email and we'll refund 100% of your purchase.
