Security
A summary of the technical measures behind CopyBoard.
Random codes
Board codes are generated using a cryptographic random alphabet with ~40 bits of entropy, formatted as XXXX-XXXX to keep them shareable.
Expiration enforced server-side
The backend refuses to serve boards past their expiresAt timestamp, and a scheduled cleanup purges expired boards and files.
Storage rules
Firebase Security Rules restrict reads and writes to authenticated (anonymous) sessions and validate size limits.
Transport
All traffic is served over HTTPS.
Abuse controls
Rate limits, file type checks and size caps discourage misuse. Content may be removed at any time.
