Calculation scope
The calculators and learning material provide estimates and mathematical references. A result is not an academic policy, medical diagnosis, financial offer or professional recommendation. Check the stated assumptions, units, rounding and sources, and confirm important decisions with the institution or professional responsible for them.
Inputs and local processing
Calculator inputs are processed in your browser. Do not enter passwords you already use, account credentials or unnecessary identifying information. Public-page analytics are separate from calculation inputs. See the privacy policy for page analytics and retention.
Privacy policyEmbedding a calculator
The embed code displays a calculator inside an iframe, either directly or through the optional loader script. Attribution is optional: its link uses nofollow and removing the attribution does not disable calculation. Keep limitations and input labels visible, do not present Toolify as endorsing your website, and do not frame the widget as a collection form for sensitive information.
Reasonable access and availability
Use the service without disrupting other visitors, bypassing access controls or misrepresenting the source of its content. Features may change as calculations and documentation are corrected. Offline tools remain a cached version until refreshed; verify time-sensitive rules and conversion assumptions independently.
Corrections and contact
If a calculation or explanation appears wrong, include the tool URL, non-sensitive sample inputs, expected result and the rule or source you used. Contact: binjia70@gmail.com
