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.

Your record, one step at a time.

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 records made at the time matter.

Real cases where dated records mattered. We don’t claim a time receipt would have changed the result.

New Zealand · 2022

A report must say if no visit occurred

An engineer implied a visit in the report but used a seller's photos and an unapproved signature. He was fined and had to train while the work was checked. No intent to misuse the signature or effect on the other case was proved.

New Zealand · 2022

Disclose your interest in the property inspected

An engineer offered his own repaired home for sale, with poor records and little warning of his interest. He admitted the faults and took a rebuke, fine and training. Membership would be suspended only if training was later missed; that had not been shown.

Put temporary advice and follow-up in writing

Advice after digging near a property line was unclear, and a later report did not explain a lasting fix. The review found faults in advice and records, rather than a broad lack of skill. It ordered rebukes, a fine and costs.

Covered condominium and cooperative milestone inspections

2026 Florida Statutes section 553.899(8)–(9)

Covered reports require the professional's seal/signature and specified findings. The association must distribute the prepared summary within 45 days of receiving the report through the specified channels; electronic transmission requires prior consent. File dating proves neither sealing nor delivery.

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 identity, origin, truth, physical state, presence, consent, authority, sending, delivery, acceptance or outcome.

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 dated file prove an engineer visited?

No. The New Zealand driveway case involved misleading inspection implications despite a written report.
