LilBookworm

A book-series tracker for kids ages 6 to 8, for iPhone. Pick a series, see every book in order, mark each one read.

Privacy policy

Effective 6 November 2026

LilBookworm collects no data. There are no accounts, no ads, no analytics, no tracking, and no in-app purchases.

Everything the app saves stays on your iPhone: reader names and avatars, which books are marked read or want to read, series a grown-up added, and the grown-up PIN. Deleting the app deletes all of it. A grown-up can also remove any single reader from inside the app.

The app talks to one outside service, Open Library, run by the non-profit Internet Archive. It loads book cover images from there, and when a grown-up searches for a book in the locked grown-ups area, the search words are sent there. Like any web request, these include your device's IP address. Nothing about your child or their reading is included, and we receive nothing from these requests. Kids' search works offline and never leaves the device.

Face ID, if a grown-up turns it on, is handled entirely by iOS. The app never sees face data.

We do not knowingly collect personal information from children, and the app has no way to send us any. If a future version changes what the app stores or who it talks to, this page will say so before that version ships.

• Getting into the grown-ups area. On the Me tab, tap Grown-ups area. Enter the PIN, or if none is set, answer the maths question in digits.
• Forgot the PIN. Tap Forgot PIN? and answer the maths question, then set a new PIN inside.
• Face ID doesn't appear. It is a shortcut on top of the PIN. Set a PIN, then turn on the Face ID shortcut in the grown-ups area.
• Removing a reader. In the grown-ups area, under Readers on this device, tap Remove. This erases that reader's marks for good.
• Moving to a new phone. Progress is stored only on the device. An iPhone backup restores it; there is no cloud sync.
