Now keep it safe: three things
- Keep your photos and files unedited. The receipt only matches the originals. Put them in an album such as “My records”.
- Save this receipt to your camera roll.
Keep the receipt file too. The image is a handy copy; checking needs the file.
- Email it to yourself.Email it to myself
Your mail app opens a draft. Attach your receipt image and receipt file. Don’t attach your photos or documents. Timevolt does not send it or know whether it was sent.

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.

Application within 60 days of catch; photos required (video not accepted in place of photos); certified or legal-for-trade scale; digital photos by email preferred; physical media not accepted.

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 who caught the fish, where or how it was caught, that the scale was accurate, that the fish was not stuffed or swapped, or that IGFA, a state agency or a tournament committee will accept the claim.
This cannot establish who caught a fish, where, scale accuracy, eligibility or acceptance of a record.
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.
What do I need to claim a fish record?
Usually photos of the fish, the scale reading and the angler, a certified scale, and a disinterested witness, filed within a deadline (Texas: 60 days). Check your record body's own form.

Context for this answerDoes a time receipt replace a witness or certified scale?
No. Record bodies require human witnesses and a certified scale. A time receipt only shows the files you lock existed by a date.

Context for this answerWill IGFA or my state accept a time receipt?
Neither rule set we read mentions timestamps or hashes. Attach it as extra support and ask the record body first.

Not always. Texas says video is not accepted in place of photos and does not take photos on thumb drives or discs. Email digital photos.

Context for this answerHow fast do I need to file?
Texas wants the application within 60 days of the catch. Tournaments can be far stricter: one set of rules needs written protests by 9am the next day.

Context for this answerDoes it stop someone cheating at the scale?
No. In a 2022 Ohio tournament, lead weights were found inside walleye by cutting them open. A date on a photo cannot show what is inside a fish.
