Why it matters

One reaction. No proof.

If a client reacts and there's no clear record that you patch-tested them properly, it's your word against theirs — and your insurance, reputation and livelihood on the line. Paper forms get lost. Screenshots aren't enough. Memory doesn't hold up.

PatchProof gives you an unbroken, timestamped record for every client, every time — the proof an insurer actually wants to see.

How it works

Three steps. Two minutes.

No app for your client to download. No forms to file. It just works.

1

Send the test

Pick the client and product. PatchProof captures consent and intake, then sends your client a link — no app to install.

2

They respond at 48h

Automatic reminders nudge your client. They confirm "all clear" or report a reaction with a fresh, verified photo.

3

You're protected

Every result becomes a timestamped record. Reactions are flagged for your sign-off — and your audit PDF is one click away.

Everything included

The whole record, handled.

🕑

Timestamped & photo-verified

Every response is time-stamped, fingerprinted and photo-checked for freshness — tamper-evident by design.

🔔

Automatic 48-hour reminders

Clients are nudged at the right moment, so tests actually get completed without you chasing.

📄

Insurer-ready audit PDF

The exact paper trail your insurer wants — generated in one click, per client or in bulk.

🏥

GP referral letters

If a client reacts, produce a professional GP referral letter instantly, pre-filled and ready to send.

⚑

Risk flags & client history

Prior reactions and allergens surface automatically, so you can make a safe call before every treatment.

🗄

7-year secure retention

Records are kept for seven years in encrypted EU storage, matching UK claim limitation periods.

  • ✓One-click export to the audit trail, GP letter, or full insurer claim bundle.

Questions

Good to know.

Do my clients need to download an app?+
No. Your client simply taps the link you send and responds on their phone in seconds — nothing to install.
Is PatchProof medical advice?+
No. PatchProof is a record-keeping tool, not a medical device. You stay professionally responsible for every clinical decision — PatchProof simply gives you the timestamped evidence and prompts to support it.
Where is my data stored?+
In encrypted EU-region storage (Ireland), aligned with UK GDPR, with records isolated to your account. We never sell or share your data. See our Security and Privacy pages.
What happens if a client reports a reaction?+
The test is flagged "do not proceed" and waits for your acknowledgement. You can record your decision and generate a GP referral letter in one click.
How long are records kept?+
Seven years by default — matching the limitation period for UK personal-injury claims, which is exactly what makes the record useful to your insurer.
Can I cancel anytime?+
Yes. Manage or cancel your subscription whenever you like, and export your records before you go.
