Plusm ("the App") is a calculator application for macOS and iOS. Your privacy is important to us. This policy explains what data we collect and how we handle it.
Plusm does not collect, store, or transmit any personal data. All calculations are processed locally on your device and never leave it. We collect only anonymous, aggregated usage statistics as described in the Analytics section below.
We use TelemetryDeck to collect anonymous usage data, such as app launches, feature usage, and subscription events. This data is not linked to your identity and cannot be used to identify you personally. No personal information, IP addresses, or device identifiers are collected or shared. TelemetryDeck is a privacy-first analytics provider based in the EU. You can learn more at telemetrydeck.com/privacy.
We do not use any advertising frameworks or cross-app tracking.
Plusm offers optional in-app subscriptions through the Apple App Store. All subscription management and payment processing is handled entirely by Apple. We do not have access to your payment information.
The App may connect to the internet to fetch currency exchange rates. These requests do not include any personal information or device identifiers.
