Privacy Ledger
Your data.
Your ledger.
The Tester Privacy Ledger is a per-device, on-device log of every inference, sync and transmission event. Transparent by default.
On-device
Nothing leaves without your knowledge
Every data event is logged locally before any transmission. The ledger is queryable at any time from the companion app or the watch face.
Minimal collection
We collect what is necessary
Tester collects only what is required to operate the service: device identifiers, firmware versions, and crash logs. Health data never leaves the device.
Your rights
Export, delete, audit
Full GDPR and CCPA compliance. Export your ledger as JSON. Delete all records on demand. Every third-party integration is disclosed and consent-gated.
