Keepnook — Privacy Policy

Last updated: 15 September 2026

Keepnook is a notebook app. Your notebooks are stored on the device you make them on. There is no account, no sign-in, and no Keepnook server holding your work.

Two things are ever sent from your device: a report when the app crashes, if you let it, and — on iPhone and iPad — the check that says whether you have bought a subscription. Neither carries anything you have written or made. That is the whole of it. The rest of this page is the detail.

What Keepnook collects

Crash diagnostics, and — if you buy a subscription — whether you have one. Nothing else.

Crash reports. Keepnook stores your notebooks on your device and has no account and no server. The one exception is crash reporting. If the app hits an error, and you have not turned crash reports off in Profile → Where your data lives, Keepnook sends a diagnostic report to Sentry, our error-tracking provider. A report contains the error and where in Keepnook's own code it happened, which build of the app you are on, your platform and operating system version, which browser and version if you are using one, the size of the app window, and a short trail of what the app had been doing — the last few screens you opened, by name, and events like starting up or saving, recorded as names and numbers and never as anything you wrote. If Keepnook stops abruptly rather than showing an error — a fault in the drawing engine or in the system underneath it — the report is written by Sentry's own crash handler rather than by Keepnook, and that kind of report also includes your device's model (for example "iPad Pro 11-inch") and how much memory and storage it had free. It does not contain anything you write or make, your photographs, any copy of what Keepnook has stored, or your name, email, location, device name or IP address — reports are not linked to your identity and are never used for tracking or advertising. You can turn crash reports off at any time; nothing further is sent, and nothing further is even recorded.

Crash reports are on by default. To turn them off: open Keepnook, tap the profile icon at the top of your shelf, and open Where your data lives. The switch is under Crash reports, and the same screen lists in full what a report does and does not contain. Nothing is sent while it is off.

Whether you have a subscription. Keepnook Plus is bought inside the app through Apple's App Store. Apple takes the payment; Keepnook never sees a card number, a billing address or your Apple Account, and there is nothing in the app that could store one. To know whether a subscription is running — so that the things it opens are open — Keepnook asks RevenueCat, the service that checks App Store receipts for us. That check is the second thing that leaves your device on iPhone and iPad, and it carries an anonymous identifier RevenueCat generates for the installation, your platform and app version, and the receipt Apple issued. It carries nothing you have written or made, no photographs, no name, no email address, and nothing that says who you are. If you never open the subscription screen and never buy anything, the check still runs at startup and still says the same thing about you: nothing.

What Keepnook does not collect

• No accounts and no sign-in. There is nothing to register for, and no password, email address or profile is ever asked for or stored.
• Nothing you write or make. Notebook titles, page text, drawings, stickers and layouts stay on your device.
• No photographs. Not the images, not their file names, not where they came from.
• No analytics. There is no analytics product in Keepnook, and no record is kept of what you tap, open or spend time on.
• No advertising, and no tracking. Keepnook shows no ads, contains no advertising or tracking software, shares nothing with data brokers, and joins nothing with data from anywhere else. Because of that, Keepnook never asks for permission to track you.
• No location, contacts, calendar, microphone or health data. Keepnook does not ask for any of these and cannot read them.
• No device or advertising identifiers, and no record of your IP address. Reports Keepnook builds itself are sent with the IP field explicitly emptied, and Sentry is configured not to store IP addresses for the reports its own crash handler builds. A device model is shared by millions of devices and does not identify you; your device's name is never sent. The one identifier that exists anywhere in Keepnook is the random one RevenueCat generates for the installation so that a subscription can be recognised as the same one tomorrow. It is not your device's identifier and not an advertising one, it is not joined to anything, and deleting the app is the end of it. As with any request over the internet, whoever answers one can see the IP address it came from as part of answering it.

Your notebooks

Everything you make — notebooks, pages, drawings, folders and settings — is saved in Keepnook's own storage on the device you made it on. It is not uploaded, there is no copy on a server, and nobody else can read it, including us. Keepnook has no sync: two devices running Keepnook know nothing about each other.

On iPhone and iPad, your notebook data is included in the device's own iCloud backup, if you have iCloud backup switched on. That is Apple's backup of your whole device — not Keepnook sync, and not something Keepnook can read. It is governed by Apple's privacy policy and controlled in iOS Settings.

The photographs you add are in that backup too: Keepnook keeps its copy of each one in the app's own documents folder, which Apple includes in the device backup alongside your notebooks.

Photographs and the camera

Keepnook does not ask for access to your photo library, and cannot read it. When you add a photo, your device shows you its own picker and hands Keepnook only the image you chose — the rest of your library is never visible to it, and there is no permission to grant or take back.

The camera is the one thing Keepnook asks for, so you can take a photo straight onto a page. It is optional: Keepnook works without it, and you can change your mind in your device's Settings at any time.

When you add a photo, Keepnook makes its own smaller copy of it in its storage on the device. Your original photo is not moved, changed or deleted. The copy is never uploaded, and the fact that you added it is not recorded anywhere off the device.

When you save a page of your notebook as a picture, Keepnook asks to add that picture to your photo library. That permission is add-only: it lets Keepnook put a picture in, and it does not let Keepnook read, change or delete anything that is already there. It is asked for at the moment you save, you can decline, and if you do, the page is not saved and Keepnook offers to share it instead. You can change your mind in your device's Settings at any time.

Nothing else Keepnook does touches your photo library.

Backups you make yourself

Because there is no server, the only backup Keepnook can give you is a file you write yourself: Where your data lives → Export a backup. It contains everything on the device, photographs included, and you decide where it goes. Once it leaves Keepnook it is an ordinary file — anyone who can read it can read your notebooks, so keep it somewhere you are happy with. Importing a file back adds to what is already on the device; if something in the file is already here and the file's copy is newer, Keepnook asks you what to do before it touches anything.

What Keepnook connects to

A crash report and the subscription check are the only things Keepnook sends anywhere. There is no account to check and no sync. Everything else described in this section is Keepnook fetching a file — asking for something public, never handing over anything of yours.

Keepnook fetches from one Keepnook address and nowhere else: the list of what is available, the details of a pack of artwork or of a notebook design, the artwork itself, a picture of a design's cover, and — only if you choose to start a notebook from a design — that design's own document, which can be tens of megabytes. Each of these is a request for a public file and nothing more. It carries no account, no identifier, and nothing from your notebooks; nothing records what you have made, or which design you looked at. As with any web page, whoever serves the file can see your device's IP address as part of serving it.

What Keepnook downloads stays on the device. Artwork and cover pictures are kept in a temporary store your device is free to empty whenever it needs the room, and which is deliberately left out of your device's backup, because Keepnook can simply fetch them again. A design's document is different: it becomes part of the notebook you made from it, and is kept alongside that notebook like anything else you put in one.

Apart from whoever serves those files, Sentry and RevenueCat are the only third parties Keepnook contacts, and each receives only what is described under What Keepnook collects. Apple is the third: it takes the payment for a subscription and issues the receipt, under its own privacy policy rather than this one.

Removing your data

Delete Keepnook from your device. That removes the app's storage with it: every notebook, page, drawing, photo copy and setting. There is nothing left on a server to delete, because there was never anything on one.

Export a backup first if you want to keep any of it. Deleting the app is final, and Keepnook cannot recover it for you.

Two things to know:

• If iCloud device backup is switched on, Apple may still hold a backup of your device that contains Keepnook's data until that backup is replaced or deleted. That is managed in iOS Settings, not in Keepnook.
• Any backup file you exported yourself stays wherever you put it.

Crash reports already sent cannot be withdrawn, because they carry nothing that identifies you or your device — there is no way to find yours among them. Turn the switch off and no more are sent.

Children

Keepnook collects nothing about anyone, of any age. There is no account, no sign-up, no age gate, no advertising, no tracking, and no way for one user of Keepnook to see or contact another. A crash report describes a fault in the software and carries nothing about the person using it.

Changes to this policy

If what Keepnook does with data changes, this page changes with it, and the date at the top changes. Keepnook's app-store privacy disclosure is kept in step with this page.
