Memocard.io Privacy Policy

Last updated: November 11, 2026

1. Introduction

Welcome to Memocard.io. We are committed to protecting our users' privacy and keeping your personal information secure. This privacy policy explains how we collect, use, disclose and protect your information when you use our mobile learning app and when you visit our website www.memocard.io (see section 2.C for the website). It is designed to meet legal requirements (including the GDPR) and the Google Play Developer Program Policies.

2. Data we collect

We collect different types of information to provide and improve our service, and to display relevant ads.

A. Data provided voluntarily by the user

To use certain features of the app, we ask you to provide:

• Username
• Email address (for authentication and account recovery)
• Learning content: Your study lists (flashcards), your scores and your progress.

B. Data collected automatically

When you access the app, some data is collected automatically, in particular through our advertising partners:

• Device data: Phone model, operating system version, unique device identifiers.
• Advertising identifiers: Google Advertising ID (GAID) on Android or IDFA on iOS.
• Usage data: Interactions with the app, crash logs and diagnostics.
• IP address: Used to determine general location (city/country level) for targeted advertising.

C. Data collected on www.memocard.io

The website and blog require no sign-up and have no forms, comments or ads. The only data processed is the following.

Audience measurement (Matomo, cookie-free)

To find out which pages are useful and improve the website, we use Matomo, an audience measurement tool hosted on our own servers, in France. No data is sent to Matomo or any other third party, and none is used for advertising or combined with other processing.

• No cookies: no analytics cookie is stored on your device.
• Anonymized IP address: the last two bytes are masked as soon as they are collected (for example 192.168.xxx.xxx). You cannot be identified.
• Data measured: pages viewed, visit duration, referring website or search engine, device type, browser, operating system, language, approximate country, and certain actions on the website (clicks to the App Store, Google Play or sign-up, use of the mini-quiz, FAQ questions opened, article reading).
• Retention period: raw visit data is automatically deleted after 25 months. Only aggregated, anonymous statistics are kept beyond that.
• Legal basis: our legitimate interest in measuring the website's audience. This setup follows the conditions set by the CNIL (the French data protection authority) for audience measurement tools exempt from consent.

You can still opt out of being counted in the statistics at any time, using the box below. Your browser will remember your choice.

Opt-out complete; your visits to this website will not be recorded by the Web Analytics tool. Note that if you clear your cookies, delete the opt-out cookie, or if you change computers or Web browsers, you will need to perform the opt-out procedure again.

You may choose to prevent this website from aggregating and analyzing the actions you take here. Doing so will protect your privacy, but will also prevent the owner from learning from your actions and creating a better experience for you and other users.

You are not opted out. Uncheck this box to opt-out. You are currently opted out. Check this box to opt-in.

The tracking opt-out feature requires cookies to be enabled.

"Download the app" banner

On mobile, if you close the banner suggesting you download the app, your choice is saved in your browser's local storage so that it doesn't reappear right away. This information stays on your device and is not sent to us.

Fonts

The website uses the Sora and Caveat fonts, loaded from the Google Fonts service. When this happens, your browser sends your IP address to Google's servers, as with any content loaded from another website. We do not use this service to track you.

Hosting

The website is hosted in France by o2switch (Clermont-Ferrand). Like any web server, it keeps technical logs (IP address, date, page requested) used for security and to keep the service running properly.

3. How we use data

We use your data for the following purposes:

1. Providing the service: Managing your account, saving your study lists and syncing your progress.
2. Improving the app: Analyzing bugs and optimizing the user experience.
3. Communication: Informing you of important updates (we don't send spam).
4. Advertising (New): Displaying banner or interstitial ads through Google AdMob/AdSense to fund the app's development.

4. Advertising and Sharing with Third Parties

To keep Memocard.io free (or partly free), we use third-party advertising services.

Google AdMob & AdSense

We use Google AdMob to serve ads. Google may use your device's advertising identifier, your approximate location and other usage data to provide:

• Personalized ads: Based on your interests and browsing history.
• Non-personalized ads: Based on the context of the app.

Google acts as a third-party data processor. To learn more about how Google uses your data, please see: How Google uses information from sites or apps that use its services.

We do not sell your personal data (email, name) to third parties.

5. Data retention

• Account data: We keep your email, username and lists for as long as your account is active.
• Deletion: If you delete your account, this data is erased from our servers (unless we are legally required to keep it).

6. Data protection

We implement reasonable technical and organizational security measures (encryption, restricted access) to protect your data against loss, misuse and unauthorized access. However, no method of transmission over the Internet is 100% secure.

7. Your Rights (GDPR and others)

You have the following rights regarding your data:

• Right of access and rectification: You can view and edit your information directly in the app.
• Right to erasure: You can request the complete deletion of your account and your data by contacting us.
• Right to object: You can choose not to receive personalized ads through your device settings (Android: Settings > Google > Ads). On the website, you can opt out of audience measurement using the box in section 2.C.
• Complaints: if you believe your rights are not being respected, you can contact the CNIL (www.cnil.fr).

8. Children's privacy

Our app is intended for a general audience ("All ages"), but we do not knowingly collect personal data from children under 13 (or the age of digital consent in your country) without verifiable parental consent. If we discover that we have collected data from a child without such consent, we will take steps to delete that information.

9. Changes to this policy

We may update this privacy policy from time to time. In the event of a significant change, we will notify you through a notification in the app or by email.
