Terms of Use
Updated September 30, 2026
Use of tools
You may use these free browser tools for ordinary personal and professional tasks. You are responsible for checking inputs, choosing the right units and reviewing the stated method. Tools are not medical, legal or investment advice.
Results and availability
Calculations may be rounded, text counts may differ between systems, and availability is not guaranteed. An age result is a calendar calculation, not a legal eligibility decision. Fuel prices are examples or user-entered values, not live quotes.
Acceptable use
Do not interfere with the service, attempt unauthorized access, create fake usage or abuse the measurement endpoint. Do not submit data you are not entitled to process.
Passwords and QR codes
Store generated passwords securely; this service cannot recover them. Confirm QR contents and scan a downloaded code before printing or sharing it. QR links may lead to external sites for which you are responsible.
Updates
These terms may change as the service develops. Updated terms will appear here. No subscription or paid contract is created by using a calculator.
