Privacy Policy
Last updated: January 2026
This Privacy Policy explains how we collect, use, and protect your information when you use our mobile application (the “App”).
1. Information We Collect
We collect only the information necessary to provide core app functionality.
- Email address — used for account authentication and account-related communication.
- Subscription information — used to determine your subscription status and access to premium features.
- User preferences — such as app settings and configuration choices.
- Variables and calculations — data you enter while using the calculator features.
2. How Information Is Stored
Most app data, including preferences, variables, and calculations, is stored locally on your device and is not transmitted to our servers.
Email addresses and subscription-related information may be securely stored on our servers or processed through trusted third-party services solely for authentication and subscription management purposes.

4. Data Sharing and Third Parties
We do not sell or rent your personal information.
We may use third-party services for subscription processing and app infrastructure (such as app store providers). These services only receive the minimum data required to perform their function and are obligated to protect your information.
5. Data Security
We take reasonable measures to protect your information. Data stored on your device remains under your control. Any server-side data is protected using industry-standard security practices.
6. Children’s Privacy
The App is not intended for children under the age of 13. We do not knowingly collect personal information from children.
7. Your Choices
You may delete your account or uninstall the App at any time. Data stored locally on your device can be removed by clearing the app’s data or uninstalling the App.
