Privacy Policy for Sensor Logger

We are committed to protecting your personal information and your right to privacy. When you use our mobile application, we appreciate that you are trusting us with your personal information. We take your privacy very seriously. If there are any terms in this privacy notice that you do not agree with, please discontinue the use of our App immediately.

If you use our App, the App collects the following information. This information is needed to maintain the operation and primary functionality of our App, which is to record and log information about the location and state of the phone and its surroundings. By default, all information is stored locally on the device, and we do not have access to any recorded data or user information.

1. Geo-Location Information. We request permission to location-based information from your mobile device, either continuously or while you are using our App, to provide certain location-based logging.
2. Mobile Device Access. We may request access or permission to certain features from your mobile device, including your mobile device's storage, sensors, and other features. If you enable audio recording, then this also includes microphone access.
3. Mobile Device Data. We store device information (such as your mobile device ID, model and manufacturer), operating system, version information and system configuration information, device and application identification numbers.
4. Health Data. The App accesses heart rate data from HealthKit if and only if you explicitly toggle the heart rate sensor logger functionality explicitly with a paired Apple watch on the iOS version of the App. No other health information is accessed. The heart rate measurement stays on the device (on the iOS App, not the watch App).
5. Camera Data. If you explicitly toggle the Camera sensor on, the App may access and store images captured from your mobile device's camera.

If the user toggles a certain set of sensor(s) off on the logger screen, those sensors will remain inactive through the recording and nothing will be read/stored from those sensors.

We do not knowingly solicit data from or market to children under 18 years of age. By using the App, you represent that you are at least 18 or that you are the parent or guardian of such a minor and consent to such minor dependent's use of the App.

Telemetry

We may also collect anonymous telemetry data to help us understand how the App is being used and to improve its functionality. This may include information about how often the App is used, the features that are used most frequently, and any errors that occur during use. This information is collected in a way that does not personally identify any individual user and is only used for the purposes of improving the App for all users. By using the App, you consent to the collection of this anonymous telemetry data.

Cloud Service

We offer an optional, opt-in cloud service where users can ask other Sensor Logger users to contribute their private recordings. The data is encrypted in transit and in storage. If you choose to participate, recordings you make explicitly for the Study are accessible by the Study investigator. The Study investigator will provide an email point of contact and any additional data usage policy specific to that Study. Please note that this is a voluntary feature. By enabling this feature, you assume all responsibility for any risks associated with sharing your recordings with other users.

The cloud service uses infrastructure provided by Cloudflare, their policies are located at www.cloudflare.com/en-gb/trust-hub/

User Data Deletion

To request the deletion of your data from Sensor Logger Cloud, please send an email to sensorlogger@tszheichoi.com. In the email, include relevant information that will help us identify your account. Once we verify your request, we will permanently delete your identifiable data from our system and notify you via email. Please note that this process may take some time. For any other inquiries about data deletion, contact us.

Changes to This Privacy Policy

We reserve the right to modify this privacy notice at any time, so please review it frequently. Changes and clarifications will take effect immediately upon their posting on the App. If we make material changes to this policy, we will notify you here that it has been updated, so that you are aware of what information we collect, how we use it, and under what circumstances, if any, we use and/or disclose it.
