Common questions

My blood panel did not parse correctly

Delta's parser validates every unit against an allowlist. If a marker was not recognised, it is because the unit label on your report does not match a known form, or the marker name could not be matched. Try a cleaner photograph with good lighting and flat paper. If the issue persists, email us with a description of which markers were missed (not the values, just the names and units) and we can check whether the form is in the parser.

My Adaptive Age did not compute

The Adaptive Age requires all nine blood markers plus your chronological age from your profile. If any one of them is missing, the app tells you which one and refuses to score. Check that your date of birth is set in the Me tab and that the report includes all nine required markers. The app shows which markers are present and which are absent after a parse attempt.

Apple Health data is not showing

Open Settings > Privacy & Security > Health > Delta on your iPhone and confirm that the required data types are set to read access. If you changed permissions recently, restart the app. Some data types - such as HRV - require a compatible Apple Watch to populate.

Withings is not connecting

Withings connection uses OAuth. If the connection fails, try disconnecting and reconnecting from the Me tab. Make sure you are authorising with the correct Withings account. Withings sync requires a network connection and may take a moment to retrieve readings.

ASK is not responding

ASK requires a configured backend proxy. In builds that do not include a proxy configuration, ASK is inactive and shows a clear message explaining this. If you have a configured build and ASK is not responding, check your network connection. If the issue continues, email us.

I want to delete my data

Your health data is stored locally on your device. To delete it, go to Settings > General > iPhone Storage > Delta and tap "Delete App", or use the delete option within the app's Me tab. Because data is local only, deletion is immediate and irreversible. Backend processing (blood report analysis, ASK) is stateless - no server copy exists to delete.

I found a bug or security issue

Please email info@deltahealth.fit. For security issues, mark the subject line "Security" and we will respond within 48 hours.
