Interest Crunch Privacy Policy
Version: 1.0
Effective date: October 22, 2026
Interest Crunch is provided by Alnilam Technologies LLC ("Alnilam," "we," "us"). It is a one-time-purchase calculator for interest and payment estimates. You do not need to create an account, and the app does not contain advertising. This policy covers Interest Crunch, not WorldPulse or other Alnilam Technologies' products.
On-device calculations
Interest Crunch processes the amounts, rates, dates, terms, and payment values you enter on your device. The app does not send your calculator inputs or results to any cloud servers. We do not maintain a server-side calculation history, connect to your bank accounts, or create a customer profile from your calculations.
We do not sell calculator information or share it for targeted advertising. You do not need to provide a name, email address, phone number, bank login, or payment-card details to use the calculator.
Exports and sharing
When you choose to export a calculation or schedule, the app creates a file on your device, such as a PDF or CSV. Preparing an export can create a temporary local file. This is different from sending your information to Alnilam.
If you save or share an export through Files, email, a cloud-storage provider, or another app, that destination receives the information you choose to send and handles it under its own terms and privacy practices. Review exports before sharing them. Copies you save or send may remain outside the app after you close or uninstall it; manage those copies and backups through the relevant device or service controls.
Apple purchases and device services
Apple handles the App Store purchase using your Apple Account. We do not receive your full payment-card details or Apple Account password. Apple may provide us with sales reports and, depending on your device settings, app diagnostics or usage statistics in aggregate or a form that does not personally identify you.
Apple's handling of purchases, device backups, and diagnostics is governed by the Apple Privacy Policy. You can manage optional diagnostic sharing through your device's privacy settings; see App Analytics and Privacy.
Support
If you choose to email Business@alnilamtechnologies.com, we receive your email address and whatever message, name, or attachments you include. We use that information to respond, investigate the issue, and maintain relevant support records. Please do not send bank logins, payment-card numbers, or financial details that are unnecessary for your request.
Our email and support service providers may process this correspondence for us. We may also disclose it when required by law or reasonably necessary to protect legal rights. We do not sell support correspondence or use it for targeted advertising.
We retain correspondence only as reasonably needed to handle the request, keep relevant business records, and meet legal obligations. You can email us to request access, correction, or deletion of support information, subject to applicable law and legitimate retention requirements. We cannot retrieve calculations or exports that you have not sent to us.
Children, changes, and contact
The app does not ask users, including children, to submit personal information. If you believe a child has sent personal information to support, contact us so we can address it and delete it where appropriate.
We will post a new version if our practices change and provide any additional notice or choice required by law before introducing materially different collection. A policy update does not itself enable new data collection in the app.
