Terms of Use
This page describes how we operate the service. It is not legal advice about the quotes you send your customers.
RenderSim is a trading name of Bond Labs Limited (company number 17285766). rendersim.co.uk. These terms govern your use of RenderSim (the “Service”). Registered office: 71-75 Shelton Street, Covent Garden, London WC2H 9JQ, United Kingdom. Contact: support@rendersim.co.uk.
The Service
RenderSim helps you prepare and present quotes for External render and Internal plastering. You enter your own rates, customer details and measurements. The Service calculates a quote from those rates, and for External render can paint a chosen finish onto a customer's photograph, and lets you send a customer a link to a frozen copy of the quote. There are no payments in the app: you quote, and the customer pays you. Bond Labs Limited is not a party to any contract between you and your customer.
Your account
Sign-in is by one-time email code. We do not store a password for you. Keep access to your email secure; you are responsible for activity under your account. The Service is for businesses and tradespeople who can enter a contract under the law of England and Wales. You must give an email address you control. We may suspend or close an account that is used to abuse the Service, to break the law, or to attempt to reach another user's data.
Your content
You retain ownership of the quotes, company profile and customer data you add, and any photos you upload on jobs that have a look. You grant us a limited licence to host, display and process that content solely so we can provide the Service (including showing a frozen copy of a quote to someone who holds a link you created). You confirm you have the right to upload any photo and to store your customers' details, and that doing so does not infringe anyone else's rights.
Customer data
You are the data controller for personal data about your customers and clients. We process that data on your behalf so the Service can function. Our Privacy Policy explains what we store and how long share links last. You are responsible for telling your customers what you do with their data, and for handling their requests.
Visualiser images
Images produced by the visualiser are illustrative only. The visualiser is only for External render. They put a colour sample on the customer's photograph, keeping that photograph's light and shade. They are not a photograph of finished work. After a photo lands we look for the house, then the doors and windows on it. If we find them, you can drag a corner that is off; if we cannot, you add them yourself. We never draw an opening we did not see. It is a look, not a survey. It does not invent cracks, damp or substrate (the surface being covered). They are not a specification, a structural assessment, or a guarantee of the finished work, and they are not a photoreal reconstruction of the building. Do not present them as otherwise.
Prices and quotes
Prices are calculated from the rates you enter. You remain responsible for checking every figure, every line and every assumption before a quote goes to a customer. Market-estimate starting rates, if shown, are a starting point only. A quote you send, and any acceptance of it, is a matter between you and your customer.
Customer accept links
A live customer link shows a frozen copy of a sent quote to anyone who holds the address. You can revoke it at any time. A replacement link shows the same saved paper. Issued quotes stay as they were; a change of scope is a new numbered revision. Only a sent quote can be accepted through a link. Tapping Accept records the name typed, the time, and the IP address of the connection as evidence that someone holding the link tapped Accept. That record is evidence of that tap. It is not a certified electronic signature under eIDAS, and we do not claim it is an advanced or qualified electronic signature.
Intellectual property
We own the Service, including the software, design and documentation. You own the quotes, company profile and customer data you add, and any photos you upload on jobs that have a look. You may not copy, scrape or reverse-engineer the Service, or use it to build a competing product.
Acceptable use
Use the Service only for lawful quoting in your trade. Do not upload photos you have no right to use. Do not store other people's data without a lawful basis, and do not attempt to reach another user's account.
No warranty
The Service is provided “as is” and “as available”. We do not warrant that it will be uninterrupted, error-free, or fit for a particular job. To the fullest extent the law of England and Wales allows, we exclude implied warranties. Nothing in these terms excludes or limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot lawfully be limited.
Liability
We are not liable for loss of profit, loss of business, loss of data (except where we fail to take reasonable care of it), or any indirect or consequential loss. Subject to the paragraph above, our total liability to you arising out of or in connection with the Service in any twelve-month period is limited to the greater of one hundred pounds sterling (£100) and the amount you paid us for the Service in that period. The Service does not take payment from your customers, and we are not responsible for whether they pay you.
Changes
We may update these terms and the Service. We will change the “Last updated” date on this page when we do. If a change is material we will try to tell you on sign-in or by email. Continued use after a change means you accept the new terms. If you do not accept them, stop using the Service and delete your account.
Ending the Service / deleting your account
You may stop using the Service at any time. You can download your data and delete your account from Settings. We may withdraw or change the Service, or close an account, where we have a good reason (including misuse, legal risk, or stopping the product). Where we can, we will give reasonable notice. After deletion, share links stop working and we delete the data we hold for the account, except anything the law requires us to keep.
Governing law
These terms are governed by the law of England and Wales. The courts of England and Wales have exclusive jurisdiction, except that we may still apply for interim relief in any jurisdiction.
