Chronica (“the app”, “we”, “us”) is built to be private by default. This policy explains what the app does and does not do with your information.
The short version
- Chronica has no account and no login in this version. You use it anonymously.
- Your reading data — your shelves, reading sessions, chapter notes, ratings, and goals — is stored on your device.
- We do not sell your data, show you ads, or track you across other apps or websites.
What stays on your device
Everything you create in Chronica is stored locally on your device using Apple’s on-device storage:
- The books on your shelves and their status (reading, owned, wishlist, finished)
- Reading sessions, progress, and chapter notes
- Ratings and finished dates
- Your reading goals and streak history
- App preferences (such as the haptics setting)
We cannot see this data. It never leaves your device except as described below.
iCloud sync
If iCloud sync is enabled in a future version, your reading data is synchronized through your own private iCloud account so it can move between your devices. This uses Apple’s iCloud infrastructure. We do not have access to the contents of your iCloud data, and it is governed by Apple’s Privacy Policy.
What is sent to servers
To help you find and add books, the app sends book search queries and book identifiers (such as a title, author name, or ISBN) to:
- Our own book service, which returns book details and cover information
- Third-party book data providers we rely on for that information:
- ISBNdb
- The New York Times Books API
- Open Library
These requests contain only what is needed to look up a book. They do not include your name, your identity, or the contents of your personal shelves, notes, or goals. We do not attach a persistent personal identifier to these requests.
What we do not do
- We do not require or store an account, email, or password in this version.
- We do not use third-party analytics or advertising SDKs.
- We do not track you across other apps or websites.
- We do not sell or rent your personal information to anyone.
Deleting your data
You are always in control of your data:
- Delete all books removes every book and all reading history from your device.
- Reset all data returns the app to a fresh-install state, erasing your library, goals, and preferences.
Because your data lives on your device (and, if enabled, in your own iCloud), deleting it removes it.
Children
Chronica is not directed to children under 13, and we do not knowingly collect personal information from children.
Changes to this policy
We may update this policy as the app evolves. When we do, we will revise the “Last updated” date above. Material changes will be reflected in the app.
