Gold Purity Weight Converter · Last updated 24 August 2026
The calculator collects nothing. Converting karat weights works with no account and requires no personal information. Everything below applies only if you choose to create an optional account.
An account is optional. It exists so you can save jewellery records and reach them from more than one device. If you create one, we collect:
We do not collect your location, contacts, photos, device identifiers, advertising identifiers, or usage analytics.
Account and jewellery data are held with Supabase, our database provider, and transmitted over an encrypted connection. Each account can read only its own records.
Your data is used solely to operate the app: to sign you in and to show you the records you saved. We do not sell it, rent it, or share it with third parties. We do not use it for advertising and we do not track you across other apps or websites.
You can permanently delete your account and all associated data from inside the app, under the Account tab. Deletion is immediate and cannot be undone. You may also email shardatw@gmail.com to request deletion.
The app is a professional tool for the jewellery trade. It is not directed at children under 13, and we do not knowingly collect data from them.
If this policy changes, the updated version will be posted at this address with a new date at the top.
