**No, OpenLogi does not collect telemetry data.** The application is explicitly architected as a local-first, account-free hardware configuration tool where all user data remains stored in plain-text TOML files on your local machine, with no analytics, usage statistics, or diagnostic information transmitted to external servers.

When evaluating open-source hardware configurators, privacy-conscious users need concrete evidence that their device mappings and settings remain private. According to the AprilNEA/OpenLogi repository, this Rust-based application maintains a strict privacy-first design that deliberately excludes any telemetry-related services across its core configuration modules, desktop implementations, and packaging definitions.

## Evidence from the Source Code

The OpenLogi codebase contains multiple explicit declarations confirming the complete absence of telemetry collection mechanisms.

### Project Documentation and Philosophy

The repository's [`AGENTS.md`](https://github.com/AprilNEA/OpenLogi/blob/main/AGENTS.md) file establishes the project's foundational privacy stance directly. At line 5, the documentation states the core philosophy: **“no account, no telemetry, plain-TOML”**. This declaration confirms that OpenLogi operates without user tracking, account requirements, or encrypted binary configuration formats that could obscure data transmission.

### Core Configuration Module

In [`crates/openlogi-core/src/config/settings.rs`](https://github.com/AprilNEA/OpenLogi/blob/main/crates/openlogi-core/src/config/settings.rs), the configuration architecture reinforces these privacy guarantees. Line 70 contains a comment explicitly referencing the README’s promise of **“no telemetry, no auto-update poller”**, demonstrating that privacy considerations were integrated into the settings management layer from the initial design phase. This module handles all user preferences—including DPI presets, button mappings, and lighting profiles—without any network-dependent persistence mechanisms.

### Windows Update Consent Implementation

For Windows users, the implementation in [`crates/openlogi-desktop/src/windows/update_consent.rs`](https://github.com/AprilNEA/OpenLogi/blob/main/crates/openlogi-desktop/src/windows/update_consent.rs) (lines 3–108) provides granular transparency regarding network activity. This module confirms that update checks are **off by default**, and explicitly guarantees **“no automatic download or telemetry”** when processing software updates. The code ensures that even when users opt into version checking, the process remains strictly limited to fetching version metadata without transmitting system information or usage patterns.

### Linux Packaging Configuration

The telemetry-free stance extends to distribution packaging. The [`packaging/linux/nfpm.yaml`](https://github.com/AprilNEA/OpenLogi/blob/main/packaging/linux/nfpm.yaml) file includes a declarative comment at line 18 stating simply **“no telemetry”**, ensuring that Linux package maintainers and end users understand the application transmits no data during installation, operation, or removal.

## Local Data Storage Implementation

Unlike cloud-dependent alternatives, OpenLogi persists all configuration data locally using human-readable TOML files. The following Rust code demonstrates how the application loads user configurations without initiating network connections:

```rust
use openlogi_core::config::Config;

// Load the TOML configuration from the default location.
// No network calls are made during this process.
let cfg = Config::load_default().expect("Failed to read config");
println!("Current config: {:#?}", cfg);

```

This local-first approach ensures your hardware profiles remain in standard filesystem locations—such as `~/.config/openlogi/` on Linux—using auditable plain-text syntax rather than proprietary databases or remote APIs.

## Configuring Network Features for Maximum Privacy

While OpenLogi supports optional update checks, this represents the sole potential network activity in the application, and it remains strictly telemetry-free. To guarantee complete network isolation, users can explicitly disable this feature in their configuration file:

```toml

# In your OpenLogi TOML config (e.g., ~/.config/openlogi/config.toml)

[app_settings]

# Keep update checks turned off – this also guarantees no telemetry.

auto_update = false

```

Setting `auto_update = false` prevents all server communication, creating an air-gapped configuration environment where your hardware settings remain completely isolated from external networks.

## Summary

- **Zero telemetry architecture**: The codebase contains no analytics collection logic, as verified across [`AGENTS.md`](https://github.com/AprilNEA/OpenLogi/blob/main/AGENTS.md), [`crates/openlogi-core/src/config/settings.rs`](https://github.com/AprilNEA/OpenLogi/blob/main/crates/openlogi-core/src/config/settings.rs), and platform-specific implementation files.
- **Plain-text local storage**: All user data persists in TOML configuration files without cloud synchronization, encryption, or proprietary formats.
- **Opt-in networking only**: The update checking feature is disabled by default and can be permanently turned off via the `auto_update` configuration setting.
- **Cross-platform consistency**: Both Windows ([`update_consent.rs`](https://github.com/AprilNEA/OpenLogi/blob/main/update_consent.rs)) and Linux ([`nfpm.yaml`](https://github.com/AprilNEA/OpenLogi/blob/main/nfpm.yaml)) implementations maintain identical no-telemetry guarantees.

## Frequently Asked Questions

### Does OpenLogi require an account to use?

No. According to the [`AGENTS.md`](https://github.com/AprilNEA/OpenLogi/blob/main/AGENTS.md) documentation, OpenLogi operates with **“no account”** requirements. The application functions entirely offline without user registration, authentication tokens, or cloud synchronization mechanisms.

### What data format does OpenLogi use for storage?

OpenLogi uses **plain-text TOML files** for all configuration persistence. This includes device profiles, macro definitions, and application preferences stored in standard user configuration directories without encryption or binary encoding.

### Can OpenLogi auto-update, and does it collect data during updates?

Update checking exists as an opt-in feature that is **off by default**. As implemented in [`crates/openlogi-desktop/src/windows/update_consent.rs`](https://github.com/AprilNEA/OpenLogi/blob/main/crates/openlogi-desktop/src/windows/update_consent.rs), the update mechanism explicitly promises **“no automatic download or telemetry.”** When disabled via `auto_update = false` in your TOML configuration, the application makes no network connections.

### Where does OpenLogi store my hardware configuration files?

Configuration files are stored in platform-specific directories following the XDG Base Directory specification on Linux and equivalent system standards on Windows and macOS. All settings use human-readable TOML syntax, allowing manual editing and version control without proprietary database dependencies.
