If your question is not covered here, please send a message. Useful feedback helps us improve the tools and the information around them.
Contact ZetTool →Do I need an account to use ZetTool?
No. The tools currently available on ZetTool can be used without creating an account.
Are ZetTool calculators free?
Yes. The calculators and utilities currently published on ZetTool are free to use.
Does ZetTool store what I enter?
Basic calculator inputs are used in your browser to create the result. The Online Notepad stores a note locally in your browser only after you save it. Please read our Privacy Policy for full details.
Can I rely on calculator results for important decisions?
Tools are intended for general planning and convenience. Check important financial, health, legal or official results against an appropriate professional or official source.
Why are some PDF or image features described as guides?
We only present a feature as a working tool when it is ready to use reliably. Where a full in-browser tool is not available, we provide transparent, practical guidance rather than an empty upload form.
How can I suggest a new tool?
Email mirzanayab18@gmail.com or use our contact page with your idea and how you would use the tool.
