Your privacy is important to us. This Privacy Policy explains how JuiceMojo ("the app", "we", "us", "our") collects, uses, stores, and protects your data when you use the JuiceMojo mobile application and our associated services.
1. Information We Collect
JuiceMojo is designed to provide you with a personalized experience, whether you use the app as an anonymous guest or as a registered user. We collect the following categories of information:
- Temporary Anonymous Identifiers (Guest Users): To allow you to use the app without registering, we create an anonymous guest session protected with a secure JSON Web Token (JWT). This lets you build and save recipes before you ever create an account.
- Device Identifier: When you first open the app we generate a random, app-specific device identifier that is stored on your device and sent with your requests. We use it only to enforce free-tier usage limits (for example, the number of free AI recipe generations) and to prevent abuse such as repeatedly creating new accounts to bypass those limits. This identifier is not the advertising identifier (IDFA), is not used for advertising, and is reset if you delete and reinstall the app.
- Account and Profile Data: If you choose to register a permanent account, we store your username and a securely hashed version of your password, along with your chosen display name. If you instead use Sign in with Apple, we store the identifier Apple provides and, if you authorize it, the email address Apple shares with us — which may be a private Apple relay address rather than your real email. If you upgrade from a guest account, we automatically merge your temporary guest data into your new permanent profile.
- User Configurations and Settings: We store your personalized overrides in our secure database (Azure SQL), including custom ingredient yields, ingredient prices (internally stored in USD), category memberships, cleaning difficulties, customized recipe yields, and your language and theme preferences.
- Recipes and Brewing History: We store the custom recipes you create, alongside historical snapshots of your active and completed juicing rounds (batches) so they remain unaffected by future catalog updates.
- Messages You Send Us: If you contact us through the in-app contact form or messaging feature, we store the content of those messages so we can respond and provide support.
- AI Usage Records: Each time you use an AI feature, we record a usage entry containing the AI provider used, the outcome, processing time, a timestamp, and your user and device identifiers. We use this strictly to enforce usage quotas, detect abuse, and monitor reliability.
- Technical Logs: We collect error logs and system performance data (via Azure Log Analytics) to help us troubleshoot technical issues and maintain app stability. These logs may include a user or device identifier for the duration needed to diagnose a problem. We do not record your IP address in these logs.
2. How We Use Your Information
We use your data strictly to deliver and improve the functional features of the app, including:
- Calculating accurate nutrition profiles and daily intake percentages based on your selected ingredients.
- Calculating estimated costs per glass using your custom price overrides mapped against current currency exchange rates.
- Synchronizing your saved recipes across multiple devices when you are securely logged in.
- Enforcing free-tier limits and preventing abuse of our service.
A Note on Nutritional Data: All nutrition calculations, vitamin profiles, and dietary metrics in JuiceMojo are provided purely as estimates for informational purposes. The app does not track medical health records and does not share your data with external medical or health platforms (such as Apple Health).
3. Data Sharing and Third-Party Services
We never sell your personal information to advertisers or external commercial companies. However, to deliver specific app features, we securely coordinate with the following trusted third-party providers. We require these providers to protect your data and to use it only for the purposes described below.
AI-Generated Recipes ("Empty the Fridge" and AI Suggestions)
When you trigger the app's AI features, we send the information needed to generate a recipe to one of our AI processing providers (such as Anthropic Claude, OpenAI, or Google Gemini). Depending on the feature, this may include:
- the list of ingredients you select and your target juice volume (ml);
- your taste preferences (such as sweetness and sourness levels), preferred juicer type, and the number of ingredients; and
- your selected display language, so the recipe is returned in that language.
Important: We never transmit your name, email address, account identifier, or device identifier to these AI providers. The app does not offer a free-text prompt — you generate recipes only by choosing from predefined options (ingredients, categories, taste preferences, and volume), so no free-form text you type is ever sent to an AI provider.
Processing by these providers is also governed by their own privacy policies and API terms of service — we encourage you to review Anthropic's, OpenAI's, and Google's respective privacy documentation if you have questions about their individual data practices. JuiceMojo does not have direct technical control over how these providers handle data once it has been processed on their infrastructure; our ability to enforce restrictions is contractual, not technical.
These AI providers may process this data on servers located outside the European Economic Area (for example, in the United States). See International Data Transfers below.
Payments and Subscriptions (Apple StoreKit)
All monthly and yearly premium subscription purchases are managed exclusively by Apple through their official payment framework (StoreKit).
- JuiceMojo never views, accesses, or stores your credit card numbers, billing addresses, or banking details.
- Apple transmits only an anonymized, cryptographically signed transaction token (including an
OriginalTransactionId) to our backend servers so we can verify whether your Premium entitlement is active.
4. Tracking and Advertising
JuiceMojo does not track you across apps or websites owned by other companies, does not use the Apple advertising identifier (IDFA), and does not display third-party advertising. Because we do not track you in this way, the app does not present the App Tracking Transparency prompt. The identifiers we use (described in Section 1) are used solely to operate the app's own features and limits.
5. International Data Transfers
Your account data and recipes are housed on cloud infrastructure located in Europe (Microsoft Azure). However, some features rely on providers located outside the European Economic Area — in particular, the AI providers described in Section 3, which may process your request in the United States. Where data is transferred internationally, we rely on the relevant provider's safeguards (such as Standard Contractual Clauses or equivalent mechanisms) to protect it.
6. Data Security
All communication between the mobile application on your phone and our API infrastructure is strictly encrypted using HTTPS. Passwords are stored only in securely hashed form, and access to user sessions is governed by short-lived JSON Web Tokens (JWT) to safeguard your account against unauthorized entry.
7. Data Retention
- Account, profile, configuration, and recipe data is retained for as long as your account exists, and is deleted when you delete your account (see Section 8).
- Technical logs and AI usage records are retained for a limited period needed for troubleshooting, reliability monitoring, and abuse prevention, after which they are deleted or anonymized.
- Guest data that is never linked to a permanent account may be removed after a period of inactivity.
8. Your Rights and Data Deletion
You retain the right to request access to the data we store about you, to request corrections to any inaccuracies, to request a copy of your data in a portable format, and to object to certain processing.
In strict compliance with Apple's app guidelines, you also hold the absolute right to delete your user account permanently. You can initiate a complete account erasure directly from the Profile screen within the app, or by contacting us. Upon deletion, your account identifiers, email address (if any), custom configurations, and all saved recipes are removed permanently from our active databases.
If you are located in the European Economic Area or the United Kingdom, you also have the right to lodge a complaint with your local data protection supervisory authority.
9. Children's Privacy
JuiceMojo is not directed to children under the age of 13 (or under 16 in regions where that is the applicable minimum age), and we do not knowingly collect personal information from children. If you believe a child has provided us with personal information, please contact us so we can delete it.
10. Changes to This Policy
We may update this Privacy Policy from time to time to reflect changes in our app or legal requirements. When we make material changes, we will update the "Last updated" date above and, where appropriate, notify you within the app. Your continued use of JuiceMojo after an update constitutes acceptance of the revised policy.
11. Contact Us
If you have any questions regarding this Privacy Policy or wish to exercise your data rights, you can reach us through the in-app contact form or by email at northendlinkapps@gmail.com.
