PickKeepersCheck a draw yourself
Paste the proof data from a draw, or your own list and draw code, and your browser works out the result again. If it matches what the room saw, you have checked it.
PickKeepers for iPhone and iPad is coming soon. You can try the free web version now at sviewstudios.com/pickkeepers/app/. Lock-in before the spin, proof links, the QR lobby and the one-device room demo arrive with the next PickKeepers version.
Check a draw yourself
Everything on this page runs in your browser. Nothing you type is uploaded. The code is the same recipe the PickKeepers app uses, copied from the app's source (verify-core.js, from app commit 201c2f1).
The list must be in the same order the app used, with winners who were taken out earlier removed. Spaces and capital letters matter.
Proof links open in the PickKeepers web app, which loads the draw and has its own Check this draw button. This page cannot fetch it for you.
What a pass means
- Result matches: the winners follow from the list and the draw code.
- List was locked in: the list is exactly the one sealed before the spin. A changed, added or removed entry would fail this.
- A pass does not show that the list was complete or honest to begin with. See A raffle everyone can check.
Questions
Does this page upload my list?
No. The check runs entirely in your browser and nothing is sent anywhere.
Where do I get the proof data?
PickKeepers proof links (ending in ?r= and a 12-character code) open a proof page in the web app with its own Check this draw button. The proof data is the same information in JSON form.
Why might a check fail?
The list may have changed after the lock-in, the order may differ, or a name may have a different spelling or capitalization. A failed check means the pieces do not match, and is worth asking the host about.
Is this the same code as the app?
Yes. It is copied from the app source, not rewritten. See the note at the top of the page.
What PickKeepers is not
- Not a scoreboard, game clock, bracket, quiz or flashcard app. For those, see ScoreKeepers (a shared live scoreboard), ClockKeepers (a game clock and timers), BracketKeepers (tournament brackets), QuizKeepers (classroom quizzes), FlashKeepers (flashcards).
- Not a social giveaway tool. It does not log in to Instagram, TikTok or any account, and it does not pull comments. You bring the list, or people join the room.
- Not an account system. Hosts and participants need no sign-up, and the free version has no ads.
- Not a replacement for local raffle or lottery rules. If your raffle needs a license or a reporting step, that part is yours; PickKeepers only makes the draw itself easy to watch and check.
