About this policy
KROB SlabWorks is a concrete slab planning and estimating application operated by Cash Robinson. This policy explains how the application handles account information and the project information you choose to enter.
Information the application handles
Account information includes your account identifier, email address, and sign-in verification status. If you choose Google sign-in, Google also provides basic profile information, such as your name and profile picture, to the authentication service. If phone sign-in is available and you use it, your phone number is processed to verify your account.
Project information includes project and customer names, job addresses, notes, slab measurements, structure layouts, material specifications, prices, estimates, uploaded plan drawings, extracted geometry and reviews, and saved project timestamps. Only enter customer information you are authorized to use.
The hosting and authentication services may process technical information such as IP addresses, browser information, request times, and error or security logs to operate and protect the service.
How information is used
Information is used to sign you in, associate saved projects with your account, calculate quantities and estimates, restore saved work, produce the exports you request, respond to support requests, and protect the service. The application does not include advertising or marketing tracking features.
Google account data
Google sign-in requests basic identity information: an account identifier, email address, and profile information. It does not request access to Gmail messages, Google Drive files, Google Calendar, or contacts. Google account data is used for account authentication and management, not for advertising or training AI models. The application does not sell Google account data.
Service providers and sharing
Supabase provides account authentication. Google processes Google sign-in when you choose that method. OpenAI Sites and its Cloudflare infrastructure provide application hosting and project storage. Email or SMS delivery providers may process your contact information and verification messages when those sign-in methods are enabled. Each provider also has its own privacy terms.
Project records are associated with your account and are not presented as a public project gallery. PDF estimates and backup files are generated when you request them; you decide whether to download or share them. Service operators and providers may access information as needed for authorized support, service operation, security, or legal obligations.
Optional AI plan reading
When you choose Read with AI, the drawings you selected are sent to the provider named in the upload notice, after you accept that notice. Google Gemini free-tier reading is intended only for drawings without confidential or personal information. Google’s unpaid service uses submitted content and generated results to improve its products, and human reviewers may process that content. Do not send sensitive customer or engineering records through that option. An optional OpenAI API connection requires the owner to enable paid AI explicitly; the application requests response storage to be disabled for that provider, but provider retention policies may still apply. There is no automatic switch from a free service to a paid one. Your Google account credentials and profile are not included in either AI request. Uploads and extracted reviews are stored privately with your account. You can download or delete uploads in AI plan import. Deleting an upload does not remove geometry already imported into a project. The example review uses fixed demonstration data and does not send files to an AI service.
Browser storage and security
The authentication system uses browser storage to maintain your sign-in session. Use Sign out on shared devices. The application uses HTTPS and account-based checks for access to saved projects. No online service can guarantee absolute security.
Retention and your choices
Saved projects remain available until you delete them or request their deletion. You can edit or delete individual projects and export project backups from the workspace. Deleting a project does not delete your account, copies you downloaded, or copies you shared with others.
Contact support to request access, correction, or deletion of account information or other stored information. We may need to verify that the request concerns your account before acting. Hosting and authentication providers may retain backups and security records under their own retention policies and applicable requirements.
You can also remove KROB SlabWorks from your Google Account's third-party connections. Removing Google access does not by itself delete project records or your SlabWorks account.
Policy changes
