Privacy Policy
Last updated: 2026 · How Elufi collects, uses, and protects your information
1. Introduction
This Privacy Policy explains how Elufi (“the App”) collects, uses, and protects your information when you use the Elufi mobile application.
Elufi is designed as a calm and supportive food companion that helps users build healthier eating habits without pressure.
The application, and the data controller responsible for your personal information under this Policy, is:
- Marek Chowaniec — Poland
- Email: support@elufi.app
This Privacy Policy applies globally to all users of the Elufi application.
2. Information We Collect
Account information. When you create an account in Elufi, we may collect:
- Email address
- Authentication information from login providers such as Apple, Google, or Facebook
- Unique identifiers generated by authentication systems
This information is used solely to enable secure authentication and provide access to your account.
Information stored locally on your device. Most personal data used by Elufi is stored locally on your device and is not transmitted to our servers. This may include:
- Name
- Weight and height
- Nutrition or lifestyle goals
- Meal history
- Personal notes
- Daily progress information
This data remains under your control and is stored locally unless a specific feature requires synchronization.
Analytics information. Elufi uses Google Analytics for Firebase to better understand how users interact with the application and to improve its functionality, stability, and user experience. Analytics information may include device type and model, operating system, application usage events, country or time zone, and crash reports or diagnostic data. This information is collected in aggregated form and does not directly identify individual users.
Push notifications. Elufi may use Firebase Cloud Messaging to deliver optional notifications such as reminders, motivational messages, and app updates. Push notifications are optional and can be disabled at any time in your device settings.
Advertising. Elufi may display advertisements through Google advertising services such as Google AdMob. Advertising partners may collect limited technical information such as device identifiers or advertising IDs in order to display relevant advertisements.
3. Cookies and Tracking Technologies
The Elufi mobile application does not use browser cookies. Instead, it may rely on device-level identifiers (such as advertising IDs) for the analytics and advertising purposes described above. You can reset or limit these identifiers at any time through your device's privacy settings, and you can opt out of personalized advertising through your device's ad settings (for example, "Opt out of Ads Personalization" on iOS and Android).
Our website (elufi.app) uses only essential technologies required to display the site correctly, such as loading web fonts. It does not use advertising or third-party tracking cookies.
4. How We Use Information
Information collected through the application may be used to:
- Provide and maintain the application
- Enable account authentication and login
- Improve application performance and stability
- Understand how users interact with the app
- Deliver optional notifications
- Support subscription services through app stores
- Ensure security and prevent misuse
Elufi does not sell personal data to third parties.
5. Legal Basis for Processing (GDPR)
If you are located in the European Economic Area (EEA), we process personal data based on the following legal grounds:
- Providing the Elufi service to users (performance of a contract)
- Your consent, where required, for example for optional notifications or advertising
- Legitimate interests, such as improving the application and keeping it secure
- Compliance with legal obligations
Where processing is based on consent, you may withdraw that consent at any time through your device or account settings, without affecting the lawfulness of processing carried out before withdrawal.
6. Data Storage
Most personal information used by Elufi is stored locally on the user's device. Account authentication data may be processed through trusted third-party services such as Firebase Authentication.
7. Data Retention
We retain personal information only for as long as necessary to provide the service or comply with applicable legal obligations. Analytics data may be stored in aggregated form for service improvement purposes. When you delete your account, we delete the associated authentication data and server-side identifiers as described in Section 10.
8. Your Privacy Rights
Depending on your location, you may have certain privacy rights, including the right to:
- Access your personal data
- Correct inaccurate information
- Request deletion of your data
- Restrict or object to certain processing activities
- Request data portability
- Lodge a complaint with your local data protection authority
To exercise any of these rights, please contact support@elufi.app.
9. California Privacy Rights (CCPA)
If you are a California resident, you have the right to request details about the personal information we hold about you and to request its deletion, using the same contact method above. Elufi does not sell or share personal information for cross-context behavioral advertising in the sense defined by the CCPA.
10. Account Deletion
Users can delete their account directly within the application. When an account is deleted, authentication data is removed and any associated server-side identifiers are deleted. Locally stored information may remain on the device until the application is removed. For step-by-step instructions, including how to request deletion if you no longer have the app installed, see our Delete Account page.

14. Data Security
We take reasonable technical and organizational measures to protect user data from unauthorized access, loss, misuse, and alteration. However, no digital system can guarantee absolute security.
