Advertising cookies
Google AdSense and its partners use cookies to show ads, limit how often you see them, measure performance and, where permitted, personalise ads based on your visits to this and other websites. You can manage personalised ads in Google Ads Settings and learn more at Google's advertising policy page. Where the law requires it, you will be asked for consent before these cookies are used.
Embedded services
YouTube videos use privacy-enhanced mode and do not load until you press play. Google Fonts serves our typefaces. These services may log technical information when they load.
How to control cookies
You can block or delete cookies and site data in your browser settings. Blocking essential storage will stop the khata and invoice generator from saving your work. Clearing site data deletes your khata, so download a backup first.
