Privacy

Your PDF is read in memory on our server to extract its text and check it for hidden content. It is never written to disk, file storage, our database or our logs, and it's discarded when the analysis finishes.

To produce the feedback, the resume text (and the job description, if you add one) is sent to Anthropic's Claude API, which processes it in the United States. Anthropic doesn't use API data to train its models and keeps it only for a limited period under its commercial terms. See Anthropic's privacy policy.

For each analysis we store one anonymised record containing only:

• broad categories chosen from fixed lists: role type, seniority, industry and a years-of-experience band;
• the page count, the scores, and whether a job description was used;
• whether hidden text or AI-directed instructions were found;
• the models used, token counts, cost and how long the analysis took.

We don't store your name, contact details, employers, schools, the resume text or the job description, and the record can't be linked back to you. We use these stats to improve the scoring and to keep the tool within its running budget.

To keep the tool free, each visitor can run a limited number of analyses a day. To enforce this we keep a one-way, salted hash of your IP address for up to 24 hours. We never store your IP address itself.

We don't use tracking or advertising cookies. Your light/dark theme choice is saved in your browser's local storage and never sent to us.

Resume Optimiser is a personal, non-commercial project built by toninmotion. If you have a question about your data, get in touch through the portfolio site.
