Frequently asked questions

How does the spaced-repetition system work?

Each word you study is scheduled for review based on how confident you were when you last answered. Words you find easy come back less often; words you struggle with come back sooner. This optimizes the time you spend studying.

Does my progress sync between devices?

Yes — if iCloud is enabled on your devices and you're signed in with the same Apple ID, your progress, decks, and settings sync automatically through your private iCloud account. The app never sees your data on a server.

How do I cancel my PRO subscription?

Subscriptions are managed by Apple. Open the Settings app on your iPhone or iPad, tap your name at the top, then tap Subscriptions. Find LEX Word Practice and tap Cancel Subscription. Cancellations take effect at the end of the current billing period.

Can I restore a purchase on a new device?

Yes. Open the app, go to Settings, and tap Restore Purchases. Make sure you're signed into the same Apple ID you used to buy the subscription.

How do I delete my data?

LEX Word Practice doesn't keep your data on any servers — everything is stored locally on your device and (if enabled) in your private iCloud. To delete it: uninstall the app, then go to Settings → [Your Name] → iCloud → Manage Account Storage and remove LEX Word Practice's data.

I have a feature suggestion. Where do I send it?

Email lexwordpractice@gmail.com — every message gets read.
