Privacy Policy

Last updated: July 9, 2026

    The short version: Prism: Calculator does not collect, store, or share any of your
    personal data. Everything you calculate stays on your device.
  

1. Who we are

Prism: Calculator ("the App") is developed and published by APP_PUBLISHER ("we", "us"). This policy explains how the App handles information when you use it on your iPhone, iPad, or Android device.

2. Data we collect

We collect no personal data. Specifically:

All calculations, history entries, notes, and settings are stored locally on your device only. They are never transmitted to us or to anyone else.
The App contains no advertising and no third party advertising SDKs.
The App contains no analytics or tracking SDKs. We do not use identifiers, cookies, or fingerprinting of any kind.
We do not require an account, email address, or any registration.

3. Currency exchange rates

The currency converter periodically downloads up-to-date exchange rates from a public content delivery network. This is a simple, anonymous request that works like loading a web page. It contains no personal information, no device identifiers, and nothing about your calculations. If you are offline, the App uses the most recently saved rates instead, and no request is made.

4. Purchases

The optional Pro upgrade is a one-time purchase processed entirely by Apple (App Store) or Google (Google Play). We never see or store your name, payment details, or billing information. Payment processing is governed by the privacy policy of Apple or Google respectively.

5. Children's privacy

The App is suitable for all ages. Because we collect no data from anyone, we also collect no data from children.

6. Data retention and deletion

Since we do not collect your data, there is nothing for us to retain or delete on our side. You can erase all locally stored data at any time by clearing the calculation history inside the App or by deleting the App from your device.

7. Changes to this policy

If we ever change how the App handles data, we will update this policy and the "Last updated" date above before the change takes effect. A change that would introduce any data collection would also be reflected in the App Store privacy label.
