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.

Real cases: why the saved copy matters.

Real cases where dated records mattered. We don’t claim a time receipt would have changed the result.

United States; Eastern District of Wisconsin · 2014

Keep the seal intact until the required check

A driver broke a food shipment's seal before warehouse staff could check it. The customer rejected the load, which sold for less. The court awarded the storage firm its actual loss without finding the food was contaminated.

United States; Eastern District of Wisconsin · 2007

An absent seal alone did not prove damage

A shipper sought full payment for an unsealed butter load, while the carrier disputed its starting condition. The court found facts about condition and salvage still open and refused an early win. The missing seal alone did not prove the food was spoiled.

United States; Fifth Circuit, cross-border shipment · 2013

Customs papers may not prove sealed container contents

Customs forms listed goods before a firm could inspect the containers, and later counts showed shortages. The appeal court removed the shipper's early win because the amount received was still disputed. It did not decide where the goods were lost.

Needs something else · United States; Customs seal standards

19 CFR 24.13a, eCFR current through October 19 2026

Physical seals and fastenings have durability, unique-identification and tamper-evidence specifications; acceptance involves manufacturer attestation and possible test records.

This concerns the seal itself. A timestamp on a photo is neither a seal test nor the manufacturer's attestation.

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 establish origin, identity, truth, physical events, sending, delivery, agreement, acceptance or the outcome of a dispute.

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.

Does a broken seal prove the goods are contaminated?

No. The 2007 decision rejected that automatic inference; the separate 2014 case turned on an actual rejection and value loss.
