Frequently Asked Questions

Answers to common questions about subscribing, paying, grievances, and using the 369 DSC Signer desktop utility (PDF Sign, XML Sign, IMG 2 PDF, and signature validation) at 369signer.com.

What is the official website?

The official subscription portal is https://369signer.com. Subscribe, pay, check your status, use Grievance Redressal, and download your 369 DSC Signer package only through this website.

What is 369 DSC Signer?

369 DSC Signer is a desktop utility that lets you digitally sign PDF and XML documents using your Digital Signature Certificate (DSC). It also includes IMG 2 PDF to combine images into a PDF, automatic signature validation when you open already-signed files, and tools to password-protect PDF copies. You subscribe at 369signer.com for Rs. 369 (unlimited signs), and download a personalized Signer package after verification.

The service is operated by an individual (not a company). Any surplus from subscriptions is used for charitable purposes only.

How much does the subscription cost?

The subscription costs Rs. 369 and includes unlimited digital signatures for the subscription period.

How do I subscribe?

Visit https://369signer.com, fill in your name and mobile number, and set a 6-digit PIN. Each subscription is Rs. 369 for unlimited signs. Accept the declaration, continue to the payment page, transfer Rs. 369 to the displayed bank account, then enter your UTRN, upload your payment receipt, accept the non-refundable payment declaration, solve the captcha, and submit your payment proof.

What is the captcha and where is it required?

To protect 369signer.com from automated abuse, you must solve a simple math captcha before submitting certain forms. A captcha is required when you:

  • Submit payment proof after subscribing
  • Submit a new grievance under Grievance Redressal
  • Track an existing grievance under Grievance Redressal

Enter the numeric answer to the math problem shown. If you cannot read it, click the ↻ icon next to the question to get a new one.

What is the 6-digit PIN used for?

Your PIN protects your subscription and grievances. You use it along with your mobile number on the Check Subscription page to view status and download your Signer package. The same PIN is also used to track grievances registered with that mobile number.

How long does payment verification take?

After you submit payment proof, an administrator verifies your bank transfer. You can check your status anytime using your mobile number and PIN on the Check Subscription page. You will be able to download the Signer once your subscription is active.

Are subscription payments refundable?

No. All subscription payments made on 369signer.com are non-refundable. Please verify the subscription amount (Rs. 369 for unlimited signs) before submitting your payment proof.

How do I submit a grievance?

Open Grievance Redressal (main menu). Stay on the Submit Grievance tab and provide your name, mobile number, category, subject, and a detailed description. You may optionally add an email address and up to five supporting documents (PDF, JPG, or PNG, max 5 MB each). Create a 6-digit PIN, solve the captcha, and submit.

After submission you receive an 8-digit tracking number (for example, 00000001). Save this number along with your PIN — you will need them on the Track Grievance tab.

What grievance categories are available?

When submitting a grievance, choose the category that best matches your issue:

  • Payment — issues related to bank transfer or payment proof
  • Subscription — activation, sign count, or subscription status
  • Technical — problems with the Signer desktop utility or signing
  • Other — anything not covered above

How do I track my grievance?

Open Grievance Redressal, then select the Track Grievance tab. Choose one of two options:

  • Mobile Number + PIN — lists all grievances submitted with that mobile number
  • Tracking Number + PIN — looks up a specific grievance using the 8-digit number from your confirmation

Solve the captcha and submit to view full details including status, admin remarks, and any attachments you uploaded. You can also download your supporting documents from the status page.

Which operating system is supported?

At present, the 369 DSC Signer desktop utility supports Windows OS only.

Why sign with a DSC hardware token?

A Digital Signature Certificate on a USB crypto token or smart card keeps your private signing key on hardware you control. That is the standard approach for high-assurance signing in India — legally recognised when issued by a licensed Certifying Authority and accepted by many government and business portals. 369 DSC Signer works with this model: you connect your token, unlock it, and sign PDFs and XML locally.

Is my data uploaded to the cloud when I sign?

No. The desktop Signer performs signing, signature validation, and IMG 2 PDF conversion on your Windows computer. Your PDFs, XML files, and private keys are not sent to 369signer.com for signing. The portal is used only for subscription, payment verification, and downloading your personalised utility — not for processing your confidential documents.

Can I sign documents without internet?

Yes. After your Signer package is downloaded and activated, signing is performed locally on your computer. Sign usage is tracked securely within your licensed package. The desktop utility may connect to the portal occasionally to validate your subscription — but day-to-day signing does not require uploading files online.

What can the 369 DSC Signer desktop utility do?

The Windows Signer includes:

  • PDF Sign tab — open multiple PDFs, place visible signatures by dragging boxes or finding text placeholders, invisible or sign-all-pages modes, custom signature appearance (including drawn signatures and images), certificate details and expiry warnings, password-protect PDF copies, and automatic signature validation when opening already-signed PDFs (with Signature Details)
  • IMG 2 PDF tab — add images, choose layout (one image per page, custom pages with shared page numbers, or all images on one page), adjust brightness/contrast/saturation and colour themes, preview the PDF, and convert to a PDF file
  • XML Sign tab — open XML files, apply enveloped XMLDSig signatures with configurable options, validate signatures automatically on open, and view Signature Details
  • Subscription tab — balance, renewals, and a digitally signed local audit log
  • Preserved signing preferences, collapsible sidebar sections, and header colour themes

Signing and document processing happen locally on your computer. Your DSC private key and files are not uploaded to 369signer.com for signing.

Can I sign XML files?

Yes. Open the XML Sign tab in the desktop utility, select your certificate, open an XML file, configure signature options if needed, then click Sign XML. The utility creates an enveloped XMLDSig signature (SHA-256). Each successful XML sign is recorded in your audit log, the same as PDF signing. You can open already-signed XML to validate it and, if needed, add another signature.

Does the utility validate existing signatures?

Yes. When you open a PDF or XML that already has digital signatures, the utility validates them automatically and shows a compact status banner. Use the top-right Signature Details icon for signer certificate information. You can also place additional signatures on an already-signed document; new PDF signature fields use unique names so they do not clash with existing ones.

How does IMG 2 PDF work?

Open the IMG 2 PDF tab in the desktop utility, add image files, and choose a layout. Use Custom pages when you want only some images on the same PDF page (edit the Page # column). Adjust images if needed, preview the result, then click Convert to PDF.

Conversion is available only when your subscription is active. The conversion step itself does not consume a sign; placing a DSC signature on the converted PDF is recorded in your audit log, like any other document.

After conversion you can choose Sign PDF to open the new file on the PDF Sign tab immediately.

Can I password-protect a PDF?

Yes. On the PDF Sign tab, use Password protect PDF… in the Document section to save a password-protected copy of the PDF currently open in the utility. This is separate from digital signing — it sets an open password on the file copy you save.

How do I renew my subscription?

Current subscriptions include unlimited signs, so you do not need to buy additional sign bundles. If your subscription lapses in the future, renew through the portal at Rs. 369 for another unlimited-sign period.
