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 original photos matter.
Real cases where dated records mattered. We don’t claim a time receipt would have changed the result.
US · 2013
Online labels do not settle photo ownership
A firm said online copies marked public domain defeated a photographer's ownership. The court disagreed and found copying proved for two works. Other uses still needed a trial, where fair use could apply.

A photo claim can survive an early challenge
A photographer sued over photos posted online, and the site argued the claim was too late. The court let the direct-copying claim go on. Two other claims needed more detail and could be rewritten; no final winner was chosen.

Edited ads do not automatically create shared authorship
A photographer supplied raw images that a client later edited for ads. The court rejected the client's claim of shared authorship but granted some other requests. It did not settle sole ownership of the originals or all claims.

Positions below refer to the cited rule or record type, not endorsement of Timevolt. This service is not represented as an eIDAS qualified timestamp provider. A non-qualified timestamp does not receive the qualified timestamp presumption.
Federal Rules of Evidence 902(14)
Data copied from an electronic device, storage medium or file is self-authenticating if authenticated by a process of digital identification, shown by a certification of a qualified person; the committee note gives hash-value comparison as an example.
The committee note says a hash match shows an original and copy are exact duplicates. It speaks to authenticating copies, not to dating, and a qualified person still has to certify.

Read the source17 USC 410(c)
A certificate of registration made before or within five years after first publication is prima facie evidence of validity and of the facts stated in it; later certificates get discretionary weight.
The law gives evidentiary weight to registration, not to private timestamps. A time receipt does not replace it.

Read the source17 USC 412
No statutory damages or attorney's fees for infringement that began before registration (unpublished works) or after publication and before registration, unless registered within three months of first publication.
Register before infringement or within 3 months of publication to keep these remedies; a dated receipt does not change that.

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 took the photos, where, or that they show what they claim, and it does not decide who wins a dispute; only that the files existed by that date.
This does not establish authorship, truthful content, ownership or copyright registration.
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 time receipt prove I took the photo?

Context for this answerIs the EXIF date enough to prove when a photo was taken?
Not on its own. EXIF can be edited or stripped, so treat it as supporting evidence. A time receipt dated by an independent authority is a separate record of when the file existed.

Context for this answerDo I need to register my photos with the Copyright Office as well?
In the US, usually yes if you want to sue for statutory damages and fees: registration generally must come before the infringement began, or within three months of publication.

Context for this answerShould I get a receipt for the RAW or the exported JPEG?
Both if you can. A receipt covers only the exact bytes you add, so the RAW and each edited export each need their own fingerprint.

Courts decide what evidence they accept. Hash matching is recognized in the federal evidence rules for showing a copy matches an original, but a witness still has to explain it.

Context for this answerIf I edit the photo later, does the receipt still apply?
The receipt covers only the exact bytes you fingerprinted. Any edit makes a different file, so get a new receipt for each version you may need to prove.
