JewelXGold Calculator · Updated 29 September 2026

This notice applies to calculator.jewelxgold.in. For questions or requests concerning your calculator account, contact 9kappstudio@gmail.com.

Account information

When you choose Google sign-in, Google shares your email address, account identifier and basic profile information, such as your name and profile picture, with our authentication service, Supabase. We use this information to identify your account and associate its credit balance with you. The calculator does not request access to your Gmail messages, contacts or Google Drive.

Calculator and credit records

Calculation inputs are sent to our server to compute results. During the free preview, calculations do not deduct credits or create paid calculation records. When paid calculations are enabled, calculation inputs, results and credit deductions are recorded against your account. Credit purchase and adjustment records are used to maintain your balance and resolve payment issues. Payments are currently disabled.

Service providers and storage

Cloudflare hosts the calculator and its server endpoints. Supabase provides authentication and the database; the project's database region is Seoul, South Korea. These services process account, request and technical information needed to run and secure the service. Hosting and authentication logs may include IP addresses and request information.

The browser uses session storage for your login session and a pending calculation request. Logging out removes the local session; it does not erase your server-side account or credit records. Browser sessions expire, so you may need to sign in again. Google uses its own login cookies under its policies.

Use and access

The calculator uses Google account data for sign-in and account identification. Its integration does not use this data for advertising or request permissions to read your other Google content. Account access is checked on the server, and database access rules separate users' credit records.

Your choices

You can use the free preview without Google sign-in, log out, or revoke the calculator's Google access from your Google Account connections. To request access, correction or deletion of your calculator account data, email the support address above from your registered email. Identity may need to be verified before a request is processed. Revoking Google access alone does not delete calculator records. Records may need to be retained for unresolved transactions, security or applicable obligations.

This notice will be updated when the calculator's data practices change. Check this page before using newly enabled payment features.
