Privacy Policy

Last Updated: February 24, 2026

Bibliostats ("the App") is developed by Casey Kirst ("we," "us," or "our"). This Privacy Policy explains how the App handles your information.

Summary

Bibliostats is a local-first app. Your reading data stays on your device. We do not have user accounts, do not collect personal information, and do not use analytics or tracking.

Information We Collect

Information You Provide

All data in Bibliostats is entered by you:

• Book information — titles, authors, ISBNs, page counts, cover images, and synopses
• Reading activity — reading sessions, progress entries, start and finish dates
• Ratings — your personal book ratings
• Reading goals — your annual book reading goal
• Imported data — reading history imported from Goodreads or Storygraph CSV exports, processed entirely on your device

Information We Do Not Collect

We do not collect:

• Your name, email address, or any personal identifiers
• Location data
• Device identifiers or advertising IDs
• Usage analytics or behavioral data
• Crash reports

How Your Data Is Stored

On Your Device

All your reading data is stored locally on your device using Apple's SwiftData framework. Book cover images are cached on your device's local storage.

iCloud Sync (Optional, Pro Feature)

If you enable iCloud Sync, your book library and reading progress are synced across your devices through your personal iCloud account. This data is governed by Apple's iCloud Privacy Policy. We do not have access to your iCloud data.

Third-Party Services

The App connects to external services solely to look up book metadata (covers, page counts, and synopses). These requests contain only book search queries (titles, authors, ISBNs) — never your personal information or reading activity.

Book Metadata Services

• Google Books API — used for book search and cover images
• Open Library (openlibrary.org) — used for book metadata lookup
• Hardcover (hardcover.app) — used for book metadata lookup

Apple StoreKit

In-app purchases are processed entirely by Apple through StoreKit. We do not receive or store any payment information. See Apple's Privacy Policy for details.

Data Retention and Deletion

Your data remains on your device for as long as you choose to keep it. You can delete all your data at any time through Settings > Delete All Data within the App, or by deleting the App from your device.

If you have enabled iCloud Sync, deleting data from the App will also remove it from iCloud. You can also manage your iCloud data through your device's iCloud settings.

Children's Privacy

Bibliostats does not collect personal information from anyone, including children. The App has no user accounts, no social features, and no user-generated content sharing.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date.
