Privacy Policy

Last updated: 2 July 2026

What Data We Collect

Almost nothing. GradeKar's calculators run entirely in your browser: the CGPA/percentage values you type into a calculator are processed on your device and are never sent to our servers. The one exception is the optional paid conversion certificate — if you choose to buy it, the details you enter for it (your name, university, CGPA and optional roll number) are sent to our server only to generate that one PDF, and are not kept afterward (see Payments below).

No Accounts

We do not require signup or login to use the site, and the free calculators collect no personal information at all. If you buy the conversion certificate, you provide your name (and optionally a roll number) so it can be printed on the document; we use it only to generate your PDF and do not retain it after it is generated. Any email or phone number you enter at Razorpay's payment checkout is held by Razorpay, not by us.

Analytics

We use Google Analytics (GA4) to understand how many people visit our site and which pages are most popular. Google Analytics collects:

  • Pages visited and time spent
  • Device type (mobile/desktop) and browser
  • Approximate geographic location (country/city level)
  • Referral source (how you found us)

This data is aggregated and anonymous. We cannot identify individual users from analytics data.

Cookies

Google Analytics sets cookies to distinguish unique visitors. These are standard analytics cookies. We do not set any cookies ourselves beyond what is required for basic site functionality.

Advertising

We may display ads via Google AdSense to support the free operation of this site. Google may use cookies to serve ads based on your browsing history. You can opt out of personalized ads at Google Ads Settings.

Payments

The calculators are free. If you buy the optional conversion certificate, payment is processed by Razorpay. We do not collect or store your card, UPI, or bank details — those are handled entirely by Razorpay. Razorpay records the transaction (order and payment reference, amount, and any email or phone you enter at its checkout) so the payment can be verified and any refund processed. See Razorpay's Privacy Policy. The certificate you generate is built on the spot and is not stored on our servers.

Third-Party Services

Data Retention

We do not store any user-generated data. Calculator inputs exist only in your browser's memory and are lost when you close the tab.

Children's Privacy

This site is intended for students aged 16 and above. We do not knowingly collect data from children under 16.

Changes

We may update this policy from time to time. Changes will be posted on this page with an updated date.
