Who we are

Marg is an app made by Margapp, an independent developer project. The app is made for iPhone and Android, and is designed as a reading companion for people who want to save quotes and words while they read.

What data do we collect?

We don't collect any personal data. Marg has no:

• User accounts or login
• Servers that receive data from your app
• Analytics or tracking tools
• Advertising or third-party data collection
• Access to contacts, calendar, microphone or other sensitive permissions

What is stored on your device?

All content you create in Marg is stored locally on your phone using the device's standard storage mechanism:

• Quotes you have saved
• Words you have saved from the Norwegian and English dictionaries
• Books you have added to your shelf
• Cover photos you take or choose for your books
• Quotes friends have traded with you

Camera and photo access

Marg asks for the camera when you use it: to photograph a book page to save a quote, to look up a word from a photo, to scan a book's barcode, to take a picture of a book's cover, or to scan a friend's code when you trade margins. Marg can also open your photo library, but only to the picture you pick yourself.

Photos of pages are used only for text recognition on the device itself. They are not stored, not sent to any server, and not used for anything else. A cover photo you choose is saved on your device as that book's cover, and nowhere else.

Trading margins with a friend

When you trade margins, your phone shows a code that your friend scans with their camera, and the other way round. Nothing goes through the internet or through any server: it travels only from one screen to the other camera.

The code contains only:

• The name you choose to show your friend
• A random identifier, so your friend's phone recognises you if you trade again
• The book's title, author and ISBN
• The quotes you chose to share, with their page numbers

Your friend's quotes are saved only on your phone, and you can remove them from a book at any time.

Internet access

The app uses the internet for three things:

• Fetching dictionary data from ordbokapi.org (the Norwegian dictionary) when you search for a Norwegian word
• Fetching dictionary data from dictionaryapi.dev (the English dictionary) when you search for an English word
• Fetching book information and covers from Open Library when you scan a barcode, search for a book, or look for a cover

These are publicly available services and receive only the search terms you type. We have no affiliation with them beyond standard API usage.

Third-party libraries

Marg uses the following third-party library for on-device text recognition:

• Google ML Kit (text recognition) runs locally on your device. No data is sent to Google.

Children

Marg does not collect data from any users, including children. The app is not specifically directed at children under 13.

Changes to this policy

If we make changes to this privacy policy, the updated version will be published on this page with a new date. Since Marg doesn't collect data, this is unlikely to change significantly.
