How?
Use the exact existing record from your system. A file date does not verify its contents or the action it describes.
Add link and screenshots
The link is recorded, not fetched or verified.
Keep the exact population your auditor sampled. Export the population and its report parameters. Save the row count and per-row digest file if your source system produces them.
Your photos and files stay on your device, so keep them.
Keep the receipt file too. The image is a handy copy; checking needs the file.
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 photos and files stay on your device, so keep them.

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

Write notes as soon as you can. Keep the original account rather than replacing it later; the venue decides what weight it gets.
Export the population and its report parameters. Save the row count and per-row digest file if your source system produces them.
Use the source system’s own record.
Your device fingerprints the selected file or manifest. Dated follows an independent timestamp; Permanent follows Bitcoin anchoring.
An independent time, tied to the exact bytes.
Keep the exact export alongside the sample selection and the source system’s own row identifiers.
Keep the originals too. A changed or compressed copy has a different fingerprint.

Positions below refer to the cited rule or record type, not endorsement of Timevolt. This service is not represented as an eIDAS qualified timestamp provider. A non-qualified timestamp does not receive the qualified timestamp presumption.
17 CFR 210.2-06 Retention of audit and review records
Requires auditors to keep workpapers (procedures, evidence, conclusions) for seven years after the audit and to keep records that conflict with conclusions. Says nothing about independent timestamps for client-produced lists.

Penalizes knowingly altering or falsifying a record with intent to impede a matter, up to 20 years. It is the stake behind a later-edited population, but it does not mention timestamps.

Read the sourceA 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.
It does not prove the report query was right, that the list was complete or accurate against the source system, who ran it, or that an auditor will accept it.
The receipt cannot show the population was complete, the query was right, or an auditor accepted the sample.
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.
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.
We cannot say. A receipt shows the exact file existed by a given time; the auditor still decides what evidence they need and tests completeness and accuracy themselves. Ask them first.

Seal the query or report settings, the export file, the row count, and the sample draw (seed and selected rows). Each is its own file with its own receipt.
Seal the new run as a separate receipt and keep the old one. Two receipts with different fingerprints show that the list changed between runs, which you should explain rather than hide.
A locked folder shows your policy, but the date is your own system's clock. A time receipt adds a date from an independent authority.
For auditors of US-listed issuers, seven years after the audit under SEC rule 17 CFR 210.2-06. Your own policy may differ.

Context for this answerThe file tester runs on your device. It does not issue a timestamp or take a payment.
Keep your original files and any existing official records while the receipt service is being prepared.
