Privacy Policy

glucosensei.com

Effective Date: March 14, 2026 | Last Updated: June 16, 2026

Your privacy matters. This Privacy Policy explains what information is collected when you visit glucosensei.com and when you use the GlucoSensei mobile app, why it is collected, how it is used, and your rights under Canada’s Personal Information Protection and Electronic Documents Act (PIPEDA). By using this website or the GlucoSensei app, you agree to the practices described in this policy.

1. Who We Are

This website and the GlucoSensei mobile app are operated by glucosensei.com. For any privacy-related questions or requests, you can reach us at:

📧 Email: support@glucosensei.com
🌐 Website: https://glucosensei.com

2. GlucoSensei Mobile App

This section describes how the GlucoSensei mobile app handles your information. The remaining sections describe the glucosensei.com website. Where they differ, this section governs the app.

2.1 What the App Collects and Where It Goes

GlucoSensei is built to keep your health information on your device. The app has no user accounts, and it does not collect your name or email.

Glucose readings, meals, carbohydrate and nutrition entries, insulin doses, medications, and profile settings. Stored on your device in encrypted form. This information is sent to our server and our AI provider only when you choose to use Insights or Glucose Predictions.
Meal photos. Stored on your device. A photo is sent to our server and our AI provider only when you choose AI Meal Photo Analysis.
Subscription identifier. A RevenueCat customer ID generated for your installation, sent with AI requests so we can confirm your subscription is active.
Purchase history. Handled by Apple and RevenueCat through Apple’s In-App Purchase system.

The app does not use analytics, advertising, or tracking. We do not sell or share your information for advertising, and we do not link it to your activity on other companies’ apps or websites.

2.2 Who Processes Your Information

When you use an AI feature, the data for that feature is processed by:

Anthropic, PBC (United States), which generates the meal analysis, insight, or prediction. Anthropic processes the data only to return your result and does not use GlucoSensei data to train its models.
RevenueCat, Inc. (United States), which manages and verifies your subscription.
Vercel, Inc. (United States), which hosts the server that routes your AI request.
Apple, which processes in-app purchases.

When you search for foods, your search term, not your health data, is sent to the USDA FoodData Central database (United States) to look up nutrition information.

2.3 Storage Outside Canada

The service providers above are located in the United States. When you use an AI or food-search feature, the relevant information is processed in the United States and is subject to the laws of that country, including lawful access requests by U.S. authorities. If you do not use these features, your information stays on your device and is not transferred.

2.4 How Long We Keep It

Your logs and photos remain on your device until you delete them or use “Clear Data” in the app’s Settings. Data sent for an AI feature is processed in memory to produce your result and is not stored in our database. Information held by Anthropic, RevenueCat, and Apple is retained under their own data policies.

2.5 How We Protect It

Health information stored in the app is encrypted on your device using AES-256-GCM, with the encryption key held in the iOS Keychain (or Android Keystore). All data sent to our server travels over encrypted HTTPS connections.

3. What Information the Website Collects

3.1 Information You Provide Directly

On the glucosensei.com website, we do not currently collect personal information through forms or account registration. Subscriptions to the GlucoSensei mobile app are purchased through Apple’s In-App Purchase system, described in Section 2, not through this website. If we offer any purchase directly through the website, payment is handled by our payment processor, Stripe (see Section 5).

3.2 Information Collected Automatically

When you visit our website, certain information may be collected automatically, including:

Your IP address and approximate location (country/region)
Browser type and version
Pages visited and time spent on those pages
Referring website (how you found us)
Device type (desktop, mobile, tablet)

This information is collected on the website through cookies and analytics tools (see Sections 4 and 5). The mobile app does not collect this information.

If you make a purchase directly through this website, payment is processed securely through Stripe. We do not store your payment card details on our servers, and Stripe processes payment information in accordance with PCI-DSS standards.

5.3 MailerLite (Email Marketing)

If you subscribe to our email list, your name and email address will be stored with MailerLite, our email marketing platform. You can unsubscribe from marketing emails at any time by clicking the unsubscribe link in any email we send.

6. How We Use Your Information

We use the information collected for the following purposes:

To send you updates, newsletters, or promotional content (only if you have opted in)
To analyze website traffic and usage patterns so we can improve our content
To prevent spam, fraud, and other harmful activity
To comply with applicable laws and legal obligations

7. Who We Share Your Data With

We do not sell, rent, or trade your personal information. We may share your data only in the following circumstances:

With third-party service providers listed in Section 5 (Google Analytics, Stripe, MailerLite), solely to provide the services described. The mobile app’s service providers are listed in Section 2.
If required by law, regulation, or court order.
To protect the rights, safety, or property of glucosensei.com or its users.

Email list data: Retained in MailerLite until you unsubscribe or request deletion.
App health data: Stored on your device and retained until you delete it, as described in Section 2.

You may request deletion of your data at any time by contacting us at support@glucosensei.com.

9. Your Privacy Rights Under PIPEDA

As a resident of Canada, you have the following rights regarding your personal information:

Right to access: You may request a copy of the personal information we hold about you. Health information you enter in the app is stored on your device, so you can view it there at any time.
Right to correction: You may request that inaccurate or incomplete information be corrected. App data can be edited or deleted directly in the app.

10. Data Security

We take reasonable steps to protect your personal information from unauthorized access, use, or disclosure. Our website uses HTTPS encryption, the mobile app encrypts your health data on your device (see Section 2.5), and we work only with reputable third-party providers who maintain strong security standards.

However, no method of transmission over the internet is 100% secure. While we strive to protect your information, we cannot guarantee absolute security.

11. Children’s Privacy

This website and app are not intended for use by individuals under the age of 18. We do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us immediately at support@glucosensei.com.

12. Links to Other Websites

Our website may contain links to third-party websites. We are not responsible for the privacy practices of those sites and encourage you to review their privacy policies before providing any personal information.

13. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our practices or applicable laws. When we do, we will update the “Last Updated” date at the top of this page. We encourage you to review this policy periodically.

Your continued use of this website or the app after any changes constitutes your acceptance of the updated policy.
