Sample sync test

This separate test uses generated sample bytes. It cannot open your notebooks, backups, recordings, or drawing files.

Google sign-in requests only this test app’s hidden Drive storage. Nothing is shared publicly. The test leaves one small encrypted sample there; it does not delete files.

Test on a second device

After a passing upload, download its test-key file and transfer it privately. On the second device, import that file before connecting Google. This file contains a temporary key for generated sample bytes only; do not share it publicly.

Import generated sample-key file

Ready. No connection has been made.

Closing or reloading this page clears its temporary keys and access token. This is a Mac-only feasibility test, not notebook synchronization.
