The short version
Silo Bible collects no data. None.
No analytics. No telemetry. No account. No personal data. No usage metrics. No error beacons. No advertising IDs. No fingerprinting. No crash reports. No third-party SDKs. No data of any kind is collected, stored, transmitted, or shared by Silo Bible about you, your device, or your study.
Everything Silo Bible does runs entirely on your iPhone, on-device. There is no cloud component. There is no server. There is no Silo Bible account.
What we don't have, and therefore never see
Because Silo Bible has no server-side component, none of the following exists anywhere in our infrastructure (which consists of: nothing): your name, email, phone, or address; your IP address, device identifier, or any hardware fingerprint; what you read, highlight, note, or ask; session timing, feature usage, or behavioural data; crash reports. The app does not phone home, ever.
Your study stays on the device
All reading data — highlights, margin notes, bookmarks, and reading history — is stored on your iPhone and nowhere else. We have no access to it. Deleting the app deletes it.
AI chat runs entirely on-device
On iOS 26+ devices with Apple Intelligence, Silo Bible's AI chat answers questions from the text of the Bible itself, with verse citations, using the on-device model. Your questions and the answers are processed entirely on the device. Nothing you ask is transmitted anywhere.
Outbound traffic you initiate
The only network traffic Silo Bible ever generates is user-initiated, and none of it identifies you:
- Translation and voice-pack downloads. When you choose to download a Bible translation (open-licensed and public-domain editions such as the World English Bible, KJV, ASV, and 1,000+ languages via eBible.org) or an offline voice pack, the files are fetched as anonymous downloads from a public CDN. No token, account, or registration is required. Once the packs are on the device, Silo Bible works fully offline.
- App Store updates.When Apple ships a Silo Bible update, the App Store delivers it. This traffic is between your iPhone and Apple's servers. Silo Bible is not involved.
- Links you tap. If you tap an external link inside the app, your browser handles the request. Silo Bible is not involved.
Third-party components
Silo Bible embeds no third-party SDKs — no analytics, no ads, no crash reporting, no tracking of any kind. The open-licensed and public-domain scripture texts and open-source voices it downloads are static content; the sources that host them receive no data about you from Silo Bible beyond the anonymous download request itself.
Children's privacy
Because no personal data is collected from any user, no special treatment is required for users under 13. Same policy applies regardless of age: nothing collected.
Changes
If we ever materially change how Silo Bible handles data, we will publish an updated version of this page, announce the change prominently in the release notes, and require explicit consent in-app before any new collection begins. The current policy is: nothing is collected.
