How Five Lakes Studio LLC handles information across our website and apps.
Effective October 6, 2026
This Privacy Policy explains how Five Lakes Studio LLC, a Michigan limited liability company ("Five Lakes Studio," "we," or "us"), handles information when you visit www.fivelakesstudio.com (the "Website") or use one of our apps (each an "App"). It replaces our earlier policy dated June 26, 2013.
Some Apps have their own section below. Where an App has its own section, that section describes exactly what the App does with your information and controls over the general sections if they differ. Each App's privacy details on the App Store also describe what it collects.
App sections: Glucose View Insights
We collect as little information as we can, use it only to provide and support our products, and do not sell personal information.
a. Browsing. You don't need to give us personal information to browse the Website.
b. Analytics. We use website analytics from third parties such as Cloudflare to understand how the Website is used in aggregate, for example which pages are visited, how visitors arrived, and general browser, device, and country information. We use this only to run and improve the Website, not to identify you or to advertise to you.
c. Delivery and security. The services that deliver the Website, including Cloudflare and Google Fonts, process standard technical information such as your IP address and browser type to load and protect the site. Cloudflare may set cookies that are strictly necessary for security, such as bot detection.
d. Cookies. We don't use advertising cookies or cookies that track you across other websites.
The third parties named in this section handle information under their own privacy policies.
If you email us for support or with feedback, we receive your email address and whatever you choose to include. We use it to respond to you and to improve our products. We don't add you to a mailing list or share your message for marketing.
a. Permissions. Some Apps ask for permission to use device features, such as your location or Apple Health, to provide their features. You choose whether to allow each one and can change your choice at any time in your device's Settings.
b. Information from Apple. When you download or buy an App from the App Store, Apple handles the transaction. Apple does not give us your Apple ID, name, or payment information. Apple may provide us with aggregated statistics about App Store activity, and with crash reports and diagnostics if you've chosen to share them with app developers in your device settings. These don't identify you to us.
c. Services an App relies on. If an App sends information to an outside service to work, the App's section or its App Store privacy details will say so.
Glucose View Insights shows blood glucose readings from Apple Health. It appears as Glucose View on your Home Screen, and this section uses that shorter name. It is built so that your health data stays on your iPhone.
a. What it reads. With your permission, Glucose View reads Blood Glucose samples from Apple Health: each reading's value, the time it was recorded, and the name of the app or device that saved it. It asks for no other Health data and never writes to or changes anything in Apple Health.
b. How it's used. Readings are used only to show your history, charts, and statistics inside the app on your iPhone.
c. Where it's stored. Glucose View keeps a copy of your readings in its own storage on your iPhone so screens load quickly. That copy is excluded from iCloud and computer backups and can always be rebuilt from Apple Health. Your settings, such as target ranges and appearance, are also stored on your iPhone and may be included in your device backups. Settings don't contain glucose readings.
d. What we receive. Nothing. Glucose View has no account, no analytics, no advertising, and no tracking, and it doesn't send your readings or settings over the network. Five Lakes Studio never receives your health data.
e. Sharing. Glucose View doesn't share, sell, or disclose your health data to anyone. Health data is never used for advertising, marketing, or data mining, and is never stored in iCloud by Glucose View.
f. Retention. Because your readings exist only on your iPhone, Five Lakes Studio retains none of them. Glucose View keeps its copy until you delete the app or use Re-import from Apple Health in Settings. When you delete a reading in Apple Health, Glucose View removes it from its copy the next time it syncs.
g. Your choices. You can turn off Glucose View's access at any time in the Health app or in Settings, under Privacy & Security, then Health. Deleting the app removes its copy of your readings and its settings from your iPhone. Your readings in Apple Health aren't affected. Because we never receive your data, we can't access, recover, or delete it for you.
h. Apple Health. Apple Health manages its own data, including any iCloud syncing you've turned on in Health. That is covered by Apple's privacy policy, not this one.
i. Not medical advice. Glucose View is for informational purposes only and is not a medical device. Five Lakes Studio is not a healthcare provider.
We don't knowingly collect personal information from children under 13. If you believe a child has sent us personal information, such as by email, contact us and we'll delete it.
We take reasonable steps to protect the limited information we receive, such as support emails. Information stored on your device is protected by your device's own security, including your passcode.
You can ask us what personal information we hold about you, such as support emails, and ask us to correct or delete it, by contacting us at the address below. Information that exists only on your device is under your control, and we can't access it.
Our Website and Apps rely on services operated by others, including Apple, Cloudflare, and Google. Those companies handle information under their own privacy policies, and we aren't responsible for their practices. Links to other websites are provided for convenience and are governed by those sites' policies.
We may update this Privacy Policy from time to time, including as our Website and Apps change. When we do, we'll post the updated policy on this page and change the effective date above. If an App update changes what that App collects or how it uses information, we'll update the App's section and its App Store privacy details no later than when the update is released. We won't use information we've already received in a materially different way without your consent where the law requires it. Continuing to use the Website or an App after an update takes effect means you accept the updated policy.
Questions or requests about this Privacy Policy can be sent to Five Lakes Studio LLC at [email protected].
Effective October 6, 2026. Replaces the policy dated June 26, 2013.
