In short: RRR Builder Toolkit works completely offline. We do not collect, store on our servers, share or sell any of your data. Everything you enter stays on your device.
Who we are
This Privacy Policy explains how the Android application RRR Builder Toolkit (package name com.rrrbuilders.toolkit, the “App”) handles information. The App is published by RRR BUILDERS LTD, a company registered in England and Wales (company number 17376515) whose registered office is at 28 Cambridge Road, Hounslow, England, TW4 7BS (“we”, “us”, “our”).
For the purposes of UK and EU data protection law, RRR BUILDERS LTD is the developer of the App. Because the App does not send any information to us, we do not act as a controller of the data you keep in it — it stays under your control on your device.
Summary
- No account or sign-in is required.
- The App does not collect, transmit, sell or share any personal or usage data.
- There is no advertising, analytics, tracking or crash-reporting SDK in the App.
- The App does not request internet access or any runtime permissions (no location, contacts, camera, microphone, photos or files).
- Everything you enter is stored only in the App’s private storage on your device and can be deleted by you at any time.
Information you enter
To calculate estimates, the App processes the values you type in, such as dimensions, quantities, material coverage, waste allowances, prices, labour costs and VAT values.
If you create a project, the App stores its name, type, optional client/reference field and notes. When you save a calculation, the App stores its title, the tool and mode used, your inputs, the main result, the measurement system, any costs and the creation/update dates.
Client or reference details are optional. Please avoid entering personal or confidential information you do not need. If you do enter information about another person (for example a client name), you are responsible for having a lawful basis to keep it.
Storage on your device
Saved projects and calculations are kept in the App’s private local database on your device. Your preferences — measurement system, currency display, default waste and VAT percentages, decimal precision, theme and whether onboarding has been completed — are stored locally as app preferences.
RRR BUILDERS LTD does not receive, and cannot remotely access, any of this information.
No collection or sharing
The App does not send your entries or saved data to us or to any third party. It does not sell data and does not include advertising, tracking, analytics or crash-reporting services. It has no server connection, cloud sync, or in-app sharing/export feature.
Because no user data is collected or shared, the App’s Google Play Data safety section states “No data collected” and “No data shared with third parties”.
Permissions
The App does not request any dangerous or runtime permissions and does not declare the internet permission. It cannot access your location, contacts, camera, microphone, photos, media or files outside its own private storage.
Third-party services
The App contains no third-party SDKs that collect data. The App is distributed through Google Play. When you download or update the App, Google processes information according to its own Privacy Policy. Your device’s operating system (Android) also operates under its manufacturer’s and Google’s privacy terms. We do not receive personal information from these services.
Backups and device security
Android cloud backup is disabled for the App, and its backup rules exclude App data from cloud backup and device-to-device transfer. The App offers no backup or restore service, so deleted data, or data on a lost or replaced device, cannot be recovered through the App.
Please protect access to your device with a screen lock: anyone who can open the App on your device can view its saved projects.
Data retention and deletion
Saved records remain on your device until you remove them. You can:
- Edit project details or remove an individual saved calculation.
- Delete a project together with all of its calculations.
- Use Settings → Delete all saved projects to remove every saved project and calculation (preferences are kept).
- Use Settings → Reset calculator defaults to reset preferences (projects are kept).
- Use Android Settings → Apps → RRR Builder Toolkit → Storage → Clear storage, or uninstall the App, to remove all of its local data.
See Data Usage & Deletion for step-by-step instructions. As we hold no copy of your data, there is nothing for us to delete on our side.
Children
The App is a general-audience tool for construction planning and is not directed at children under 13. The App does not knowingly collect personal information from anyone, including children.
Your rights
Under the UK GDPR, the Data Protection Act 2018 and similar laws you have rights including access, rectification, erasure, restriction, objection and data portability. Because the App does not collect or transmit personal data to us, we hold no App data about you; you can exercise full control over your data directly within the App and your device as described above.
If you have questions, contact us at support@rrrbuilders.site. You also have the right to complain to the UK Information Commissioner’s Office (ico.org.uk).
Security
Data is stored in the App’s private, sandboxed storage, which other apps cannot read under Android’s security model. As no data is transmitted, there is no data in transit to intercept.
Changes to this policy
If a future update changes the App’s features or how it handles data, we will update this policy and the “Last updated” date above before or when the change is released. Significant changes will also be reflected in the App’s in-app privacy page and its Google Play Data safety section.
