Fair draws · LESSON 5
Entrant privacy — we do not collect entrant data
As important as fairness is privacy. Unipicker does not gather entrant data on its servers.
Principle 1
We do not collect entrant data
We do not store entrant personal data like names and contacts on our servers. Even after a draw, Unipicker does not keep who entered.
Principle 2
Uploaded entrant data stays on "your PC"
A list uploaded for a draw is stored only on the PC that ran the draw. It is not sent to Unipicker's servers to accumulate.
Principle 3
We store only what verification needs
All Unipicker keeps is the information essential to verifying the draw.
The hash of the draw materialsWe store only the "digest," not the original list.
The DRAND value usedWe keep the round information used in the draw.
Draw method & result summaryWe record the information needed to verify how it was drawn.
The original list cannot be recovered from a hash. So privacy is protected while tamper verification is still possible. Who won is not recorded by default — it is disclosed, with separate notice, only if the winner-list option is turned on.
In short — entrant data = only on your PC · Unipicker servers = only verification hashes and DRAND. Both fairness and privacy are protected.
