What it does

Chronicle lets you record what affects how you feel, over time, and see how those things relate to each other:

• symptoms, mood and sleep;
• nutrition, exercise and medications;
• biometrics, lab results and cognitive tests;
• insights and periodic reports built from what you logged.

Privacy is the architecture, not a promise

No servers, no user accounts, no ads, no analytics, no trackers. Everything is stored locally on the device. If your operating system's backup is on, a copy also sits in your own cloud account — not ours, and we receive nothing from it.
