Privacy Policy

Privacy Policy (Docluno)

Effective date: January 29, 2026

Docluno is a Lightball Labs production. This Privacy Policy explains what information Docluno processes and why.

1. Summary

Docluno is designed to keep things simple and privacy-friendly.

  • Your documents and generated study content are stored locally on your device.
  • If you use OCR, the selected file is uploaded to our OCR endpoint so we can extract text and return it to you.
  • We do not require an account to use the app.

2. Who is responsible for the data

Controller: Lightball Labs
Contact: hello@lightballlabs.com

3. What information we process

A. Content you create in the app

Docluno can store the following locally on your device:

  • Documents you save, such as title and text
  • Generated study content, such as quiz questions, flashcards and summaries tied to a document
  • App settings, for example language choice

This is stored to make the app work properly, including offline use.

B. OCR uploads

If you scan with the camera or import an image/PDF and run OCR:

  • The selected file is uploaded to our OCR endpoint
  • The service returns extracted text, which is then shown inside the app

We process OCR uploads only to provide the feature you requested.

Our OCR endpoint is hosted on Google Cloud infrastructure in europe-north1, Finland.

4. Permissions

Docluno may request:

  • Camera access for scanning
  • Photo library access if you choose images
  • File/document access if you import PDFs

You can choose not to grant these permissions and instead paste text manually where applicable.

5. Sharing and third parties

We do not sell your personal information.

We may share limited data only when needed to provide the app's features, for example:

  • OCR processing provider and hosting infrastructure used to extract text from your file
  • Platform providers such as Apple, Google and your device operating system for app distribution and core platform functionality
  • Crash reporting provider, if enabled in the app, such as Sentry, to collect technical diagnostics like device type, OS version, app version and error logs

6. Legal basis

If you are in the EEA or UK, we rely on:

  • Performance of a contract to provide the app features you request
  • Consent or your request for optional processing such as OCR uploads

7. Data retention

  • Local documents remain on your device until you delete them in the app or uninstall the app
  • OCR files are processed to extract text and are not stored after processing is completed

8. Your choices and rights

Depending on where you live, you may have rights to access, correct or delete your information, object to processing, request restriction, request portability, or file a complaint with your local data protection authority.

Because Docluno does not require an account, we may not always be able to identify you unless you contact support and provide enough detail.

9. Children

Docluno is not intended for children under 13. If you believe a child has provided information through the app, please contact us and we will address it.

10. Changes to this policy

We may update this Privacy Policy from time to time. We will update the effective date at the top when we do.
