Three questions worth asking about any reading tracker
How do books get in?
If adding a book takes a minute of typing, the log will not survive contact with a busy month. Barcode scanning and catalogue search are not conveniences here — they are the difference between a habit and an abandoned app.
How do books get out?
Ask before you start, not after three years. Can you export everything, in a format something else can read, without paying? If the answer is no, you are not keeping a record — you are renting one.
Who else can see it?
A reading history is a surprisingly personal document: illness, grief, faith, sexuality and everything you were curious about at two in the morning are all visible in it. It is reasonable to want that private by default rather than private by configuration.
BooksLove answers those three like this: books come in by camera or search, everything goes out to CSV or JSON free at any time, and there is no account and nowhere to publish — your shelves are private from the first launch. The Privacy Policy names every outside service the app talks to.
