Privacy Policy

Last updated: 10 October 2026

Khulna Technologies LLC ("KTL", "we", "us") operates SigningUS, an electronic signature and document collection platform. This policy explains what personal data we collect, how we use and share it, and the rights you have. It applies to signingus.com and to the SigningUS application.

Who is responsible for your data. Khulna Technologies LLC, a limited liability company organized under the laws of Maryland, 4520 East-West Highway #780, Bethesda, MD 20814, United States, is the controller of the account, website and usage data described in this policy.

For the content customers send through SigningUS, including documents, files and the personal data of signers, the customer is the controller and KTL processes that data on the customer's instructions. Those terms are in our Data Processing Agreement.

01

Information we collect

Account information. Your name, email address, password (stored only as a hash), organization name and role. If you sign in with Google, we receive your name, email address and profile image from Google.

Content you send and receive. The documents you upload, the fields you place, and the signed documents. Where a sender asks a signer for a supporting file, such as an image of an identification document, we store that file with the document on the sender's instructions.

Signer information. When a document is sent to you for signature, we process your name and email address, your IP address, the time you sign, the signature you apply, and any file you upload at the sender's request. You do not need a SigningUS account to sign.

How signing requests reach signers. SigningUS sends signing invitations, verification codes and completion emails by email only. A sender may also copy a signing link and share it through an app of their choice, such as WhatsApp. A message sent that way goes through that app under its own terms, not through SigningUS.

Billing information. Paid plans are billed through our payment processor, Stripe. Card details are entered on Stripe's checkout page and go directly to Stripe. We do not receive or store full card numbers.

Website and usage data. Browser and device type, IP address and application logs, used to keep the service secure and working. On our public website we use Google Analytics, through Google Tag Manager, to understand how visitors use the site, including pages visited.

02

How we use your information

  • To provide the service: routing signing requests, applying signatures, storing documents and recording what happened to each document.
  • To secure accounts and the platform, prevent fraud and impersonation, and fix problems.
  • To bill for paid plans and process refunds.
  • To communicate with you about your account, answer support requests and send service and security notices.
  • To send product updates where permitted. You can opt out at any time. Service and security notices continue regardless.

Artificial intelligence. We do not use customer content, signer data or uploaded identification documents to train artificial intelligence models, and we do not send this content to any AI provider.

04

How we share information

With the people in a document. Content in a document is shared with the recipients the sender designates.

With subprocessors. We use a small number of service providers who process data on our behalf under written contracts. Each is named at signingus.com/subprocessors. We do not use any identity-verification service: an identification file a signer uploads is not sent to any verification provider.

For legal reasons. Where the law requires it, or where necessary to protect the rights, property or safety of KTL, our users or the public.

On a change of control. If KTL is involved in a merger, acquisition or sale of assets, we will give notice before personal data is transferred and becomes subject to a different privacy policy.

We do not sell your personal data and do not share it for advertising.

05

Cookies and similar technologies

The SigningUS application does not set its own cookies. It keeps your session, name, email address and display preferences in your browser's local storage, and signing out clears them, except display preferences. Our public website uses cookies for security and analytics. Details are in our Cookie Policy.

06

08

Security incidents

If a personal data breach affects you, we will notify affected customers without undue delay and, where feasible, within 72 hours of becoming aware of it, and will notify supervisory authorities where the law requires.

09

Your rights

Depending on where you live, you may have the right to access, correct, export, restrict or delete your personal data, to object to certain processing, and to withdraw consent. Email privacy@signingus.com. We may need to verify your identity, and we respond within the period the applicable law requires.

If you are a signer without a SigningUS account, the sender controls the document. You can contact the sender directly, or contact us and we will pass your request to them.

If you are in the EEA, the UK or Switzerland, you may also complain to your local supervisory authority.

We process identification documents only on the sender's instructions and do not use them to infer anything about you. We will not discriminate against you for exercising a privacy right. You may use an authorized agent; we may ask for proof of authorization.

International transfers

Our application and database are hosted with Amazon Web Services in the United States. Documents are stored with Cloudflare, which also delivers our website and application through its global network. Email is sent through Amazon Web Services in the United States. Members of our team in Bangladesh access data to develop, run and support the service.

For transfers from the EEA, the UK or Switzerland, we rely on the European Commission's standard contractual clauses and, for the UK, the international data transfer addendum.
