Nothing is sent until I confirm? Correct. Taking or choosing a photo never uploads it; only Use this does, and only with Google sharing turned on.
How do I manage my subscription? In the app under Settings → Subscription, or in your Apple Account’s Subscriptions settings. Restore purchases from the same place.
How do I delete my data? Delete looks in History, or delete the app. Our service keeps no images, messages or accounts; see the privacy policy for the anonymous records it does keep and how to request their removal.
Is this veterinary advice? No. Dear Dog describes visible body language with uncertainty and suggests simple, safe responses. For health or behaviour concerns, consult a veterinarian or a qualified behaviourist.
