## 2026-11-04 – 1.85.3, the two sandbox keys described apart

Several pages said that nothing is stored under a sandbox key, without telling
the two keys apart. The public sandbox key, `sk_sandbox_public`, keeps a record
of every scan for one year, with a reduced thumbnail and the address it came
from, and that key cannot read, list or delete it. An account's own sandbox
key stores nothing. The integration guides, the first-recognition tutorial and
the tool descriptions now say so, and ask for test images only, never a
real document. [Data retention and
privacy](https://doc.cheap/docs/concepts/data-retention-and-privacy#the-public-sandbox-key-keeps-every-scan-for-a-year)
has the details.
