Mighty Nimble stores the minimum data needed to do its job. Here's what that is and why we need it.
Profile data
Age, gender, height, weight, fitness level, goals, health conditions, and your free-form notes
Why: So the AI can generate routines that fit you
Routine content and history
Every routine you've created, including the prompt you used and edits you made
Completion logs when you finish a workout
Why: So the AI gets better at tailoring routines over time (especially on Plus, which uses your history as context), and so you have your own workout record
Voice prompts (transient)
Audio is transcribed and then discarded. The transcribed text becomes part of your routine's prompt history; the audio itself is not kept.
Why: Transcription is part of how voice input works — it's not something we can do without.
Authentication
A user ID we get from Apple Sign-In
Optionally your name and email (you control what Apple shares)
Why: To identify your account across sessions
Device tokens
A push notification identifier tied to your iPhone
Why: So we can send you a push when your routine is ready
Usage analytics
Anonymized / pseudonymous product analytics (what screens you visit, which buttons you tap)
Not tied to your real identity
Why: To understand which features are used and where to improve
Subscription status
Whether you're Plus or Free, and when your subscription renews or ends
Why: To apply the right limits
