Privacy Policy

Last updated: May 17, 2026

GluNudge is a lifestyle app that helps people understand meals from photos, simple nutrition estimates, and optional Meal Posters. This Privacy Policy explains what information we collect, how we use it, when we share it, and the choices you have about your information.

1. Information We Collect

We collect information you provide directly, information created when you use the app, and limited technical information that helps us operate and improve the service.

Account and auth information

If you sign in or restore access, we may collect information such as your Apple account identifier, email address, basic profile details, subscription status, and app authentication tokens used to keep your session active.

Meal, reading, and app content

We store meal photos, nutrition estimates, food-quality signals, meal history, optional reading logs, preferences, and any notes or feedback you choose to add. By default, saved app content stays on your device unless you enable iCloud sync or request cloud-based analysis.

Optional health and activity data

If you grant permission, GluNudge may read limited Apple Health data, such as daily step count, to show activity context. GluNudge does not write data to Apple Health.

Device, notification, and support data

We may collect limited technical data such as device type, operating system, app version, notification device tokens, backend usage records, and diagnostics you choose to include with support requests.

2. How We Use Information

We use information to provide the GluNudge service, support users, and improve the app over time.

To analyze meal photos and generate nutrition-related estimates, summaries, and optional Meal Posters.
To save your history, preferences, and account settings.
To operate, secure, maintain, and troubleshoot the app.
To understand service usage, maintain AI access, manage subscriptions, and improve reliability.
To respond to support requests, questions, and feedback.
To comply with legal obligations and enforce our terms and policies.

3. How Meal Photos, Posters, and Nutrition Estimates Are Handled

Meal photos and the resulting estimates are core to the product. Saved meal history, nutrition estimates, food-quality signals, and logged readings are stored on your device by default. If you enable sync, that saved app data is also synced to your private iCloud account through Apple's CloudKit service.

When you request AI analysis or poster generation, the selected meal photo and related request data are sent to GluNudge's backend, which runs on Cloudflare infrastructure. To provide the requested result, GluNudge may temporarily store the image and job data in Cloudflare, send the meal photo and request context to OpenAI, and store the returned analysis or poster result for a limited time so the app can retrieve it.

AI analysis and poster job records currently expire after about 72 hours. Uploaded images are retained temporarily according to our configured storage lifecycle, and signed image links used for processing are short-lived.

GluNudge is designed as a lifestyle product. The app is not intended to provide medical advice, diagnosis, or treatment, and nutrition outputs should be understood as estimates rather than guaranteed clinical measurements.

4. When We Share Information

We do not sell your personal information. We may share information only in limited situations such as the following:

With Apple services you choose or use, such as iCloud/CloudKit sync, Apple Health permissions, Sign in with Apple, StoreKit subscriptions, and Apple Push Notification service.
With Cloudflare and other infrastructure providers that help us host, secure, queue, store, and operate the app backend.
With OpenAI when you request AI meal analysis or poster generation.
With support providers or authorized personnel when needed to respond to support requests you submit.
If we offer sharing features and you choose to use them, with the people you choose and only according to the sharing controls shown in the app.
When required by law, regulation, legal process, or valid government request.
To protect the rights, safety, security, and integrity of GluNudge, our users, or the public.
As part of a merger, acquisition, financing, or sale of assets, subject to appropriate safeguards.

5. Retention

We keep information for as long as reasonably necessary to provide the service, maintain your account, meet legal obligations, resolve disputes, and enforce our agreements. Retention periods vary depending on the type of information and how it is used.

Meal history, readings, preferences, and synced app data remain on your device and, if enabled, in iCloud until you delete them or use in-app deletion controls.
AI analysis and poster job records, along with returned results, are retained for short operational periods, currently about 72 hours, so the app can retrieve results and troubleshoot failed jobs.
Images uploaded for AI analysis or poster generation are retained temporarily according to our configured storage lifecycle.
Account sessions, subscription records, notification tokens, support records, and security logs are retained as needed to operate, secure, and support the service.

6. Your Choices

You can choose whether to submit meal photos and other optional content.
You can choose whether to grant Apple Health access. You can change Health permissions in the Health app or iOS Settings.
You can manage device permissions, including camera, photo library, and notification access, in your device settings.
You can choose whether to enable or disable iCloud sync within the app.
You can access, export, or delete app data using controls provided in the app where available.
You can sign out of GluNudge account access and restore purchases through Apple and App Store flows.

7. Security

We use reasonable administrative, technical, and organizational safeguards designed to protect information. No system is perfectly secure, and we cannot guarantee absolute security.

8. Children's Privacy

GluNudge is not directed to children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information to us, please contact us so we can review and take appropriate action.

9. International Processing

Depending on where you use GluNudge, your information may be processed or stored in countries other than your own. Where required, we will use reasonable measures intended to protect information during those transfers.

10. Changes to This Policy

We may update this Privacy Policy from time to time. If we make material changes, we will update the effective date above and, where appropriate, provide additional notice.
