Privacy Policy

Last updated: March 19, 2026

Neon Grain ("we", "us", or "our") operates the ScribbleCalc mobile application. This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our Service.

Information Collection and Use

We value your privacy. ScribbleCalc is designed to be a private tool. Outside of the third-party services mentioned below, we do not collect, store, or transmit any personal identification information from our users.

Third-Party Services

To provide our features and support development, we use the following third-party services:

• Google AdMob: For users of the free version, we use Google AdMob to serve advertisements. AdMob may collect and use information about your device, such as your IP address, device identifiers (e.g., IDFA or AAID), and ad interaction data. This information is used by Google to provide, measure, and personalize advertising.
• RevenueCat: We use RevenueCat to manage in-app purchases and subscriptions. RevenueCat may collect transaction-related data and anonymous device identifiers to process and validate your purchases.
• Google Play / Apple Store In-App Review: We use official platform APIs to request reviews. No personal data is collected by us during this process.

Data Storage

ScribbleCalc stores your calculation history and application settings locally on your device using the Hive database. This data stays on your device and is not synchronized to our servers.

Data Security

Since we do not collect or transmit your personal identification information directly, the risk of data breaches on our servers is minimal. However, we encourage you to secure your own device to protect the data stored locally.

Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
