Terms, Cancellation & Refund Policy

These documents govern your use of the Fulfillin platform. Part 1 sets out the Terms and Conditions of service, including our cancellation, refund, and acceptable-use policies. Part 2 explains how we collect, process, and protect personal data in compliance with the General Data Protection Regulation (EU) 2016/679 (GDPR) and applicable Latvian data protection law.

Fulfillin is a business-to-business (B2B) service. By creating an account, you confirm that you are acting in a commercial or professional capacity, not as a consumer.

1. Service Description

Fulfillin provides software tools for multichannel marketplace sellers, including Mirakl order management, marketplace integrations, messaging (atinbox), and related services. By creating a Fulfillin account, you agree to these terms.

All Fulfillin products — including atinbox — are operated by Mayfair SIA. Account creation, authentication, and billing are managed under fulfillin.com regardless of which product you use.

2. Accounts and Access

Your Fulfillin account gives you access to all Fulfillin products. You are responsible for maintaining the security of your account credentials and for all activity that occurs under your account. You must not share credentials with unauthorised parties or use the platform on behalf of any third party without our prior written consent.

3. Cancellation Policy

You may cancel your subscription at any time from your account settings. There is no minimum commitment period and no cancellation fee.

What happens when you cancel:

•    Your subscription remains active until the end of the current billing period.

•    You will not be charged for the following period.

•    Usage charges already incurred up to the cancellation date remain payable.

•    Your account data is retained for 90 days after cancellation, then permanently deleted. You may request earlier deletion by contacting us at our email address.

•    Downgrading to the free tier is treated as a cancellation of your paid plan. The free allowance remains available indefinitely.

4. Refund Policy

Monthly subscriptions: Subscription fees are non-refundable once a billing period has begun. If you cancel mid-period, you retain access until the end of that period, but no partial refund is issued.

Usage charges: Pay-as-you-go and overage charges reflect actual usage and are non-refundable.

Exceptions: If a billing error occurs on our part, or if the service is unavailable for a continuous period exceeding 72 hours due to issues on our end, you may request a credit or refund for the affected period by contacting us at our email address within 30 days of the incident. We will review all such requests and respond within 5 business days.

We do not issue refunds for change of mind, failure to use the service, or misunderstanding of features. We encourage you to use the free allowance to evaluate the service before upgrading to a paid plan.

5. Service Availability

We aim to maintain high availability, but do not guarantee uninterrupted service. Planned maintenance will be communicated in advance where possible. We are not liable for downtime caused by third-party services, marketplace platforms, or factors outside our reasonable control.

6. Acceptable Use

You agree not to use Fulfillin to:

•    Violate any applicable law or regulation.

•    Infringe the intellectual property or other rights of any third party.

•    Distribute spam, malicious content, or unauthorised communications via connected marketplace accounts.

•    Attempt to gain unauthorised access to any system, account, or data.

•    Resell or sub-license access to the platform without our prior written consent.

We reserve the right to suspend or terminate accounts that breach these terms, without prior notice, where the breach is material or causes harm to other users or third parties.

7. Intellectual Property

All software, algorithms, interfaces, content, and documentation forming part of the Fulfillin platform are the exclusive property of Mayfair SIA. Nothing in these Terms grants you any rights in the platform beyond the limited access right described in clause 1. Your account data remains your property; we do not claim ownership of any data you import or process through the platform.

8. Limitation of Liability

To the maximum extent permitted by applicable law:

•    Mayfair SIA's total liability to you for any claim arising from use of the service is limited to the fees you paid in the three months preceding the claim.

•    We are not liable for indirect, incidental, or consequential damages, including loss of profit, loss of revenue, or loss of data.

•    We are not responsible for the availability, accuracy, or terms of any third-party integration (Linnworks, Mirakl, Amazon, Veeqo, Kaufland, or any carrier or fulfilment platform).

9. Your Obligations

You agree to:

•    Keep your integration credentials (API keys, access tokens) secure and do not share them with unauthorised parties.

•    Notify us immediately at our email address if you become aware of any unauthorised access to your account or credentials.

•    Use Fulfillin only for lawful business purposes and in compliance with the terms of any marketplace or platform whose data you connect.

•    Ensure you have the necessary rights and permissions to connect the accounts and data sources you integrate with Fulfillin.

Our Privacy Policy (Part 2) governs how we collect and process personal data in connection with the service. A Data Processing Agreement (DPA) is available on request at our email address.

10. Changes to These Terms

We may update these terms from time to time. We will notify you of material changes by email or via an in-app notice at least 14 days before the changes take effect. Continued use of the service after that date constitutes acceptance of the updated terms.

11. Governing Law

These terms are governed by the laws of the Republic of Latvia. Any disputes shall be subject to the exclusive jurisdiction of the courts of Riga, Latvia. Nothing in these terms limits rights available under applicable EU law.

2. Personal Data We Collect

We process personal data only to the extent necessary to provide the Fulfillin service. The categories of personal data we process are:

•    Order data: end-customer names, delivery and billing addresses, email addresses, phone numbers (where provided by the marketplace), order identifiers, and purchase details.

•    Inventory data: product SKUs, stock levels, pricing, and product identifiers synced from your connected platforms.

•    Messaging data: the content of marketplace customer messages associated with your seller account, including sender identifiers and timestamps.

•    Account data: your name, business name, email address, and API credentials used to configure your integrations.

•    Usage and statistical data: anonymised or pseudonymised data about how the platform is used — such as order volumes, sync frequencies, and error rates — used to operate and improve the service.

We do not knowingly process special category data (e.g., health, race, biometric data) or personal data of children.

3. How and Why We Use Your Data

The table below sets out each processing purpose, the legal basis under GDPR, and the data categories involved.

4. Data Retention

We retain personal data only for as long as necessary for the purposes set out in this Policy:

•    Statistical and analytics data: retained in pseudonymised form for up to 36 months.

•    Account data: retained for the duration of your contract and deleted within 60 days of termination, unless longer retention is required by law (e.g., tax records, which may be retained for up to 10 years under Latvian law).

You may request early deletion of your data — subject to legal retention obligations — by contacting us at our email address.

5. Who We Share Data With

We do not sell personal data. We share data only in the following circumstances:

•    Integrated platforms: order, inventory, and messaging data is transmitted to and from Linnworks, Mirakl, Amazon, Veeqo, Kaufland, and other connected channels as part of the core service. Each integration is governed by its own terms and privacy policy.

•    Cloud infrastructure providers: we use third-party hosting and database providers to store and process data securely. These providers act as sub-processors under appropriate data processing agreements.

•    Legal requirements: we may disclose data if required by law, court order, or a competent regulatory authority.

•    Business transfers: in the event of a merger, acquisition, or sale of assets, data may be transferred to the successor entity, subject to equivalent data protection obligations.

6. International Data Transfers

Some of the third-party platforms we integrate with — including Amazon — are operated by entities outside the European Economic Area (EEA). Where personal data is transferred outside the EEA, we ensure appropriate safeguards are in place, including:

•    Standard Contractual Clauses (SCCs) approved by the European Commission, where required.

•    Transfers to countries covered by an EU adequacy decision.

You may request details of the specific safeguards applicable to any transfer by contacting us at our email address.

7. Data Security

We implement appropriate technical and organisational measures to protect personal data against unauthorised access, loss, or disclosure. These include:

•    Encryption of data in transit (TLS) and at rest.

•    Access controls limiting data access to authorised personnel only.

•    Regular security reviews and vulnerability assessments.

•    Incident response procedures to detect, report, and respond to data breaches within 72 hours as required by GDPR Art. 33.

In the event of a breach affecting your data, we will notify you without undue delay.

8. Your Rights Under GDPR

As a data subject (or as the Data Controller responsible for your end-customers' data), the following rights apply under GDPR Articles 15–22:

To exercise any of these rights, contact us at our email address. We will respond within 30 days. Where requests are complex or numerous, we may extend this by a further 60 days with notice.
