Key storage test

Checks whether this browser keeps a private key between visits. The key is a throwaway test key; nothing leaves this phone except what you copy.

1. Open this link once in every browser you use: from a Lark chat, in Safari, in Chrome.
2. Fully close the app (swipe it away), open the link again, copy the report.
3. Come back after 1 day, 3 days and 8+ days without opening it in between, and copy the report each time.
