Services operated in-house (no sub-processor)
The following Stalwart Labs Ltd services are operated in-house from infrastructure in the United Kingdom and do not currently rely on a third-party sub-processor for the underlying processing:
- the marketing site, documentation, and blog at stalw.art (served via a content delivery network for static delivery, no personal data of visitors is processed beyond standard server logs);
- the Licensing Portal at license.stalw.art (account, subscription, and invoice management);
- the Support Portal at support.stalw.art (community forum and private priority-support tickets).
