This policy explains what Etherstar Jewels collects for Diamond Calc and why.

What we collect

• When you buy: name, email address and mobile number, to create your access code, email it to you, and provide support. Payments are processed by Razorpay; we do not see or store card, UPI or bank details.
• For licensing: an anonymous device identifier and phone model, to give each phone one free trial and to lock each code to one phone.

What we do not collect

Your lots, prices and calculations stay on your phone. They are not sent to our servers.

How data is used and stored

Data is stored securely with our service providers (Supabase for the licence database, Resend for sending emails, Razorpay for payments) and used only to provide the service. We do not sell your data or use it for advertising.

Your choices

You can ask us to show, correct or delete your purchase details by contacting us. Deleting them ends the subscription linked to them.
