Is anonymizing my CSV free?

Yes — you can anonymize pasted data with no signup; create a free account to process uploaded files.

What does it remove or replace?

It detects PII such as names, emails, phone numbers, SSNs, and card numbers, and either redacts or synthesizes them depending on the mode you choose.

Will the anonymized data still be usable?

In synthetic mode the structure and formats are preserved, so the result stays useful for testing and analytics without containing real identifiers.

Does it store my sensitive data?

Your input is processed only to produce your anonymized output and is not used to train AI models.

Most data you need to share contains something you should not expose: customer names, email addresses, phone numbers, account or card numbers. Sending the raw file to an agency, a contractor, or a test environment is a privacy and compliance risk — but manually find-and-replacing every identifier is slow and error-prone, and it is easy to miss a column.

The DatumFuse Anonymizer detects personal and sensitive information automatically and transforms it for you. Choose Redact to mask the values in place, or Synthetic to replace them with realistic fake data that keeps the same shape — so the file is still usable for testing and analytics, just without the real PII. Paste a sample to try it free, or sign in to anonymize a full file.
