Privacy Policy — Crumbs

Last updated: 24 March 2026

Crumbs ("the App") is a food and symptom tracking application developed by Stalker Digital ("we", "us", "our"). This privacy policy explains how the App handles your data.

Data Storage

All personal data you enter into Crumbs — including food entries, symptom logs, medications, daily context, and condition preferences — is stored locally on your device only. We do not operate servers, databases, or cloud services that collect or store your data.

Your data never leaves your device unless you explicitly choose to export it using the App's export feature.

Data We Do Not Collect

  • We do not collect your name, email address, or any account information
  • We do not collect your health or dietary data
  • We do not track your location
  • We do not access your contacts, photos, or files
  • We do not create user accounts or require sign-in

Advertising

The App displays non-personalised banner advertisements provided by Google AdMob. AdMob may collect device identifiers and general device information for the purpose of serving ads. These ads are non-personalised, meaning they are not based on your personal data or browsing history.

For more information about how Google handles data, see Google's Privacy Policy.

You may remove all ads permanently through a one-time in-app purchase.

In-App Purchases

In-app purchases are processed by RevenueCat on behalf of the Apple App Store or Google Play Store. RevenueCat processes transaction data (purchase tokens and subscription status) to verify your purchase. RevenueCat does not receive any of your health or dietary data.

For more information, see RevenueCat's Privacy Policy.

Third-Party Services

The App uses the following third-party services:

| Service | Purpose | Data Accessed | |---------|---------|---------------| | Google AdMob | Non-personalised advertising | Device identifiers | | RevenueCat | In-app purchase verification | Purchase tokens | | Apple App Store / Google Play | App distribution and purchases | Standard store data |

No third-party service has access to the food, symptom, medication, or health data you enter into the App.

Data Export and Sharing

The App provides an export feature that allows you to save your data as a JSON file or generate a PDF report for your doctor. These files are created on your device and shared only through your device's standard sharing options (email, messaging, etc.). We have no access to exported files.

Children's Privacy

The App is not directed at children under 13. We do not knowingly collect data from children.

Medical Disclaimer

Crumbs is not a medical device and is not intended to diagnose, treat, cure, or prevent any disease or medical condition. The correlations and patterns shown in the App are based solely on data you enter and should not be considered medical advice. Always consult a qualified healthcare professional before making dietary or medical decisions.

Changes to This Policy

We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated revision date.
