Publisher Privacy Policy

Last updated: December 08, 2025

1. Introduction

OSS Lab is an operational-intelligence publication created by Online Seller Solutions. Our purpose is to give Amazon operators clarity, real explanations, real patterns, and field-tested intelligence they can apply.

Because OSS Lab is hosted on Substack, your personal information is handled at two levels:

1. Substack, which collects and processes data to operate the platform.

2. OSS Lab, which uses the information Substack shares with us to deliver the publication and support your subscription.

This Privacy Policy explains how OSS Lab uses the data we receive. For anything related to how Substack collects, stores, or uses your information, their own Privacy Policy applies.

2. Data Collection

We only receive the information Substack shares with creators. This may include:

2.1 Information you provide

• Email address

• Name (if you choose to include it in your Substack profile)

• Subscription status (free or paid)

For paid plans, payment information is processed entirely by Substack and its payment partners. OSS Lab never sees or stores your full payment details.

2.2 Information collected by Substack

Substack may collect device data, IP addresses, cookies, and engagement metrics such as opens and clicks.

OSS Lab may view aggregated analytics within the Substack dashboard, but we do not control the collection methods and do not add additional tracking.

For details on platform-level data collection, refer to Substack’s Privacy Policy.

3. How We Use Your Information

We use the information Substack provides for one purpose: operating OSS Lab effectively and responsibly.

3.1 Delivering the publication

• Sending free or premium editions

• Sending welcome emails, subscription notices, and renewal reminders

• Communicating essential updates about the publication

3.2 Improving operational clarity for subscribers

We use platform analytics, such as which posts are opened or which topics track higher interest, to refine OSS Lab and make it more relevant, precise, and useful.

3.3 Supporting subscribers

We use your contact information to respond to questions, address subscription issues, or provide assistance related to OSS Lab.

We do not use your information for unrelated marketing, sell subscriber data, or share it for advertising purposes.

4. Data Sharing

4.1 Substack and its service providers

Your information is stored and processed by Substack and its trusted partners (for payments, email delivery, security, hosting, and analytics). Their privacy practices govern platform-level processing.

4.2 OSS Lab

OSS Lab does not sell, rent, or share subscriber data with third parties for independent marketing or advertising.

We only disclose information:

• When required by law

• When necessary to protect our rights, security, or the integrity of the publication

We do not add third-party tracking or external marketing pixels.

5. Subscriber Rights

Your rights exist on two levels: with Substack and with OSS Lab.

5.1 Your rights with Substack

Substack is the data controller for platform-level information. Through your Substack account, you may:

• Access or update your profile information

• Adjust email preferences

• Manage or delete your account

• Revoke access to connected third-party services

For any rights related to data Substack collects directly, refer to Substack’s Privacy Policy.

5.2 Your rights with OSS Lab

For the data we use (email address, name, subscription status), you may:

• Access or update your information via Substack

• Unsubscribe at any time

• Request removal of your information from any off-platform lists we maintain (if applicable; OSS Lab operates primarily within Substack)

To contact us regarding your data, email: privacy@onlinesellersolutions.com

Please note: removing your information from OSS Lab does not delete your Substack account. That must be handled directly through Substack.

6. Changes to This Privacy Policy

As OSS Lab evolves, we may update this Privacy Policy to ensure clarity and compliance.

If changes occur, we will:

• Post the updated policy on our Substack publication

• Notify subscribers when the update is meaningful
