Questions, answered.
Is OpenShield free?+−
Yes — free to use. The core routing code is gated to trusted maintainers who review it regularly. Your inbox contents never leave your device, and we never sell data. Optional supporter tiers and premium security tools fund the servers.
Is this legal?+−
We never attack spammers. We escalate through official abuse channels first — owner, then registrar, then host. If they are ignored, the community can crowd-fund an escrow pot; verified local law firms bid for the job, and get paid the exact invoice amount only after they submit a court order, registrar suspension, or other verifiable proof of enforcement. Every step is logged in public.
What data do you collect?+−
Only the sender domain and structured metadata from the headers you choose to report (SPF/DKIM/DMARC results, sending IP). Raw headers are parsed and then discarded — your inbox contents never leave your device, and we never sell data.
A domain I own got listed — what now?+−
Claim it and clear it with a one-time DNS TXT record, or dispute it with evidence. Legitimate senders are whitelisted automatically.
How do you stop false or abusive reports?+−
Reporting and voting require a signed-in account and are rate-limited. Every report carries header proof, and the core routing code is gated to trusted maintainers.
Which email apps are supported?+−
Chrome & Edge extensions for Gmail and Outlook web. Yahoo and Firefox are on the roadmap.
