Privacy Policy

Last updated: 16 October 2026

InvoiceInk is provided by Clarity Technologies, India ("we", "us"). This policy explains what personal data InvoiceInk handles, why, who it is shared with, and the choices you have. It is written to meet the Digital Personal Data Protection Act, 2023 and the Information Technology Act, 2000 and its rules.

Two roles we play

  • For your account, such as your name, email address and sign-in details, we decide how the data is used. We are the data fiduciary.
  • For what you put into InvoiceInk about your business and your customers, such as customer names, contacts, addresses, tax numbers, invoices and payments, your organization decides why that data is processed. We process it on your behalf and only to provide the service. Your organization is responsible for having a lawful basis to collect it and for answering your customers' requests about it.

What we collect

  • Account details: name, email address, password (stored only as a one-way hash), two-factor authentication settings, an optional profile photo, and the organizations you belong to and your role in each.
  • Organization details: business name, legal name, addresses, phone, emails, tax and registration numbers, bank details you choose to print on invoices, logo, numbering settings and email templates.
  • Customer and document data: the customers, invoices, estimates, line items, payments, attachments and notes you create.
  • Email records: who each invoice, estimate or reminder was sent to, when, and whether delivery succeeded.
  • Connected apps: when you connect an AI assistant such as Claude, the app's name and the access tokens issued to it.
  • Technical data: IP address, browser and device details, and session records, used to keep you signed in and to protect the service. Our servers also keep error logs.

We do not use advertising or analytics trackers, and we do not sell personal data.

How we use it

  • To provide InvoiceInk: create and store documents, generate PDFs, send emails you ask us to send, and show reports.
  • To secure the service: authentication, two-factor checks, rate limits, preventing abuse, and investigating errors.
  • To contact you about your account, security, and changes to the service or these terms.
  • To comply with the law and respond to lawful requests.

We process your account data because you asked us to provide the service, and on the other legitimate grounds the law allows.

AI features

AI features are off until an owner or admin turns them on for an organization, under Settings → AI features. When they are on and you use one, such as drafting an invoice from a message or document, writing an email, or suggesting a tax code, the text, files and invoice details involved are sent to Anthropic, our AI provider, to produce the result. Under its commercial terms Anthropic does not use this content to train its models. Results are suggestions: nothing is saved or sent until someone reviews it. The documents you draft from are not stored by InvoiceInk; a draft is kept for up to 30 minutes so you can open it.

Connected AI tools

If you connect an AI assistant under Settings → Connect AI tools, it can read, but never change, the data of the organization you are currently in, for as long as it stays connected. You can disconnect it on that page at any time.

Who we share it with

We use the following service providers to run InvoiceInk. Each receives only what it needs for its task.

  • Google Cloud (Mumbai, India): runs the application, background jobs and logs. Error alerts are sent to our team through Google Chat.
  • DigitalOcean (Bengaluru, India): hosts the database.
  • Amazon Web Services (Mumbai, India): stores logos, attachments and other files.
  • Cloudflare (global network): delivers and protects traffic to the site.
  • Brevo (European Union): delivers the emails InvoiceInk sends. It may record delivery events, such as whether a message was delivered or opened.
  • Anthropic (United States): only when AI features are on and used, as described above.
  • Bunny Fonts and UI Avatars: your browser loads fonts from Bunny Fonts, and, when you have no profile photo, a placeholder image made from your initials from UI Avatars.

When you send an invoice, estimate or reminder, its recipients receive what you send. A shared document link lets anyone holding it view that document until the link expires after 30 days.

We may disclose data when required by law, or to protect the rights, property or safety of our users, the public or us. If our business is reorganized or transferred, data may move with it under the same protections.

Where it is stored

Your data is stored in India. Some providers above process it outside India, in line with the transfers Indian law permits.

How long we keep it

We keep your data while your account is active. When you delete your account, your account is deleted, along with any organization you own that has no other members. Copies in backups and logs expire after a limited period. Files prepared for emails are deleted within 48 hours.

Tax and accounting laws may require your business to keep invoices for several years. Keeping your own copies is your responsibility, so download what you need before deleting anything.

Security

Traffic is encrypted in transit, passwords are hashed, and two-factor authentication is available. Access inside an organization follows its members' roles. No system is perfectly secure; if a breach affects your personal data, we will notify you and the authorities as the law requires.

Your rights

You can ask us to:

  • tell you what personal data we hold about you and how it is processed;
  • correct, complete or update it;
  • erase it, unless we must keep it by law;
  • name someone to exercise these rights for you if you die or become unable to.

You can update most account details and delete your account yourself from your profile. Where we rely on your consent you may withdraw it at any time, which does not affect processing already done.

If your data was added to InvoiceInk by a business that invoices you, please contact that business first; we will help it respond.

Cookies

We use only the cookies InvoiceInk needs to work: a session cookie to keep you signed in, a security token that protects forms, an optional "remember me" cookie, and one that remembers your light or dark theme.

Children

InvoiceInk is for businesses and is not meant for anyone under 18. We do not knowingly collect children's data.

Changes

We may update this policy. If a change is significant, we will tell you by email or in the app before it takes effect. The date at the top shows the latest version.

Contact and grievances

For questions, requests or complaints about your personal data, write to our Grievance Officer at support@claritytech.io. We will acknowledge your message promptly and respond within 30 days. If you are not satisfied with our response, you may complain to the Data Protection Board of India.
