Privacy Policy

At PrettyPrint, privacy isn't a footnote.
It's the architecture.

Last updated: July 10, 2026

The short version

PrettyPrint runs entirely on your device. Text transformations are performed by Apple's on-device AI (Apple Intelligence) — your text is never sent to PrettyPrint, to a cloud AI provider, or to anyone else. There is no account, no sign-in, no analytics, and no PrettyPrint server processing your writing. We cannot see your text, so we cannot store it, sell it, or train on it.

1. What PrettyPrint does

PrettyPrint is an AI-powered keyboard for iOS that transforms text using Apple's on-device foundation models. When you tap an action (e.g., "Fix Grammar," "Translate to Portuguese"), the transformation happens locally on your iPhone's Neural Engine. The text you write, the instructions you create, and the results you produce stay on your device.

2. What we collect

Nothing. PrettyPrint has no account system, no analytics SDK, and no backend that receives your data. Specifically:

  • We do not receive, store, or log the text you type or transform.
  • We do not record what you type in other apps or track your keystrokes.
  • We do not collect usage analytics, device identifiers, or crash telemetry on our servers.
  • We do not require or offer an account — there is nothing to sign in to.
  • We do not sell, share, or monetize any personal data — we don't have any.
  • We do not use your data to train AI models — your text never reaches us.

Your custom actions, preferences, and the prompt library are stored locally in the app's own storage on your device and are removed when you delete the app.

3. Network connections the app makes

PrettyPrint works offline. The few network requests it can make are content downloads and sharing features — none of them carry your typed text:

Prompt catalog updates
The app may download an updated catalog of optional prompt ideas (a static file on our website). This is a one-way download; nothing about you or your writing is uploaded. Like any web request, our hosting provider (Firebase Hosting) may log standard request metadata such as IP address and timestamp.
Shared action links
If you choose to share one of your actions with a friend, the action's name and instruction text are encoded into the link itself and delivered by whatever app you share it through (e.g., WhatsApp, Messages). Only share actions you're comfortable sending. Opening a shared link may load a page on our website with the same standard web logging.
Apple App Store
Distributes the app and processes your one-time purchase. PrettyPrint never receives payment details. Apple's own privacy policy governs the App Store.
Apple Intelligence
Text transformations use the on-device model that ships with iOS. Processing happens on your iPhone; PrettyPrint does not send your text to Apple's servers. Apple's platform terms govern the on-device model.

4. Sensitive information

Because processing is on-device, using PrettyPrint with personal or sensitive text does not transmit it anywhere. Two common-sense notes: text you send after transforming goes wherever you send it (that's between you and the app you're typing in), and action links you share contain the action's instruction text by design.

5. How text processing works

  1. You tap an action in the PrettyPrint keyboard.
  2. The keyboard reads the text in the current field and runs Apple's on-device model with your action's instruction.
  3. The transformed text replaces (or previews over) the original — all on your iPhone.

No PrettyPrint server is involved at any step. Transforms work in Airplane Mode.

6. Data deletion

Everything PrettyPrint knows lives on your device. Deleting the app deletes your actions, preferences, and all locally stored data. There is no server-side account or copy to erase, which is the strongest form of the deletion rights granted under GDPR, CCPA, and LGPD. If you have any privacy question or request, contact us at privacy@prettyprint.ai.

7. Children's privacy

PrettyPrint is not directed at children under 13, and because it collects no personal information, it does not knowingly process any child's data.

8. Changes to this policy

We may update this privacy policy from time to time — for example, if we add optional online features. Material changes will be communicated through the app or on this page, and any feature that would send data off your device will be clearly disclosed and opt-in. The "Last updated" date at the top reflects the most recent revision.
