Keep test data in-house.
To test on a cloud device farm, you ship your app build to someone else's servers and your sessions, screenshots and logs are processed there. In HelmSwarm's self-hosted, bring-your-own-device mode, the platform and the devices run on your own infrastructure — so test data never leaves your network.
Does cloud device testing send my data off-site?
Yes. Cloud real-device testing requires uploading app builds, and test sessions/screenshots/logs are handled on the vendor's infrastructure. For regulated or privacy-sensitive teams, that off-site data flow is the problem — not a feature.
How self-hosting changes the picture
In self-hosted / bring-your-own-device mode, both the platform and the real iPhones live inside your environment, connected through a local agent. The practical effects:
- App builds stay in-house. No uploading proprietary binaries to a third party.
- Sessions, screenshots and logs stay on your box. Nothing is processed off-site.
- You are the data controller for the test environment — fewer cross-border transfer questions to answer.
Honest scope: self-hosting removes a class of data-transfer exposure, but compliance depends on your full setup and is ultimately a legal determination — this page is guidance, not legal advice.
Who this is for
Fintech, health, public-sector and EU/TR teams under GDPR or KVKK, and anyone whose security review balks at shipping builds and user-flow data to a third-party cloud.
Your devices. Your data. Your network.
Self-hosted real-device iOS automation — nothing leaves the building.
