Frequently asked questions
What types of sensitive data does this tool detect?
▾
It detects four categories: emails ([email protected] format), phone numbers (7–15 digits with common separators), URLs (http/https), and API keys from known services including OpenAI, Anthropic, Stripe, GitHub, Slack, AWS, Google, and GitLab, plus generic Bearer tokens and hex strings of 32+ characters.
Why wasn't my API key detected?
▾
Detection relies on known prefixes and formats. Keys without a recognized prefix (e.g. a plain UUID used as an API key, or a custom internal token) won't be caught. Always review the sanitized output before sharing — this tool is a helper, not a guarantee.
Is it safe to paste sensitive data here?
▾
Yes. All processing runs entirely in your browser using JavaScript. No text is ever sent to a server, stored, or logged. You can verify this by checking the browser's network tab — there are zero outgoing requests when you type.
Can I turn off specific detection types?
▾
Yes. Use the toggle pills at the top (Emails, Phones, URLs, API Keys) to enable or disable each category individually before sanitizing.
