Privacy without vague promises

Work on this device

Data Sparrow does not send file names, column headings, cell values, result details, or saved steps when work happens on this device. Preferences and saved steps can remain in this browser; table rows are not saved by default.

Online processing

Some file types and very large tasks may need secure online processing. Before an upload, you see the limits, deletion time, and what will happen. Your approval applies to that task only.

Temporary files

Uploads, working copies, and results are deleted after download, when you delete or cancel them, after an error, or when their short time limit ends. Data Sparrow has no accounts or permanent online file library.

Service records

Basic service records may note which tool ran, how long it took, a broad file-size range, or an error type. They do not contain file names, column names, values, saved steps, passwords, or file contents.

Local data controls

Clearing saved data removes preferences, saved steps, recent tools, and unfinished work from this browser. It cannot remove files you already downloaded.
