Privacy & cookies

Cookies we set

• np_consent — stores your banner choice (essential, all, or reject). First-party, not HttpOnly, about 1 year. Required for the site to know whether it may place the guest device cookie below.
• np_qd — random UUID for anonymous visitors who choose Essential or Accept all. HttpOnly, first-party, long-lived. Used with your IP address to limit free generations per day without an account.
• Supabase auth — when you sign in, Supabase sets session cookies so you stay logged in. See Supabase privacy.

If you reject optional cookies

Choosing Reject optional keeps only what is needed to record that choice. Guest AI quota is then tied to IP address alone (same daily cap), which is easier to reset by changing network — signing in gives a stable account-based limit.

Model providers

When you run Generate or Enhance, prompts are sent to configured AI providers (e.g. Anthropic, DeepSeek) according to our product behavior. Those providers process content under their own terms and privacy policies.

Do Not Track

NeuroPrompt does not serve behavioural advertising and does not build cross-site tracking profiles. We honour the spirit of the Do Not Track (DNT) browser signal: no third-party analytics, ad-network pixels, or fingerprinting scripts are loaded. Our Tk: N response header signals non-tracking status on every page.

Local storage & client-side data

NeuroPrompt uses the browser's localStorage to save your in-progress prompt drafts and favourite saved-prompt IDs between page reloads. This data never leaves your device and is not synced to our servers. You can clear it at any time via your browser's developer tools (Application → Local Storage).
