Email support →Last updated: August 25, 2026. This policy applies to the Paper Scan iOS application published by Mark Utility Labs.
Short version: Scanning and text recognition run entirely on your iPhone, and your scans, the recognised text and the PDFs you export never leave your device — there is no account and no server holding them. What does leave the app is anonymous and technical: a crash report when the app crashes, and a count of how the unlock screen is used. No ads, no advertising identifiers, no tracking you across other apps or websites, and no sale of your data, ever.
Paper Scan creates and stores the documents you scan or import: the page images, thumbnails, document titles, and any text recognized from a scan. This data is created and used entirely on your device.
Scanned pages are stored as image files in the app's private storage on your iPhone. Document metadata (titles, page order, recognized text) is stored locally using the device's standard app storage. Deleting a document in the app, or deleting the app itself, removes this data from your device.
Paper Scan uses Firebase Crashlytics, a service run by Google, to report crashes automatically so bugs get found and fixed. When the app crashes, a report goes to Google containing the device model, the iOS and app version, the technical details of the crash, and a random identifier Firebase generates for your installation of the app. That identifier is not your name, your email, or your Apple ID; delete and reinstall the app and it changes. A crash report never contains your scans, the text recognised from them, or the PDFs you export.
When Paper Scan shows its unlock screen, it counts a short list of events through Firebase Analytics, also from Google: that the screen was shown (and which of its two asks it was), that the free week offered there was taken, which layout was shown, and that an unlock completed. It also counts that the one-time offer sheet (the one that shows the other apps) was shown and what was tapped on it, and that the app asked whether you were enjoying it, with which of the two buttons you chose. These events carry no personal content — none of your scans, the text recognised from them, or the PDFs you export, no name, no contact details. Paper Scan never attaches your identity to them; Firebase records them against the same kind of per-install identifier described above. They exist so we can tell whether the unlock screen works, and for nothing else.
Apple handles the transaction itself. Mark Utility Labs never sees or stores your card details, billing address, or Apple ID password.
Your unlock is kept on your device, in the iOS Keychain. If you unlock the whole collection of Mark Utility Labs apps at once, that record is also kept in your own iCloud, using Apple's CloudKit, so it follows your Apple Account to a new device. It is stored in your private iCloud database, not somewhere we can browse. Paper Scan does not ask you to sign in to anything, and nothing about your purchase is sent to Google.
It's worth being explicit about the absences:
Google (Firebase) receives crash reports and the anonymous usage counts. Apple handles the transaction, and keeps the all-apps unlock record in your own private iCloud database. There are no other recipients.
Paper Scan requests the following permissions, each used only for the stated purpose:
Paper Scan is not directed at children under 13 and does not knowingly collect personal information from children. It never asks anyone, of any age, for a name, an email address, or any other identifying detail.
If this policy changes, we'll update the "Last updated" date above. Continued use of the app after a change means you accept the updated policy.

No company, no investors, no exit plan — just a retired dev, AI, and the growing conviction that this stuff should already cost almost nothing. I'm releasing a new app every week when the waves are bad and I'm not surfing.
Focus Hour
A to-do list, a day planner and a timer, because I kept losing track of all three.
Gym Log
Remembers what you lifted last Tuesday, so you don't have to.
Copy History
Your clipboard, but it remembers more than the last thing you copied.
Quiet Room
Rain, waves and a box fan. Layer them until you stop thinking.
SleepTracker
Tracks your sleep from your wrist or your pillow. No account, no nightly score to chase.
ZoneTime
Stops you cheerfully texting people at 4am their time.
Water Sort
Pour colors between bottles until they match. I lost a weekend to this one.
Cubby
A baby tracker built for 3am: dark, one-handed, no cheerful pastels.
Becoming
Affirmations over your own photos, read in your own voice.
