Effective Date: October 28, 2026 · Version 1.0 (Android). For the iPhone app, see the iOS policy.

      LexFlex does not collect, store, or transmit any personal data to Labham LLC. There are no user accounts, no analytics, and no advertising. All data stays on your device.
    

Data We Collect

None. LexFlex does not collect any personal information, usage data, device identifiers, or location data.

Data Stored on Your Device

LexFlex stores the following data locally on your device only, in the app's private storage on your phone:

Your game statistics (wins, streaks, scores), your custom "My Words" word lists, your challenge history, your display name, and, if you enter it, your phone number (it is only shown to you and is never put in a challenge link). This data never leaves your device and is not accessible to Labham LLC or any third party.

Challenges and Peer-to-Peer Sharing

When you create a challenge, it is encoded entirely on your device into a secure HTTPS link. This link contains only the puzzle word (obfuscated), your display name, your chosen category, and your target score. No phone numbers or email addresses are included.

Challenge links are shared directly with your recipient through WhatsApp, Messages, or any messaging app of your choice. Labham LLC does not operate any servers involved in transmitting challenges between players.

When a recipient plays your challenge and sends back a result, that result travels the same way — directly from their device to yours as a link. The result contains only their tries, score, time, and display name.

The intermediate redirect page (labham.com/lexflex-c.html and labham.com/lexflex-r.html) is a static HTML page hosted on labham.com. Your web host's standard server logs may record the IP address and timestamp of requests to this page, as is standard for any website visit. Labham LLC does not process or retain these logs beyond standard hosting.

Result Signing Key

To protect the integrity of challenge results, LexFlex generates a cryptographic secret key on first launch and keeps it in the app's private storage on your phone. This key is used to sign and verify results so that scores cannot be tampered with. It is never transmitted to Labham LLC or any third party.

Android Backup

If Android backup is turned on for your Google account, Android may include LexFlex's on-device data (listed above) in your own backup, so it can be restored on a new phone. That backup is made and stored by Google under your account and settings; Labham LLC cannot access it. Uninstalling the app or clearing its storage removes the data from your phone.

In-App Purchases

LexFlex Plus is a one-time in-app purchase processed entirely by Google Play. Labham LLC does not receive or store any payment information. Google's privacy policy governs that transaction.

Third-Party Services

LexFlex does not integrate any third-party analytics, advertising, crash reporting, or tracking SDKs. The only Google library in the app is Google Play Billing, used solely for the LexFlex Plus purchase.

Children's Privacy

LexFlex does not knowingly collect any data from anyone, including children under 13. There is nothing to collect.

Changes to This Policy

If this policy changes, the updated version will be posted at this URL with a revised effective date.
