In short

  • You keep ownership of your documents. We host them only to run inSigner for you.
  • Mandatory consumer rights in your country always apply, wherever you live.
  • You can export your data and leave at any time. We give you 30 days after closure to download it.
  • Liability is capped at the fees paid in the last 12 months, except where the law does not allow a cap.

01The agreement

These terms are a contract between you and Nubesti LLC, a Delaware limited liability company (“Nubesti”, “we”, “us”), for the inSigner service. They cover insigner.co, the workspace at app.insigner.co, signing pages at sign.insigner.co, the API, the add-ons, and the iOS and Android apps once they are released.

If you accept these terms for an organization, you confirm that you are authorized to bind it, and “you” means that organization. If a signed order form or Enterprise agreement conflicts with these terms, the signed document controls for that plan. For business customers, the data processing agreement is part of these terms.

02Definitions

Some words have a specific meaning in these terms:

  • Customer: the person or organization that holds the workspace and the subscription.
  • User: a person the customer allows to use the workspace, such as a teammate.
  • Signer: a person invited to view, approve, or sign a document through a link.
  • Customer content: documents, fields, templates, signer details, and other material you or your users upload or create.
  • Add-ons: optional features that are priced separately, such as OTP by WhatsApp and SMS, document signing on WhatsApp, and KYC identity verification.
  • Consumer: a person acting for purposes outside their trade, business, craft, or profession.

03Who can use inSigner

You must be at least 18 years old, or the age of majority where you live if it is higher, to open an account. You may not use inSigner if you are subject to sanctions administered by the United States, the European Union, the United Kingdom, or the United Nations, or if you are located in a country or region under a comprehensive embargo.

Signers do not need an account. A signer who opens a link accepts these terms only to the extent they concern the signing page, the acceptable use policy, and the privacy policy.

04The service

inSigner is a managed cloud service for preparing documents, inviting people to sign, and keeping an evidence record of what happened, including a hash of the file and a history of events. inSigner does not decide whether a signature has a particular legal effect. The electronic signature responsibilities page explains that limit.

We may improve, change, or retire features. If we remove a feature that is material to a paid plan, we will tell the account email at least 30 days in advance, unless a security or legal reason requires a faster change. Beta or preview features are marked as such, may change without notice, and are provided without any service commitment.

We work to keep inSigner available, but we do not promise a specific uptime percentage unless an Enterprise agreement says so.

05Accounts and security

Give us accurate account information and keep it current. Keep your credentials private, turn on the strongest sign-in option we offer, and tell us at [email protected] as soon as you believe an account is compromised. You are responsible for activity in your workspace until you tell us that access is no longer safe.

Workspace administrators can invite and remove users, and can see the documents that belong to the workspace. You are responsible for choosing who has access.

06Your content

You keep all rights in customer content. You give Nubesti a worldwide, non-exclusive, royalty-free permission to host, copy, process, transmit, and display customer content only as needed to provide inSigner, keep the signature record, prevent abuse, and comply with the law. This permission ends when the content is deleted, except for records we must keep as described in the data deletion policy.

You are responsible for customer content, for having the right and the legal basis to upload it and to send it to the people you invite, and for the instructions you give us. We do not review documents before they are sent, and we do not use customer content to train artificial intelligence models or for advertising.

07Add-ons

Add-ons are available on every plan and are priced separately. When you turn one on, you also agree to the following:

  • OTP by WhatsApp and SMS, and document signing on WhatsApp: you confirm that each recipient expects the message and that you have any consent the law requires, including under the U.S. Telephone Consumer Protection Act and local telecom rules. Messages must follow the WhatsApp Business Messaging Policy and carrier rules. Delivery depends on carriers and on Meta, and is not guaranteed.
  • KYC identity verification: you decide when verification is needed, and you give signers the notice the law requires. The identity verification page explains how Didit processes identity documents and biometric data, and how long results are kept.
  • A verification or message result is evidence that a check ran. It is not a guarantee of identity, and it does not by itself satisfy an anti-money-laundering or know-your-customer obligation that applies to your business.

08The API and integrations

API keys are confidential and belong to the workspace. Use the API within the documented limits, do not share keys publicly, and do not use the API to scrape, overload, or reverse engineer the service. We may throttle or rotate a key that puts the service or other customers at risk.

If you connect inSigner to a third-party service, that service’s terms and privacy practices govern what it does with the data you send to it.

09Plans and payment

Essential and Pro are monthly subscriptions with a one-month trial. The listed price applies after the trial unless you cancel before it ends. PayPal processes payments, and inSigner does not store your card number. Enterprise terms are agreed separately. The billing policy and the refund policy form part of these terms.

10Confidentiality

Each party will protect the other’s non-public information with at least reasonable care and use it only to perform this agreement. This does not cover information that is already public, independently developed, or lawfully received from someone else. Either party may disclose information when the law requires it, after giving the other party notice where that is allowed.

11Data protection

The privacy policy explains how Nubesti handles personal data as a controller. For personal data inside customer content, Nubesti acts as a processor or service provider under the data processing agreement, which includes the EU Standard Contractual Clauses and the other transfer terms described there.

12Our property and feedback

Nubesti owns inSigner, its software, its designs, and its brand. These terms give you a limited, non-transferable right to use the service during your subscription. They do not license the software for you to host, copy, or resell. You may not remove our notices, or use the service to build a competing product.

If you send us feedback, we may use it without any obligation to you.

13Suspension, termination, and export

You can stop using inSigner and close your workspace at any time. We may suspend access, with notice where practical, if an account breaks these terms or the acceptable use policy, creates a security risk, or has an unpaid balance, or if the law requires it. We will limit a suspension to what the problem requires and restore access once it is solved.

After a workspace closes, you have 30 days to download documents and signature records, unless we closed it because of a serious breach or a legal order. After that period, we delete customer content as described in the data deletion policy.

Where the EU Data Act applies to you, you can ask to switch to another provider or to your own systems. We will help you export your exportable data in a structured, commonly used, machine-readable format, and we will not charge switching fees beyond what that regulation allows.

14Warranties and disclaimers

We will provide inSigner with reasonable skill and care. Except for that commitment and the rights the law gives you, the service is provided “as is” and “as available”. To the extent the law allows, Nubesti disclaims implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that a signature will be enforceable, that the service will be uninterrupted or error-free, or that it meets a certification we have not stated. We do not provide legal advice.

15Limitation of liability

To the extent the law allows, neither party is liable for lost profits, lost revenue, loss of goodwill, or indirect, special, or consequential damages. Each party’s total liability arising from the service is limited to the greater of the fees paid for inSigner in the 12 months before the claim or 100 US dollars.

These limits do not apply to fraud, to death or personal injury caused by negligence, to a customer’s payment obligations, to a breach of the acceptable use policy, or to any liability that the law does not allow a contract to limit or exclude. If you are a consumer, these limits do not reduce your statutory rights.

16Indemnity

If you are a business customer, you will defend and indemnify Nubesti against third-party claims that arise from customer content, from messages or verifications you requested without a lawful basis, or from your breach of the acceptable use policy. We will tell you promptly about the claim, let you control the defense, and cooperate reasonably. This section does not apply to consumers.

17Consumers

If you are a consumer, nothing in these terms limits the rights that the consumer law of your country of residence gives you and that cannot be waived by contract. This includes rights in the European Union, the United Kingdom, Switzerland, Latin America, and other regions, such as withdrawal rights, legal guarantees, and the right to bring a claim before the courts of your home country. The refund policy explains the withdrawal periods we honor.

18Governing law and disputes

Before starting a formal claim, write to [email protected] with a description of the problem. Both parties will try in good faith to resolve it within 30 days.

These terms are governed by the laws of the State of Delaware and the federal laws of the United States, without regard to conflict-of-law rules. The state and federal courts located in Delaware have jurisdiction over disputes with business customers. If you are a consumer, you may also bring a claim in the courts of your place of residence, and the mandatory law of that place continues to protect you. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

19Export controls, sanctions, and anti-corruption

You will comply with export control and sanctions laws that apply to your use of inSigner, and you will not use the service to deal with sanctioned persons or embargoed regions. Both parties will comply with applicable anti-bribery laws, including the U.S. Foreign Corrupt Practices Act and the UK Bribery Act.

20Events outside our control

Neither party is responsible for a delay or failure caused by events beyond its reasonable control, such as natural disasters, war, terrorism, labor actions, government orders, widespread internet or power failures, or failures of carriers and major cloud providers. This does not excuse payment obligations.

21General terms

You may not assign these terms without our written consent. We may assign them to an affiliate or to a successor in a merger or acquisition, and we will tell you if that happens. We send notices to the account email, and you send notices to [email protected]. These terms, together with the policies they reference and any signed order, are the entire agreement on this subject.

If a provision is unenforceable, it is limited to the minimum extent needed and the rest remains in force. Not enforcing a provision is not a waiver. These terms are published in English and Spanish. If the versions differ, the English version controls, unless the law of your country requires the version in your language to control.

22Changes to these terms

We may update these terms by publishing a new version with a new date. For a material change that affects paying customers, we will email the account address at least 30 days before it takes effect, unless the change is required by law or fixes a security issue. If you do not agree, you can cancel before the change takes effect. If you keep using inSigner after that date, the new terms apply.
