本地工具处理

Tools explicitly described as local perform their calculations, conversions or file processing in the browser. Tool inputs are not sent to a HandyGrid application server. Page delivery, consent, advertising and optional analytics still use third-party infrastructure that may receive ordinary request, browser, device and consent data as described in the Privacy and Cookie Policies.

Publication and editorial responsibility

Goldwave Dynamics Limited is responsible for publishing and maintaining HandyGrid's original Tool descriptions, examples, methodology notes and policy pages. The Website does not attribute work to an unverified editor, reviewer, professional qualification or accreditation.

Calculation and Tool review

Calculation logic is kept separate from page presentation where practicable and is reviewed through strict type checking, unit tests, browser tests and a production release gate. Selected higher-value Tool pages identify their method, assumptions, limitations, test evidence, sources and latest internal review date.

An internal software review is not an independent audit, professional certification or guarantee. Important decisions still require verification against current authoritative sources or an appropriately qualified professional.

Sources and review dates

Where a Tool depends on an external technical convention, selected pages link to the relevant authoritative reference. A displayed review date records the latest internal content and calculation review; it does not mean that an external authority endorsed the Tool. Pages without a methodology panel rely on their visible formula, worked example, assumptions and risk notice pending further documented review.

Corrections and feedback

To report a possible error, use the published contact address and include the page URL, inputs used, observed result, expected result and any supporting source. Reports are reviewed before changes are made so that a correction does not create a new calculation or translation error.

资金

The Website is configured for advertising and may display clearly labelled affiliate placements. Availability varies by page, region, consent and third-party approval. Commercial relationships do not determine Tool formulas or results and are governed by the Advertising Disclosure, Affiliate Disclosure and applicable privacy choices.
