1. Consyllus Desktop Application: Zero Telemetry & Local-Only Progress

The Consyllus desktop application does not collect any telemetry, crash reports, behavioral analytics, or usage logs. You do not need to register an account, provide an email address, or sign in to use the application.

Your personal study progress (progress.json—including completed nodes, current study target, error logs, and difficulty notes) and custom node layout coordinates (.graph.axis.json) are stored strictly in your local Vault directory on your device and are never uploaded to any cloud server.

2. Self-Hosted Cryptographic Identity & Public Graph Hub

When you initialize Consyllus, an Ed25519 keypair is generated locally and encrypted via your operating system keyring (Windows DPAPI, macOS Keychain, or Linux Libsecret). Your private key and 16-byte entropy never leave your device.

Browsing and downloading graphs from the Public Graph Hub are performed via static CDN requests without cookies, authentication headers, or download telemetry. Only when you explicitly choose to sign and publish an objective curriculum graph (graph.json and optional outline.json) to the Hub are your public key (author_id), chosen creator profile (display name and bio), and the signed graph submitted.

3. Website Analytics (Cloudflare Web Analytics)

On our public website, we use Cloudflare Web Analytics to measure aggregate, privacy-preserving traffic metrics (such as page views and referrers). Cloudflare Web Analytics does not use cookies, does not use localStorage for tracking, does not fingerprint individuals across sites, and does not collect personal data. During preview stages before public launch, web analytics are disabled entirely.
