Privacy policy

Privacy is a feature, not a footnote. Here is exactly how Tengan handles your data.

Your data stays with you.

Tengan runs inside your network, so the policy is short.

  • On-premise by default

    Tengan runs on your infrastructure. No cloud, no SaaS: no data ever leaves your network.

  • Zero telemetry

    We don't phone home. No analytics, no tracking pixels, no usage metrics shipped to us.

  • Local storage only

    User accounts, session metadata and audit logs are stored on your deployment alone.

  • No third-party sharing

    We don't share, sell or transmit your data to third parties. Period.

What we collect.

Only the minimum the platform needs to operate, stored only on your deployment.

  • User account information: username, email and hashed passwords.
  • Session metadata: timestamps, host IDs and user IDs.
  • Audit logs of system events.
  • Encrypted credential vault entries.

Your rights.

You have full control over your data. Export, change or delete anything stored in your Tengan deployment at any time. Because Tengan runs on-premise, you don't need to ask us: the controls are yours.

Questions about your data?

We respond to every privacy inquiry personally.
