Clear inputs
A tool should ask only for the information needed to do its job and label every field clearly.
Trust & methods
Know what a tool does before you rely on it.
A useful result should come with enough context to understand where it came from. These principles guide every collection in the AG Tools network.
Our operating principles
Visible assumptions
Calculators should state important assumptions, units, rounding, and limits near the result.
Local processing where practical
File and utility tools should process information in your browser when the task can be completed safely on your device.
No disguised certainty
Estimates are identified as estimates. Health and finance tools provide general information and do not replace qualified professional advice.
Corrections matter
When an error is reported, we review the method and update the explanation as well as the result when needed.
Different tools handle data differently
Some tools can work entirely in your browser. Others may eventually require a remote service to complete a task. Each live collection should explain its own processing model where you use the tool, because a general promise would be misleading.
Before using a sensitive file or entering personal information, read the privacy notice shown by that collection. Do not use a tool if its explanation does not give you enough confidence for the information involved.
Use results with judgment
Web tools can help you explore a question, prepare information, or check a calculation. They can also be affected by incomplete inputs, changing rules, and assumptions that do not match your situation.
For decisions involving health, money, law, safety, or another regulated field, confirm the result with a qualified professional or an authoritative source.
