Privacy & data
Your data stays with you
Resume Customizer is a desktop app with no backend of our own. We don't host your data, we don't run accounts, and we don't collect analytics. Here's exactly how your information is handled.
Where your files are stored
Your roles, templates, generated content, and exported PDFs are saved in a folder on your own computer:
- • macOS: ~/Documents/ResumeCustomizer/
- • Windows: %USERPROFILE%\Documents\ResumeCustomizer\
You can change this location in the app's Settings. Deleting an application in the app removes its files from disk.
Your Anthropic API key
The app connects to Claude using your own Anthropic API key. The key is encrypted with Electron safeStorage and saved in the app's private data folder — not in plain text and not in your Documents/ResumeCustomizer folder. It is used only to authenticate requests you initiate to Anthropic.
macOS Keychain prompts
On macOS, safeStorage relies on Keychain to protect the encryption secret. When you first save your API key (or after certain system updates), macOS may ask whether Resume Customizer can access Keychain — choose Allow or Always Allow. The app is not reading your passwords or other apps' secrets; it needs Keychain so your API key stays encrypted on disk between launches.
Step-by-step context is in the documentation.
What is sent to Anthropic
When you generate, score fit with Claude, refine, chat, or build an interview cheat sheet for an application, the relevant content — such as your resume sections, the job description, evaluation feedback, and your instructions — is sent to Anthropic's API to produce a response. This is the only network destination for your document content. Anthropic's handling of that data is governed by your agreement with Anthropic. Review the Anthropic Privacy Policy for details.
ATS parse checks stay local
ATS parseability scoring runs entirely on your computer. The app extracts text from role template PDFs and generated application resume PDFs with local parsers, compares fields (and job-description keywords on application checks), and saves the result with the role or application. Your resume is not uploaded to an ATS vendor, cloud parser, or this website for that check.
Fetching job descriptions
When you paste a job posting URL and choose to fetch it, the app requests that page so it can extract the description, company, and title. That request goes directly from your computer to the job site.
No tracking
The app does not include advertising or third-party analytics, and this website does not set tracking cookies.
