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.

      Do not replace failed strength results with passes

      Firms admitted changing failed metal tests to make certificates show a pass. The plea and pause for the parent's case needed court approval and the deal's terms to be met. Separate civil claims stayed disputed; later results were not checked.

      Test cards need to show the real result

      A firm admitted false test cards and misleading follow-up statements in a deal to pause the criminal case. The criminal case could end only if the firm met the deal's terms; it also settled separate civil claims. A charge against an employee was still unproved.

      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 correct testing, accurate results, laboratory competence, product safety, certification, submission or regulatory acceptance.

      It does not establish correct testing, accurate results, laboratory competence, product safety, certification, submission or regulatory acceptance.

      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.
