Effective date: June 17, 2026

Stack Tracker ("the app") is a precious-metals collection tracker published by Gold Spartan ("we," "us"). This policy explains how the app handles your information on both iOS (Apple App Store) and Android (Google Play).

The short version: Stack Tracker does not collect, transmit, or sell any of your personal information.

Information we collect

None. Stack Tracker has no user accounts, no login, no analytics, no advertising, and no tracking of any kind. We, the developer, never receive your collection data or any personal information.

Where your data lives

Everything you enter — your items, photos, purchase prices, spot prices, goals, and notes — is stored only on your device, in the app's private local storage. It is not uploaded to us or to any third party.

Optional features that use the internet

The app is offline by default. Two optional, user-initiated features may use a network connection:

Photos and camera

If you add photos to items, they are stored locally on your device only. The app requests camera access solely to let you photograph your own items; photos are never transmitted to us.

Purchases

Stack Tracker offers a one-time in-app purchase ("Unlimited"). Payments are processed entirely by Apple (App Store) or Google (Google Play). We do not collect, see, or store your payment details. Please refer to Apple's or Google's privacy policies for how they handle transactions.

Data sharing and selling

We do not share, sell, rent, or disclose your information to anyone, because we do not collect it in the first place.

Children's privacy

Stack Tracker is not directed at children and collects no data from anyone, including children under 13.
