Frequently Asked Questions

How do I cancel my subscription?

Go to Apple ID > Subscriptions > OtoTheory and cancel from there. Your subscription will remain active until the end of the current billing period.

How do I delete my account?

In the app, go to Settings > Delete Account. Your account and all cloud data will be permanently deleted within 30 days.

How long is my data retained?

Sketches are kept until you delete your account. Usage logs and diagnostic data are kept for 90 days and then deleted or anonymized.

What is the difference between Shaped and Sounding?

Sounding shows the actual pitches you hear. Shaped shows the chord shapes you play with a capo. For example, with Capo 3, an Am shape sounds as Cm.

Can I export my progressions?

Yes! You can export as PNG images. Pro users can also export MIDI files with chord symbols, markers, and guide tones.

What does the 7-day free trial include?

The free trial gives you full access to all Pro features: unlimited cloud saves, MIDI export, and section editing. You can cancel anytime during the trial period.

How is key detection performed?

Our algorithm analyzes the pitch class profile (PCP) of your recording and compares it against major and minor key templates using correlation scoring.

Why use a capo?

A capo helps you: adjust vocal range, use more open strings for richer sound, and make chord shapes easier to play. Keys like C, G, D, A, and E are guitar-friendly.

Can I use OtoTheory offline?

Yes! Core features work offline. Cloud sync and account features require an internet connection.
