Data and privacy
Free tools process files and calculations in your browser. We do not ask you to send your source data to the creator.
Work data
CSV files are processed in browser memory. Local editors may save workspaces in your browser storage; this is not a backup or cloud sync. Download JSON copies and review outputs before sharing them.
Website and links
The site is hosted on GitHub Pages. Purchases and messages use Boosty, and updates use Telegram; those services have their own data policies. External links may contain UTM parameters for the tool and link placement. These never include files or calculation values.
Usage events
The storefront and its online Extra Work and CSV Preflight tools send only a schema version, action name, product name, button placement and language to the event receiver. The service stores aggregate counts by UTC day. The analytics code does not create cookies or persistent browser identifiers and sends no URLs, referrers, UTM parameters, case text, file names, file contents or calculation values. Network infrastructure may process connection metadata.
Counts represent page views and button presses. They do not represent unique visitors, payments or confirmed downloads and shares. Repeated views and presses may be counted again.
The free technical case editor makes no network requests. The storefront records only clicks on links to the editor; actions inside it and case text are not collected. Downloaded local versions of the tools also run without central analytics.
