Frequently asked questions
About the Office Tools category.
What are FastSaveMedia Office Tools?
Office Tools is a free set of 17 browser-based work tools: a work hours and timesheet tracker, 13 HR, payroll, tax and investment calculators, a webcam and microphone test, and a sleep calculator. Everything runs locally in your browser at fastsavemedia.com/office-tools/.
Are the Office Tools really free?
Yes. Every Office Tool is free to use, with no signup, no install, no watermark and no usage limit.
Is my data uploaded anywhere?
No. Every Office Tool runs entirely in your browser. Timesheet entries, salary figures, camera and microphone streams never leave your device and are never sent to a server.
Which countries do the salary and tax calculators cover?
The salary tax estimator covers India, the United States and the United Kingdom. Gratuity and EPF follow Indian rules, while overtime defaults to the US 1.5x-after-40-hours rule and can be changed.
Do the tools work on a phone?
Yes, all of them are mobile-first. The webcam and microphone test additionally needs an HTTPS connection and camera permission, which every modern mobile browser supports.
The tools used to be at a different address. Are my bookmarks broken?
No. Every previous address now redirects permanently to its new /office-tools/ address, so old bookmarks and shared links keep working.
