Compound Investor privacy
Updated 5 October 2026
This policy describes the current local implementation. Final app release configuration remains to be verified.
Compound Investor is an educational scenario calculator made by Eternal Academy. It does not require an app account, connect to bank or investment accounts, or execute investments. For privacy questions, email contact@eternalacademy.com.
Information stored on your device
The app stores saved plans, your selected currency and whether you completed the walkthrough locally on your device or in your browser’s local storage. Saved plans include their names, optional notes, the financial assumptions you enter, currency and creation/update times.
Calculations run on your device. The current implementation has no developer-operated plan server, app account, cloud sync, advertising or analytics SDKs. Eternal Academy does not automatically receive your saved plans or financial assumptions. This does not describe the separate data handling of services you choose to open, or operating-system diagnostics.
Returning from the background preserves the current plan while the process remains running. After a full process restart, the app starts a fresh unsaved plan and loads saved plans and preferences from local storage. Unsaved work is not stored for restart recovery.
Optional sharing
Choosing Share generates a projection image on your device. It can contain the plan name, amounts, currency, growth and inflation assumptions, duration, chart and results. Optional plan notes are excluded from that image. The sharing request also includes a title, short app description and the plan name as its subject when present.
You choose the destination using the device’s sharing controls. Review the content before sharing; the selected app, recipient or service handles it under its own privacy practices. A manually captured screenshot may contain notes. Sharing an image does not create an editable backup or sync your plan.
Feedback, support and external links
The default feedback link opens your email app to contact@eternalacademy.com. It does not automatically attach saved plans, assumptions or device diagnostics. You choose what to send and can cancel before sending. If you email Eternal Academy, we receive your email address and message so we can respond. Your and our email providers handle the message too.
A release can configure an external feedback form instead. Visiting a configured form or other external website subjects the information you submit and connection to that service’s privacy practices. Avoid sending bank details, account information, credentials or private plan names, notes or amounts; use synthetic data for screenshots.
For questions or requests about information you have sent to Eternal Academy, contact us about privacy.
Optional support payments
Where available on iOS, optional one-time tips are processed by Apple through the App Store. The app queries tip products and receives product and transaction status information to acknowledge and complete a tip. It does not receive your payment card details. Apple handles its services under Apple’s privacy policy.
On web and Android, you may choose to open Buy Me a Coffee. That external service and its payment providers process the information you provide under its privacy policy. Supporter details you choose to provide may also be made available to the creator through that service. No tip or payment unlocks planning features.
Deletion, backups and device services
You can delete a saved plan within Saved. Clearing local app or browser data can remove saved plans and preferences. The app has no in-app restore or editable-plan backup/import feature. Local data may be included in operating-system backups depending on platform settings; recovery is not guaranteed by this app.
Deleting a plan or local app data does not remove earlier operating-system backups, shared images, recipients’ copies, support emails or payment-service records. Manage those copies and records with their respective services. Apple or other platform services may process diagnostics according to your device settings and their own policies.
