Effective Date: March 15, 2026

Last Updated: March 15, 2026

Knut: Book Scanner & PDF ("the App") is developed and maintained by Jussi ("we," "us," or "our"). This privacy policy explains how the App handles your information.

Our Core Commitment

Knut: Book Scanner & PDF does not collect, store, or transmit any personal data. The App operates entirely on your device. There are no servers, no accounts, no analytics, and no tracking of any kind inside the App. (The knut.fi website is a separate product and is covered in the "Cookies on knut.fi" section below.)

1. Information We Collect

None. Knut: Book Scanner & PDF does not collect any personal information, usage data, or analytics.

Specifically, the App:

Does not require an account or sign-in
Does not collect names, email addresses, or other personal identifiers
Does not track usage patterns or behavior
Does not use analytics frameworks (no Google Analytics, no Firebase, no third-party SDKs)
Does not use advertising identifiers
Does not collect crash reports or diagnostics

2. Camera Access

The App requests access to your device's camera solely to capture images of book pages for scanning. Camera access is used exclusively for this purpose.

Camera data is processed entirely on your device
Captured images are never uploaded, transmitted, or shared with any server
No facial recognition, object tracking, or image analysis beyond local page processing is performed
You can revoke camera access at any time through iOS Settings

3. Data Storage

All data created by the App is stored locally on your device only:

Scanned images are temporarily stored during a scanning session and used to generate PDFs
PDF files are saved to the App's local documents directory on your device
App settings (such as compression quality and capture interval) are stored locally using iOS standard preferences

No data is stored on external servers, cloud services, or any location outside your device.

4. Network Requests

Knut: Book Scanner & PDF makes zero network requests. The App does not connect to the internet for any purpose. It functions fully offline.

No data is uploaded or downloaded
No APIs are called
No remote configuration or feature flags are used
No content is fetched from external sources

Cookies on knut.fi

Cookies are used only on this website. The iPhone app uses none.

The knut.fi website uses Google Analytics 4 so we can see which pages are actually helpful to people and which ones aren't. This is the only analytics tool we use, and it only runs on the website.

Google Analytics loads only after you accept it on the cookie banner. If you haven't accepted, nothing is sent.

What Google Analytics sees when you accept:

Which pages you visit on knut.fi
Which site sent you here (for example, a search engine or a link from another site)
Your approximate location (country and region level, based on your IP address)
The type of device and browser you are using

You can accept or reject analytics at any time. Use the button below to reopen the cookie choice. If you switch from Accept to Reject, we stop sending data immediately and clear the analytics cookies from your browser.

5. Data Sharing with Third Parties

We do not share any data with third parties. There is no data to share because the App does not collect any.

No advertising networks
No analytics providers
No social media integrations
No third-party SDKs that collect data

6. Data Sharing by the User

The App includes a standard iOS share/export feature that allows you to share your PDF files with other apps or services. When you choose to share a file, it is handled by iOS and the receiving app — this is initiated and controlled entirely by you.

7. Children's Privacy

Because Knut: Book Scanner & PDF does not collect any data from any user, it does not collect data from children. The App is rated 4+ and is safe for users of all ages.

8. Security

Your scanned documents and PDFs are protected by your device's built-in security features, including:

iOS file-level encryption
Device passcode, Face ID, or Touch ID protection
iOS sandboxing (the App cannot access data from other apps, and other apps cannot access the App's data)

9. Your Rights

Since we do not collect any personal data, there is no personal data to access, modify, or delete on our end. All your data resides on your device and is fully under your control.

To delete your data: Delete individual PDFs within the App, or uninstall the App to remove all associated data from your device.
To revoke camera access: Go to iOS Settings > Knut: Book Scanner & PDF > Camera.

10. Changes to This Privacy Policy

We may update this privacy policy from time to time. Any changes will be reflected on this page with an updated "Last Updated" date. Continued use of the App after changes constitutes acceptance of the revised policy.

This privacy policy applies to Knut: Book Scanner & PDF for iOS, available on the Apple App Store.
