Nefha Notal Privacy Policy

Last updated: 19 September 2026

  • You do not need an account to use Notal.
  • Your books, highlights and notes stay on your device. We have no app database and never see your notes.
  • If you turn on backup, your data goes to your own Google Drive, into a hidden folder only Notal can reach.
  • No ads, no tracking cookies, no usage analytics. We do not sell or share your data.
  • To find covers and book details, a title, author or ISBN is sent to the services listed below. Your notes and highlights are not.

1. Who we are

Notal is a book notes and library app made by Nefha. This policy covers the web version (notal.nefha.app) and the iOS and Android apps. "We" means Nefha; "you" means the person using the app.

2. Data kept on your device

Your library (books, highlights, notes, tags, shelves, reading status and cover images) is stored in your device's app storage: the browser's own storage on the web, the app's own storage on mobile. It never reaches our servers.

Files you import (such as a Kobo e-reader's database or PDF files) are read on your device. The file itself is not uploaded anywhere; only the book details, highlights and notes found in it are added to your library.

Also kept on your device: a randomly generated device ID (to tell which device a backup came from), your language and display preferences, and, if backup is on, your Google session token.

3. Google User Data Policy & Drive Backup

When you enable cloud backup, you sign in with your Google Account. Nefha Notal accesses and processes the following Google user data:

How We Use and Store Google Data

Your library backups are transferred directly from your device to your personal Google Drive via Google's official APIs. Nefha does not host an intermediate application server or database; your Google credentials and library data never pass through or get stored on any third-party or Nefha servers.

Sharing, Retention, and AI Training Prohibition

Nefha Notal's use and transfer to any other app of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

4. What is sent to outside services

Some features need to ask a service on the internet. Like any internet connection, these services can see your device's IP address and browser details.

ServiceWhat forWhat is sent
Google Books API (Google)Finding covers and book details, filling in the form from an ISBNThe ISBN, or the title and author
Open Library (Internet Archive)Finding coversThe ISBN
Rakuten Kobo (cdn.kobo.com)Showing covers of Kobo booksKobo's cover image ID
Notal ISBN search helper (on Cloudflare) and Brave SearchSearching the web for an ISBN Google Books does not knowOnly the ISBN. The question goes to our helper first; it asks Brave for the ISBN alone and does not pass your IP address to Brave.
Google Fonts (Google)Loading the app's typefaces (web)Only the font request
CloudflareHosting the web version and the ISBN search helperPage and search requests

Our ISBN search helper stores nothing: neither who asked nor the answer. To limit abuse, Cloudflare briefly counts how many questions arrive from one IP address per minute.

These services have their own privacy policies: Google, Internet Archive, Rakuten Kobo, Brave, Cloudflare.

5. What we do not use

6. Purchases

When paid features arrive, payment will go through the App Store or Google Play. We will never see your card details. Before those features ship, this page will list what information goes to which service.

7. Deleting your data

8. Your rights

You can write to us to exercise your rights over your personal data, including under Turkey's Personal Data Protection Law (KVKK, No. 6698) and the EU General Data Protection Regulation. Because your data lives on your device and in your Drive rather than with us, you can do most of this yourself with the steps above.

9. Children

Notal is not directed at children and does not knowingly collect personal data from children.

10. Changes

If we change this policy, we will publish the new version on this page with a new date, and announce important changes in the app.
