The short version
Coil 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 data of any kind is collected, stored, transmitted, or shared by Coil about you, your device, or your content.
Everything Coil does runs entirely on your Mac, on-device, using a bundled local runtime and locally-stored open-weights models. There is no cloud component. There is no server. There is no Coil account.
What we don't have, and therefore never see
Because Coil 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; your content and anything derived from it; session timing, feature usage, or behavioural data; crash reports. The app does not phone home, ever.
Outbound traffic you initiate
The only outbound network traffic, all user-initiated, and none of it to Coil:
- Model weight downloads. After onboarding, Coil offers to download model weights from public open-weights repositories (Hugging Face). The download is anonymous by default; no token, account, or registration is required. Once the weights are on disk, Coil works fully offline.
- App Store updates.When Apple ships a Coil update, the App Store delivers it. This traffic is between your Mac and Apple's servers. Coil is not involved.
- Links you click. If you click an external link inside the app, your default browser handles the request. Coil is not involved.
Permissions we request, and why
- Folders you choose. Standard sandboxed file access; the app reads only what you explicitly select.
Coil does not request Camera, Contacts, Location, or Full Disk Access beyond what is listed above. If you grant nothing, it can read nothing.
On-device data you create
Your content and everything derived from it live on your disk under ~/Library/Containers/com.silosystems.coil/Data/Library/Application Support/Coil/ (plus any folder you explicitly choose to export to). They are yours. We do not have access to them. Deleting Coil removes the app; your work remains under its container until you delete it manually.
Third-party components
Coil uses these open-source components and public services. None of them receive any data about you from Coil:
- mlx-swift-lm — runs locally on-device.
- qwen3.5 — runs locally on-device.
- qwen3-embedding — runs locally on-device.
- Qwen chat, router, and embedding models (MLX) (Hugging Face) — downloaded on demand, runs locally.
- Hugging Face Hub / ModelScope — contacted only when you choose to download model weights.
Children's privacy
Coil is rated 4+. 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 Coil 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.
