Privacy Policy

Last updated: June 15, 2026

Musing (“the app,” “we,” “us”) is a note-taking app. This policy explains what information the app handles and why. The short version: your notes live on your device, the AI features send what they need to process to Anthropic, and we never sell your data or use it to train models.

Notes stay on your device

The notes you create — your text, transcripts, photos, and the context captured with them — are stored locally on your device. If you enable iCloud, Apple syncs that data across your own devices under your Apple account; we never receive a copy.

What the AI features process

Musing’s AI features (search, “ask your notes,” note enhancement, and hidden tagging) are powered by Anthropic’s Claude. To provide them, the relevant content is sent — over an encrypted connection, through our own secure relay — to Anthropic for processing:

• The text of the note or query involved in the request
• Photos you attach (so the AI can read and describe them)
• Lightweight context such as approximate location, time, and weather, used to make results more relevant

Anthropic processes this to return a result and does not use data submitted through the API to train its models. We do not store your note content on our own servers; our relay simply forwards requests and adds no logging of your content.

Location & weather

If you allow location access, Musing uses your location to tag where a note was made and to fetch local weather via Apple WeatherKit. You can turn any context signal off at any time in the app’s Settings.

Voice

Voice notes are transcribed on your device using Apple’s on-device speech recognition. The recorded audio is stored on your device with the note.

What we don’t do

• We do not track you across apps or websites.
• We do not show ads or use advertising identifiers.
• We do not sell or share your personal data.
• Your data is never used to train any AI model.

Subscriptions

Musing offers optional subscriptions. Purchases and renewals are handled by Apple through the App Store; we never see your payment details. You can manage or cancel a subscription in your Apple account settings.

Keeping & deleting your data

Because notes are stored on your device, you control them: delete a note in the app, clear all notes in Settings, or remove the app to delete its data from that device (iCloud-synced copies are removed per Apple’s sync).

Children

Musing is not directed to children under 13 and does not knowingly collect information from them.

Changes

We may update this policy as the app evolves. Material changes will be reflected here with a new “last updated” date.
