Privacy Policy

Effective Date: 11/04/2026
This Privacy Policy describes how Leantyped B.V. ("we", "us"), registered in the Netherlands (KvK 80878245), collects, uses, and protects your personal data when you use wordholder.com and the Word Holder browser extension (together, the "Application").
Leantyped B.V. is the data controller for your personal data under the General Data Protection Regulation (GDPR).

1. What Data We Collect

• Account Data: If you sign in with Firebase, we receive a unique user ID and (if you provide it) your email address.
• Searched Words: When you look up a word, it is stored in Firebase under your account so you can review your search history.
• Log Data: Standard technical details such as IP address, browser type, and pages visited.
• Analytics: Google Analytics is used to understand how users interact with the Application. We send behavioural events such as page views, word lookups and quiz activity. These events do not include the words you look up. This may involve cookies and similar identifiers.
• Advertising & Conversion Measurement: Google Ads conversion tracking is used to measure the effectiveness of our advertising. When you sign in with an email address, a hashed (SHA-256) version of your email may be transmitted to Google Ads to improve conversion attribution ("Enhanced Conversions"). We do not transmit plain-text email addresses.

2. How We Use Your Data

• To provide and improve the Application.
• To let you access your personal search history.
• To analyze usage and improve features.
• To measure the effectiveness of our advertising campaigns.
• To ensure security and prevent abuse.

We never sell your data.

3. Legal Bases for Processing (GDPR)

• Contract: To provide you with access to the Application and your account.
• Legitimate Interest: To improve the Application and ensure security.
• Consent: Where required for analytics cookies.

4. Third-Party Services

• Firebase (Google LLC): Provides authentication, hosting, and database services. Data may be processed on servers outside the EU, with safeguards such as Standard Contractual Clauses.
• Google Analytics (Google LLC): Provides usage statistics. Analytics cookies may be stored in your browser.
• Google Ads (Google LLC): Used for advertising and conversion measurement. Ad cookies may be stored in your browser. If you sign in, a hashed (SHA-256) version of your email may be sent to Google Ads for Enhanced Conversion attribution. Plain-text email is never transmitted.

5. Browser Extension

The Word Holder browser extension allows you to look up word definitions directly from any webpage. The following applies specifically to the extension:

• Text Selection: The extension monitors your text selection solely to determine whether you have selected a single word. It does not read, collect, or transmit any page content.
• Word Lookups: When you right-click and choose to look up a word, only the selected word and the chosen language are sent to the Word Holder API to fetch the definition.
• Local Storage: The extension stores authentication tokens and user preferences locally on your device using Chrome's storage API.
• Anonymous Use: You can use the extension without signing in. In anonymous mode, no data leaves your device except the word lookup request, and no personal data is stored on our servers.
• Authentication: If you choose to sign in, the extension uses a secure PKCE-based flow and Firebase Authentication. An offscreen document is used to maintain your sign-in state — it handles authentication only and has no access to your browsing data.

6. Data Retention

Account data is kept as long as you maintain an account. Search history is stored until you delete your account or request erasure. Log data is kept for a limited period for security and troubleshooting.

7. Your Rights (under GDPR)

• Access the personal data we hold about you.
• Request correction or deletion of your data.
• Object to or restrict processing.
• Request a copy of your data (data portability).
• Withdraw consent for analytics cookies.
• Lodge a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens).

To exercise these rights, email us at info@wordholder.com.

8. Data Security

We use encryption and security measures to protect your data. However, no system is 100% secure, and we cannot guarantee absolute protection.

9. Changes to This Privacy Policy

We may update this Privacy Policy. Changes will be posted on this page, and the "Effective Date" will be updated.
