Terms of Use and Sale
Last updated · 5 June 2026
These terms of use and sale (the “Terms” or “Agreement”) set out the conditions under which REDARROW, a French SARL with share capital of €213,000, registered with the Versailles trade register (RCS) under number 929 483 006, with registered office at 25 Allée de la Fontaine, 78450 Chavenay, France (the “Publisher”, “we”), provides its on-plan measurement service Surplan (the “Service”) and the terms of subscription. They apply to anyone creating an account or using the Service (the “User”, “you”). By creating an account, starting a trial or taking out a subscription, you acknowledge that you have read and unreservedly accepted these Terms. The Service is intended for professionals acting in the course of their business, in particular in construction and public works.
1. Purpose
These Terms set out how the Surplan Service is accessed and used — an online (SaaS) application to import plans (PDF, DWG, DXF, JPG, PNG), calibrate a scale, take measurements (lengths, areas, counts) and export summaries — as well as the financial terms of subscriptions. They prevail over any other document, save for special conditions accepted in writing by the Publisher.
2. Definitions
“Service”: the Surplan application and all its features, accessible online. “Account”: the User's personal space. “Subscription”: the paid plan taken out (Solo or Team), monthly or yearly. “User Content”: the plans, files, measurements and data imported or created by the User. “Team / Workspace”: a shared environment allowing several members to access the same plans.
3. Access and requirements
Accessing the Service requires an Internet connection, a recent browser and a compatible device, the costs of which remain the User's responsibility. Some features (high-definition page rendering, DWG/DXF conversion, annotated PDF export) rely on server-side processing and require an active connection. Legal information about the Publisher is set out in the Legal Notice.
4. Account and credentials
An Account is created with an email and a password. The User undertakes to provide accurate information and keep it up to date. The User is solely responsible for the confidentiality of their credentials and for all activity carried out from their Account, and shall notify the Publisher without delay of any unauthorised use. An Account is strictly personal; shared access is governed by the “Team” features and the number of seats subscribed.
5. Free trial
Every new Account benefits from a fourteen (14) day free trial, with no commitment and no payment card required. At the end of the trial, access to plans and features is suspended until a Subscription is taken out; no charge is made automatically. Data is retained under the conditions set out in the Privacy Policy.
6. Subscription, pricing and payment
Full access to the Service requires a Subscription. The prices in force (for guidance: Solo €19 excl. VAT/month or €190 excl. VAT/year; Team €29 excl. VAT/month or €290 excl. VAT/year, plus €8 excl. VAT/month or €80 excl. VAT/year per additional seat) are shown at the time of subscription. Prices are exclusive of tax; applicable VAT is added under the relevant rules (French VAT, intra-EU reverse charge for businesses with a valid VAT number, or export regime). Payment is processed by our provider Stripe; the Publisher stores no payment card data. The Subscription is payable in advance, by recurring charge according to the chosen frequency.
7. Teams and seats
The Team plan lets you invite members into a shared workspace. The number of billed seats equals the number of members beyond the owner (who is included). Adding a member is billed pro rata immediately; removing a member reduces billing at the next renewal, with no refund for the current period. The Team owner is responsible for paying for all seats.
8. Term, renewal and price changes
The Subscription is concluded for the chosen period (monthly or yearly) and renews by tacit renewal for successive periods of the same length, unless cancelled. The Publisher may change its prices; any change is communicated in advance and applies at the next renewal. Continued use after that date constitutes acceptance of the new prices; failing that, the User may cancel.
9. Cancellation and suspension
The User may cancel their Subscription at any time, free of charge and without penalty, from the billing portal available in “My account”. Cancellation takes effect at the end of the period already paid for, with no pro-rata refund. The Publisher may suspend or terminate access in the event of a breach (notably non-payment, fraudulent or unlawful use), after formal notice has remained without effect where the nature of the breach allows.
10. Right of withdrawal
As the Service is intended for professionals acting in the course of their business, the consumer right of withdrawal (Articles L221-18 et seq. of the French Consumer Code) does not apply. The subscription is firm once payment is validated, subject to the cancellation rights set out above.
11. User obligations and prohibited uses
The User undertakes to use the Service in accordance with these Terms, the law and third-party rights. The following are notably prohibited: importing unlawful content or content for which the User does not hold the rights; any attempt at unauthorised access, disruption or overloading of the Service; reverse engineering, decompiling or extracting the code; reselling, subletting or making the Service available to third parties outside the intended features; sharing credentials beyond the number of subscribed seats. Any breach may lead to suspension of the Account.
12. Intellectual property of the Service
The Service, its software, interfaces, trademarks, logos and databases remain the exclusive property of the Publisher or its licensors. The Subscription grants the User a personal, non-exclusive, non-transferable right of use limited to the term of the Subscription. Nothing in these Terms may be construed as a transfer of intellectual property rights.
13. Your plans and data
The User retains full ownership of their plans, files, measurements and data. The Publisher claims no ownership over User Content and does not use it for any purpose other than providing the Service. The User grants the Publisher a strictly technical and limited licence (to host, process, display, convert and render this content) solely for the purpose of operating the Service. The User warrants that they hold the necessary rights to the plans they import and shall indemnify the Publisher against any third-party claim in this respect.
14. Personal data
The processing of personal data is described in the Privacy Policy, which forms an integral part of the Agreement. The Publisher acts in accordance with Regulation (EU) 2016/679 (GDPR). For data processed on behalf of the User, the Publisher acts as a processor within the meaning of the GDPR.
15. Availability and maintenance
The Publisher uses reasonable efforts to keep the Service accessible, without guaranteeing uninterrupted availability. The Service may be temporarily suspended for maintenance, updates, technical constraints or force majeure. No contractual service level (SLA) is guaranteed unless expressly stipulated separately.
16. Liability and accuracy of measurements
Surplan is a measurement-assistance tool: lengths, areas, counts and quantities are computed from the imported plans and from the calibration (scale) entered by the User. The accuracy of the results depends directly on the quality of the plan, the scale entered and the outlines drawn by the User. Accordingly, the User remains solely responsible for the measurements they produce and for any decisions (quotes, orders, works, estimates) based on them. It is the User's responsibility to check and verify every measurement produced by the software before any use. The Publisher cannot be held liable for any errors, discrepancies, losses or damages resulting from inaccurate measurements, incorrect calibration, a non-compliant plan or the absence of verification by the User. The software is provided “as is”, without warranty as to the accuracy of the results.
17. Limitation of liability and warranties
The Service is provided “as is” and “as available”. The Publisher does not warrant that it will meet all of the User's specific needs or that it will operate without interruption or error. The Publisher's liability can only be engaged in the event of proven fault and only for direct and foreseeable damage. Indirect or immaterial damage is expressly excluded, in particular any loss of business, revenue, margin, market or project, additional construction costs, or harm resulting from an unverified measurement. In any event, and unless a mandatory legal provision provides otherwise, the Publisher's total liability, on any grounds whatsoever, is limited to the amount actually paid by the User during the twelve (12) months preceding the triggering event.
18. Subprocessors and hosting
To provide the Service, the Publisher uses technical providers, notably: Supabase (application hosting and database, European Union), Stripe (payment), CloudConvert (CAD file conversion) and Resend (transactional emails). Data is hosted within the European Union. The detailed list of subprocessors is set out in the Privacy Policy.
19. Force majeure and changes to the Terms
Neither party may be held liable for non-performance due to an event of force majeure within the meaning of Article 1218 of the French Civil Code and French case law. The Publisher may amend these Terms at any time, notably to reflect changes to the Service or to regulations; material changes are brought to the User's attention by an appropriate means. Continued use after they take effect constitutes acceptance; failing that, the User may cancel.
20. Governing law and disputes
These Terms are governed by French law. Before any legal action, the parties shall endeavour to settle their dispute amicably. Failing agreement, and notwithstanding multiple defendants or third-party proceedings, any dispute relating to their validity, interpretation or performance falls within the exclusive jurisdiction of the courts of the place of the Publisher's registered office, save for any mandatory rule of jurisdiction to the contrary. If a provision is held void, the others shall retain full effect.
