This policy explains how Seranova Enterprise LLP ("we", "us"), the company behind SellerZero at sellerzero.com, collects, uses, stores, protects, shares and deletes information when you use our website and service. If you have questions, contact us at info@sellerzero.com.

1. Information we collect

Account information

Your name, email address and password (stored only as a secure hash), or your Google sign-in identity if you choose it.
Company and store names, team members you invite, and their roles.
Two-factor authentication settings.

Data from the accounts you connect

When you authorise SellerZero to access your selling and advertising accounts, we receive, through the marketplace's published interfaces and only for the stores you connect:

Advertising data: campaigns, ad groups, keywords, targets, budgets, bids and performance reports.
Catalogue and stock data: products, listings, prices, listing issues, fulfilment stock and inbound shipments.
Sales and fee data in aggregated form (for example units and revenue by product and day) for reports and profit views.
An authorisation token that lets us call those interfaces on your behalf.

We do not request or store buyers' personal information such as names, addresses, phone numbers or email addresses. If a report we receive contains such fields, we discard them when the report is processed.

Content you provide

Supplier links, product facts, images and text you use in Listing Studio, and creatives you upload.
Rules, schedules, notes and settings you create.

Technical information

Log data such as IP address, browser type, pages requested and timestamps, used for security and troubleshooting.
Essential cookies only: a session cookie to keep you signed in and a security cookie. We do not use advertising or tracking cookies.

2. How we use information

To provide the service you ask for: showing your data, preparing and applying the changes you approve, running your rules and generating listings.
To secure accounts, prevent abuse and fix problems.
To contact you about your account, service changes and, during the beta, product feedback.
To meet legal obligations.

We use data from your connected accounts only to provide SellerZero to you. We do not sell it, do not use it for advertising, and do not combine it with other customers' data to offer services to anyone else.

3. How we store and protect information

Data is stored on secured cloud infrastructure. All connections use HTTPS (TLS 1.2 or later).
Authorisation tokens are encrypted with AES-256-GCM; encryption keys are held separately from the database.
Access is limited by role and by store. Our staff access customer data only when needed to support you, in read-only mode, and every staff action is logged.
Two-factor authentication is required for account owners, admins and our staff.
We test our systems for vulnerabilities and keep software up to date.

4. How we share information

We share information only as follows:

Service providers who help us run SellerZero under contracts that require them to protect the data and use it only for our service: cloud hosting and message queues; an AI provider used only when you use Listing Studio (we send product text and images you supply, never buyer data); and email delivery.
The marketplace you connect, when we apply changes you have approved (for example a new bid or an updated listing).
Legal reasons, when required by law or to protect the rights and safety of our users or the public.
Business transfers, if our company is merged or acquired, in which case this policy continues to apply.

5. Retention and deletion

We keep connected-store data while the store remains connected, so you can see long-term history.
When you disconnect a store, we stop accessing it at once and delete its data within 30 days.
When you close your account, we delete your account and store data within 30 days, and remove it from backups within a further 60 days.
Security logs are kept for up to 12 months. Records we must keep by law are kept only as long as required.

6. Your rights and choices

You can access, correct, export or delete your information from your account settings, or by emailing info@sellerzero.com. You can withdraw consent by disconnecting a store or closing your account. We respond to requests within 30 days.

7. Security incidents

If we become aware of a security incident affecting your information, we will notify you and the relevant marketplace without undue delay (and within 24 hours where required), along with any authorities as required by law.

8. International transfers

Our service providers may process data outside India. Where they do, we use providers with appropriate safeguards and contracts.

9. Children

SellerZero is a business service and is not meant for anyone under 18. We do not knowingly collect children's data.

10. Changes to this policy

We will post any changes here and update the date above. For significant changes we will email account owners before they take effect.
