Data Privacy

• All job data is stored locally in your browser using Chrome's storage API
• No data is sent to external servers (except when using the optional LLM analyzer)
• You control your data - export or delete it anytime
• The LLM analyzer sends job descriptions to OpenAI/Anthropic APIs - review their privacy policies

Troubleshooting

Extension not capturing jobs

1. Make sure you're on a LinkedIn job detail page (URL contains /jobs/view/ or /jobs/collections/)
2. Wait for the page to fully load before capturing
3. Check the browser console for error messages

Selectors not working

LinkedIn occasionally updates their page structure. If extraction fails:

1. Open browser DevTools (F12)
2. Inspect the job title/company/description elements
3. Update the selectors in content.js if needed

Storage full

Chrome extensions have storage limits. If you've captured many jobs:

1. Export your data
2. Clear captured jobs
3. Consider deleting jobs you no longer need

LinkedIn DOM Selectors

The extension uses these selectors (may need updates if LinkedIn changes):

Element	Primary Selector
Job Title	.job-details-jobs-unified-top-card__job-title
Company	.job-details-jobs-unified-top-card__company-name
Location	.job-details-jobs-unified-top-card__bullet
Description	.jobs-description__content
