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

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.

Screenshots alone may not identify the sender
Prosecutors used chat screenshots, but records from online firms did not link the account to the accused person. The appeal court found too little proof of who sent them. It overturned the guilty finding and ordered a new trial.
Criminal appeal decision; the ruling required a new trial rather than an acquittal.

A profile name does not prove message authorship
Prosecutors offered undated chats and posts from a profile matching the accused person's name, town and school. No witness or other clues showed who wrote them. The court kept the screenshots out.

A message dispute may leave the result unchanged
An accused person offered messages from a witness who said her account had been hacked. The appeal court did not decide if keeping them out was wrong. It kept the guilty result because any such error would not change it.

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 the messages are genuine, who wrote them, that the screenshot matches the real thread on the phone, or that a court will admit them.
A file date does not establish that a conversation happened, who wrote it or that the screenshot is genuine.
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.
Will a time receipt make my screenshots admissible?
No. It shows these exact files existed by the receipt date. Courts still decide authenticity, authorship and hearsay.

Context for this answerHow do I prove a screenshot is real?
Courts usually look for testimony from the person who took it that it accurately shows the conversation, plus sender number, names, dates and content that point to the author. Keep the original phone.

Context for this answerDoes a timestamp stop someone saying my screenshot is fake?
It answers when the file existed, not whether the messages are real. They can still dispute that. Keep the native export and device too.

Context for this answerShould I screenshot the whole thread or just key messages?
Show enough of the thread to include names or numbers and dates. Do not crop, blur or highlight the original; keep a clean copy.

Context for this answerWhy does the template have an Export slot?

What if the other person deletes the messages or says their account was hacked?
That is an authorship dispute a timestamp cannot settle. Courts have weighed hacking claims on other evidence, so keep platform records and device data.
