Privacy Policy

Last updated: July 26, 2026

This Privacy Policy applies to the GoldMate (Gold Price Converter) iOS app. It explains what information we collect when you use the app, how we use it, and — just as importantly — what we don't do. Our principle is simple: we only collect what the app's core features actually need, we never share your information with third parties for advertising purposes, and we don't track your activity across other apps or websites.

Information We Collect

Device Identifier
The first time you use the app, we generate a random identifier on your device to help us understand feature usage patterns and improve the product. This identifier is generated locally on your device (not derived from any hardware fingerprint) and contains no information that could directly identify you personally, such as your name or email address.
Subscription Status
Subscriptions are handled entirely through Apple's In-App Purchase (StoreKit) system — we never see or store your payment details (card numbers, Apple ID password, etc.); those are processed exclusively by Apple. To confirm your subscription is active and to guard against tampering, the app also sends Apple's signed transaction receipt to our server, which records a small set of non-personal fields tied to Apple's own transaction identifier: which product was purchased (monthly or yearly), the purchase and expiration dates, and whether the subscription is still active. This identifier is opaque and does not reveal your Apple ID, name, or any other personal information.
Usage Data
We record basic interaction data — such as opening the app, tapping specific features, or how long a screen is viewed — to help us understand how the product is actually used and where it could be improved.

Information We Do Not Collect

Location data · Contacts · Photos or videos · Audio recordings · Health and fitness data · Browsing history · Search history · Card numbers or other payment account details · Race, sexual orientation, religious beliefs, or other sensitive personal information

None of the above is ever used for third-party advertising, our own advertising or marketing outreach, or personalized content recommendations.

Information Sharing

We do not sell, rent, or share your information in any form with third-party advertising networks or data brokers, and we do not correlate this data with information from other companies' apps or websites for cross-app tracking or ad targeting purposes. The information described above is used solely to understand and improve our own product.

Data Storage and Security

Your information is transmitted to our servers over an encrypted connection (HTTPS/TLS) and stored there. We take reasonable technical measures to protect your information against unauthorized access, disclosure, or alteration.

Data Retention

We retain your information only for as long as necessary to fulfill the purposes described above. If you'd like to know what information we hold about you, or to request a correction or deletion, please contact us using the details below.

Your Rights

If you are located in the European Economic Area, the United Kingdom, or another region with similar data protection laws, you may have the right to request access to, correction of, or deletion of your personal information, to object to or restrict certain processing, and to lodge a complaint with your local data protection authority. Because the information we hold is limited to the non-personal identifiers described above, most requests can be resolved simply by asking us to clear the identifier associated with your device — contact us using the details below and we'll take care of it.

Children's Privacy

This app is not directed at children, and we do not knowingly collect personal information from children under the age of 13 (or the relevant minimum age in your region). If you believe we may have inadvertently collected information from a child, please contact us and we will address it promptly.

Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we'll let you know through an in-app notice or by updating this page. We recommend checking back periodically to stay informed.
