Terms of service
Last updated: November 12, 2026
These terms are an agreement between you and Leandro Melchor Cordero Davila, who runs Obrarum, with an address for notices at Paseo Revolución 10, Panorama, 76904 El Pueblito, Querétaro, Mexico (“Obrarum”, “we”, “us”). They set the rules for using the Obrarum website and app. By creating an account, you accept these terms and confirm that you have read our privacy policy. If you don't agree with them, don't use Obrarum.
Who can use Obrarum
Obrarum is intended for business and professional use. By creating an account, you confirm that you use it as part of your business or profession. To use it, you must be at least 18 years old. If you create an account for a company, you confirm that you are authorized to accept these terms on its behalf, and “you” means that company too.
Obrarum is a tool
Obrarum is software for preparing and sharing estimates. We don't take part in your work, your prices or your agreements with your clients, and we don't review what you enter or send. You decide how to use Obrarum and you are responsible for the results.
Your account and your team
- Give us accurate information when you sign up and keep it up to date.
- Keep your password safe. You are responsible for what happens in your account, so tell us right away if you think someone else has accessed it.
- Each account is for one person. Don't share your sign-in with others: invite them to your team instead.
- The owner of a business in Obrarum decides who joins its team and what each member can do. Members can see and edit the business's data according to their role.
- A team's content belongs to the business, not to the member who entered it. A member who leaves or is removed loses access to it.
Plans and payments
- Free plan. You can use Obrarum for free in your personal workspace, with the limits shown on the pricing page. Teams need a paid plan.
- Paid plans. Pro and Business are monthly subscriptions. Prices are shown and charged in your local currency where we support it, otherwise in US dollars; you see the currency before you pay. Our payment provider adds the applicable taxes at checkout.
- Extra users. Extra users are billed monthly with your plan. If you add or remove users or change plan during a period, our payment provider calculates and charges or credits the difference under its own terms.
- Payment provider. Payments are processed by Polar, which sells you the subscription and charges you. When you pay, you also accept its terms for buyers. You can download your invoices from the Subscription section in Obrarum.
- Invoices. Our payment provider issues your invoices, with the tax breakdown, and you can add your tax details to them. They are not the electronic tax invoices that your country's tax authority may require (for example, the CFDI in Mexico or the factura electrónica in Peru). Whether you can deduct them depends on your country's tax rules, so check with your accountant.
- Automatic renewal. Your subscription renews every month and is charged to your payment method until you cancel it.
- Cancellation. You can cancel or change your plan at any time from the Subscription section in Obrarum. If you cancel, you keep your plan until the end of the period you paid for, and then your subscription ends (see “When a subscription ends”).
- Refunds. We don't refund payments, including periods you have already paid for, unless the law requires it. Our payment provider may issue refunds under its own rules, for example to prevent a payment dispute, and in that case your subscription is canceled.
- Failed payments. If a payment fails, your plan keeps working while our payment provider retries the charge. If the payment can't be completed, your subscription ends (see “When a subscription ends”).
- Disputed payments. If a payment is disputed, we may suspend your account.
- When a subscription ends. Nothing you created is deleted. Your personal workspace moves to Free: everything stays available, but projects beyond the Free limits are locked for editing, and you can't create anything that exceeds those limits. A team workspace keeps all its data but becomes read-only until it subscribes to a paid plan again.
- Price changes. If we change the price of your plan, we will tell you at least 30 days before. The new price applies from your next billing period, and you can cancel before then.
Your content
Your projects, estimates, quotes, library, client details and files are yours. You give us permission to store, process, display and copy them only as needed to provide the service to you and to measure and improve Obrarum, for example to show them to your team, generate your exports or run Obrarum AI. This permission ends when your content is deleted.
You are responsible for what you enter in Obrarum, in particular the data you store about your clients and having the right to store it. You confirm that you collect and use it in line with the law, including informing them when the law requires it. We don't review that data.
With your clients' data, we commit to:
- Use it only to provide the service to you and to measure and improve Obrarum, as our privacy policy explains.
- Keep it secure and confidential.
- Delete it when you delete it.
We use the providers listed in our privacy policy, which also explains our role with that data. If a security breach affects that data, we will tell you.
Sharing quotes and client approval
When you share a quote, Obrarum creates a link and a 6-digit access code. Anyone with both can view the quote and respond to it, so you decide who receives them. You can revoke a link as long as the client hasn't responded. If you set a validity period for your quotes, the link expires when it ends; otherwise it doesn't expire. An answered quote stays visible to anyone with the link and the code.
When your client approves a quote, Obrarum records their name, ID number, drawn signature, the date, their IP address and the approximate location it points to, and the browser and device they used. This record shows that the client approved that quote. It is not an advanced or certified electronic signature: we don't verify the signer's identity, and we don't guarantee that the record has a specific legal value in any country. You are responsible for confirming the signer's identity and that they have authority to commit your client. You decide whether the record is enough for your work, and when it isn't, you can use a formal contract as well.
If you delete the project (after the 30 days in which you can restore it), close your account or delete the team, the approval record is deleted too. Download the PDF certificate if you need to keep it.
Obrarum isn't a party to any agreement between you and your clients (see “Obrarum is a tool”). You are solely responsible for your quotes, prices, the work you carry out, the payments between you and your clients, and any claims or disputes between you.
If you received a quote
You don't need an account to view a quote or respond to it. Obrarum only displays it: the business that sent it to you is responsible for its content, prices and the work. Questions and claims about the quote go to that business. By entering the access code, you accept these terms, including the “No warranties” and “Limitation of liability” sections.
Obrarum AI and the Obrarum library
Obrarum AI suggests and reviews items, quantities and chapters automatically. Its suggestions can be wrong or incomplete, and we don't verify them. The Obrarum library is a reference with components and quantities, without prices, and may not fit every job or market.
Before you send a quote, review every item, quantity, price and total. You are responsible for the final content of your quotes, whether or not you used Obrarum AI or the library to build them.
What you can't do
When using Obrarum, don't:
- Break the law or help others break it, or use Obrarum to deceive or defraud anyone.
- Enter personal data you don't have the right to use.
- Upload content that infringes other people's rights or contains malicious code.
- Try to access accounts, data or parts of the service that aren't yours.
- Interfere with the service, overload it, or get around its security or plan limits.
- Copy, decompile or reverse engineer the software, or extract the Obrarum library or other content in bulk.
- Access the service in an automated way, for example with bots or scraping.
- Resell or sublicense access to Obrarum without our written permission.
Our property
The software, the design, the Obrarum name and logo, and the Obrarum library belong to us. While you have an account, we give you a limited, non-exclusive and non-transferable right, for you and your team, to use them through the service. If you send us ideas or feedback, we can use them freely, without any obligation to you.
Changes to the service
Obrarum is growing, and we may add, change or remove features. If we remove a feature that is part of the plan you pay for, we will tell you in advance. We work to keep Obrarum available and its calculations correct, but we can't guarantee that it will always work without interruptions or errors. Export the documents you need to keep.
We may change the Free plan limits with 30 days' notice.
If we discontinue Obrarum, we will give you 30 days' notice. During that time we won't make new charges, and you can export your data until the end. We don't refund the current period.
Events outside our control, such as outages of the providers Obrarum depends on, can affect the service and are not our responsibility.
Suspension and closing your account
You can stop using Obrarum and delete your account at any time from your account settings. This deletes your personal workspace and every team where you are the only member, and ends their subscriptions immediately, without a refund for the rest of the period. A team with other members passes to its longest-standing admin or, if there is none, to its longest-standing member, and its subscription ends when the period you paid for ends. A team's owner can also delete it from the team page when no one else is in it.
We may suspend or close your account if you seriously or repeatedly break these terms, if you use Obrarum in a way that puts other users, the service or us at risk, or if the law requires it. Unless the law or the risk prevents it, we will tell you first and give you time to export your data.
When an account is closed, we delete its data as explained in our privacy policy.
No warranties
We provide Obrarum “as is” and “as available”. As far as the law allows, we don't make any promises beyond those written in these terms, including that the service will fit your specific needs.
Limitation of liability
As far as the law allows:
- We are not liable for indirect or consequential damages, such as lost profits or lost contracts or jobs.
- We are not liable for the content of quotes, for decisions you make from them, or for lost data.
- Our total liability for any claim related to Obrarum is limited to the amount you paid us in the 12 months before the claim, or 100 US dollars if you didn't pay anything.
If your client, or a person whose data you entered, makes a claim against us because of your quotes, work or content, you cover the costs it causes us.
Nothing in these terms limits liability that the law doesn't allow to be limited, such as for fraud or intentional misconduct, or the rights that consumer protection laws give you.
Changes to these terms
We may update these terms. Minor changes take effect when we publish them. If a change is important, we will tell you by email or with a notice in the app at least 30 days before it takes effect. If you keep using Obrarum after that date, you accept the new terms. If you don't agree with them, you can cancel your plan and close your account.
Governing law and disputes
These terms are governed by the applicable federal laws of Mexico. If you have a problem with Obrarum, write to us first and we will try to solve it together. If we can't, you and we submit to the competent courts of the city of Santiago de Querétaro, Querétaro, and waive any other jurisdiction that might apply, unless the law gives you the right to go to the courts or authorities of the place where you live.
General
- These terms are the entire agreement between you and us about Obrarum.
- If a part of these terms is found invalid, the rest stays in effect.
- If we don't enforce a right at some point, we don't give it up.
- You can't transfer your account or these terms to someone else without our permission. We may transfer them to a company we create to run Obrarum, or to whoever acquires it, and we will tell you if that happens.
- The property, warranty, liability and dispute sections continue to apply after your account is closed.
- These terms are available in Spanish and English. If the two versions differ, the Spanish version prevails.
