Quick answers
- I bought Premium but it's not showing up
- Open Settings in the app and tap Restore Purchase. Premium is tied to your App Store or Google Play account, so make sure you're signed in with the same account you bought it on.
- I want a refund
- Refunds are handled by the store, not by us. On iOS use reportaproblem.apple.com; on Android use the Google Play order history. We can't process refunds directly, but tell us what went wrong and we'll try to fix it.
- Ask AI isn't working
- Ask AI needs your own API key from OpenAI, Anthropic or Google, entered in Settings, plus an internet connection. If the key is valid and it still fails, check that the key has credit or quota remaining on the provider's dashboard.
- Currency rates look out of date
- Rates are cached so conversions keep working offline. Open the currency converter while connected and it will refresh.
- Delete my data / remove me from the waitlist
- App data lives on your device — uninstalling deletes it. For waitlist or support records held by us, send a message below and we'll delete them.
