1. Introduction

Welcome to Lessign.com (“we”, “our”, “us”). We are committed to privacy by design. The AI Detox mobile app processes data fully on-device and does not transmit app data to us. Our website is informational; we set no cookies and run no tracking.

This page provides general information and does not constitute legal advice.

3. Scope & Summary

  • App (AI Detox): On-device only. No server connection. No analytics. No tracking. No cookies. No data transmitted to us.
  • Website (lessign.com): Hosted by STRATO GmbH in Germany. No cookies. No tracking. Security-only server logs by the host.

4. App: Zero Remote Collection

AI Detox does not transmit personal data to us. The app operates fully offline.

  • No analytics, telemetry, crash reporting, or advertising SDKs
  • No accounts, logins, or authentication

5. App: Local Storage Only

AI Detox stores minimal app state locally via iOS UserDefaults / Android SharedPreferences, never transmitted.

  • App usage state (current app in use to trigger cognitive challenges)
  • Knowledge Points counts for completed challenges
  • Challenge completion timestamps and totals

Deleting the app removes this data from your device.

6. App: Network & Permissions

  • No network communication or cloud sync (no iCloud/Google Drive)
  • No third-party SDKs integrated
  • Minimal, optional usage access permissions to trigger challenges; processing remains on-device. If you deny permissions, related features may not work.

7. App: Legal Bases

We do not receive your app data. To the extent GDPR applies to on-device processing, the legal basis is Art. 6(1)(b) GDPR (performance under the EULA) and/or Art. 6(1)(f) (legitimate interests in providing core functionality).

8. Website Visits: Server Logs (Art. 6(1)(f))

Our host STRATO GmbH processes standard server logs for security and availability. We set no cookies and run no analytics.

  • Data: IP address, date/time, URL, referrer, user-agent, HTTP status, bytes sent
  • Purpose: operate, secure, and troubleshoot the site; detect abuse/attacks
  • Retention: IPs in logfiles stored by STRATO for up to 7 days; extended only to investigate incidents

  • Legal basis: Art. 6(1)(b) GDPR (pre-contractual/contract communication) or Art. 6(1)(f) GDPR (legitimate interests in communication)
  • Retention: Only as long as necessary to handle your request or as required by law
