FAQ
Do I need an account?
No account is required. Open the app and start learning.
Is Preplex good for exams (IELTS/TOEFL/SAT/GRE)?
Yes. Short, focused sessions help you build and retain vocabulary for test prep.
Why didn’t I see the tracking (ATT) prompt?
iOS shows it only once per install and only when eligible. You can reset permissions under Settings → Privacy & Security → Tracking.
Why don’t I see a consent form?
Consent forms (UMP) are region-based. If no form is required for your region, you won’t see one.
Do ads block the app?
No. Banner ads are lightweight. Interstitial and rewarded placements are rate-limited and optional.
Troubleshooting
Banner not showing
- Check internet connection and reopen the app.
- Some regions or debug settings may limit ad demand—this is normal.
App crashed or froze
- Relaunch the app once so the crash report uploads.
- Make sure you’re on the latest version from the App Store.
Reset tracking/consent
- ATT: Settings → Privacy & Security → Tracking
- Ad consent (EEA): Clear Safari history or reinstall the app to reset consent.
