Privacy Policy

Last updated: May 19, 2025

Overview

Your privacy is important to us. Lexo is designed with privacy in mind: the App stores all data locally on your device using SQLite and does not transmit any personal information to external servers. We do not collect, store, or share your personal data.

Data We Do Not Collect

Lexo does not collect or transmit:

  • Your name, email address, or any other identifying information
  • The flashcard content or decks you create
  • Your review history or learning progress
  • Your device's location
  • Usage analytics or behavioral data
  • Crash reports or diagnostics

Data Stored Locally on Your Device

The App stores the following data exclusively on your device — it never leaves your device and is not accessible to us:

  • Flashcard decks and cards you create (front and back content)
  • SM-2 review data per card (ease factor, interval, repetition count, next due date)
  • App preferences and settings

This data is stored in a local SQLite database on your device. It is cleared if you uninstall the App or reset your device.

Notifications

Lexo may request permission to send local push notifications to remind you of daily review sessions. These notifications are scheduled locally on your device and do not involve any external server communication. You can disable notifications at any time in your device settings.

Third-Party Services

Lexo does not integrate any third-party analytics, advertising, or tracking SDKs. No data is shared with or sold to third parties.

Children's Privacy

Lexo does not knowingly collect personal information from children under the age of 13. Since no personal data is collected, the App is safe for use by all ages.

Data Security

Because all data remains on your device, security depends on your device's own security measures (screen lock, encryption, etc.). We encourage you to keep your device and operating system up to date.

Your Rights

Since Lexo does not collect any personal data, there is no data held by us to access, correct, or delete. All data stored by the App lives on your device and can be removed by uninstalling the App.

Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected by updating the "Last updated" date at the top of this page.
