Overview
You connect your Amazon Seller Central and Amazon Ads accounts to SellerApp so we can help you grow. That takes trust, and the General Data Protection Regulation (GDPR) spells out exactly what we owe you in return.
This page explains how Sellmetric Pte Ltd, the company behind SellerApp, handles the personal data of people in the European Economic Area and the United Kingdom. It covers what is already in place and what we are still working on.
Think of it as the plain-English companion to our Privacy Policy. The Privacy Policy is the full legal notice. This page is for procurement teams, privacy reviewers, and anyone who would like a straight answer without reading forty clauses to get it.
SellerApp and the GDPR at a glance
| Question | Short answer |
|---|---|

| Which laws this page covers | EU GDPR (Regulation (EU) 2016/679), UK GDPR, and the UK Data Protection Act 2018 |
| Our role | Controller for website, lead, account, and billing data. Processor for data you bring in from marketplace and advertising accounts |

| Do we collect your buyers’ personal data | No. SellerApp works on seller account data |

Who we are and the two roles we play
SellerApp is operated by Sellmetric Pte Ltd, 140 Paya Lebar Road, #10-09, AZ @ Paya Lebar, Singapore 409015. Our United States office is at 4819 Bryant Mdws Dr, Spring, TX 77386. We also have a team in India.
Because we are based outside the EU and the UK and offer our services to businesses there, the GDPR applies to us under Article 3(2).
Under the GDPR, a company can be a controller, a processor, or both. We are both, and which one depends on the data.
When we are the controller. We decide why and how the data is used. That covers visitors to sellerapp.com, people who fill in a form or book a demo, account holders and their team members, and billing contacts.
When we are the processor. You decide why and how the data is used, and we act on your instructions. That covers the data that flows in when you connect Amazon Seller Central, Amazon Ads, or another marketplace or advertising account. It also covers client data that agencies manage on our platform. In those cases you are the controller, and our Data Processing Agreement sets the rules we follow.
What we process, why, and on what lawful basis
Every use of personal data needs a lawful basis under Article 6 of the GDPR. Here is ours, activity by activity.
| What we process | Whose data | Why | Lawful basis | Our role |
|---|---|---|---|---|
| Website technical data such as IP address, device, browser, and pages viewed | Site visitors | Keep the site running and secure | Legitimate interests, Article 6(1)(f) | Controller |
| Analytics and profiling cookies | Site visitors | Understand what works and measure campaigns | Consent, Article 6(1)(a) | Controller |
| Lead and demo forms with name, work email, phone, company, and job title | Prospects | Answer your request and set up a demo | Steps taken at your request before a contract, Article 6(1)(b) | Controller |
| Newsletters, webinar invitations, and marketing email | Subscribers and leads | Send news you asked for | Consent, Article 6(1)(a) | Controller |
| Account registration and onboarding with name, email, login credentials, company, and team members | Customers and their users | Create and run your account | Contract, Article 6(1)(b) | Controller |
| Billing contact, billing address, tax ID, and payment status. Card details are handled by Stripe | Customers | Take payment and keep tax records | Contract, Article 6(1)(b), and legal obligation, Article 6(1)(c) | Controller |
| Support tickets, emails, and sales or strategy calls | Customers and prospects | Solve problems and follow up | Legitimate interests, Article 6(1)(f) | Controller |
| Product usage and security logs | Users | Fix bugs, improve the product, and detect abuse | Legitimate interests, Article 6(1)(f) | Controller |
| Chrome extension data such as ASINs, titles, and prices on Amazon pages, plus search terms you enter in the extension | Extension users | Show research data on Amazon pages | Contract, Article 6(1)(b) | Controller |
| Marketplace and advertising account data such as account identifiers, API tokens, listings, sales, order, and campaign metrics | Customers | Deliver the analytics, automation, and reporting you signed up for | Set by you as the controller. We act on your documented instructions under Article 28 | Processor |
Lead forms are voluntary. If you would rather not fill one in, the rest of the site works the same.
In addition, a few things we do not do.
- We do not sell personal data.
- We do not collect the personal information of your buyers.
- We do not ask for special category data under Article 9, such as health or biometric data, and we ask that you do not send us any.
- Our services are built for businesses and are not directed at children under 16.
Amazon and marketplace account data
To use SellerApp, you connect Amazon Seller Central and the Amazon Ads console. That connection is where most of the data in your account comes from, so here is how we treat it.
- Access runs through official APIs. We reach your data through authorized marketplace and advertising APIs, with the permissions you grant during onboarding.
- You stay in control. You can revoke our access at any time from your Amazon account.
- We use it for your service and nothing else. We do not use marketplace, advertising, or extension data for behavioral advertising or for profiling unrelated to the services you asked for.
- We work with seller data, not buyer data. SellerApp does not collect the personal information of your buyers, such as names, addresses, or contact details. Our analytics run on seller-level data like listings, sales, inventory, and campaign performance.
- Most of it is business data. ASINs, listings, prices, and campaign metrics describe products and performance, not people. That said, data about a sole trader can count as personal data, and we treat it accordingly.
- Amazon’s rules apply too. As a Selling Partner API developer, we are bound by Amazon’s Data Protection Policy and Acceptable Use Policy on top of the GDPR.
The same approach applies to the other platforms you connect, such as Walmart, Instacart, Flipkart, Google Ads, and Meta.
Cookies and the three categories that matter
Not all cookies are equal, and the law treats them differently. We sort ours into three groups, and only the first group runs without your say-so.
| Category | What it does | Typical examples | Needs your consent | Your control |
|---|---|---|---|---|
| Technical cookies | Keep you signed in, remember your cookie choice, and protect the site | Session, security, and preference cookies | No. These are strictly necessary and exempt under Article 5(3) of the ePrivacy Directive | Always on. You can block them in your browser, although parts of the site will stop working |
| Analytics cookies | Count visits and show us which pages help and which do not | Visit counts, traffic sources, and page performance | Yes | Set only if you accept |
| Profiling cookies | Build a picture of your interests across sites so ads can be targeted and measured | Advertising pixels and remarketing tags | Yes | Set only if you accept |
In practice, that means the following.
- Where the law requires consent, analytics and profiling cookies are set only after you accept them through our cookie banner.
- You can decline them, and the site works either way.
- You can change your choice at any time through the cookie banner or your browser settings.
- We honor Global Privacy Control signals from your browser where the law requires it.
These rules come from the ePrivacy Directive in the EU and the Privacy and Electronic Communications Regulations in the UK, which work alongside the GDPR.
Where your data lives and who helps us process it
SellerApp runs on Cloud infrastructure. We operate the service from the United States, Singapore, and India, and data is stored and processed through cloud and IT providers located in or operating from those countries. Our teams access personal data only as needed to provide support and services.
International transfers
The United States, Singapore, and India are outside the European Economic Area and the UK. Therefore, when personal data covered by the GDPR is transferred to those countries, Chapter V requires an appropriate safeguard.
We rely on the safeguards the law recognizes. These include the European Commission’s Standard Contractual Clauses (Decision 2021/914) and the UK International Data Transfer Addendum, where they apply. Both are incorporated into our Data Processing Agreement, and you can ask for a copy at legal@sellerapp.com.
How long we keep data and what happens when you leave
We keep personal data only as long as we need it for the purpose it was collected for, as Article 5(1)(e) requires. After that, we delete it or strip out anything that identifies you.
| Data | How long we keep it |
|---|---|
| Account and user profile data | For as long as your account is active, and afterward only as long as needed to close out the relationship, resolve disputes, and meet legal obligations |
| Connected marketplace and advertising data | For as long as the account stays connected and you use the service. You can ask us to delete it at any time |
| Invoices and billing records | For the period that tax and accounting laws require |
| Lead and enquiry data | Until your enquiry is dealt with and for a reasonable follow-up period, unless you ask us to stop sooner |
| Marketing contacts | Until you unsubscribe or withdraw consent |
| Support and call records | As long as needed to resolve the issue and keep a record of the service we provided |
Once data is no longer needed, we delete or anonymize it. Before you close your account, you can ask for a copy of your personal data. Email legal@sellerapp.com and we will provide it in a commonly used, machine-readable format.
How we protect your data
Article 32 asks for security that fits the risk. We would rather tell you what we do than wave a badge around, so here it is.
- Encryption in transit for data moving between you, us, and the marketplaces
- Role-based permissions, so people see only what their job needs
- Access controls that limit who can reach personal data
- Administrative, technical, and physical safeguards against loss, misuse, and unauthorized access
- Amazon’s Data Protection Policy requirements for the data we reach through its APIs
No system is perfectly secure, and anyone who says otherwise is selling something. What we can promise is that we take it seriously and tell you quickly if something goes wrong.
If there is a breach
If a personal data breach happens, here is what we commit to.
- As a controller. We notify the relevant supervisory authority within 72 hours of becoming aware of a breach that puts people at risk, as Article 33 requires. Where the risk to individuals is high, we tell them directly without undue delay under Article 34.
- As a processor. We notify the affected customer without undue delay after becoming aware, as Article 33(2) requires, with the details they need to meet their own obligations.
Your rights and how to use them
If you are in the EEA or the UK, the GDPR gives you these rights over your personal data.
| Right | What it means | Article |
|---|---|---|
| Access | Get a copy of the personal data we hold about you | 15 |
| Rectification | Have inaccurate data corrected | 16 |
| Erasure | Have your data deleted, also called the right to be forgotten | 17 |
| Restriction | Ask us to pause processing while a concern is resolved | 18 |
| Portability | Receive your data in a machine-readable format or have it sent to another provider | 20 |
| Objection | Object to processing based on legitimate interests, and to direct marketing at any time | 21 |
| Withdraw consent | Take back consent you gave, such as for cookies or marketing | 7(3) |
| Complaint | Lodge a complaint with a data protection authority | 77 |
How to make a request
- Email legal@sellerapp.com and tell us which right you would like to use.
- We confirm your identity, so nobody else can get hold of your data.
- We respond within one month. For complex requests the GDPR allows up to two more months, and we will tell you if we need them.
Requests are free of charge. You do not need to give a reason.
However, if we hold your data on behalf of a SellerApp customer, for example because you are a team member or client of a business that uses our platform, that customer is the controller. We will pass your request to them and help them respond.
How to complain
We would like the chance to fix a problem first, so please write to us. You also have the right to complain to your local data protection authority at any time. In the EU, you can find yours through the European Data Protection Board. In the UK, it is the Information Commissioner’s Office.
Data Processing Agreement
If you are subject to the GDPR and we process personal data for you, Article 28 requires a written contract between us. We offer a Data Processing Agreement to any customer who needs one. Email legal@sellerapp.com and we will send it for signature.
The agreement covers the points Article 28(3) lists.
- We process personal data only on your documented instructions
- Everyone with access is bound by confidentiality

Frequently asked questions
Is SellerApp GDPR compliant?
SellerApp has built its data practices around the GDPR and the UK GDPR, and this page shows the work. Compliance is an ongoing obligation and not a one-time certificate, so our roadmap lists what is finished and what is still underway.
Does the GDPR apply to SellerApp if the company is based in Singapore?
Yes. Article 3(2) applies the GDPR to companies outside the EU that offer goods or services to people in the EU. We serve customers in the EEA and the UK, so the EU GDPR and the UK GDPR both apply to that processing.
Is SellerApp a data controller or a data processor?
Both. We are the controller for website, lead, account, and billing data. We are a processor for the marketplace and advertising data you connect to the platform, where you are the controller and we act on your instructions.
Does SellerApp access my Amazon customers’ personal data?
No. SellerApp works with seller account data such as listings, sales, inventory, and campaign performance. We do not collect the personal information of your buyers.
Where does SellerApp store my data?
SellerApp is hosted on Google Cloud infrastructure and operated from the United States, Singapore, and India. Transfers of personal data out of the EEA and the UK are covered by safeguards recognized under Chapter V of the GDPR, including Standard Contractual Clauses where they apply.
Does SellerApp sell my data?
No. We do not sell personal data, and we do not use marketplace, advertising, or extension data for behavioral advertising or unrelated profiling. We may produce anonymized, aggregated insights such as category trends, which cannot be linked back to you.
Who handles privacy at SellerApp?
Privacy and data protection matters are handled by our legal team. You can reach them at legal@sellerapp.com.
How do I get a Data Processing Agreement?
Email legal@sellerapp.com. We provide our Data Processing Agreement to any customer who needs one under Article 28.
How do I delete my SellerApp data?
Email legal@sellerapp.com and ask for erasure. We confirm your identity and respond within one month. You can also disconnect your marketplace accounts at any time, which stops further collection.
Which cookies does SellerApp use?
Three kinds. Technical cookies keep the site working and are always on. Analytics cookies and profiling cookies are off until you accept them, and you can change your choice at any time through our cookie banner or your browser settings.
