Last updated: April 17, 2026
Summary of key points
User Information
User authentication is provided by Clerk, which acts as an independent data controller for authentication-related personal data. While Clerk manages login credentials and authentication workflows, we may access limited account information such as email addresses when necessary to operate, manage, and support the Service. Any authentication-related personal data is processed in accordance with Clerk’s privacy policy and applicable data protection laws, including the General Data Protection Regulation (GDPR).
Sensitive data
We do not process sensitive personal information.
Third parties
We do not collect information from third parties. Flashcard content (words and translations) is processed by Google in two ways: (1) via the Gemini API to provide AI import features, and (2) via the Google Cloud Text-to-Speech API to generate audio pronunciation when you use the audio feature. Optional analytics are provided by Google Analytics. Payment data (tips) is handled by Buy Me a Coffee.
Your rights
Depending on your location, you may access, correct, or delete your data. Contact us at [email protected].
IMPORTANT DISCLAIMER
THE FLASHCARDS ARE NOT ENCRYPTED. FLASHCARD CONTENT (WORDS AND TRANSLATIONS) IS SENT TO GOOGLE'S GEMINI API WHEN USING THE AI IMPORT FEATURE, AND TO GOOGLE'S CLOUD TEXT-TO-SPEECH API WHEN USING THE AUDIO PRONUNCIATION FEATURE. DO NOT ENTER PERSONAL OR SENSITIVE INFORMATION INTO THESE CARDS, MANUALLY OR VIA THE AI TOOL.

1. What information do we collect?

Personal information you disclose to us

In short: We collect limited personal information from you.

We do not directly manage passwords or authentication credentials required for account login. User authentication is handled by Clerk, which processes necessary authentication data independently. However, we may access limited personal information, such as email addresses, where necessary for account management, service operation, or user support.

Sensitive information. We do not process sensitive information.

Payment data. All payment data is handled and stored by Buy Me a Coffee. You may find their privacy notice at https://buymeacoffee.com/privacy-policy.

Authentication Data. If you choose to register or log in, authentication is handled via Clerk. While Clerk manages login credentials and authentication workflows, we may access limited profile information such as your email address for account administration and service functionality. Any additional profile data is processed directly by Clerk and/or the relevant identity provider in accordance with their respective privacy policies. You can review Clerk’s privacy policy here: https://clerk.com/legal/privacy.

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 process limited user-provided content (such as flashcards and related data) solely to operate and provide the core functionality of the Services. This data is stored in our database infrastructure (Neon) and is not used for analytics, marketing, or profiling purposes. We do not collect or process personal identifiers; authentication and identity-related data are handled exclusively by Clerk.

Where you use AI-powered features, the text content of your flashcards (words and translations) is transmitted to Google's Gemini API for processing. Google acts as a data processor in this context. This data is subject to Google's API Terms of Service and Data Processing Addendum. We recommend you do not enter personal or sensitive information into your flashcards.

Where you use the audio pronunciation feature, the word text of individual flashcards is transmitted to Google's Cloud Text-to-Speech API to generate an audio file. This transmission occurs server-side (from our backend to Google's API); the audio is then returned to your browser as a base64-encoded MP3. Google processes this data solely to synthesise and return the requested audio. This data is subject to Google Cloud's Terms of Service and Privacy Notice. No user identifiers are included in TTS requests.

3. What legal bases do we rely on to process your information?

In short: We only process your personal information when we believe it is necessary and we have a valid legal reason to do so under applicable law.

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

The 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:

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) to use your personal information for a specific purpose, or in situations where your permission can be inferred (implied consent). You can withdraw your consent at any time.

4. When and with whom do we share your personal information?

In short: We may share information in specific situations described in this section and/or with the following third parties.

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.

When you consent to analytics cookies, we use Google Analytics, which sets cookies to collect usage data. You can withdraw this consent at any time by clicking "Cookie settings"

6. How do we handle your social logins?

In short: Authentication is handled by a third-party provider and we do not access your personal data.

Our Services use Clerk to manage login and account authentication. If you choose to sign in via a third-party provider (such as Google), personal information related to authentication is processed directly by Clerk and the respective provider. While we do not manage login credentials, we may access limited account information such as email addresses where necessary to operate and support the Service. We recommend reviewing the privacy policies of both Clerk and your chosen identity provider to understand how your data is handled.

7. How long do we keep your information?

In short: We keep your information for as long as necessary to fulfil 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. No purpose in this notice will require us keeping your personal information for longer than the period of time in which users have an account with us.

When we have no ongoing legitimate business need to process your personal information, we will either delete or anonymise such information, or securely store your personal information and isolate it from any further processing until deletion is possible.

8. How do we keep your information safe?

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

We have implemented appropriate and reasonable technical and organisational security measures designed to protect the security of any personal information we process. However, no electronic transmission over the Internet or information storage technology can be guaranteed to be 100% secure. You should only access the Services within a secure environment.

9. What are your privacy rights?

In short: Depending on your location, 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 to:

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.

Upon your request to terminate your account, we will deactivate or delete your account and information from our active databases.

If you have questions or comments about your privacy rights, you may email us at [email protected].

10. Controls for Do-Not-Track features

Most web browsers and some mobile operating systems 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 recognising and implementing DNT signals has been finalised. As such, we do not currently respond to DNT browser signals. 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.
