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?

    Record the date, time, place and who you spoke to. New notes are saved separately rather than editing an old note.

      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.

      01 · Keep the exact files

      Keep the original files for pipeline corrosion-protection readings taken at each test point. Include any existing photos, signed records and source-system exports.

      Keep the original files and complete receipt separately, alongside any existing venue, signature and workflow records.

      Keep the originals too. A changed or compressed copy has a different fingerprint.

      Later changes did not fix missing pipeline records

      A firm was fined for gaps in pipeline rust tests and power-unit check records. Later fixes did not undo the past faults. Officials dropped a separate claim about rust inside the pipes and narrowed other findings.

      Check what pipeline readings actually measure

      An agency found faults in how pipeline test readings were used and required new test stations. The firm did not dispute those faults. A fine covered a separate failure to keep records of checks.

      Distinguish pipeline warnings from final findings

      An agency warned about missed pipeline protection checks and missing records. These items brought no suggested fine or order to fix them. Other faults in the same order did lead to required changes.

      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 origin, identity, location, truth, sending, acceptance, compliance or the outcome of a dispute.

      It does not prove origin, identity, location, truth, sending, acceptance, compliance 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.
