help_outlineFrequently Asked Questions

Is Cavren really 100% free without hidden costs?expand_more

Yes, completely free. You can create unlimited resumes, switch through all templates, customize colors and fonts, and export unlimited PDF or DOCX files without ever providing credit card information or subscribing to any tier.

What is BYOK (Bring Your Own Key) and why is it beneficial?expand_more

BYOK allows you to plug in your own API key (such as Gemini, OpenAI, or Anthropic). Instead of paying an arbitrary monthly fee to a third party, your requests go directly from your browser to the AI provider. Often this costs fractions of a penny or falls within standard free API quotas.

Where is my resume and personal information stored?expand_more

All data is saved directly in your browser's local storage and IndexedDB. There is zero server infrastructure capturing your resumes, job histories, or contact details. If you clear browser cache, you can simply restore from a downloaded backup file or your synced Google Drive.

How does the Google Drive backup work without a server?expand_more

Cavren connects client-side directly to Google Drive API using your own client credentials. The tokens and files pass strictly between your browser and Google's official endpoints—Code Entity never sees or handles your credentials.

Can I use Cavren completely offline without an internet connection?expand_more

Yes! Once the application assets are cached by your browser (via service worker), you can open Cavren and edit your resumes, adjust layouts, and draft content without an active internet connection.
