Privacy Policy

TestFast is operated by You Know Us Ltd in Scotland, United Kingdom. This policy covers our website, web application and mobile companion app. It explains how we handle account information, electrical inspection reports and information collected when you use our services.

You Know Us Ltd is responsible for the personal information we use to manage accounts, operate our service and communicate with users. Your organisation is responsible for the client and inspection information it enters into TestFast. We process that report information to provide the service to your organisation.

Contact us about privacy at Email TestFast or through https://testfast.uk/contact.

• Account and organisation information: name, email address, account identifier, organisation, role, permissions and team membership. Telephone numbers, addresses and other contact details may be included in your account, organisation or reports.
• Reports and user content: client and site details, inspection and test results, circuit schedules, observations, notes, photographs, signatures, templates and generated certificates or PDFs.
• Usage and device information: pages and features used, interactions, device or browser characteristics, analytics identifiers and session information. Signed-in analytics can be linked to your account, name and organisation.
• Diagnostics: errors, crash information and performance information used to investigate problems. Diagnostic events can include an internal account identifier.
• Communications: information you provide when contacting support or requesting information about TestFast.

People in your organisation may enter client details or other personal information into reports. Only include information you are authorised to use and that is needed for the inspection or certificate.

We use information to authenticate users, manage organisation access, create and synchronise reports, provide offline editing, generate and share PDFs, support users, investigate errors and improve the service. Information in an organisation's reports is available to users who have the relevant access permissions. If you export or share a report, its contents are disclosed to the recipients you choose.

We use account information where necessary to provide the service under our agreement with you or your organisation. We also use information for legitimate interests such as service security, support and product improvement, subject to applicable rights and consent requirements. Where consent is required, including for optional website analytics or affiliate attribution, that is a separate requirement from this policy. We may retain information to meet legal obligations or resolve disputes.

If we send marketing communications, you can unsubscribe or ask us to stop. Essential account and service messages may still be sent.

Camera access lets you photograph faults and distribution boards. Photos you add to reports are uploaded and stored with your organisation's content. Board-photo scanning sends the selected image to our servers for extraction and may involve the AI processing described below.

Bluetooth access supports optional measurement streaming from a compatible test meter. The readings you accept become report data. You can also enter results manually. You can control camera and Bluetooth permissions in your device settings; restricting them affects the corresponding features.

When you use board-photo extraction or AI-assisted observation features, the relevant image, notes or report context is sent to our backend and to Google's Gemini services to produce the requested result. AI output must be reviewed and corrected by the electrician before it is used in a report.

Board-photo processing also retains a copy of the image and extracted board or circuit information in an internal dataset used to improve or train our extraction models. These records can include an internal user identifier. This processing is separate from simply saving a photograph in a report.

AI usage measurements, such as operation type, model, timing and token counts, may be recorded in PostHog and linked to an internal account identifier. This policy does not promise that AI requests are processed only on your device or that every provider immediately deletes request data. Ask us if you need details about the processing arrangements for your organisation.

We use PostHog for product analytics and session replay. It can record interactions and the interface displayed during a session to help us understand usage and investigate problems. Signed-in app analytics can include your internal account identifier, name, organisation and role. Session replay is distinct from recording your camera or microphone. Input masking is configured, but we do not describe all analytics as anonymous.

We use Sentry for crash and error reporting and performance diagnostics. The app associates diagnostic events with an internal account identifier. Its configuration removes request bodies, headers, cookies and URL query parameters from error reports; diagnostic messages may still contain technical context.

The iOS app's analytics and diagnostics help us operate and improve TestFast. Website analytics and referral attribution have separate choices in the website cookie banner.

Our website uses necessary storage to remember your choices. With your analytics choice, PostHog and Ahrefs may process website visits and usage information, including browser and network data. PostHog may also record a session replay with input masking.

With your separate affiliate choice, FirstPromoter records visits from referral links and connects a qualifying sign-up to its referrer. When a referred visitor signs up, the service may receive the new account's email address and user identifier. We use this information to attribute and count referrals.

The companion web and mobile app also uses FirstPromoter to attribute referred sign-ups. When an account is created through a referral, it sends the sign-up email address and, when available, an internal user identifier to FirstPromoter. The website cookie choices control the marketing website, not this separate app.

Optional website scripts load only after the relevant choice is accepted. You can choose analytics and affiliate attribution separately, reject both, or reopen Cookie preferences in the website footer to change your choices.

Our core backend, database, uploaded files and backups are hosted on our own server in Scotland, United Kingdom. We also use external services for specific functions: Google Gemini for selected AI requests, PostHog for analytics, Sentry for diagnostics, Ahrefs for website analytics and FirstPromoter for affiliate attribution. These providers receive the information needed for their function as described in this policy.

We may disclose information where required by law or to address security incidents, protect rights or resolve disputes. Your organisation controls access to its reports, and you control the recipients of reports you share. We do not sell your inspection reports.

Our core service, including report content, uploaded files and backups, runs on our own server in Scotland, United Kingdom. Offline editing also stores working data on your device and synchronises it when a connection is available. Protect devices used for TestFast and manage access within your organisation.

We use account permissions and security controls to protect access. No service or device can be guaranteed completely secure.

Third-party services may process information outside the United Kingdom. The countries and contractual arrangements depend on the provider and the service configuration. Contact us for details about the arrangements relevant to your organisation.

We currently keep account and organisation records, reports, training images, extraction data, analytics and backups without a fixed end date. Individual reports can be removed from the working system by users with the relevant permissions; copies may remain in backups. Organisation records may need to remain available when a team member leaves.

The app does not currently provide a self-service account deletion control. Contact us to request removal of your account or other personal data, including any linked training images. We assess each request against the organisation's records, legal obligations and applicable rights. Removing the app from your device does not remove data stored on our server.

Depending on the circumstances, UK data protection law gives you rights to access your personal information, correct it, request deletion, restrict processing, object to processing and receive portable copies. You can withdraw consent where processing depends on consent; this does not affect earlier processing.

Email Email TestFast to exercise these rights. For information controlled by your employer or contracting organisation, we may need to work with that organisation. We may ask for information to verify your identity. We normally respond within one month and will explain if a permitted extension or exception applies.

You can complain to the Information Commissioner's Office at https://ico.org.uk if you are unhappy with how your information is handled.

We update this policy when the service or our practices change. The date above identifies the latest version. Material changes affecting users may also be communicated through the app or by email.
