AO3 Reader Privacy Policy

Effective date: 19 October 2026

This privacy policy applies to AO3 Reader (Android package com.euanh.ao3_reader), published on Google Play under the developer name BitGlacier. The developer and responsible business is Bit Glacier, operated by Euan Hollidge in the Netherlands (KVK 77946480). Contact: [email protected].

Information used by the app

AO3 Reader lets you browse Archive of Our Own (AO3), download works, read offline, manage your library, and optionally connect your AO3 account. The app stores downloaded works, library and bookmark metadata, reading progress, account metadata, preferences, and story-update information on your device to provide these features. Bit Glacier does not operate a server that receives this reading library or account data from the app.

Connections to AO3 and optional sign-in

The app makes network requests to archiveofourown.org to search, load and download works, retrieve account/library information, and perform actions you request. AO3 receives your IP address, browser/request information, requested URLs and any information you submit to AO3. If you sign in, your credentials are submitted to AO3 through its login page in an embedded browser. Bit Glacier does not receive your AO3 password. Browser cookies and local browser storage can keep your AO3 session signed in on the device and are used for authenticated requests.

AO3 is a separate service operated by the Organization for Transformative Works. Its handling of information is governed by its own privacy policy. AO3 Reader is an independent application and is not an official AO3 or OTW application. Links you open may also take you to external websites with their own privacy practices.

Background checks and notifications

If you enable story-update alerts, the app can periodically contact AO3 in the background using the device's AO3 browser session to check selected stories for changes. It stores update information locally and displays local notifications if you grant notification permission. You can disable alerts in the app and revoke notification permission in Android settings.

Analytics, advertising and sharing

AO3 Reader does not include advertising, analytics or automatic crash-reporting services, and Bit Glacier does not sell your personal information or share your library data for advertising. Network communication with AO3 described above is necessary for the online features you use. If you contact us by email or through our website, we receive the information you choose to send and use it to respond and resolve your request; please avoid sending passwords or session cookies.

Storage, retention and deletion

Local app data is retained until you remove it or clear the app's storage. You can remove downloaded content through the app and disconnect your AO3 session in Settings. Disconnecting clears the browser session; it does not delete your AO3 account or information held by AO3. To remove remaining local app data, use Android's Clear storage option for AO3 Reader. Copies exported outside the app and device/system backups may need to be removed separately. Manage or delete information held by AO3 through AO3 itself. For support correspondence or privacy requests, contact [email protected]; we retain correspondence only as needed to handle the request and applicable recordkeeping obligations.

Security

AO3 connections use HTTPS. Local data is protected by the operating system's app storage controls. No method of storage or transmission is completely secure. Keep your device and operating system updated and protect access to your device.

Changes and contact

We may update this policy when the app or its data practices change. The current policy and effective date remain available at this URL. For questions about AO3 Reader or this privacy policy, contact Bit Glacier (Google Play developer: BitGlacier) at [email protected] or use our contact page.
