No and this comes up often enough that it's worth being explicit.
Deviera receives webhook metadata only: commit SHAs, branch names, CI check results, PR titles, deployment statuses. It never requests read access to your actual source code.
The only exception is FIXME/TODO scanning and even then, Deviera only sees the diff lines that GitHub sends in the push webhook payload, not the full file contents.
Privacy by design, not as an afterthought.
