10. 联系与隐私请求
1. Overview
This version does not require an account. Sumvia supports health calculations and personal records, and its core calculations do not depend on a remote account service.
We do not use the app to actively collect your name, contact details, or health data you enter, and we do not use in-app data to build advertising profiles.
2. Data categories and purposes
The following information is stored on this device by default:
- favorite and recently used calculators;
- calculation history you choose to retain;
- language, reading, and unit preferences; and
- local settings needed for the app to display and operate correctly.
This information is used only on your device to perform calculations, show favorites and history, and remember display preferences. It is not transmitted to a server operated by us. The current app does not integrate advertising, analytics, or crash-reporting SDKs and does not request HealthKit, location, contacts, camera, or microphone access.
3. User-initiated sharing
When you choose to share a result summary or formula image, Sumvia opens the system share sheet. Content is handed to another app or service only after you select that destination.
The destination app or service handles the content under its own privacy policy. Before sharing, check that the content does not include information you do not want to disclose.
4. Website data practices
This is a static website. It requires no registration or login and does not use analytics, advertising, or tracking scripts. It also does not set marketing cookies.
When you select an email support link, your browser opens the email app on your device. Your chosen email provider handles the message and subsequent processing. Do not send sensitive health information through ordinary email.
A static hosting provider may still process an IP address and basic access logs to deliver pages. The final hosting provider, log-retention period, and processing region are not specified in this repository and must be verified when the production domain is configured.
5. Retention and deletion
On-device records remain until you use an in-app clearing option, clear the app’s system data, or uninstall the app. Sumvia has no remote account database in the current version, so there is no app account or cloud health record for us to delete on your behalf.
If you email support, the message is handled by your email provider and ours. The publisher must confirm a support-email retention period. You may use the privacy request contact below to ask about or request deletion of support correspondence we control.
6. Health-reference boundary
The app provides health calculation references and personal record support only. It cannot replace assessment or advice from a qualified professional and is not intended for diagnosis, treatment, prescriptions, or emergency decisions.
7. Your choices and rights
You can choose not to retain calculation history, delete local records, stop using sharing features, or uninstall the app. Visit the support page if you need help removing local data.
To make an access, correction, deletion, or other privacy request, use “Privacy request” in the email subject and provide only the minimum information needed. Available rights depend on the law applicable where you live.
8. Children and regional applicability
Sumvia is not designed specifically for children. The current app does not require an account or collect children’s personal information through the app to a server we operate. Calculators involving age or pediatric reference values should be used by a parent, guardian, or qualified professional in context.
Requirements for children, health information, and consumer rights vary by region. The publisher must confirm distribution regions, minimum applicable age, and any required local notices before release. This policy does not replace those notices.
9. Policy updates
If the app’s data practices change materially, we will update this policy before releasing the related feature and revise the effective date shown on this page.
10. Contact and privacy requests
Questions about this policy, Sumvia’s data practices, or a privacy request can be sent to . The publisher must verify that this mailbox and domain are operational before launch.
