Frequently asked questions

What is arcoco?

arcoco is a vocabulary-building app for iPhone. It helps you practise sharper word choices through short rounds such as synonym matching, cloze prompts, scenario questions, pressure-test exercises, and jumble or spelling practice. It is built and maintained by Arcoco Ltd in the United Kingdom.

Do I need an account?

No. arcoco is designed to work without an arcoco account, public profile, or login. Your practice progress is stored on your iPhone. arcoco Plus purchases are handled through Apple and RevenueCat, not through an arcoco login account.

How do I get help with the app?

Email support@arcocoapp.com with a description of what happened. If you can include your iPhone model, iOS version, arcoco version, and the part of the app you were using, that helps us reproduce the issue quickly.

How do arcoco Plus subscriptions work?

arcoco Plus is purchased through Apple's in-app purchase system. You can upgrade from Settings > Upgrade to arcoco Plus or when you reach the free daily limit. Restore Purchases is available in Settings and on the paywall. Active subscribers can manage or cancel through Settings > Manage Subscription or through Apple App Store settings.

What should I do if my purchase did not unlock?

Use Restore Purchases first. If that does not fix it, email support@arcocoapp.com and include the Apple ID region, the approximate purchase time, and whether the purchase was monthly or yearly. Do not send payment card details.

How do Daily Reminders work?

Daily Reminders are optional. arcoco asks for notification permission only when you choose to enable reminders. You can turn reminders on or off in Settings > Daily Reminders, and you can also change notification permission in the iOS Settings app.

How do custom mascot photos work?

Custom mascot photos are optional and started from Settings > Session Mascot. You can take a photo or select one from your photo library, then adjust the cutout. The photo is processed and stored locally on your iPhone and is not uploaded to arcoco servers. Choosing a stock mascot clears the saved custom photo assets.

How do I report a bug or suggest a feature?

Send us a note at support@arcocoapp.com. Screenshots, the exercise type, and the word or prompt involved are especially useful when something looks wrong.

How is my data handled?

arcoco stores practice progress on your iPhone and does not require an account. Release builds may use Firebase for analytics, diagnostics, crash reporting, performance monitoring, and remote configuration. Apple and RevenueCat handle arcoco Plus purchase status and entitlements. See the Privacy Policy for the full details. For any privacy-specific question or request, email privacy@arcocoapp.com.

How do I delete local app data?

Deleting arcoco from your iPhone removes the app's local practice data, settings, reminder preferences, and custom mascot photos from that device. arcoco Plus subscriptions are managed separately through Apple.

Who operates arcoco?

arcoco is operated by Arcoco Ltd, a company registered in England and Wales (company number 10951526).
