Privacy Policy
Last Updated: February 2026
This privacy policy governs your use of the software application dminder ("Application") for mobile devices that was created by Ontometrics. The Application is a comprehensive Vitamin D tracking app. It uses the GPS in your phone to determine your location, then computes when you can get Vitamin D, how much you can make, provides a timer, and the ability to manage history and estimate your levels on an ongoing basis.
What information does the Application obtain and how is it used?
User Provided Information
The Application uses data you provide when you install it, including some basic health information like birthday, weight, and height. If you are using a health platform, the Application will integrate with it and obtain the data from there. We currently support Apple Health (iOS) and Health Connect (Android). We do NOT disclose the data obtained to any third parties. The current version never moves the data off your device.
Automatically Collected Information
The Application may collect certain information automatically, including, but not limited to, the type of mobile device you use, your mobile device's unique device ID, the IP address of your mobile device, your mobile operating system, the type of mobile Internet browsers you use, and information about the way you use the Application. We do not use that data nor do we share it with any third parties. We do not have access to this information. It is stored on your device only.
Advertising
The Application may display ads via Google AdMob. These services may collect device identifiers for ad personalization. You can opt out of personalized advertising in your device settings. For more information, see Google's Privacy Policy.
Does the Application collect precise real time location information of the device?
The Application uses your device's location to calculate solar position and determine when Vitamin D production is possible at your location. Location data is used only for these calculations and is not transmitted to any external servers.
Do third parties see and/or have access to information obtained by the Application?
No. Your personal health data remains on your device. The only third-party service that may receive non-personal device information is Google AdMob for advertising purposes, as described above.
What are my opt-out rights?
You can stop all collection of information by the Application easily by uninstalling the Application. You may use the standard uninstall processes as may be available as part of your mobile device or via the mobile application marketplace or network.
Data Retention Policy, Managing Your Information
Data is retained within the Application on your device. If you are using a health platform (Apple Health or Health Connect), when you delete the app it will ask if you want to retain the data it wrote to the health store.
Children
The Application is not directed to children under the age of 13. We do not knowingly collect personal information from children under 13.
Security
Your data is stored locally on your device. We do not collect or store any of your personal information on external servers.
Changes
This Privacy Policy may be updated from time to time for any reason. We will notify you of any changes to our Privacy Policy by posting the new Privacy Policy here and in the release notes of whatever version made use of the new policy. You are advised to consult this Privacy Policy regularly for any changes, as continued use is deemed approval of all changes.
Your Consent
By using the Application, you are consenting to our processing of your information as set forth in this Privacy Policy now and as amended by us. "Processing" means using cookies on a computer/handheld device or using or touching information in any way, including, but not limited to, collecting, storing, deleting, using, combining and disclosing information, all of which activities will take place in the United States. If you reside outside the United States, your information will be transferred, processed and stored there under United States privacy standards.
