Privacy Policy

Effective date: [CONFIRM BEFORE PUBLICATION]

This Privacy Policy explains how FormuDesk handles information when you use the FormuDesk iOS application, a tool for editing, calculating, and verifying mathematical formulas.

This policy reflects the developer-provided description of the app's data practices. Before publication, the developer must verify that the released app, its dependencies, and its integrations operate consistently with these statements.

1. Developer and Contact Information

FormuDesk is operated by tao xu, an individual developer based in China.

For privacy questions, contact: xutao9987@gmail.com.

2. Formula Content and Calculation History

According to the app's stated design, formulas you enter or edit, calculation inputs and results, and formula history are processed and stored locally on your device. This information is not intentionally uploaded to a developer-operated server.

The developer does not operate a server-side formula history service according to the information provided for this policy.

If you choose to copy, export, share, or otherwise transfer content to another app or service, the selected content may be handled by that destination under its own terms and privacy practices.

3. Optical Character Recognition (OCR)

FormuDesk's OCR processing is described as taking place locally on your device. Images or recognized formula content are not intentionally sent to the developer for OCR processing.

Before publication, this statement must be checked against the actual implementation, including any OCR framework, optional feature, or network-dependent fallback used by the released app.

4. Information Collection and Third-Party Services

Based on the information provided by the developer, FormuDesk does not use third-party SDKs and does not intentionally transmit your formulas, formula history, or OCR images to the developer.

The app's handling of crash reports, diagnostic information, device information, and other technical data has not been independently verified for this draft. The developer must review the final app build and all dependencies before making a definitive statement about whether any such information is collected or transmitted.

Apple may process information associated with App Store distribution, in-app purchases, and platform services under Apple's own terms and privacy policies. Such processing is governed by Apple's policies, not this policy.

5. In-App Purchases

FormuDesk uses Apple's App Store in-app purchase system. Apple processes purchase payments through its platform. The developer does not receive your full payment card details through FormuDesk.

Apple may process transaction information as needed to complete purchases, manage purchase entitlements, prevent fraud, and provide purchase support, subject to Apple's applicable terms and privacy policies.

The exact purchase products offered by FormuDesk, including whether they are one-time purchases, consumable products, or subscriptions, must be confirmed before publication.

6. Local Storage, Retention, and Deletion

Formula content and history stored locally are subject to the storage and deletion behavior of the app and iOS. The exact in-app deletion controls, app-removal behavior, and backup behavior have not been confirmed for this draft.

If you need to remove stored content, use any applicable deletion controls provided by FormuDesk. You may also manage your device and backup settings through iOS. Removing the app should not be assumed to remove copies that may exist elsewhere, such as in backups or in another app to which you exported content.

FormuDesk does not maintain a developer-operated server-side formula history according to the information currently provided.

7. Data Security

Local processing reduces the need to transmit formula content to a developer-operated server. However, no app or storage method can be guaranteed to be completely secure. You are responsible for maintaining appropriate security on your device.

8. Children's Privacy

FormuDesk is a formula utility. Its intended age rating and whether it is directed to children have not been confirmed in the information supplied for this policy. The developer must verify the intended audience and applicable legal requirements before publication.

9. Changes to This Privacy Policy

This Privacy Policy may be updated when the app's functionality, data practices, or applicable requirements change. The effective date at the top of this page should be updated when a revised policy is published.
