Support

Last updated: 28 July 2026

Got a question, found a bug, or want a feature? We're a small team and we read every message. The fastest way to reach us is email: support@vocagrow.com. We usually reply within one business day.

1. Common questions

How do I unlock the AI tutor?

The AI tutor is included with the Pro subscription — no API keys, no external accounts, no setup. Subscribe (3-day free trial), open the AI tab, accept the one-time data-sharing consent, and chat. Advanced users who prefer their own Google Gemini API key can still add one in Settings → AI tutor — that's entirely optional.

Do I need an account?

No — every learning feature works without one, entirely on your device. A free account (email, or Sign in with Google / Apple) is only for online play: it keeps your name and rating on the global duel leaderboard and lets you sign in on a new phone. You can also play online as an anonymous guest. To delete an account, email us from the account's address.

I don't see the prices I expected on the paywall

VocaGrow shows live prices straight from the App Store or Google Play, so they're shown in your local currency at the store's exchange rate. If you see fallback prices (in USD) it means the store couldn't be reached — usually a temporary network issue. Close and reopen the app.

My subscription isn't unlocking Pro

Open the app → Profile → Restore purchases. This re-queries the store for any subscription tied to the account you used. If that doesn't work, double-check you're signed into the App Store or Google Play with the account that made the purchase, then try again. Still no luck? Email us with the receipt and we'll fix it on our side.

How do I cancel my subscription?

Subscriptions are managed by the store you bought from. Open the app → Profile → Manage subscription to jump directly to the store's cancellation flow. You can also cancel from the App Store or Google Play account settings. Pro perks stay active until the end of your current billing period.

I want a refund

Refunds are handled by the store, not by us:

App Store: reportaproblem.apple.com — within 14 days of purchase.
Google Play: play.google.com/store/account/orderhistory — within 48 hours, or contact Google for older orders.

If the store declines and you have a clear case, email us and we'll advocate for you with them.

I'm on an older Android / iOS phone — will the app work?

VocaGrow needs Android 6.0 (API 23) or iOS 15.5 and newer. Older devices aren't supported.

Can I use the app offline?

Yes. Vocabulary, flashcards, games, grammar lessons, pronunciation and reading guides all work fully offline. Only the AI tutor, online duels, the leaderboard and ads need the internet.

2a. Delete my account

If you created a VocaGrow account (email, or Sign in with Google / Apple), you can delete it and all server-side data directly in the app:

Open Settings → Account.
Tap Delete account and confirm.

This immediately and permanently removes your account record, email, display name, duel rating, match history and cloud backup. Learning progress stored locally on your device is not affected (remove it via Settings → Delete my data or by uninstalling). If you can't access the app, email support@vocagrow.com from the account's address and we'll delete it within 30 days.

2. Delete my data

You can delete everything VocaGrow has on your device any time via Settings → Delete my data. To also delete your account records (email, display name, rating) or pseudonymous analytics that have already left your device, email support@vocagrow.com with your request — full details are in our privacy policy.

3. Report a bug

Email support@vocagrow.com with:

What you did (the screen / action).
What you expected.
What happened instead.
Your device model and OS version (helps a lot).
A screenshot or screen recording if possible.

4. Suggest a feature

Same address — support@vocagrow.com. We keep a roadmap and read every suggestion. If we ship your idea we'll let you know.

5. App Store / Google Play reviewer access

App Store and Play Store review teams: the AI tutor unlocks with a Pro purchase, which can be made in the sandbox environment at no cost (Profile → Pro → Monthly) — no API key or external account is needed. If anything is missing, email support@vocagrow.com and we'll respond within hours.
