Questions
Everything students commonly ask about Delvox.xyz — how the calculators work, how accurate they are, what happens to the data you enter, and how the platform is funded. If something is not covered here, reach out and we will answer it directly.
🔢 Using the Calculators
Yes — completely free. Every calculator on Delvox.xyz is free to use with no sign-up, no subscription, and no hidden charges of any kind. The platform is funded through Google AdSense advertising, which is what allows us to keep every tool free for every student.
No account is needed at all. You can use every calculator on Delvox.xyz without registering, signing in, or providing any personal information. Open the tool, enter your values, and get your result immediately.
It depends on the tool. Most calculators only need the marks or grades you already have — for example, your assignment scores, exam results, or subject grades. Each field is clearly labelled so you know exactly what to enter. For GPA and CGPA calculators, you may also need your credit hour values, which your institution provides on your course timetable or transcript.
Yes. Every calculator on Delvox.xyz is fully responsive and works on mobile phones, tablets, and desktops. No app download is required — the site works directly in your mobile browser.
Our calculators cover the most widely used academic systems globally, including:
- The 4.0 GPA scale used in North American institutions
- Percentage-based grading systems common across South Asian universities
- CGPA systems with credit hour weightings
- Weighted grade calculations for subject-level results
- Final exam score requirements based on target grades
We are continuously expanding our coverage. If your institution uses a system we have not covered yet, let us know through our contact page.
You need an internet connection to load the page initially, but once the calculator has loaded in your browser, the actual calculations run locally on your device. A slow or unstable connection will not affect the speed of your results once the page is open.
✅ Accuracy and Results
We build every calculator around established academic formulas and test them carefully before publishing. For the vast majority of students, results will match or come very close to what their institution calculates officially.
This can happen for a few reasons. Your university may apply grade moderation, use a non-standard GPA scale, round grades differently, or exclude certain subjects from the overall average. These are institution-specific rules that vary widely and are not always publicly documented. Our calculators use the most common standard formulas — if your institution deviates from those, a small difference in the final result is expected.
If you believe the difference is due to an error in our formula rather than an institution-specific variation, please report it through our contact page so we can investigate.
No. Our calculators are for personal reference and academic planning only. They are not official documents and should not be presented to universities, employers, or any institution as verified academic records. For formal submissions, always use certified documents issued directly by your institution — official transcripts, grade reports, or letters from your academic office.
Please tell us about it through our contact page. Describe the calculator you were using, what values you entered, what result you got, and what you expected. We take accuracy seriously and investigate all reported errors promptly. If the formula is genuinely wrong, we fix it quickly.
🔒 Privacy and Data
No. All calculations run entirely within your browser. The values you enter never reach our servers — they are processed locally on your device and disappear the moment you close or refresh the page. We have no record of any marks, grades, or academic data you enter into our calculators.
We collect standard, anonymised site analytics through cookies and Google Search Console — things like which pages are visited, what device and browser you are using, and how you found the site. This data is aggregated and never linked to any individual. We do not collect names, email addresses, or any personally identifiable information.
Full details are in our Privacy Policy.
Yes. Delvox.xyz uses cookies for two purposes — standard site analytics to understand how the site is used, and to support Google AdSense in serving relevant advertisements. Advertising cookies are managed by Google, not by us directly.
You can manage or disable cookies at any time through your browser settings. You can also opt out of personalised advertising through Google's Ads Settings.
Yes. The platform contains no inappropriate content — it is an academic tool site. We do not collect personal data from any user, including minors. We recommend students under 18 review our Privacy Policy with a parent or guardian, as is standard practice for any website that uses advertising cookies.
📢 Ads and How the Platform Is Funded
Delvox.xyz is a free platform and advertising through Google AdSense is what keeps it that way. Building and maintaining accurate academic calculators takes real time and resources. Rather than charging students, we display ads — which generates the revenue needed to keep every tool free and the platform running.
No. Advertisements on Delvox.xyz are served automatically by Google based on your browsing activity and page content. No advertiser has any influence over how our calculators work, which formulas we use, or what results they produce. Our tools and educational content are entirely independent from the advertising on the site.
You can opt out of personalised advertising by visiting Google's Ads Settings. You can also opt out of third-party vendor advertising cookies by visiting www.aboutads.info. Alternatively, managing your cookie preferences through your browser settings will also limit ad personalisation.
