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 or Mac, 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 never phones home to Silo Systems; direct network use is limited to downloads you request and links you open.
Your study stays on the device
Highlights, margin notes, bookmarks, and reading position stay in the local study database on that device. Version 1.1.0, which is in preparation and not in the current App Store build, adds local reading plans, completion history, and verse-memory cards and reviews. We have no access to this data. Silo Bible has no account or sync service.
AI chat runs entirely on-device
On supported Apple Intelligence devices, Silo Bible's AI chat answers from installed translations with tappable verse citations, using the on-device model. Your questions and the answers are processed entirely on the device. Nothing you ask is transmitted anywhere; unsupported devices show an availability explanation instead of a cloud fallback.
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 from the in-app public catalog) 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 device 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.
Optional notifications in version 1.1.0
This feature is in preparation and is not in the current App Store build. If you enable a daily reading reminder, Silo Bible schedules it locally. Lock-screen text is generic and contains no scripture, notes, plan title, or reading history. You can decline or revoke notification permission at any time without affecting reading plans or verse memory.
Third-party components
Silo Bible embeds no analytics, advertising, crash-reporting, or tracking SDKs. 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.
