Common Questions
Is my data sent to the cloud?
No. CsvTitan is a local-first desktop application. Your data never leaves your machine. We have zero visibility into your files.
How much does it cost?
We are currently in Beta. Early access users will receive a substantial discount on the lifetime license ($49) when we launch v1.0.
Does it support TSV and JSON?
Currently, CsvTitan is hyper-optimized for CSV files only. We are focused on perfecting the CSV experience before adding support for other formats like JSON or Parquet.
