Bookwick Privacy Policy

Effective date: 2026-11-14

Bookwick is a reading tracker: you add the books you read, log the page you are on (or a percentage), time your reading sessions, see a reading calendar, streak and statistics, save quotes, and get an optional evening reminder and a home screen widget (the "app"). It is provided by DDJ A1 ("we", "us"). This policy explains what data the app handles and how. Bookwick has no account system and we do not run a server for it.

Data stored on your device

The books you add (title, author, number of pages, shelf, rating), your reading records (dates, pages, minutes), your quotes, your goals and your settings are stored only on your device. They are not sent to us. Deleting a book or record in the app removes it, and uninstalling the app deletes all of this data from your device. If device backup is turned on, Android's standard app backup may include this data in your own Google account backup. That backup is controlled by you and Google, not by us.

Backup files

When you tap Save a backup file, the app writes your books, records and quotes to a file at a location you choose with the Android file picker. When you tap Restore from a backup file, the app reads the file you pick. The app does not upload these files anywhere; where you keep them is up to you.

Book search and covers

When you search for a book, the words you type (a title, author or ISBN) are sent to the public book catalogues Open Library (openlibrary.org, run by the Internet Archive) and, if Open Library returns nothing, Google Books (googleapis.com), so they can return matching titles, page counts and cover images. When you add a book from the results, the app downloads its cover image once and keeps it on your device. These services receive your search words and, like any website, your device's IP address; their own privacy policies apply (https://archive.org/about/terms and https://policies.google.com/privacy). The app does not send your reading records, quotes or any other data with these requests. You can always add a book by typing the details yourself, without searching.

Sharing

When you tap Share on a quote or share the app, the app opens the Android share sheet with a short text. Nothing is sent unless you choose an app to share it with; what happens next is up to that app.

Permissions the app asks for and why

• Notifications (optional). Used for a gentle reading reminder. You can decline and every feature still works.
• Run at startup. Lets reminders come back after your phone restarts or the time zone changes.
• Vibration. Used for reminder notifications (you can turn it off).
• Internet access, network state and the advertising identifier (AD_ID). Used for book search and covers as described above and by the advertising components described below. Logging your reading works offline.

The app does not request your location, the camera, microphone, contacts, or access to your photos, media or other files.

Information collected automatically

When you use the app, third-party SDKs used for advertising may collect some information automatically, including:

• Your device's Internet Protocol (IP) address, which may be used to estimate your approximate (general) location
• Device or other identifiers, such as your device's advertising identifier (Advertising ID) and app set ID
• App interactions, such as session time, screens viewed, and ad views and taps
• Crash logs and diagnostic information, such as your device's operating system and model, and ad performance data

The advertising SDK collects this information and shares it with Google (AdMob) and its advertising partners for advertising, analytics, fraud prevention, security and compliance. It is encrypted in transit. The app itself does not send the books, reading records or quotes you enter to us or to advertisers, and we do not link the advertising data to them.

Advertising

The app shows advertisements from Google AdMob:

• a banner at the bottom of the screens
• an ad when the app starts from the launcher
• full-screen ads only at a few moments: after you save a book, and after you save a reading record
• an ad in the exit dialog
• optional video ads you can choose to watch from Settings to see fewer ads for 24 hours

A full-screen ad never appears while you are typing, while the reading timer is running, when you switch tabs, or when you open the app from the widget or a notification. To serve ads, AdMob and its partners may access your device's Advertising ID and the information described above. In the European Economic Area (EEA), the United Kingdom and other regions where required, the app shows a consent form through Google's User Messaging Platform (UMP) before personalized advertising data is used. If you decline, you are shown non-personalized ads instead. You can reset or limit ad personalization at any time in your device settings (Settings → Google → Ads), and you can change your consent choice from the app's Settings screen.

For more information on how Google uses data when you use partners' apps, see https://policies.google.com/technologies/partner-sites.

Children

Bookwick is a general-audience app and is not directed to children under 13. We do not knowingly collect personal information from children.

Your rights

Your app data exists only on your device, so you control it directly: you can edit or delete any book, record or quote in the app, and uninstalling the app removes everything the app stored. Depending on where you live (for example under the GDPR in the EEA/UK or the CCPA in California), you may also have rights over data processed by advertising SDKs. You can exercise your ad choices through the consent form and your device's ad settings described above.

Changes

We may update this policy. Material changes will be reflected on this page with a new effective date.
