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. You can complete setup and play without signing in. Your practice progress is stored on your iPhone. In versions with progress saving, you can optionally connect Apple or Google from Settings > Progress to save and restore your learning progress. arcoco Plus purchases are handled separately through Apple and RevenueCat.

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 purchases work?

arcoco Plus unlocks unlimited games and the Streak Shield, which provides extra streak freezes for missed days. Purchases use Apple's in-app purchase system. Open Settings > Upgrade to arcoco Plus or reach the free daily limit to see the available plans and current prices. Monthly and annual plans are subscriptions that renew automatically unless cancelled. Where offered, Lifetime is a one-time purchase and does not renew. Restore Purchases is available in Settings and on the purchase screen. Active subscribers can manage or cancel through Settings > Manage Subscription or through Apple App Store settings. Buying Lifetime does not automatically cancel an existing subscription; manage that subscription separately through Apple.

What should I do if my purchase did not unlock?

Use Restore Purchases first, with the same Apple Account used for the purchase. If that does not fix it, email support@arcocoapp.com and include the Apple Account region, the approximate purchase time, and whether the purchase was monthly, annual, or Lifetime. Do not send payment card details or account passwords.

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. If you choose Apple or Google progress saving, Firebase handles the optional account and cloud-saved learning progress. Release builds may also use Firebase for analytics, diagnostics, crash reporting, and remote configuration. Apple and RevenueCat handle arcoco Plus purchase status and entitlements. Where supported, Meta advertising measurement is optional and requires your tracking permission. See the Privacy Policy for the full details. For any privacy-specific question or request, email privacy@arcocoapp.com.

How do I delete my data?

Deleting arcoco from your iPhone removes its local practice data, settings, reminder preferences, and custom mascot photos from that device. If you connected Apple or Google for progress saving, delete your account and cloud-saved progress from Settings > Progress before removing the app, or contact privacy@arcocoapp.com for help. Signing out or uninstalling alone does not delete cloud-saved progress. Deleting progress does not cancel an arcoco Plus subscription; subscriptions are managed separately through Apple.
