# FAQ

> Frequently asked questions about ProBot - costs, privacy, models, and how it works.

## Is ProBot free?

Yes. ProBot is free to use and MIT-licensed. You only pay your own LLM provider for the tokens your bot uses (often pennies, or nothing on free tiers).

## Do I need a coding background?

No. Building a bot is a guided wizard: upload your resume, pick a model, share the link.

## Which LLMs are supported?

Anthropic (Claude), OpenAI, Azure OpenAI, and Google Gemini. See [Models & keys](/guides/models-and-keys).

## Where is my API key stored?

Kept encrypted with envelope encryption; sent per request, used once server-side, and never logged in plaintext. See [Managed key storage](/guides/managed-key-storage) for the encryption details.

## Will the bot make things up?

No. The bot answers **only** from the knowledge you provide. If something isn't in your resume/bio, it says it doesn't have that information rather than inventing it.

## What data do you collect about recruiters?

Only what they voluntarily submit in the lead form (name, email, company, optional LinkedIn). Conversations are logged anonymously.

## Can recruiters see my LLM key?

Never. The key is envelope-encrypted server-side, decrypted only in memory for one chat request, and never exposed to a visitor.

## Can I run the chat myself?

Yes - you can self-host your bot with the tiny [`probot-bot` runtime](/self-hosted-bot/index) so the chat runs on your own domain, while the dashboard, knowledge, and leads stay on the managed platform.

## How do I delete my data?

Export or delete everything from **Settings → Security & privacy**. Account deletion has a 7-day grace window, then a full purge. See [Export & delete](/guides/account-deletion).
