Payment Data. We may collect data necessary to process your payment if you choose to make purchases, such as your payment instrument number and the security code associated with your payment instrument. All payment data is handled and stored by our third-party payment processors (such as Apple In-App Purchase). You may find their privacy notice at https://www.apple.com/legal/privacy.

Social Media Login Data. We may provide you with the option to register using your existing social media account details (like Apple ID or Google). If you choose to register this way, we will collect certain profile information from the social media provider, as described in section 7 below.

Application Data. If you use our application(s), we also may collect the following information if you choose to provide us with access or permission:

Geolocation Information. We may request access or permission to track location-based information from your mobile device to provide certain location-based services (e.g., store-finder features). If you wish to change our access or permissions, you may do so in your device's settings.

Information automatically collected

In Short: Some information — such as your Internet Protocol (IP) address and/or browser and device characteristics — is collected automatically when you visit our Services.

We automatically collect certain information when you visit, use, or navigate the Services.

Demographic and Shopping Data (Onboarding)

During onboarding, we may invite you to voluntarily provide additional demographic information — such as household size, age range, and region — and shopping habits data. This data is used to generate regional price KPIs and improve personalized recommendations. Providing this information is entirely optional and does not affect access to core features of the App.

All personal information that you provide to us must be true, complete, and accurate, and you must notify us of any changes to such personal information.

2. HOW DO WE PROCESS YOUR INFORMATION?

In Short: We process your information to provide, improve, and administer our Services, communicate with you, for security and fraud prevention, and to comply with law. We may also process your information for other purposes only with your prior explicit consent.

To generate anonymized, aggregated B2B analytics.

3. WHAT LEGAL BASES DO WE RELY ON TO PROCESS YOUR PERSONAL INFORMATION?

In Short: We only process your personal information when we believe it is necessary and we have a valid legal reason (i.e., legal basis) to do so under applicable law.

If you are located in the EU or UK, this section applies to you.

The General Data Protection Regulation (GDPR) and UK GDPR require us to explain the valid legal bases we rely on in order to process your personal information. We may rely on the following legal bases:

Consent. We may process your information if you have given us permission to use your personal information for a specific purpose. You can withdraw your consent at any time.
Performance of a Contract. We may process your personal information when we believe it is necessary to fulfill our contractual obligations to you, including providing our Services.
Legitimate Interests. We may process your information when we believe it is reasonably necessary to achieve our legitimate business interests and those interests do not outweigh your interests and fundamental rights and freedoms. For example, we may process your personal information to:

- Analyze how our Services are used so we can improve them to engage and retain users

Legal Obligations. We may process your information where we believe it is necessary for compliance with our legal obligations.
Vital Interests. We may process your information where we believe it is necessary to protect your vital interests or the vital interests of a third party.

If you are located in Canada, this section applies to you.

We may process your information if you have given us specific permission (express consent) or in situations where your permission can be inferred (implied consent). You can withdraw your consent at any time.

In some exceptional cases, we may be legally permitted under applicable law to process your information without your consent, including for investigations and fraud detection, business transactions, legal compliance, or other purposes permitted by applicable Canadian law.

In Short: We may share information in specific situations described in this section.

We may need to share your personal information in the following situations:

Business Transfers. We may share or transfer your information in connection with, or during negotiations of, any merger, sale of company assets, financing, or acquisition of all or a portion of our business to another company.

You may revoke your consent at any time by contacting us. For more information, please visit the Google Privacy & Terms page.
Affiliates. We may share your information with our affiliates, in which case we will require those affiliates to honor this Privacy Notice.
Business Partners (B2B — Anonymized Data Only). We share only anonymized, aggregated statistical datasets with our business partners (FMCG brands, retailers, market research firms). These datasets contain no personally identifiable information — no names, email addresses, device IDs, or other identifiers. You may opt out of contributing to these datasets at any time in Settings → Privacy → Data Sharing. Opting out does not affect your access to the App.
Service Providers. We may share your data with third-party vendors and service providers that perform services for us or on our behalf (hosting, analytics, push notifications, etc.), subject to data processing agreements.
Other Users. When you share personal information publicly within the Services (e.g., shared grocery lists), such personal information may be viewed by other users.

We do not sell, rent, or trade your personal data to any third party for their own marketing purposes.

5. DO WE USE COOKIES AND OTHER TRACKING TECHNOLOGIES?

In Short: We may use cookies and other tracking technologies to collect and store your information.

We may use cookies and similar tracking technologies (like web beacons and pixels) to gather information when you interact with our Services. Some online tracking technologies help us maintain the security of our Services and your account, prevent crashes, fix bugs, save your preferences, and assist with basic site functions.

We also permit third parties and service providers to use online tracking technologies on our Services for analytics and advertising, including to help manage and display advertisements, to tailor advertisements to your interests, or to send abandoned cart reminders.

Google Analytics

We may share your information with Google Analytics to track and analyze the use of the Services. To opt out of being tracked by Google Analytics, visit https://tools.google.com/dlpage/gaoptout. For more information on the privacy practices of Google, please visit the Google Privacy & Terms page.

Specific information about how we use such technologies and how you can refuse certain cookies is set out in our Cookie Notice.

6. DO WE OFFER ARTIFICIAL INTELLIGENCE-BASED PRODUCTS?

In Short: We offer products, features, or tools powered by artificial intelligence, machine learning, or similar technologies.

As part of our Services, we offer products, features, or tools powered by artificial intelligence, machine learning, or similar technologies (collectively, "AI Products"). These tools are designed to enhance your experience and provide you with innovative solutions. The terms in this Privacy Notice govern your use of the AI Products within our Services.

Use of AI Technologies

We provide AI Products through third-party service providers ("AI Service Providers"), including Google Cloud AI. Your input, output, and personal information will be shared with and processed by these AI Service Providers to enable your use of our AI Products. You must not use the AI Products in any way that violates the terms or policies of any AI Service Provider.

Our AI Products

Our AI Products are designed for the following functions:

Product recognition and categorization from shopping lists
Regional price analysis and smart recommendations

How We Process Your Data Using AI

All personal information processed using our AI Products is handled in line with our Privacy Notice and our agreement with third parties. This ensures high security and safeguards your personal information throughout the process.

In Short: If you choose to register or log in to our Services using a social media account, we may have access to certain information about you.

Our Services offer you the ability to register and log in using your third-party social media account details (like your Apple ID or Google account). Where you choose to do this, we will receive certain profile information about you from your social media provider. The profile information we receive may vary depending on the social media provider concerned, but will often include your name, email address, and profile picture, as well as other information you choose to make public.

We will use the information we receive only for the purposes described in this Privacy Notice. We do not control, and are not responsible for, other uses of your personal information by your third-party social media provider. We recommend that you review their privacy notice to understand how they collect, use, and share your personal information.

8. HOW LONG DO WE KEEP YOUR INFORMATION?

In Short: We keep your information for as long as necessary to fulfill the purposes outlined in this Privacy Notice unless otherwise required by law.

We will only keep your personal information for as long as it is necessary for the purposes set out in this Privacy Notice, unless a longer retention period is required or permitted by law (such as tax, accounting, or other legal requirements). No purpose in this notice will require us keeping your personal information for longer than twelve (12) months past the termination of the user's account.

When we have no ongoing legitimate business need to process your personal information, we will either delete or anonymize such information, or, if this is not possible (for example, because your personal information has been stored in backup archives), then we will securely store your personal information and isolate it from any further processing until deletion is possible.

Anonymized and aggregated data (such as market intelligence outputs) has no retention limit, as it cannot be linked back to any individual.

9. HOW DO WE KEEP YOUR INFORMATION SAFE?

In Short: We aim to protect your personal information through a system of organizational and technical security measures.

We have implemented appropriate and reasonable technical and organizational security measures designed to protect the security of any personal information we process, including:

Encryption in transit (TLS/HTTPS) and at rest
Access controls limiting who within our team can access personal data
Regular security reviews and vulnerability assessments

However, despite our safeguards and efforts to secure your information, no electronic transmission over the Internet or information storage technology can be guaranteed to be 100% secure, so we cannot promise or guarantee that hackers, cybercriminals, or other unauthorized third parties will not be able to defeat our security and improperly collect, access, steal, or modify your information. Although we will do our best to protect your personal information, transmission of personal information to and from our Services is at your own risk. You should only access the Services within a secure environment.

10. WHAT ARE YOUR PRIVACY RIGHTS?

In Short: Depending on your state of residence in the US or in some regions, such as the European Economic Area (EEA), United Kingdom (UK), Switzerland, and Canada, you have rights that allow you greater access to and control over your personal information.

In some regions (like the EEA, UK, Switzerland, and Canada), you have certain rights under applicable data protection laws. These may include the right (i) to request access and obtain a copy of your personal information, (ii) to request rectification or erasure; (iii) to restrict the processing of your personal information; (iv) if applicable, to data portability; and (v) not to be subject to automated decision-making. In certain circumstances, you may also have the right to object to the processing of your personal information.

You can make such a request by contacting us using the contact details provided in section 15 below.

We will consider and act upon any request in accordance with applicable data protection laws.

If you are located in the EEA or UK and you believe we are unlawfully processing your personal information, you also have the right to complain to your Member State data protection authority or UK data protection authority.

If you are located in Switzerland, you may contact the Federal Data Protection and Information Commissioner. If you are located in Luxembourg, you may contact the Commission Nationale pour la Protection des Données (CNPD).

Withdrawing your consent: If we are relying on your consent to process your personal information, you have the right to withdraw your consent at any time by contacting us using the details in section 15 below.

Opting out of marketing and promotional communications: You can unsubscribe from our marketing and promotional communications at any time by clicking on the unsubscribe link in the emails that we send, or by contacting us using the details provided in section 15 below. You will then be removed from the marketing lists. However, we may still communicate with you — for example, to send you service-related messages necessary for the administration and use of your account.

Opting out of B2B data aggregation: You can opt out of contributing your shopping and pricing data to our anonymized market intelligence datasets at any time in Settings → Privacy → Data Sharing. This does not affect your access to any feature of the App.

Upon your request to terminate your account, we will deactivate or delete your account and information from our active databases. However, we may retain some information in our files to prevent fraud, troubleshoot problems, assist with any investigations, enforce our legal terms and/or comply with applicable legal requirements.

If you have questions or comments about your privacy rights, you may email us at support@listeur.app.

11. CONTROLS FOR DO-NOT-TRACK FEATURES

Most web browsers and some mobile operating systems and mobile applications include a Do-Not-Track ("DNT") feature or setting you can activate to signal your privacy preference not to have data about your online browsing activities monitored and collected. At this stage, no uniform technology standard for recognizing and implementing DNT signals has been finalized. As such, we do not currently respond to DNT browser signals or any other mechanism that automatically communicates your choice not to be tracked online. If a standard for online tracking is adopted that we must follow in the future, we will inform you about that practice in a revised version of this Privacy Notice.

Global Privacy Control: We recognize and honor Global Privacy Control (GPC) signals. If you use a browser or extension that supports GPC, we will treat this as a valid request to opt out of the sale or sharing of your personal information for targeted advertising purposes under applicable state privacy laws. When we detect a GPC signal from your browser, we will automatically apply your opt-out preference without requiring you to take any additional action. For more information, visit globalprivacycontrol.org.
