Kestrel Support
SRS vocabulary app for English → Spanish
What Kestrel is
Kestrel is a recognition-review vocabulary app: you see a word in your target language and recall what it means in English. A subscription unlocks the full English → Spanish Inventory. English → French is a starter-slice dogfood build only at v1 — there is no paid full-French path yet. Kestrel is not for learning Spanish from zero; it assumes you already have some exposure and want to strengthen recognition.
Kestrel is developed by James Ward.

Common questions
How do I restore my subscription?
In the app, open Settings → Restore purchases (signed in with the same Apple ID you used to subscribe). You can also tap Restore purchases on the paywall.
How do I cancel or change my plan?
Apple handles billing. Open Settings → Manage subscription in the app, or go to Apple ID → Subscriptions in iOS Settings.
Does Kestrel work offline?
Yes. Review sessions and your progress stay on your device. Subscription verification may need a network connection occasionally.
How do I delete my data?
Uninstall Kestrel from your device (and use iOS “Delete App Data” if offered). There is no account or server copy. See our Privacy Policy for details.
