FAQ

Short answers about using StackHangar: what it can see, passkeys, playbooks, agents, browsers and what happens if you stop paying.

#Can StackHangar see my API keys or passwords?

No. They are encrypted in your browser with a key that only your passkeys can unlock. StackHangar's servers store encrypted data plus an opaque ID and date for each alert. It never receives your secrets, your item names or your project names in plain text. See What StackHangar can see.

#How is this different from my password manager?

Password managers store logins. StackHangar organizes everything a product depends on, including API keys, domains, certificates and subscriptions, by project and environment, then alerts you before any of it expires or needs rotating. Many founders keep both, and you can import from your password manager to get started.

#What happens if I lose my passkeys?

You set up at least two passkeys and a printable recovery key at signup. Any one of them unlocks your vault. Because StackHangar cannot decrypt your data, it cannot recover it if you lose all of them. See Troubleshooting and Recovery key.

#What is a playbook?

A step-by-step fix attached to a project: rotate a key, respond to a leak, or shut a product down. Fixed rules decide the steps. AI can explain a step, but it never adds or skips one. See Playbooks.

#Does it rotate keys or renew domains for me?

It walks you through it. A playbook lists every step and sends you to the right provider account. On Solo it can also send the new key to Vercel, GitHub or Netlify and redeploy, straight from your browser, so the value never reaches StackHangar's servers. Nothing changes in your accounts without your approval. See Deploy targets.

#How do AI agents connect?

Through the MCP server. Each agent signs in with its own identity, so you can see and revoke what it has done. An agent can ask you to paste a new key in your browser, request access to one, or propose a playbook, like rotating a key. You review and approve each one in your browser. It only ever receives reference IDs and your approve or deny answer, never a value. See Connect an agent.

#Which browsers work?

Any recent browser with full passkey support, including current versions of Chrome, Safari and Edge. If your device does not support the passkey features StackHangar needs, it tells you at signup which browser to use. The browser extension works in Chrome, Edge, Brave and Arc on a computer.

#What if I stop paying?

Nothing is locked away. You can still unlock your vault, view everything and export it at any time. The Free limits apply again: 2 projects (the ones you have stay), 1 connected agent, and no sending from your browser. See Plans.

#How much does it cost?

Free is $0 and includes 2 projects. Solo is $99 a year ($8.25 a month) or $12 a month and removes the project and agent limits. It is priced per project, never per key. See Plans.

#Can I export my data?

Yes, on any plan, even if a subscription has ended. See Export your vault.

No. For your company's legal details you copy each field yourself from the Business page. See Business profile.
