This policy describes how Force vs. Matter handles information, and how information may be handled when you visit this privacy-policy website or contact support.
Force vs. Matter’s experiments and Learn content work on your device without an internet connection or a Force vs. Matter account.
The app does not send your experiment results or Settings choices to the developer. It does not include advertising, tracking, developer analytics or developer-operated accounts. It does not request access to your contacts, location, camera or microphone.
The app stores the following information locally on your device:
Tool and material selections, experiment results, and Learn search and reading state are temporary session information. The app does not provide persistent experiment history or iCloud/CloudKit synchronization.
Historical completion data from an earlier app version may remain in local storage. It is not transmitted to the developer.
Local preferences remain until changed, removed with the app’s local data, or restored from a device backup. Restore Defaults resets the preferences shown in Settings while preserving your Welcome status. Show Welcome displays the introduction again.
Because this information stays on your device, the developer cannot access or remotely delete it.
Apple handles App Store purchases and downloads separately. The app does not receive or store your payment-card information.
Apple may handle device backups, restored app data and system diagnostics according to your device settings and Apple’s policies. Removing or reinstalling the app may not clear information subsequently restored from a device backup.
For information about Apple’s practices, see Apple’s Privacy Policy.
This website is hosted using GitHub Pages. GitHub states that visitors’ IP addresses are logged and stored for security purposes, whether or not visitors are signed in to GitHub.
GitHub’s handling and retention of website information are governed by its Privacy Statement. Requests concerning information held by GitHub should be directed to GitHub.
Website hosting is separate from the app’s local experiment and preference storage.
If you contact us, we receive the information you choose to provide, which may include your email address, message and attachments. We use this information to respond to your request and address the issue you report.
You do not need to provide experiment results, screenshots or diagnostic files unless you choose to do so. Please avoid sending passwords, payment information or other sensitive information.
Our email service provider processes correspondence to deliver and store messages. Your own email provider may also process messages. Each provider’s handling of this information is subject to its own privacy policies.
We retain support correspondence only as long as reasonably necessary to respond to your request, resolve related issues or meet legal obligations. When it is no longer needed, we delete it from the systems we control. Copies in an email provider’s backups may remain until removed according to that provider’s retention practices.
The app does not transmit locally stored preferences or experiment information to the developer.
We do not sell support correspondence or use it for advertising. We share it only with service providers needed to receive, store and respond to messages, or when disclosure is required by law.
Apple and GitHub handle information through their respective services as described above.
You may contact us using the privacy contact listed at the beginning of this policy to ask about support information we hold or request access, correction or deletion.
We may need to verify that a request concerns your information. We may retain information when required by law or necessary to resolve an ongoing matter, and will explain any applicable limitation when responding.
Deleting support correspondence does not delete information held independently by Apple, GitHub or your email provider. Requests concerning those services should be directed to the relevant provider.
We will update this policy if the app’s or website’s information-handling practices change. The effective date above identifies the latest revision.
