Colophon — Privacy Policy

Last updated: 2026-07-10

Colophon is a private, offline study Bible. This policy explains, plainly, what the app does with your information. The short version: nothing leaves your device, because there is nowhere for it to go.

We collect nothing

Colophon has no servers, no accounts, and no sign-in. We do not collect, transmit, store, sell, or share any personal information. There is no analytics, no advertising, no tracking, and no crash reporting. The app makes no network requests to us — there is no “us” on the other end of a connection.

Your study stays on your device

Everything you create in Colophon — your notes, highlights, bookmarks, and notebooks — is stored only in a private database on your device. We never see it. It is not uploaded anywhere.

Backups are files you control

The Pro “Backup & Restore” feature writes a single file containing your study and hands it to your device’s share sheet (Files, a drive, AirDrop, email to yourself, or wherever you choose). Colophon keeps no copy of that file, no history, and no destination, and it never transmits it. The backup file is unencrypted, so anyone who holds it can read it — keep it as you would a paper notebook. What happens to the file after you save or send it is governed by whatever service you chose (for example, iCloud Drive or Google Drive), under their privacy policies, not ours.

Purchases

Colophon offers a one-time Pro unlock and optional tips through the App Store and Google Play. Those purchases are handled entirely by Apple and Google. We do not receive or store your payment details. Apple’s and Google’s privacy policies govern that transaction.

Bible text and study data

The Scripture texts and study data bundled with the app (translations, the original-language lexicon, cross-references) are public-domain or openly-licensed resources included in the app itself. Using them involves no data collection.

Children

Colophon collects no data from anyone, including children.

Changes

If this policy ever changes, the updated version will be posted here with a new date. Because the app collects nothing, we do not expect material changes.
