Privacy Policy

Last updated: March 15, 2026


Qark (“we,” “our,” or “us”) is built on a simple principle: your data belongs to you. This Privacy Policy describes how we handle information when you use Qark, the desktop AI agent kernel.

Qark is a local-first application — everything stays on your device. We do not collect, store, transmit, or have any access to your conversations, files, API keys, or personal data. No account is required to use Qark.

  • Conversations & prompts — Stored locally in a SQLite database on your device. We never see or access them.
  • API keys — Encrypted on disk using a randomly generated key unique to your installation. They never leave your device.
  • Files & documents — Any files processed through RAG or other features remain entirely on your machine.
  • Telemetry & analytics — We collect none. No usage tracking, no crash reporting, no analytics of any kind.

Two narrow, anonymous interactions may occur with our servers:

  • License validation — When you activate a license, your license key and a hardware-derived machine identifier are verified against our licensing server. No personal data is transmitted.
  • Update checks — Qark may periodically check for software updates via a standard HTTP request containing only your app version number. No personal data is transmitted.

Qark is a Bring Your Own Key (BYOK) application. When you use any AI, search, embedding, or reranking provider, your prompts and data travel directly from your device to that provider using your own API keys. Qark does not proxy, intercept, log, or store any of this traffic.

Each provider’s own privacy policy governs how they handle your data. We encourage you to review them:

AI Providers

Search & Web Providers

Embedding & Reranking Providers

All application data is stored locally on your device:

  • Conversations — SQLite database in your application support directory
  • API keys — Encrypted on disk with a per-installation encryption key
  • Settings & preferences — Local configuration files
  • RAG documents — Local vector store on your machine

You are in full control of your data. You can export conversations at any time as Markdown, HTML, or PDF. To delete all data permanently, simply remove the application and its associated support files from your device.

Qark is not directed at children under the age of 13. We do not knowingly collect any information from children. If you believe a child has provided information through our services, please contact us so we can address it promptly.

We may update this Privacy Policy from time to time. Any material changes will be reflected with a new “Last updated” date at the top of this page and announced on our website. Continued use of Qark after changes are posted constitutes your acceptance of the revised policy.
