When you create an account we store your email address, display name, phone number, and a hashed password (argon2id, we never store the plaintext). We also store a SHA-256 hash of each resume you upload, the extracted text from that resume, and the analysis results attached to your account.
We do not store the original resume file. The PDF or DOCX you upload is parsed in memory and the binary bytes are discarded the moment text extraction is complete.
