Common questions
What counts as a commit?
One call to
dm.commit(). One record sealed. Tool calls committed separately each count as one commit.Is L3 signing available on the free plan?
Yes. L3 non-repudiation with customer-held keys is available on every plan including free. Generate a keypair with
dm.generate_customer_keypair() in Python and register the public key via POST /api/agents/keys. No plan upgrade required. See L3 setup.Can DarkMatter read my commit payloads?
Yes. Payloads are stored in plaintext by default, same as any cloud service. BYOK encryption (Enterprise) lets you encrypt before committing so only you can read the content. The hash chain and signature verification work on the encrypted payload.
What happens if DarkMatter goes down?
Records already committed remain in the database. You can export any record as a proof bundle at any time using the Download button on any proof page or via the API. The proof bundle verifies completely offline with no DarkMatter dependency. The offline verifier is open-source and available at github.com/darkmatter-hub/darkmatter-l3-example.
Can I delete my account?
Yes. Go to Dashboard, Settings and click "Delete account." Type your email address to confirm. Your account and all associated data are deleted automatically within minutes. Any active Stripe subscription is cancelled immediately with no further charges. This action is permanent and cannot be undone.
