1. Contact Directory
ApexConverter runs two monitored inboxes. Use the public inbox for anything about the calculators themselves, and the administrative address for anything that creates a formal record — privacy rights, security disclosure, legal notices, and commercial licensing.
apexconverter.praxiscalc@gmail.com
Administrative & Legal
Privacy and data rights, security disclosure, licensing, partnerships and legal notices.
Acknowledged within 48 hours.

2. Reporting a Calculation Error
We treat mathematical errors as the most serious class of defect on the platform. To get yours resolved fastest, include all five of the following:
- The exact tool URL — copied from the address bar, not the tool name.
- Every input value you entered, including any you left at their defaults.
- The output you received, copied precisely.
- The output you expected, with your working or a citable source.
- Your browser and device, which matters for display and rounding issues.
Verified mathematical errors are patched within 72 hours and the tool's methodology section is updated to record the correction.
3. Requesting a New Calculator
Our build queue is driven by user demand. A strong request includes the proposed tool name, the formula or published standard it should implement, the input fields a practitioner would expect, and a short note on the audience and use case. Requests accompanied by a citable formula source move to the front of the queue because they eliminate the longest stage of our review process.
4. Licensing and Commercial Use
Editorial iframe embedding with visible attribution requires no permission — see our Terms of Service. Beyond that, we license engines commercially:
- White-label deployment — our engines under your branding, attribution removed.
- Bulk category licensing — an entire vertical for an industry platform.
- Custom engine development — proprietary calculations built to our standards, delivered as self-contained client-side components.
Licensed engines retain the client-side architecture, so your users' data stays on their devices too.
5. What We Do Not Respond To
In the interest of everyone's time, the following receive no reply:
- Guest post offers, sponsored content pitches, and link-exchange proposals — we publish no external contributions at any price.
- SEO, backlink, and traffic-growth solicitations.
- Requests to remove or alter a correct calculation because it produces an unfavourable result.
- Automated vulnerability scanner output submitted without manual validation.
6. Expert Commentary for Media
Our domain leads are available for comment on mortgage mathematics and rate sensitivity, personal and corporate taxation mechanics, SaaS and business unit economics, and quantitative health and fitness metrics. Contact apexconverter.praxiscalc@gmail.com with your outlet, deadline, and the specific angle. We provide factual, computational commentary and do not offer market forecasts or investment opinions.
Frequently Asked Questions
5 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
How quickly will I get a reply?
Calculation error reports are triaged within 24 hours and verified fixes are typically deployed within 72 hours. Security reports are acknowledged within 48 hours. General enquiries and partnership requests receive a response within three to five business days.
How do I report a wrong calculation result?
Email apexconverter.praxiscalc@gmail.com with the exact tool URL, every input value you used, the output you received, and the output you expected together with your source or working. Complete reports are resolved dramatically faster than reports stating only that a number looks wrong.
Can I request a calculator that does not exist yet?
Yes, and we genuinely use these requests. Send the proposed tool name, the formula or standard it should implement, and a brief note on who needs it and why. Requests supported by a citable formula source are prioritised in the build queue.
Do you offer white-label or API access?
Commercial licensing for white-label deployment and embedding without attribution is available. We do not currently offer a hosted calculation API, precisely because our architecture is deliberately server-free — licensed engines are delivered as self-contained client-side components.
Do you accept guest posts or link exchanges?
No. We do not publish guest contributions, sell links, or participate in reciprocal link schemes. All content on ApexConverter is written and reviewed in-house by credentialed specialists, and this policy is not negotiable at any price.
