We're here to help.

Open Gavia and tap Get Started. Sign in with Apple or Google, or enter your email address to receive a one-time verification code. No password is required. You will then complete a guided onboarding that captures your diagnosis, symptom baselines, current medications, and preferences.

Your health profile is built during onboarding. Gavia asks about your diagnosis type (Crohn's disease, ulcerative colitis, or IBD-unclassified), disease location, symptom baselines, current medications, and optional demographics. You can update any of this information later in Profile, then Health Profile.

Yes. Gavia is built offline-first. All tracking, check-ins, medication reminders, and data entry work without any internet connection. AI-powered features (GutGuide and your weekly health report) require a connection, but your tracking data is never lost if you go offline.

Not yet. An Android version is planned. Join our Android waitlist and we will notify you when it launches.

iPhone 8 or newer with iOS 16+.

Open the Track tab and select BM. Record consistency, urgency, the presence of blood, and whether it was a nighttime occurrence.

Open the Track tab and select Medications. You can quick-select from a library of common IBD medications (biologics, immunomodulators, corticosteroids, aminosalicylates) or add custom medications with dose, frequency, and reminder times. Medications are organized by three priority tiers: Critical, High, and Normal.

Open the Track tab and select Nutrition. Search the built-in IBD-relevant food database or add a custom item. Gavia tracks macronutrients (calories, protein, carbs, fat) and six critical micronutrients (Iron, B12, Vitamin D, Calcium, Zinc). After logging, you can record any post-meal symptoms to help Gavia identify trigger foods over time.

Start a flare from your Today dashboard or the Pain tab. While a flare is active, Gavia adapts: hydration targets increase by 50%, the Nutrition tab highlights safe foods and enables a low-residue filter, and a flare checklist helps you stay on top of hydration, rest, monitoring, trigger food avoidance, and medications. End the flare when you are ready, and it is recorded on your Health Timeline.

Guided check-ins take under two minutes each. The morning check-in covers sleep quality, current pain level, medication confirmation, and mood. The evening check-in covers bowel movement summary, fatigue, medication review, and mood. Check-ins appear as a card on your Today dashboard.

Yes. The Mind tab lets you track daily mood and stress levels. It also includes PHQ-9 (depression) and GAD-7 (anxiety) in the Mind section — a self-awareness screening tool, not a diagnosis. During setup, a brief PHQ-2 establishes your baseline. If screening scores indicate distress, Gavia detects your region and immediately displays your local crisis helpline — 988 in the US, Samaritans in the UK, Lifeline in Australia, and 16+ countries supported.

Gavia requires a Gavia Pro subscription. It includes 25 GutGuide AI conversations a day, weekly health reports, full symptom history, all pattern insights, and doctor report generation.

Go to Profile, then Subscription. Choose Monthly ($11.99/month), Quarterly ($24.99 every 3 months), or Annual ($89.99/year with a 7-day free trial). Payment is handled through your Apple ID.

Subscriptions are managed by Apple. Open Settings, tap your name at the top, tap Subscriptions, find Gavia, and tap Cancel Subscription. You will retain access until the end of your current billing period.

Go to Profile, then Subscription, then tap Restore Purchases. This connects to your Apple ID and restores any active subscription.

Yes. Your data is stored in an encrypted database on your device; the encryption key lives in the iOS Keychain and never leaves your device. Tracking data is encrypted in a local SQLite database. All data transmitted to cloud backup is encrypted in transit (TLS 1.2+) and at rest. Cloud storage uses Row Level Security — you can only access your own data.

Yes. Go to Profile, then Data and Privacy, then Export My Data. Your complete health history exports as a structured JSON file containing every record across all tracking categories. Available whether or not you are subscribed, under GDPR Article 20 data portability.

Scroll to the bottom of the Profile screen and tap Delete Account. You will complete a brief feedback survey, then all of your data will be permanently removed from the app and our servers. This action is irreversible.

Gavia shares limited data with three service providers, and nothing else. Anthropic (AI provider) receives your tracking summaries, your clinical context including medication names and doses, and the message you typed — with your name, email and other identifiers removed first. Your mood entries, screening answers, documents and care team are never sent. Sentry (crash reporting) receives crash data only, scrubbed of all health information. RevenueCat (subscriptions) receives purchase status only, no health data. The Gavia app is currently ad-free. See our Privacy Policy for full details.

Gavia stores all data locally first, so nothing is lost. If cloud sync is not working, check your internet connection and try closing and reopening the app. If the issue persists, contact support@gaviahealth.com.

Go to your iPhone Settings, then Privacy and Security, then Health, then Gavia, and make sure the relevant data categories are enabled. If you skipped HealthKit permissions during onboarding, you can enable them later in Profile, then Data and Privacy, then Apple Health.

GutGuide requires an internet connection and an active Gavia Pro subscription. Check both, then try again. If the issue continues, contact support@gaviahealth.com.

Go to Profile, then Preferences, then Appearance. Choose Light, Dark, or System (which follows your iPhone's setting).
