OVERVIEW
--------
BookFlow does not collect, store, transmit, or share any personal information.
We are committed to your privacy. This policy explains what the app does and
does not do with respect to your data.
PERSONAL INFORMATION
--------------------
BookFlow does NOT access, collect, or transmit any personal information.
No data that could be used to identify you as a person is ever collected.
WHAT THE APP STORES LOCALLY (ON YOUR DEVICE ONLY)
--------------------------------------------------
The following data is saved only on your device using Windows local storage.
It is never sent to any server or third party:
- Your reading preferences (font size, theme)
- Your app theme setting (light / dark / system)
- Your in-app star rating selection
- Reading progress and library metadata for ebooks you add
EBOOK FILES
-----------
Ebook files (.epub, .pdf, .txt) that you add to your personal library are
stored locally on your device. BookFlow does not upload or transmit these
files to any external server, except when you use the optional Format
Converter feature (see below).
FORMAT CONVERTER (OPTIONAL FEATURE)
------------------------------------
If you choose to use the Format Converter, your selected ebook file is
temporarily sent to CloudConvert (cloudconvert.com) for conversion.
CloudConvert processes the file and returns the converted result.
BookFlow does not retain a copy of your file during or after this process.
Please review CloudConvert's own privacy policy at:

INTERNET CONNECTIONS
--------------------
BookFlow may make the following outbound network requests:
- Fetching free public domain ebook covers and metadata from
Project Gutenberg (gutenberg.org) — no personal data is sent.
- Loading the Discover Books catalog from the app's local data file.
- Opening Amazon.com product pages in your system browser when you
tap "View on Amazon" in the Shop Books section. Your browser's
own privacy policy applies once you leave the app.
AMAZON AFFILIATE DISCLOSURE
----------------------------
BookFlow participates in the Amazon Associates Program. When you tap
"View on Amazon," your system browser opens an Amazon product page
that includes the affiliate tag. This does not
transmit any personal information from within the app.
CHILDREN'S PRIVACY
-------------------
BookFlow does not knowingly collect any information from children or
any other users, as no personal data is collected at all.
CHANGES TO THIS POLICY
-----------------------
If this policy changes in a future update, the updated policy will be
included with the app update and the "Last Updated" date above will reflect
the change.

If you have any questions about this privacy policy, you can contact the
