Purpose
Apex Percent exists to provide browser-based percentage and time-zone tools with clear formulas, examples, and limitations. Its content is made for people with a practical calculation or planning question, not to manipulate search rankings or advertise unrelated products.
Authorship and limits
Alnto Tsekou is the publisher responsible for this site. The site does not claim to be a financial, tax, legal, education, accounting, or time-zone advisory service. We use general examples and direct visitors to official sources when a calculation intersects with rules that vary by location or institution.
Sources and accuracy
We publish source links for technology and external concepts that deserve verification, particularly IANA time zones and internationalisation behaviour. Arithmetic examples are checked against the formulas shown. We avoid precise claims, rankings, or comparisons that cannot be supported.
Editorial assistance
Editorial assistance tools may help organise research, review clarity, or prepare drafts. They do not replace formula checking or source review, and the site does not use them to create mass-produced pages with no distinct user purpose.
Corrections and updates
Use the contact form to report an error or unclear explanation. We review reasonable reports and correct factual, formula, or link errors. Dates are changed only when the content has been substantially updated.
Advertising and commercial disclosure
The site may use advertising to help cover operating costs once it is eligible to do so. Ads will not be used to disguise editorial guidance or to direct visitors into unrelated offers. During this site-review phase, there are no visible ad units, placeholders, or placeholder slot IDs.
