Scope

UK service

Duewise is designed for UK vehicle checks and applies the UK GDPR, Data Protection Act 2018 and PECR. If EU data-protection law applies to a particular user or activity, we will also honour those rights.

Processing record

We collect only the information reasonably required to provide, protect and account for the service.

Purpose: Create, secure and administer your account.

Lawful basis: Performance of our contract and legitimate interests in service security.

Vehicle checks and reports

Purpose: Generate, save and reopen the buyer report you request.

Lawful basis: Performance of our contract.

Lawful basis: Performance of our contract and legal obligations.

Security and abuse prevention

Data: IP address, browser and device signals, security logs, rate-limit events and a one-way device hash used to prevent repeated introductory-check claims.

Lawful basis: Consent where PECR requires it; otherwise applicable legitimate interests subject to your right to object.

AI transparency

How artificial intelligence is used.

Duewise is a decision-support service, not an automated legal, financial, safety or mechanical decision-maker.

Duewise uses server-side AI to help create and structure vehicle knowledge and buyer-report explanations. Outputs may be inaccurate, incomplete or out of date and must be verified against official records, the vehicle, its documents and an appropriate professional inspection. Duewise does not use report output to make a decision producing legal or similarly significant effects about a person. Users can report an error and request human review through support.

Processors

Service providers that may receive data.

Supabase

Authentication, database and storage infrastructure.

Stripe

Checkout, payment processing, invoices and fraud controls.

Vercel

Hosting, content delivery, serverless processing and technical logs.

PostHog

Product analytics only when lawfully enabled and subject to the user's choices.

OpenAI

Server-side assistance with vehicle-knowledge and report content. Do not enter unnecessary personal information in advert text.

Email provider

Verification, password reset, service and support emails.

Providers may process data outside the UK. Where required, Duewise relies on adequacy regulations or approved contractual safeguards and applies data-minimisation and access controls.

Retention

How long we retain data

  • Account, saved vehicle and report data: while the account remains active, then deleted on a valid account-erasure request.
  • Payment and accounting records: up to six years where required for tax, accounting, chargeback or legal claims.
  • Support and security records: normally up to 12 months, longer only where a live dispute, investigation or legal duty requires it.
  • One-way introductory-check device hash: up to 24 months after account deletion for abuse prevention, without the deleted account identifier.
Account deletion

Self-service erasure

Account deletion removes Supabase authentication and account-linked reports, vehicles, wishlist, credits and feedback. A minimal record may be retained where necessary for payments, taxation, fraud, security or legal claims. The right to erasure is not absolute.
