Your free scavenger hunt record worksheet.
A worksheet, not an official form; use your regulator's / carrier's / insurer's own form where one is required.
- Checkpoint / scan record
- Recorded time / sequence
- Team finish record
Check your regulator's own form. The printable version lists the source behind every field. CSV versions have an instruction row above the headings.
Then date your filled-in copy.
Keep the completed copy and its source records. A time receipt dates those exact bytes; it does not establish that an entry is true or accepted. Save a new copy when the checkpoint record changes.
Your record, one step at a time.
Your photos and files stay on your device, so keep them.
Local preview: files are fingerprinted here. Notes and progress stay in this browser. Keep downloaded copies; browser storage is not a backup.

How to keep notes that hold up
Write notes as soon as you can. Keep the original account rather than replacing it later; the venue decides what weight it gets.
- Write it down straight away, on paper or in the box on a step.
- Put the date, time and place at the top, and who you spoke to.
- Use their words where you can; separate what you saw from what you were told.
- Sign or initial a paper note, photograph it and add the photo.
- Never edit an old note. Add a new dated entry when something changes. A device save time is not independent time evidence or proof of event order.

02 · Date the file’s code
Your device fingerprints the selected file or manifest. Dated follows an independent timestamp; Permanent follows Bitcoin anchoring.
An independent time, tied to the exact bytes.

03 · Keep the evidence
Use the organizer’s own scoring and completion process. Keep its existing completion records.
Keep the originals too. A changed or compressed copy has a different fingerprint.

Proves / Doesn’t prove
Proves
A completed time receipt shows that the exact selected file existed by the independently witnessed time. You can check whether a later copy has the same bytes. It does not establish creation time, authorship, identity, event order, location or the truth of the contents.
Doesn’t prove
It does not prove that a team physically stood at a checkpoint, that nobody shared a clue code, who the players were, or who should win a prize.
This cannot establish physical presence, fair play, unshared clues or who should win.
These are the bounds of a completed proof. The local tester does not establish any time. The chosen court, scheme or regulator decides what to accept.
Questions, answered plainly.
Your file stays on your device. During normal receipt creation, your device sends a randomized code made from its fingerprint, plus encrypted recovery data. It doesn't send the plain fingerprint or the random value that opens the code. Keep the original file and the complete receipt for checking. Privacy Policy.
Can a time receipt prove my team visited every checkpoint?
A completed time receipt shows that the exact selected file existed by the independently witnessed time. You can check whether a later copy has the same bytes. It does not establish creation time, authorship, identity, event order, location or the truth of the contents.
Does my file get uploaded?
Your file stays on your device. During normal receipt creation, your device sends a randomized code made from its fingerprint, plus encrypted recovery data. It doesn't send the plain fingerprint or the random value that opens the code. Keep the original file and the complete receipt for checking.
What should an organizer log at each checkpoint?
Team, leg number, clue code shown, scan time, and who confirmed it. Save the full log as one file when the hunt ends.
Does the order of clues show up on a receipt?
Each receipt dates one file. Each receipt dates its own selected file. Keep the source-system sequence evidence separately; a receipt does not perform or verify the challenge.
Will a receipt settle a dispute over who won?
No. It fixes what the results sheet said at a given time. Who wins depends on your published rules and the organizer.
Can I stop teams from sharing clue codes?
Not with a receipt. Use codes that change per team or time window, and check timestamps for impossible speed.
The file tester runs on your device. It does not issue a timestamp or take a payment.
Keep the records you already have.
Keep your original files and any existing official records while the receipt service is being prepared.
