Privacy Policy for Prexy

Last updated: 29 August 2026

This policy covers the Prexy apps for macOS, iOS and iPadOS (“the app”), published by Michael Shear. It explains what the app stores, where it is stored, and who can reach it — which, in every case, is you.

What the app stores

Everything the app stores is content you created:

• The text of your notes.
• The metadata each note carries: its slug, its beat, its status, and created and modified timestamps.
• Files you attach to a note, and cached thumbnails of them.
• Links between your notes.
• A local version history of your own edits, so a note can be recovered and so a conflicting edit made on two devices can be resolved without losing either one.
• Your settings: text size, theme, your beat list, the default beat, window preferences, keyboard shortcuts, whether task syncing is on and which Reminders list it uses, and the reference to the folder you chose for the Markdown copy. These are stored in the app's own preferences, readable by this app alone.

That is the entirety of it. The app does not store or transmit:

• Your name, email address, or any account or login information — there is no account.
• Device identifiers, advertising identifiers, or IP addresses.
• Location data.
• Analytics, telemetry, usage statistics, or crash reports of any kind.
• Your contacts, photos, calendars, messages, browsing history, or any other data belonging to other apps.

Where it is stored

In up to three places, all of them yours:

1. On each device, inside the app's own private container.
2. In your private iCloud database, if you have iCloud enabled. This is Apple's CloudKit, running inside your Apple Account and billed against your iCloud storage. It is what keeps your Mac and your iPhone in step. The developer has no access to it, no credentials for it, and no way to read, copy or analyse its contents. Its handling by Apple is governed by Apple's privacy policy.
3. In the folder you choose on your Mac, as a plain-Markdown copy of every note — one .textbundle folder per note, containing the note as text.md plus any attachments. The app writes there only because you explicitly granted that folder, and it writes nothing outside it.

The macOS app also keeps its own periodic backup of the note store on your Mac. Backups never leave your machine.

Network access

The app makes no network requests of its own. There is no server to talk to. Syncing happens entirely through Apple's iCloud infrastructure, initiated by the operating system on your behalf.

One point of full disclosure: the macOS app declares the system's network-client entitlement. That is required because macOS's own Quick Look previewer for HTML files runs inside the app's process, and without the entitlement it crashes when previewing a purely local file you attached. It is not used by the app to contact anything, and the app contains no networking code.

Apple Reminders

If — and only if — you turn on task syncing, the app asks your permission to access Reminders, and then keeps checkbox lines in your notes in step with reminders in the list you chose. This happens entirely on your device through Apple's EventKit framework. Your reminders are read and written locally; nothing about them is transmitted anywhere by the app, and the developer never sees them. The app never sets or alters a reminder's due date. Denying or revoking the permission disables the feature and affects nothing else, and turning the feature off leaves any reminders you already have untouched.

Third parties

There are none. The app bundles no third-party analytics, advertising, attribution, crash-reporting or tracking libraries. No data about you or your notes is shared with any third party, because none is ever sent anywhere. Apple is not a third party in this sense — it is the platform your own iCloud account runs on, and it receives your notes only in your private database, at your instruction.

Tracking

The app does not track you, across apps or websites or at all, and contains no tracking domains. Nothing about your use of it is ever measured or reported.

Your control over your data

• Delete any note from within the app; the deletion syncs to your other devices.
• Turn off iCloud syncing for the app in your device's iCloud settings at any time. Your notes remain on the device.
• Open, copy, edit or delete the plain-Markdown copies in your notes folder with any tool you like — they are ordinary files, deliberately so, and they mean you are never locked in.
• Revoke Reminders access in System Settings (macOS) or Settings (iOS).
• Uninstall the app, which removes its local data from that device. Data held in your own iCloud account is removed through your Apple Account settings, in the same way as for any other app.

There is nothing to request from the developer, because there is nothing held by the developer.

Children's privacy

The app is not directed to children under 13, and does not knowingly collect personal information from anyone of any age — it collects none at all.

Changes to this policy

If the app's data handling ever changes, this page changes with it: the updated policy will be posted at this URL and the “last updated” date above revised.
