Your Data StaysOn Your Device

ScaleScan is designed to work on your device. By default, the data you create and the processing the app performs stay on your device and within the app. ScaleScan only sends data off the device or out of the app if you choose settings that do that — for example, if you enable syncing, backup, sharing, or optional diagnostics.

This means you remain in control. Unless you turn on a feature that transmits data, your information is not uploaded to us or to any third party.

Separately from the app, your device's operating system may manage the app's data — for example, Apple's iCloud backup, or Apple Health if you have permitted ScaleScan to write your weight to it or read it from there. Any such data is managed by Apple according to the permissions and choices you make in your Apple device settings and is subject to Apple's device and data privacy policies rather than this policy. You can review, change, or revoke these options at any time in your device settings.

ScaleScan does not require you to create an account, and it does not use one. There is no registration, no username or password, and no user profile associated with the app.

Because there is no account, we do not collect account credentials, and there is no server-side identity linked to your use of the app.

ScaleScan is built around data minimization. The categories of data the app handles are summarized above. In normal use, this information is stored and processed locally on your device.

ScaleScan helps you record and track your weight, which is health-related information. We treat this as sensitive data: by default it stays on your device and is not transmitted to us or any third party unless you choose a setting that sends it. ScaleScan does not require any other sensitive personal information — such as financial or biometric identifiers — to use its core functionality, and does not collect such information unless a specific feature clearly requests it and you consent.

Information handled by ScaleScan is used to provide the features you request, to keep the app running reliably, and to perform the scans and tasks you initiate. When processing happens on your device, that information is not visible to us.

If you choose to enable a feature that sends data off the device, that data is used only to deliver the feature you turned on — such as syncing your content across devices, backing it up, sharing it, or helping us diagnose crashes. We do not use your personal data for automated decision-making that produces legal or similarly significant effects, and we do not sell your personal data.

Data stored on your device is protected by your device's own security controls, including its operating system protections and any passcode or biometric lock you use. Where that data is held by Apple — for example in an iCloud backup or in Apple Health — it is protected by Apple's security measures in accordance with your Apple device settings and Apple's data policies.

When you enable a feature that transmits data, that data is encrypted in transit using TLS and, where stored by a service provider, encrypted at rest using strong, modern encryption standards. While no method of transmission or storage is ever completely secure, we apply industry-accepted safeguards to protect any data that does leave your device.

Because ScaleScan works on-device by default, we do not share your content with third parties in normal use. Sharing only occurs when you enable an optional feature that involves a service provider — such as cloud backup, sync, or crash reporting.

Where such providers are used, they are bound by contractual obligations to protect your data and to use it only for the services they perform on our behalf. We may disclose information only if required to do so by law, to comply with a valid legal process, or to protect the rights, property, or safety of our users or the public.

Apple is not a third party acting on our behalf. Where Apple handles data — for example through iCloud backup, Apple Health, or the App Store — it does so as the provider of your device and platform, according to your Apple device settings and Apple's own privacy policy.

Data stored locally on your device remains until you delete it within the app or remove the app. You are in control of local data at all times. If your device has backed that data up to iCloud, or you have written weight entries to Apple Health, its retention and deletion are managed by Apple through your Apple device, iCloud, and Apple Health settings in accordance with Apple's data policies. Removing ScaleScan does not automatically delete entries already saved in Apple Health.

For any data you have chosen to send off the device, we retain it only as long as necessary to provide the feature you enabled and to meet our legal obligations, after which it is securely deleted or anonymized.

Depending on your location, you may have rights under regulations such as the EU/UK General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA/CPRA), and the New Zealand Privacy Act 2020. These may include the right to access, correct, delete, or export your data.

For data held on your device, you can exercise these rights directly by managing or deleting it within the app. For any data you have chosen to sync or share off the device, contact us using the details below and we will respond within the timeframe required by applicable law. For data held by Apple, such as an iCloud backup or entries in Apple Health, you can view, manage, or delete it through the Apple Health app, your Apple device settings, or Apple's own privacy tools. We will never discriminate against you for exercising your privacy rights.

ScaleScan is not directed to children under the age of 13 (or the minimum age required in your jurisdiction), and we do not knowingly collect personal data from children.

We may update this privacy policy from time to time to reflect changes in our practices, technology, or legal requirements. When we make material changes, we will update the date at the top of this page and, where appropriate, provide a more prominent notice within the app.

We encourage you to review this policy periodically to stay informed about how ScaleScan protects your information.
