Privacy policy

Your files are yours.
Full stop.

Crease is a native Mac app that does all of its work on your device. We don't have your files, we don't want your files, and this page explains — in plain English — exactly what that means.

Effective   April 22, 2026 Version   1.0 Applies to   Crease 1.x for macOS
The short version Verified
  • Your PDFs never leave your Mac. Every operation runs on-device, in the app's sandbox.
  • We don't have an account system. There's nothing to sign up for, so there's nothing to leak.
  • No telemetry, no analytics, no ads. Crease doesn't phone home and has no third-party tracking SDKs.
  • Only Apple sees the purchase. The Mac App Store handles billing; we get a sales report, not your identity.

01Who we are

Crease is developed by Last Splash Consulting Oy, a studio based in Finland. We publish apps through the Mac App Store. This policy covers the Crease app and the site you're currently on.

02What happens to your files

When you open a PDF or an image in Crease, the app reads it from disk using the standard macOS file picker or drag-and-drop. All processing — merging, splitting, reordering, rotating, compressing, converting — happens in the Crease process on your Mac, using Apple's PDFKit and Core Graphics frameworks.

There is no server involved. The output is written to a destination folder you explicitly choose. Crease doesn't keep a copy, and it doesn't keep a log of which files you opened.

Technical detail Crease runs inside the macOS App Sandbox with no network entitlements. The sandbox profile grants the app temporary, user-granted access to the specific files and folders you hand it — nothing more.

03What we do & don't collect

Apple requires every app on the App Store to publish a privacy "nutrition label." Here is ours, expanded.

We do not collect

  • Contents of any PDF, image, or other file you open in Crease.
  • File names, sizes, page counts, or any metadata derived from your documents.
  • Your name, email, postal address, or phone number.
  • Device identifiers such as IDFA, IDFV, MAC address, or serial number.
  • Precise or coarse location data.
  • Analytics events, session recordings, crash stack traces, or usage metrics.
  • Cookies or similar tracking technologies (the app has no web views, and this site sets none).

We do collect (only if you email us)

  • The email address and message body of support or feedback emails you send to us.

04Network activity

The Crease macOS app makes zero outbound network connections as part of normal operation. The app's sandbox has the com.apple.security.network.client entitlement disabled, which means the system will block any attempt to open a socket.

The two network-adjacent behaviors you may notice are both handled by macOS itself, not by us:

  • Mac App Store receipt validation. macOS verifies your purchase receipt with Apple when the app launches. This happens at the OS level and doesn't involve our servers.
  • Software updates. App updates are delivered through the Mac App Store. Your update preferences are controlled in the App Store app, not in Crease.

Our website (creasepdf.com) uses no third-party analytics, no advertising pixels, and no cookies.

05Payments

Crease is sold exclusively through the Mac App Store. When you purchase, Apple handles the transaction entirely. We never see your credit card, Apple ID email, name, or billing address.

Apple provides us with aggregated sales and refund reports — for example, "17 copies sold in Germany last week." These reports are used for bookkeeping and tax purposes only and contain no information that could identify an individual buyer. Apple's own privacy policy governs the transaction itself.

06Support emails

If you email or , your message — including your email address and anything you attach — arrives in an email inbox we operate. We keep those threads for as long as the conversation is active, plus up to 12 months afterward so we can recognize a follow-up.

Please don't attach sensitive documents to a bug report. If we need to reproduce an issue and you offer to send a sample PDF, we'll ask you first, and we delete it as soon as the bug is fixed.

07Your rights (GDPR & CCPA)

Because Crease doesn't hold any data about you beyond support emails you've chosen to send, most of the traditional data-subject rights are quick to exercise. If you'd like us to:

  • Tell you what we have — usually just a support thread, if any.
  • Delete it — including any attached files and our side of the conversation.
  • Export it — we'll forward you the thread.
  • Stop using it— easy; we only use it to answer your question in the first place.

Email from the address you originally wrote from and we'll respond within 30 days. California residents have the same rights under the CCPA; we don't sell or share personal information, and we never have.

08Children

Crease is a general-audience productivity app and is not directed at children under 13. We don't knowingly collect personal information from children. Since the app collects no personal information from anyone, this mostly takes care of itself — but if you're a parent and believe your child has emailed us, write to and we'll delete the thread.

09Changes to this policy

If we change how Crease handles data, we will update this page and bump the version number at the top. Material changes — anything that alters what we collect or how we use it — will also be announced as in-app release notes the next time you update, so you have a chance to read them before continuing.
