Evo — Privacy Policy

Last updated: May 2026

Overview

Evo is built on a simple principle: your data is yours. We collect behavioral signals to generate your daily scores — and nothing else. We do not sell your data, share it with advertisers, or use third-party analytics SDKs that send your behavior to outside networks.

What We Collect

To generate your daily report, Evo accesses the following data from your device:

• Apple Health — sleep, heart rate variability, resting heart rate, steps, active calories, and workouts
• Screen Time — app usage duration, pickup count, notification count, and session patterns
• Location (optional) — coarse location patterns (outdoor time, location variety). Exact GPS coordinates are never stored.
• Calendar (optional) — meeting density and scheduling patterns. Event titles are processed on your device only; they are never sent to our servers.
• Spotify (optional) — listening patterns used as a mood proxy signal, accessed via OAuth
• Account information — email address used for authentication via Sign in with Apple or Google

How We Use Your Data

Your data is used solely to:

• Generate your daily behavioral scores
• Personalize scoring based on your onboarding responses
• Improve the accuracy of Evo's scoring models over time
