Legal
Terms of Service
These terms are an agreement between you and the provider of RHACOVA. Please read them before using the service.
Version 1.1 · Last updated October 21, 2026 · Effective October 6, 2026
1. The agreement
RHACOVA is a brand and trade name. RHACOVA is operated by Rafael Heiden, an individual based in Brazil, doing business as RHACOVA (“RHACOVA,” “we,” or “us”). By creating an account or using RHACOVA, you agree to these terms. If you use RHACOVA for a company, you confirm you are authorized to accept these terms for it. Our Privacy Policy explains how we handle information.
2. Accounts and workspaces
You are responsible for your sign-in credentials and for activity in your account. Workspace owners and admins control who is invited, their roles, and the workspace’s subscription. Keep your account information accurate.
3. Free calculators
Our public calculators are free to use without an account. Results are informational and based only on the values you enter.
4. Trials, plans, and billing
- New workspaces start with a 14-day free trial managed by RHACOVA. No credit card is required. A trial workspace may have up to 3 users.
- If the trial ends without a paid plan, the workspace becomes read-only. You can still view and export your existing information, and you can choose a plan at any time to keep creating and editing.
- Paid plans are monthly subscriptions: Solo is $49 per month for 1 user, and Team is $99 per month for up to 3 users. Current plans are shown on our pricing page.
- Subscriptions are billed monthly in advance through Stripe and renew automatically each month until canceled.
- Prices do not include taxes unless stated. You are responsible for any taxes that apply to your purchase.
- If a payment fails, the workspace may become read-only. You can still view and export your data.
- We may change prices with advance notice before your next billing period.
5. Cancellation and refunds
You may cancel your subscription at any time. Workspace owners can cancel through Account & Billing, which opens the Stripe billing portal. Cancellation takes effect at the end of the current paid billing period, and paid access continues until then. Canceling does not remove paid access immediately.
Payments are generally non-refundable. RHACOVA does not generally provide refunds or credits for partial billing periods, unused time, or failure to use the service, except where required by applicable law. Nothing in this section limits any rights you have under applicable law that cannot be waived.

6. Your content
You keep ownership of the information you enter or upload, including your cost data, estimates, proposals, jobs, and your customers’ and suppliers’ details. You give us permission to host, process, and display that content only as needed to provide and support the service. You are responsible for having the right to enter information about your customers, suppliers, and team members.
7. Calculations and business decisions
RHACOVA calculates results from the inputs, settings, and assumptions you provide, using documented formulas described in our methodology. You remain responsible for the accuracy of your inputs, your pricing, the quotes and proposals you send, and your job and contract decisions. RHACOVA does not guarantee any profit, margin, or job outcome.
RHACOVA is software, not professional accounting, tax, legal, engineering, architectural, or financial advice. Consult a qualified professional where appropriate.
8. Shared links
Proposal and quote-request links can be opened by anyone who has them. You are responsible for choosing who receives a link. A customer’s online acceptance records what they accepted; it is not an electronic signature service, and your own contracts govern the work.
9. Acceptable use
- Do not use RHACOVA for unlawful purposes or to store content you have no right to use.
- Do not try to access other workspaces’ data, bypass security or plan limits, or disrupt the service.
- Do not scrape, resell, or reverse engineer the service except as the law allows.
10. Third-party services
RHACOVA relies on third-party services, such as Stripe for payments and Google if you choose Google sign-in. Their own terms apply to your use of them.
11. Changes and availability
We work to keep RHACOVA available and reliable, but we do not guarantee uninterrupted service. We may improve, change, or retire features. We will give reasonable notice of changes that materially reduce a paid plan.
12. Our intellectual property
RHACOVA, its software, design, content, and brand belong to us or our licensors. These terms give you a limited right to use the service; they do not transfer ownership.
13. Ending the agreement
You may stop using RHACOVA at any time. We may suspend or end access for serious or repeated violations of these terms, or where required by law. Before closing an account for reasons other than a violation, we will give you a reasonable opportunity to export your data.
14. Disclaimers
To the extent permitted by law, RHACOVA is provided “as is” and “as available,” without warranties of any kind, whether express or implied, including fitness for a particular purpose.
15. Limitation of liability
To the extent permitted by law, we are not liable for indirect, incidental, special, or consequential damages, or for lost profits, revenue, or data, arising from your use of RHACOVA.
To the maximum extent permitted by applicable law, RHACOVA’s aggregate liability arising out of or relating to the service or these terms will not exceed the amounts you actually paid to RHACOVA for the service during the twelve (12) months immediately preceding the event giving rise to the claim. Nothing in these terms excludes or limits liability where applicable law does not allow it.
16. Governing law and disputes
These terms are governed by the laws of Brazil. Subject to the next sentence, the courts located in Blumenau, Santa Catarina, Brazil, have jurisdiction over disputes arising out of or relating to these terms or RHACOVA. Nothing in this section limits any mandatory jurisdiction, venue, consumer protection, or other rights you may have under the law that applies to you.
17. Changes to these terms
We may update these terms. We will change the version and date above and, for material changes, notify account holders before they take effect. Continuing to use RHACOVA after changes take effect means you accept them.
18. Contact
Support: support@rhacova.com. Legal notices: legal@rhacova.com. Privacy requests: privacy@rhacova.com.
Notices to RHACOVA under these terms may be sent electronically to legal@rhacova.com. We may send notices to the email address associated with your account. This does not replace any method of notice that applicable law requires.
