Nusii provides an on-line Software as a Service (SaaS) platform that our customers use to design, submit and track proposals to its clients or potential clients. In providing this platform, Nusii processes data that our customers submit to our services or instruct us to process on their behalves. While Nusii’s customers ultimately decide which data to submit, it typically includes information about their clients, sales leads, etc, such as contact information, purchases, and billing information. We process such information in order to be able to provide you with our services.

As part of our marketing strategy, we at Nusii send a newsletter every now and then and we also develop and make available for free from time to time at our website free resources and tools (“Goodies”). In order to access or download such Goodies, we might ask you to subscribe to our newsletter and/or to provide us with limited contact information for marketing purposes.

In both scenarios described above, the legal basis for the processing of your personal data is your informed consent. This is: You provide us with your informed (if you read the legalese) consent, in the process of providing us with any personal data.

Long story short:

  • In the case that you’re not yet a customer of Nusii, but you have in any way or manner subscribed to our newsletter or downloaded any of our Goodies, we use your personal data to contact you every now and then with such newsletter or marketing offers… (Thank you for reading! ;)

  • If you’re already one of our happy customers, we use your data to be able to provide you with our services.

You always have the possibility to manage your data within your registered account with Nusii (online proposal creation and management tool).

We’ll go into further detail below

How does our online platform work and why do we need your personal data?

Nusii’s software offers you the possibility to create and manage your business’s sales proposals, allowing you to better sell your services to clients and potential clients.

The service can be broadened at some point in the future as we try new things, but in essence this is what we do!

All of our services rely on you being a registered user.

How we use your data:

As mentioned above, we need your personal data to facilitate and maintain your role as a registered user of Nusii, and in the case that you’re not yet a customer and you subscribed to our newsletter, to be able to send you our newsletter and/or free content…

International transfers of data

The Nusii website (application) is hosted on the cloud infrastructure of Amazon Web Services (AWS), an American corporation based in Seattle, Washington. The database is managed by Crunchy Data Solutions, Inc., an American corporation.

AWS participates in the EU-U.S. Data Privacy Framework. For more information on AWS’s privacy and compliance practices, please visit https://aws.amazon.com/privacy/

Crunchy Data provides managed PostgreSQL database services with data stored in AWS data centers. For more information on Crunchy Data’s privacy practices, please visit https://www.crunchydata.com/privacy

Compelled disclosure: Please kindly note that Nusii, AWS and/or Crunchy Data may be required, at any time, to disclose personal information in response to lawful requests by public authorities, including to meet national security or law enforcement requirements.

AI assistants (MCP connector)

You can connect your Nusii account to an AI assistant, such as Claude or ChatGPT, through our MCP server at https://app.nusii.com/mcp. This is optional: nothing is shared until you connect an assistant yourself. More about how it works: Connect Nusii to your AI assistant.

What the assistant can access. To connect, you sign in to Nusii and approve the access on our consent screen. The assistant then works as you, in the Nusii account you approved, and only sees what your team role lets you see. It can read your proposals (their sections, pricing, status and dates), your templates, your saved taxes, and your clients’ names, companies and email addresses. It also learns the name of the connected Nusii account and the email address you signed in with, so you can tell your connections apart. If you grant write access, it can also create and edit draft proposals. It can’t send proposals, take payments, or change your account, billing or team settings.

What goes to your AI provider. The data the assistant reads from Nusii goes to the AI provider you chose (for example Anthropic for Claude, or OpenAI for ChatGPT), because the assistant needs it to answer you. Your provider handles that data under its own privacy policy and your agreement with it. Nusii never sends your data to an AI provider on its own, and we don’t receive or keep your conversations with the assistant: we only see the requests it makes to Nusii.

What we log. For each request we record the time, the team member and account, the connected app, the tool that was called and its arguments, the record it touched, whether it failed, the IP address and the app’s user agent. We mask the content of your documents in these logs (section text, titles, names and email addresses). We use the logs to support you, fix problems and protect Nusii from abuse. We keep them for 90 days. Account admins can see them under Settings → API → MCP Logs for the last 30 days (90 days on Business and Enterprise plans). After 90 days, a monthly cleanup deletes them, so no log is older than four months.

Access tokens. The connection uses OAuth access tokens, so the assistant never sees your password. Tokens expire after 24 hours and renew automatically while the connection stays active. You can revoke a connection at any time under Settings → API → Connected AI Assistants, and changing your password revokes all of them. Account admins can also switch off AI assistant access for each team member.

Proposals, clients and other records an assistant creates are normal Nusii data and follow the retention rules below.

How long your data will be stored for:

When your account with Nusii is cancelled, all data associated to that account is deleted within 30 days. After such period of time, the account is permanently cancelled, and thus your data cannot be retrieved. However, if you have used any of our forms to download a freebie or for instance to use a free course, then your email will be retained until you cancel the subscription to that service.

Should you need to contact us to make any changes or request that your personal data be removed, we will do this in the shortest possible amount of time. The maximum time limit for this process to be executed will be 30 days.

Should you continue to maintain any kind of contractual relationship with Nusii (as a customer, or user of our freebies or courses etc.) your data will be stored for the time that is stipulated in the corresponding agreement, as stated above.

Your rights and your data.

What are your rights in relation to your personal data?

You have a whole bunch of rights when it comes to what we do with your data, and you can exercise these rights whenever you choose to do so:

  • Right to access. You can at any time inquire over the personal data that we use at Nusii.
  • Right to modify your personal data.
  • Right to delete your personal data (). The right to be forgotten.
  • Right to limit how your data is used ().
  • Right to oppose our processing of your data (). You can choose to completely remove your data from Nusii. (Save for any contractual/tax data that we might be required to keep.)
  • You can also request a copy of all the personal data we use to run your Nusii account.

(*)Any of the above actions will imply the cancellation of your Nusii account.

You can exercise any of these rights, along with the rest of the rights recognized by the GDPR normative, by writing an email in which you should indicate what it is you’d like to amend/request, to: legal@nusii.com
