Evidence standards

Built to be read by a case manager, an insurer or a tribunal

Photos on a phone prove very little. A TurnProof pack arrives as a business record: produced the same way every time, attributed to a person, fingerprinted so it can be tested, logged step by step, and signed by you.

Every pack includes

Printed and in the PDF
  • Record certificate — how the records were produced
  • The locked reports, with dated and timed photos
  • Costs claimed and the receipts behind them
  • Chain-of-custody log, step by step
  • A declaration ready for your signature

How the records are produced

The part that answers “these could be faked”

Captured in the app only
Photos can only be taken through the TurnProof camera while the report is open. There is no gallery upload, so an older or edited image cannot be substituted in.
Time written by our server
The capture time on every photo and every report is written by our servers in UTC at the moment the file arrives, then displayed in the property's own time zone. A phone clock cannot change it.
Fingerprinted on arrival
Each photo is hashed with SHA-256 as it is stored. The fingerprint is printed with the photo, so any later alteration of the file produces a different fingerprint and is detectable by anyone.
Locked on submission
When a report is submitted it becomes immutable. Lines, counts, notes and photos cannot be edited, replaced or deleted afterwards — enforced by the database, not by app screens.
Attributed to a person
Every report records who submitted it and, where an outsourced crew did the work, the business name and the access link they used. Crews never hold accounts and cannot see other listings.
Retained then released
Photo files are kept for 90 days and then permanently deleted; the report text, times, identities, fingerprints and deletion log are kept. The downloaded pack is the permanent archive.

Set the country on your listing and the pack uses the right wording and the right signature page for that place. Anywhere not listed gets the international form.

Australia

Signed declaration

  • Evidence Act 1995 (Cth) s 69 Business-records exception: records kept in the course of a business, made by someone with personal knowledge, are not excluded by the hearsay rule. Each report in this pack states who made it and when.
  • Evidence Act 1995 (Cth) ss 146–147 Documents produced by a device or process that ordinarily produces accurate results may be presumed accurate. The record certificate describes our capture, timestamp and hashing process for exactly this purpose.
  • Evidence Act 1995 (Cth) ss 48 and 51 Copies and printouts of electronic records may be tendered — there is no original-document rule. This is why the downloaded pack still stands after the photo files are deleted at 90 days.
  • Electronic Transactions Act 1999 (Cth) Electronic records satisfy record-keeping requirements where their integrity is assured. Server-written capture times, fingerprints and locked reports are that assurance.
  • Statutory Declarations Act 1959 (Cth) If the dispute reaches a tribunal or court, this declaration can be made in statutory form under this Act (state equivalents, for example the Oaths Act 1867 (Qld), accept the same form) — the pack wording is already written to convert without rewriting.
  • ISO/IEC 27037 handling practice Identify, collect, preserve and document — the chain-of-custody log in this pack is that documentation, and the SHA-256 fingerprint of each photo lets anyone test that the file was never altered.

Damage claims against a guest are usually heard as a minor civil dispute — QCAT in Queensland, and the equivalent tribunal in each other state and territory.

Signed and dated by the host or co-host — no witness needed. This pack is written to be submitted straight to the booking platform's resolution centre.

  • Contract and Commercial Law Act 2017, Part 4 Electronic records meet record-keeping requirements where their integrity is maintained — which the fingerprints and locked reports demonstrate.
  • Oaths and Declarations Act 1957 If the dispute proceeds to a tribunal or court, this declaration can be made in statutory declaration form under this Act — the pack wording is already written to convert without rewriting.
  • ISO/IEC 27037 handling practice Identify, collect, preserve and document — the chain-of-custody log in this pack is that documentation, and the SHA-256 fingerprint of each photo lets anyone test that the file was never altered.

  • CPR Part 32 and Practice Direction 32 Evidence is given by witness statement with a statement of truth, exhibiting the documents relied on — this pack is formatted to be exhibited.
  • CPR Practice Direction 22 The statement of truth wording in this pack follows this practice direction.
  • ISO/IEC 27037 handling practice Identify, collect, preserve and document — the chain-of-custody log in this pack is that documentation, and the SHA-256 fingerprint of each photo lets anyone test that the file was never altered.

United States

Declaration under penalty of perjury

  • Fed. R. Evid. 803(6) Records of a regularly conducted activity are not excluded by the hearsay rule where made at or near the time by someone with knowledge.
  • Fed. R. Evid. 902(11), 902(13)–(14) Certified business records, certified records generated by an electronic process, and data copies identified by hash value are self-authenticating. The SHA-256 fingerprints in this pack speak directly to 902(14).
  • Fed. R. Evid. 1001–1003 Duplicates and printouts of electronically stored information are admissible as originals.
  • 28 U.S.C. § 1746 The declaration in this pack follows the unsworn declaration wording under this section.
  • ISO/IEC 27037 handling practice Identify, collect, preserve and document — the chain-of-custody log in this pack is that documentation, and the SHA-256 fingerprint of each photo lets anyone test that the file was never altered.

Damage claims against a guest are usually filed in small claims or magistrate court in the property's county.

No notary is required for an unsworn declaration under 28 U.S.C. § 1746; some state courts prefer a notarised affidavit — check your local rules.

Canada

Affidavit

  • Canada Evidence Act s 30 Records made in the usual and ordinary course of business are admissible as evidence of the matters recorded.
  • Canada Evidence Act ss 31.1–31.3 Electronic documents are admissible where the integrity of the recording system is proven — which our server-side timestamps, fingerprints and immutability rule establish.

Swear or affirm in front of a commissioner for oaths or notary public.

International

Signed declaration

  • Machine-produced record integrity Capture times are written by our servers, not the phone, and each photo is fingerprinted on upload — so the record does not depend on trusting a device clock.
  • UNCITRAL Model Law on Electronic Commerce, arts 8–9 The widely adopted basis for treating an electronic record as an original where its integrity is assured and it can be displayed — the standard most national electronic-transactions statutes follow.
  • ISO/IEC 27037 handling practice Identify, collect, preserve and document — the chain-of-custody log in this pack is that documentation, and the SHA-256 fingerprint of each photo lets anyone test that the file was never altered.

Damage claims against a guest are usually heard by the small-claims court or tenancy/consumer tribunal where the property is located.

Signed and dated by the host or co-host — no witness needed. This pack is written to be submitted straight to the booking platform's resolution centre.
