Privacy
Short version: this tool does not collect your data.
Your settings stay in your browser
Your chosen options (operations, range, count) are saved only in your own browser's local storage so the tool remembers your last setup. Nothing is sent to a server, saved to a database, or shared.
What we collect
We may use privacy-friendly, cookieless analytics that count visits without identifying you. We do not run intrusive ads or sell data, and there is no account or email required to use the tool.
Changes
If features that handle personal information are ever added, this page will be updated to describe them before they go live.
