Now keep it safe: three things
  1. Keep your photos and files unedited. The receipt only matches the originals. Put them in an album such as “My records”.
  2. Save this receipt to your camera roll.

    Keep the receipt file too. The image is a handy copy; checking needs the file.

  3. 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.

          1. Write it down straight away, on paper or in the box on a step.
          2. Put the date, time and place at the top, and who you spoke to.
          3. Use their words where you can; separate what you saw from what you were told.
          4. Sign or initial a paper note, photograph it and add the photo.
          5. 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.

          Keep sale terms and damage disclosure together

          A private car buyer said earlier damage had not been disclosed. The court believed the seller, and old auction photos did not prove deceit. It applied the as-is sale terms and ruled for the seller after trial.

          An ordinary bill of sale is not needed for title transfer only when all title information is complete; other stated circumstances require it. The secure odometer form has a separate role. A fingerprint performs none of the transfer requirements.

          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 true condition, correct mileage, disclosure, payment, ownership transfer or an enforceable warranty.

          It does not establish true condition, correct mileage, disclosure, payment, ownership transfer or an enforceable warranty.

          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.
