The hard part of a giveaway is not drawing. Any spreadsheet draws. The hard part is that the person who did not win has no way of knowing the draw happened at all — and on a giveaway that works, there is always one who says so in public.
Why a screenshot proves nothing
It is the most common method and it does not survive thirty seconds of thought.
A screenshot shows that a name appeared on your screen. It does not show how many comments were in the list, whether some were removed first, or whether you re-ran the draw until the right name came up. A video of the draw is slightly better — you can see the gesture — but it still does not show what was in the hat.
The problem is not your honesty. The problem is that none of those artefacts lets a third party verify anything.
What the certificate contains
Four things, deliberately few: the post the draw ran on, the date and time, the number of entries kept after your filters were applied, and the winner.
The certificate is readable online by anyone. You publish its link with your announcement; an entrant who doubts opens it and counts for themselves. That is all it needs to do, because that is exactly the question they are asking.
What it does not prove
Worth saying, or the promise is bigger than the product.
The certificate attests to what Lukky read and what Lukky drew. It does not attest that your rules were fair, that the prize exists, or that you contacted the winner. It does not replace a set of rules — the rules generator drafts those.
What it removes is the one accusation you previously had no answer to.
What makes the attestation hold
A certificate is worth what the collection of entries was worth. Lukky is a native app approved by Meta: it signs in through the official Instagram and Facebook authorisation flow, never asks for your password, and reads comments through the official APIs.
A tool that reads a public page from a pasted link attests to what an anonymous visitor could see at that moment. The distinction does not matter until somebody challenges the result, and matters entirely on the day one does.
The certificate is included in every plan, the free one included, which runs one draw a week.
FAQ
- Is the certificate included in the free plan?
- Yes. The free plan runs one draw a week with one winner, and issues the certificate exactly as the Pro plan does.
- Who can read the certificate?
- Anyone with the link. That is the point: your entrants do not have to believe you, they check.
- Does the certificate have legal weight?
- It is evidence of how the winner was selected. It does not replace the giveaway's official rules, which remain the binding document.
- What happens if I run the draw again?
- Each draw produces its own timestamped certificate. Re-running does not overwrite the first one; it creates a second, and both stay readable.
