Where is my data stored?

Your signal logs, preferences, and Meridian's analysis stay on your device. There is no Meridian account or cloud sync. RevenueCat receives anonymous purchase history for Meridian Pro validation, entitlement functionality, and aggregate purchase analytics; it does not receive your logs or analysis, link the purchase data to your identity, or use it for tracking.

How do I export my data?

With Meridian Pro, Settings โ†’ Export data (JSON) creates a JSON file and opens the system share sheet. You decide where to save or send that copy. Meridian does not currently import or restore an exported file.

What can I track?

Core signals are sleep, energy, and mood. You can also enable focus, stress, headaches, digestion, and exercise. Meridian does not include custom notes.

How do the associations and next-day estimates work?

Meridian compares the signals you log and surfaces statistical associations on your device. An association does not show that one signal caused another. Meridian Pro can also show next-day estimates after you have logged enough data and an estimate passes the app's validation checks.

Does Meridian provide medical guidance?

No. Meridian is a personal tracking tool. It does not diagnose a condition, recommend treatment, or provide medical guidance.

What's in Meridian Pro?

Meridian Pro is a one-time unlock, not a subscription. It includes the full signal network, validated next-day estimates when enough data is available, 60- and 90-calendar-day trend ranges, and JSON export. Logging and the full calendar history remain available without Pro.

Still stuck, or found a bug?

Email us. The fastest way is the in-app Settings โ†’ Contact Support, which opens an email draft with your app version prefilled. It does not attach your logs. Or write directly to support@studioam.art.
