Is an online clipboard safe?
Short answer: it depends on the service. Here is exactly what CopyBoard does, and does not do, with your data.
What we store
Only what you drop on a board — text, images, videos, and files — plus the position of each card and a creation timestamp. No account, no name, no email, no IP tracking for tracking's sake.
Who can see your board
Only the people you give the 8-character code or QR link to. Codes are random with roughly 40 bits of entropy — practically unguessable. Search engines never index them.
How boards are protected on the server
Firestore security rules refuse to serve a board past its 24-hour expiration. File-storage rules cap size and require an authenticated session token. All traffic runs over HTTPS.
When your data is deleted
Exactly 24 hours after creation the board becomes inaccessible. A cleanup process removes the actual files from storage and the metadata from the database.
What we do NOT do
No advertising. No selling of data. No tracking cookies for other services. No permanent copies. No account requirement.
Threat model — what to be careful about
Because anyone with the code can open the board, treat the code like a temporary password. Do not paste it into public places. If you upload something sensitive, remember that anyone who happened to know the URL before it expired could still have viewed it.
