Privacy Policy
Last updated: 11 October 2026 · DuoNoted (package net.duonoted.app)
General
DuoNoted does not require a user account and does not request identifying information (name, email address, payment details). Your texts, books, and cards are stored only on your device. The app relies on limited third-party services for translation and advertising. This policy may be updated; material changes will be communicated within the app.
Translation
In the following cases, the selected text is sent to Google's translation service: automatic translation on the Texts step, and looking up the meaning of a word or phrase while reading. These requests are sent directly from your device to Google; DuoNoted never sees, processes, or stores this data — so there is nothing on our side to delete. How long Google retains this data is governed by Google's own policies.
Ads
The app displays ads via Google AdMob. AdMob may process your advertising ID, IP address/approximate location, and device information for ad delivery and measurement. For details: how Google uses data in advertising.
Users in the European Economic Area, the United Kingdom, Switzerland, and US states with privacy laws are asked for their choices about ad data through Google's consent screen before any ad is shown. You can change that choice later in the app under Settings → Ad privacy choices. You can also reset or delete your advertising ID in your device settings.
Pronunciation
When you listen to a word or sentence, the text is spoken by the text-to-speech engine installed on your device. DuoNoted does not send this text to any server. The data practices of the text-to-speech engine you use are governed by that engine provider's own policies.
What's stored on your device
Drafts, books, cards, and preferences are stored only on your device and are never sent to us. You can delete them at any time via Settings → Your data → "Delete all data," or by uninstalling the app. Deletion is immediate and complete: because none of this data is ever sent to us, we hold no copy of it on any server, and there is no additional retention period on our side.
If you use Settings → Your data → "Back up everything," your books, cards, drafts, and preferences are written to a single file. That file goes only where you choose to put it (for example your device's Documents folder, Google Drive, or email); DuoNoted never sends it anywhere and keeps no copy. Wherever you store it is governed by that service's own privacy terms. "Delete all data" does not delete backup files you have already saved outside the app.
Your rights
We hold no data that identifies you. Users located in the European Union/EEA have the right to access, correct, or delete their data, to object to its processing, and to lodge a complaint with a supervisory authority — however, we hold no data record for these rights to apply to. Requests regarding ad data must be directed to Google.
DuoNoted is not directed at users under the age of 13.
