This Privacy Policy explains how information is handled in connection with Leafcairn, an Android application provided by 40ktech AS, Skogsåsen 32A, 1412 Sofiemyr, Norway (“we”, “us”, or “our”).
Application: Leafcairn
Package name: com.leafcairn.readingstudio
Privacy contact: [email protected]
1. Our approach to your privacy
Leafcairn is a personal reading journal that works without an account. Your books, reading records, notes, goals, and preferences are stored locally on your device.
We do not receive your journal content through the application. Leafcairn does not include advertising, analytics services, or automatic crash-reporting services.
The application uses internet access only to open the website displaying this Privacy Policy. Opening that website and contacting us by email involve separate processing, explained below.
2. Information processed on your device
Leafcairn processes the information you enter and the records created when you use its reading features:
| Information | Purpose |
|---|---|
| Book titles, authors, page counts, shelves, tags, colours, ratings, and reviews | Organise and display your personal library |
| Reading session dates, durations, page ranges, reflections, and timer state | Maintain your reading journal and ongoing sessions |
| Page positions, notes, quotations, questions, bookmarks, and starred items | Preserve your reading progress and personal observations |
| Queue order, intended finish dates, and reading goals | Help you plan your reading |
| Recorded reading activity and calculated summaries | Display reading estimates, activity, progress, and streaks |
| Application preferences | Remember your chosen settings |
These records remain in the application’s local storage. They are not uploaded to our servers, published, or made available to other users by Leafcairn.
Free-text entries may contain personal information depending on what you choose to write. You control the content you enter. Providing your name, email address, date of birth, or identity documents is not required to use the application.
3. Information we receive
Support correspondence
If you contact us, we receive your email address, your message, and any attachments or other information you choose to provide. Email correspondence also includes technical information used to deliver the message.
We use this information to respond, investigate the issue you report, and handle privacy requests. Sending a support message does not give us access to the journal stored on your device.
Please provide only information relevant to your request. You do not need to send your reading journal to ask a general question.
Access to the privacy policy website
When you open the privacy policy website, your browser or the application’s webpage viewer sends connection information to the infrastructure serving the page. This includes your IP address and may include the requested URL, request time, browser type, and operating system information.
This information is used to deliver the page and may be processed by the hosting infrastructure for operation and security. Leafcairn does not include your journal content in requests to open this page.
This website connection is separate from the application’s local reading features. The statement that your journal stays on your device does not mean that visiting a website is anonymous.
4. Advertising, tracking, and device access
Leafcairn does not:
- Display advertisements or integrate advertising SDKs.
- Use analytics or automatic crash-reporting SDKs.
- Use advertising identifiers to recognise or profile you.
- Track your activity across other applications or websites.
- Upload your reading activity or journal content.
The application does not request access to your contacts, precise location, camera, microphone, SMS messages, or shared files. It uses application storage to retain the records and settings needed for its features.
5. Why information is processed
Information stored on your device is used to provide the reading journal functions you choose to use. We do not receive or repurpose that content for marketing, analytics, or other company activities.
For personal information we receive through correspondence or website operations, the relevant purposes and legal bases under applicable European data protection law are:
- Responding to enquiries and providing support: our legitimate interest in answering users and resolving application issues.
- Making privacy information available and maintaining website security: our legitimate interest in operating an accessible, reliable privacy policy page.
- Meeting applicable legal requirements: compliance with a legal obligation.
- Handling disputes or legal claims, where necessary: our legitimate interest in establishing, exercising, or defending legal rights.
Where we rely on legitimate interests, those interests must be balanced against your rights and freedoms, taking particular care where the information concerns a minor.
6. Disclosure of information
We do not sell personal information or disclose it for targeted advertising.
Your locally stored journal is not shared with us or our service providers by the application.
Providers of email delivery, website hosting, and related infrastructure may process correspondence or website connection information as necessary to supply those services.
We may disclose information we actually hold where required by law or a valid legal process, or where necessary to establish, exercise, or defend legal claims. This does not give us access to journal content stored only on your device.
7. Storage, retention, and deletion
Your reading journal
Your journal and preferences remain on your device until the relevant records or the application’s stored data are removed. We do not apply a server-side retention period to your journal because we do not hold a server-side copy.
You can remove all locally stored Leafcairn data through Android settings:
Settings → Apps → Leafcairn → Storage or Storage & cache → Clear storage or Clear data.
The names of these options vary by device. Clearing storage resets the application and removes its local journal and preferences. Uninstalling Leafcairn normally also removes its private application data.
We cannot recover deleted journal content because we do not receive a copy.
Leafcairn is configured not to participate in standard Android cloud backup. Device migration and manufacturer-provided backup tools may operate differently. Any independently created copies must be managed through the relevant device or backup service.
Correspondence and website records
Information received outside the local journal is retained only for as long as necessary for the purpose for which it is processed.
Relevant criteria include whether a support request remains open, whether follow-up is reasonably needed, the operational or security need for technical records, and any applicable legal retention or limitation periods.
A privacy request may also be retained to document how it was handled. When information is no longer needed, it should be deleted or anonymised.
8. Security
Leafcairn keeps your journal in local application storage and relies on Android’s application isolation and device security protections. Your device settings and the security of your operating system affect the protection of these records.
Use a screen lock and keep your device software up to date. Anyone who can unlock your device may be able to open the application and view your journal.
No application, device, or communication system can guarantee absolute security. If you contact support, avoid sending unnecessary sensitive information.
9. International processing
Leafcairn does not upload your journal to another country or to a remote server.
Support correspondence and website connection information may be processed where the relevant email and hosting infrastructure operates. Any transfer subject to European data protection restrictions requires an applicable lawful transfer mechanism, such as an adequacy decision or appropriate contractual safeguards.
You may contact us for information about the processing locations and safeguards applicable to information we hold about you.
10. Your rights and choices
You control the journal stored on your device through Leafcairn and Android’s storage settings. We cannot remotely retrieve, edit, export, or erase that journal.
For personal information we hold, applicable law may give you the right to:
- Request access to your information.
- Request correction of inaccurate information.
- Request deletion.
- Request restriction of processing.
- Object to processing based on legitimate interests.
- Receive information in a portable format where the legal conditions apply.
These rights depend on the circumstances and are subject to applicable legal exceptions.
Send requests to [email protected]. We may need proportionate information to verify your identity. We will respond within the period required by applicable law.
You may complain to the data protection authority in your country of residence, place of work, or the place of an alleged infringement. Our national supervisory authority in Norway is Datatilsynet.
There is no application account to delete. Removing your local journal does not require contacting us.
11. Privacy of younger users
Leafcairn’s audience includes teenage users. The application does not require registration or submission of identifying information, and the same local storage practices apply to their journals.
We do not use journal entries for advertising, profiling, or monitoring younger users.
If a young user or a parent or guardian has a privacy concern, they may contact us at [email protected]. If personal information has been sent to us through support, we will assess any request concerning it in accordance with applicable law and the young person’s rights.
12. Changes to this policy
We may update this policy when the application’s features, information practices, or applicable requirements change. The revised version will display an updated date.
Where required, we will provide additional notice or obtain consent before introducing new processing. Posting an updated policy does not, by itself, constitute consent.
