1. What LingFlow Is

LingFlow is a digital language-learning website. We provide access to learning stories, audio practice, translations, vocabulary tools, and interactive exercises.

2. Information We Collect

We may collect the following types of information:

Account Information

When you create an account or request access, we may collect information such as:

email address;
account identifier;
login or authentication information;
subscription status.

Learning Activity

To provide the service, we may process learning-related data such as:

selected language;
learning progress;

vocabulary selections;
answers submitted in exercises;
usage of audio, translations, and learning tools.

approximate location based on IP address;
pages visited;
timestamps;
error logs;
performance and diagnostic data.

Payment Information

Payments are processed by our payment provider Paddle.

LingFlow does not store your full card number or full payment card details. Paddle may collect and process payment information, billing details, tax information, invoices, and transaction records according to its own policies and legal obligations.

3. How We Use Information

We use personal information to:

provide access to LingFlow;
manage accounts and subscriptions;
deliver learning content and exercises;
track learning progress;
improve the quality and reliability of the service;
provide customer support;
prevent fraud, abuse, and technical issues;
send service-related emails;
comply with legal, tax, accounting, and security obligations.

4. Legal Bases for Processing

Where applicable, we process personal information based on one or more of the following legal bases:

performance of a contract, when we provide the service you requested;
legitimate interests, such as improving the service, preventing abuse, and maintaining security;
consent, where required, for example for certain marketing or optional cookies;
legal obligations, where we must keep records or comply with applicable laws.

5. Cookies and Analytics

LingFlow may use cookies or similar technologies to keep the website working, remember preferences, improve performance, and understand how users interact with the service.

We use Google Ads conversion tracking to measure the effectiveness of our advertising. When you arrive at our site from a Google Ads click, your browser receives a click identifier (commonly known as gclid) which we store locally for up to 90 days. If you later sign up or make a purchase, this identifier may be shared with Google Ads so that the conversion can be attributed to the original ad click. This helps us understand which campaigns work and improve our advertising spend. No personal identifiers (email, name, payment data) are sent to Google through this mechanism. You can opt out of Google Ads personalization at any time at https://adssettings.google.com.

We also use Plausible Analytics, a privacy-focused, cookieless analytics service, to understand aggregate traffic patterns. Plausible does not collect personal data and does not set tracking cookies.

Where required by law, we will ask for consent before using non-essential cookies.

You can usually control cookies through your browser settings.

6. Email Communications

We may send service-related emails such as login links, account notices, payment notices, subscription updates, security messages, or important product changes.

We may send marketing emails only where allowed by law or with your consent. You can unsubscribe from marketing emails at any time.

7. Sharing Information with Third Parties

We may share personal information with trusted service providers that help us operate LingFlow, such as:

payment processors and merchant of record providers, including Paddle;
hosting and infrastructure providers;
email delivery providers;
analytics and diagnostics providers, including Plausible Analytics;
advertising platforms, including Google Ads (for conversion attribution as described in Section 5);
customer support tools;
security and fraud prevention services.

We only share information needed for these providers to perform their services.

We may also disclose information if required by law, court order, government request, or to protect the rights, safety, and security of LingFlow, users, or others.

8. International Transfers

LingFlow and its service providers may process information in different countries. Where required, we use appropriate safeguards to protect personal information transferred internationally.

9. Data Retention

We keep personal information only for as long as reasonably necessary to provide the service, comply with legal obligations, resolve disputes, prevent fraud, and enforce our agreements.

Account and learning data may be kept while your account is active. Some payment, tax, and transaction records may be kept longer where required by law.

10. Your Rights

Depending on your location, you may have rights to:

access your personal information;
correct inaccurate information;
request deletion of your information;
object to or restrict certain processing;
request a copy of your data;
withdraw consent where processing is based on consent;
file a complaint with a data protection authority.

To make a request, contact us at support@lingflow.me.

We may need to verify your identity before processing certain requests.

11. Security

We use reasonable technical and organizational measures to protect personal information. However, no online service can guarantee complete security.

You are responsible for keeping your account access secure.

12. Children

LingFlow is not intended for children under the age required by applicable law to use online services without parental consent.

If you believe a child has provided personal information without proper consent, please contact us and we will take appropriate action.
