Last updated: 2026-04-12
Greenwort is a language-learning app operated by Lemma.
This Privacy Policy explains, in plain language, what data we use, why we use it, and what choices you have.
Who This App Is For
Greenwort is currently prepared for a Europe-first launch. We aim to keep this policy understandable for users in the European Union, the European Economic Area, the United Kingdom, and Switzerland, while also using it as the public privacy notice for all users.

Depending on how you use the app, we may use the following categories of data:
- Account information, such as your sign-in method, user ID, and email address
- App settings, such as app language, learning preferences, and subscription state
- Content you provide, such as uploaded files, imported URLs, AI prompts, saved words, and feedback messages
- Usage and app activity data, such as screen views, important feature events, and reading-progress events
- Diagnostics data, such as crash reports, error logs, app version, platform, and basic device details
- Purchase-related data needed to verify Google Play subscriptions
We do not sell personal data.

- Create and secure your account

These providers process data on our behalf to deliver the service.
Data Retention
We keep data for as long as it is reasonably needed to operate the app, maintain user accounts, provide subscriptions, investigate abuse, comply with legal obligations, and resolve disputes.
Retention periods may differ depending on the type of data. For example, account records, subscription records, app content, and diagnostics may be kept for different periods based on operational and legal needs.
Your Choices And Rights
You can stop using the app at any time.
If you are in Europe, including the EU, EEA, UK, or Switzerland, you may have rights to request access to your personal data, correction of inaccurate data, deletion of data, or a copy of certain data, subject to applicable law.

Children
Greenwort is not intended for young children. The current Play listing target audience should remain aligned with the release plan and applicable platform requirements.
Security
We use reasonable technical and organizational measures to protect data in transit and at rest. No system can be guaranteed to be completely secure.
