Frequently Asked Questions

Where is my data stored?

All your health data is stored locally on your device. Nothing is sent to any server or third party.

How do I back up my data?

Go to Settings and tap "Export Backup." You'll create a password-protected encrypted file (.vitallog) that you can save anywhere — Files, iCloud Drive, email, etc.

How do I restore from a backup?

Go to Settings and tap "Import Backup." Select your .vitallog file and enter the password you used when creating it. Existing data won't be duplicated.

I forgot my backup password. Can you recover it?

No. Backups are encrypted with AES-256 using your password. We never have access to your password or your data. Without the correct password, the file cannot be decrypted.

What are the drug interaction warnings?

Vitallog checks your active medications against a local database of known interactions. These are informational only — always consult your healthcare provider about drug interactions.

How does the health summary work?

On supported devices, Vitallog uses Apple's on-device AI to generate a summary of your health data. All processing happens on your device. On other devices, a template-based summary is generated instead.

Can I track vitals not listed in the app?

Yes. Go to the Vitals tab, tap the add button, and choose "Create Custom Vital" to define your own vital with custom fields, units, and ranges.

Does Vitallog work without an internet connection?

Yes. Vitallog works entirely offline. No internet connection is needed for any feature.
