Heatworx

Privacy Policy

Effective date: 15 May 2026

App: Heatworx

Contact: [email protected]

Heatworx is a heat-loss survey and heating design support app for property surveys, room measurements, heating calculations, and related reports. This Privacy Policy explains what information Heatworx collects, how it is used, and what choices you have.

Some features described in this policy may only apply if they are available in your version of Heatworx and you choose to use them.

1. Who we are

Heatworx is operated by TidyGaff Limited. TidyGaff Limited is the data controller for the purposes of UK GDPR.

For privacy questions, data requests, or support, contact [email protected].

2. What Heatworx does

Heatworx helps users capture property and room information, estimate heat loss, review heating system suitability, and generate survey and report outputs.

The app may store survey information such as property details, room dimensions, construction details, heating emitter information, photos, scan-derived room geometry, notes, and calculation results.

3. Data stored on your device

Heatworx is designed to work locally on your device. Survey data is stored on your device, including:

  • Property and survey details
  • Room names, dimensions, areas, volumes, and measurements
  • Surface details such as walls, floors, ceilings, windows, and doors
  • Heating emitter and heat generator information
  • Construction assumptions and calculation inputs
  • Room scan or measurement data
  • Photos or images you choose to add
  • Notes, comments, and report information
  • Calculation results and generated report data

If you delete the app, local data may also be deleted unless it has been exported, backed up, or synced elsewhere by you.

4. Account and subscription data

If you create an account or subscribe, we collect and process account-related information such as:

  • Name
  • Email address
  • Account identifier
  • Subscription status
  • App entitlement level
  • Support requests and related correspondence

Payments and subscriptions are handled by Apple through the App Store. We do not receive or store your payment card details.

5. Survey, property, and customer data

You are responsible for the information you enter into Heatworx.

Depending on how you use the app, survey data may include personal information relating to you, your customers, or properties you survey. This may include property addresses, customer names and contact details, property notes, survey photos, room and building information, heating system information, and generated reports.

If you use Heatworx for work involving your own customers, you are responsible for ensuring you have a lawful basis to collect, store, and share that customer information.

6. Sync, backup, and cloud features

If you enable sync, backup, or cloud features, survey and account data is uploaded to our servers or trusted service providers so that we can provide those features.

Data uploaded for sync or backup may include survey records, room and property information, calculation inputs and results, photos or scan-related data, account and subscription identifiers, and timestamps and change history needed to keep data in sync.

If sync or backup features are not enabled, survey data remains only on your device unless you export or share it yourself.

7. Reports and exports

Heatworx lets you generate, export, save, and share reports. When you export or share a report, you control where that report goes. Reports may contain survey information, property information, customer information, measurements, assumptions, calculations, and recommendations.

You are responsible for checking reports before sharing them with customers, clients, contractors, or third parties.

8. Analytics, diagnostics, and crash reporting

We collect limited diagnostic and performance information to help improve Heatworx, fix bugs, monitor reliability, and understand app usage. This includes:

  • Device model and iOS version
  • App version
  • Crash reports and error logs
  • Performance information
  • Feature usage events
  • Screen or route names at the time of an error
  • General diagnostic information

Diagnostic events are not linked to your identity by default. Where needed to investigate a support issue or crash, we may associate diagnostic data with your account identifier or email address. We do not use diagnostic data for advertising or to track you across other apps or websites.

9. Third-party services

Heatworx uses the following third-party services to operate the app and support users:

  • Apple App Store / StoreKit — subscriptions and purchases
  • Apple device services used by iOS
  • Cloud hosting providers for backend, sync, backup, and account features
  • Sentry — crash reporting and diagnostics
  • Resend — transactional email

Providers may change over time. This list reflects the services in use at the time of the last policy update.

We only share data with third parties where needed to provide the app, support users, process subscriptions, maintain security, or comply with legal obligations.

We do not sell your personal data.

10. How we use information

We use information to:

  • Provide the Heatworx app and its features
  • Store and process surveys
  • Calculate heat-loss and heating-related results
  • Generate reports and exports
  • Manage accounts and subscriptions
  • Provide customer support
  • Fix bugs and improve reliability
  • Monitor app performance
  • Prevent misuse or unauthorised access
  • Comply with legal obligations

11. Legal basis for processing

Where UK GDPR or similar data protection laws apply, we rely on one or more of the following legal bases:

Contract
— to provide the app, account, subscription, sync, support, and related services
Legitimate interests
— to improve the app, maintain security, diagnose issues, and support users
Consent
— where required, such as for optional analytics or permissions
Legal obligation
— where we need to comply with applicable law

12. Data retention

We keep personal data only for as long as needed for the purposes described in this Privacy Policy.

Local survey data remains on your device until you delete it, delete the app, or otherwise remove it.

Account, sync, backup, support, diagnostic, and subscription-related data may be kept for as long as needed to provide the service, resolve issues, meet legal obligations, maintain records, or protect against misuse.

You may request deletion of personal data by contacting us.

13. Your rights

Depending on where you live, you may have rights over your personal data, including the right to:

  • Access personal data we hold about you
  • Correct inaccurate personal data
  • Request deletion of personal data
  • Object to or restrict certain processing
  • Request a copy of your personal data
  • Withdraw consent where processing is based on consent

To make a request, contact [email protected]. We may need to verify your identity before completing a request.

If you are unhappy with how we handle your personal data, please contact us at [email protected] first so we can try to resolve it. You also have the right to complain to the UK Information Commissioner’s Office (ICO).

14. App permissions

Heatworx may request access to device features where needed, such as:

Camera
— for scanning rooms, capturing measurements, or adding photos
Location
— to help identify the survey property location or retrieve local design and weather data. The property latitude and longitude are stored with the survey to support weather lookups and location-based calculations. You can also enter property information manually.
Local storage
— for saving surveys and reports
Network
— for account, sync, subscription, backup, diagnostics, or support features

You can manage app permissions in iOS Settings at any time.

15. Children

Heatworx is intended for professional or adult use. It is not aimed at children. We do not knowingly collect personal data from children.

16. Security

We take reasonable steps to protect personal data against unauthorised access, loss, misuse, alteration, or disclosure.

No app, device, network, or online service can be guaranteed to be completely secure. You should take care when storing, exporting, or sharing survey reports containing customer or property information.

17. International transfers

If we use cloud, diagnostics, support, or hosting providers, personal data may be processed outside the United Kingdom or your country of residence. Where required, we use appropriate safeguards for international data transfers.

18. Changes to this policy

We may update this Privacy Policy from time to time. If we make significant changes, we may notify users through the app, website, App Store listing, or other appropriate means.
