05 - FAQ
Good to know.
Do I need an account?
No. Open a board and start creating immediately. Your local board does not require an account.
Where is my work saved?
Your board and imported assets are saved in this browser on this device using local storage designed for larger documents.
Can I annotate PDFs?
Yes. PDFs live directly in the canvas, where you can read, annotate, and connect them to the rest of your work.
What happens if I clear browser data?
Local boards are removed with site data. Cloud backup will be part of Vertexa Plus, not the account-free version.
