Privacy Policy

Last updated: 2/19/2026

Introduction

This Privacy Policy describes how 5Learn ("we", "our", or "the app") handles information when you use our language learning application. We are committed to protecting your privacy and being transparent about our practices.

Third-Party AI Processing

5Learn uses the OpenAI API to generate translations, explanations, and learning cards.

  • What data is transmitted: When you submit a word or phrase to create a card, we send to OpenAI: (a) the exact text you entered, and (b) the prompt templates from app settings (instructions you can view and edit in Settings). Together these form the full request for card generation.
  • What is not transmitted: No account credentials, payment data, or personal identifiers are sent.
  • Who receives it: OpenAI, Inc. receives and processes the submitted text through their API.
  • Purpose: To generate translation, context, examples, and card content for your learning.
  • Storage: The API key is stored locally on your device. 5Learn does not store user prompts on our servers.

OpenAI processes data according to their privacy policy and provides adequate data protection measures. For full details: OpenAI Privacy Policy

By using card generation features, you consent to this data processing.

Data We Collect and Use

Local Storage

All your learning data — word cards, lists, and settings — is stored locally on your device. We do not upload, sync, or store this data on our servers. Your cards, lists, model and prompt preferences, and learning progress remain on your device only.

What We Do Not Do

  • We do not require or create user accounts.
  • We do not collect or use analytics (e.g., Firebase, Amplitude).
  • We do not use cloud sync or store your data on external servers.
  • We do not sell, share, or rent your data to third parties.
  • We do not use advertising or tracking.

Your Rights

Because your data is stored locally on your device, you have full control over it. You can delete the app at any time to remove all stored data. If you have questions or concerns about your privacy, contact us at [email protected].

Changes

We may update this Privacy Policy from time to time. The "Last updated" date at the top reflects the most recent changes. Continued use of the app after changes constitutes acceptance of the updated policy.
