Postier exists for independent creators who care deeply about product quality and brand identity. Developed by Holt Base LLC, we build practical, automated workflows that help e-commerce sellers create high-impact Pins, optimize their search visibility, and publish with complete confidence.

Why We Built Postier

At Holt Base LLC, we understand the e-commerce grind because we've lived it. Postier was born out of a frustrating bottleneck our team faced firsthand while running our own online shops.

Running an e-commerce business is a grueling, multi-faceted job. Between designing new products, manufacturing inventory, managing shipping logistics, and ensuring every single customer is happy, marketing is almost always the first thing to get pushed aside.

We know exactly what it feels like to be trapped in the Growth Loop:

Breaking the Cycle

Holt Base LLC developed Postier to break this exact cycle once and for all. Our mission is simple: to give you your hours back while keeping your store's digital presence looking exceptionally polished and professional.

By automating the heavy lifting of visual content creation and scheduling, Postier helps you unlock the consistent traffic and revenue you need to scale your business, hire that extra hand, and finally get your own life back.

While our roots are in the maker community and we are avid fans of the Etsy marketplace, Postier is a completely independent software suite and is not an official Etsy-owned or Etsy-endorsed product. We are proud to build tools that help independent sellers achieve their goals on their own terms.

Holt Base LLC ("we," "our," or "us") respects your privacy and is committed to protecting the personal data of our users. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you visit our website, Postier.io, and use our SaaS application (collectively, the "Service").

By using the Service, you agree to the collection and use of information in accordance with this Privacy Policy.

1. Information We Collect

We collect several types of information from and about users of our Service to provide and improve our application.

Account Information: When you register for Postier, we collect your name, email address, and account credentials.

Billing Information: Paddle.com, our Merchant of Record and authorized reseller, collects and processes your payment details directly through its own secure checkout. We do not receive, process, or store your full payment card information. Paddle shares limited transaction data with us (such as your email, purchase date, and subscription status) so we can manage your account and provide support.

Connected Platform Data: When you authorize Postier to connect to your e-commerce platforms (such as Etsy or Shopify), we authenticate strictly via OAuth 2.0 to retrieve product titles, descriptions, images, and shop metadata. We never request, collect, or store your Etsy, Shopify, or Pinterest passwords.

Usage and Technical Data: We automatically collect data regarding how the Service is accessed and used. This may include your IP address, browser type, device identifiers, time zone, and interaction data within the Postier dashboard.

2. How We Use Your Information

We use the collected data for the following core purposes:

• To provide, maintain, and operate the Service (including automating social media generation and publishing).
• To process transactions and manage your subscription.
• To communicate with you regarding account updates, customer support, and system maintenance.
• To monitor usage patterns and identify technical issues or bugs.
• To ensure compliance with our Terms of Service and prevent fraudulent or abusive activity.

3. Third-Party Service Providers and Data Sharing

We do not sell your personal information to third parties. However, because Postier is an automation platform, we must share specific, limited data with trusted third-party providers to function:

OpenAI (Generative AI): We transmit your e-commerce product data (titles, descriptions, and images) to OpenAI's API to generate optimized marketing copy. Data sent to OpenAI via their API is explicitly excluded from being used to train their public models.

Cloudflare (Storage): We temporarily store generated images and assets on Cloudflare R2 infrastructure before publishing them.

Pinterest (Publishing): We transmit generated pins, images, and text to the Pinterest API to publish content to your authorized boards.

Infrastructure & Analytics: We utilize secure cloud hosting providers and analytics tools to operate our servers and monitor app performance.

No Cross-User Aggregation: Your e-commerce data is strictly siloed. We never aggregate your shop data with other users to power market research, trend-spotting, or competitor analysis tools.

4. Data Retention and Deletion

We retain your personal data only for as long as is necessary for the purposes set out in this Privacy Policy.

Account Data: Maintained as long as your account is active. Upon account deletion, your personal information is permanently removed from our active systems.

Automated Asset Cleanup: To maintain system efficiency and protect user privacy, temporary assets (such as AI-generated images stored on Cloudflare) and canceled publishing jobs are subject to automated pruning. Items removed from your dashboard are permanently hard-deleted from our databases and storage buckets within 14 days.

Revoking Access: You may revoke our access to your Etsy, Shopify, or Pinterest accounts at any time directly through those respective platforms. Doing so will instantly sever our connection. Upon revocation, we will promptly and permanently delete your associated OAuth tokens and synced shop data from our active databases.

5. Cookies and Tracking Technologies

We use cookies and similar tracking technologies to track activity on our Service and hold certain information.

Essential Cookies: Required for session management, user authentication, and ensuring the Postier dashboard functions correctly.

Analytics Cookies: Used to track how users navigate the platform so we can improve the user interface.

You can instruct your browser to refuse all cookies; however, doing so may prevent you from logging into your Postier account.

6. Your Data Protection Rights

Depending on your location (such as the European Economic Area or California), you may have the following legal rights regarding your personal data:

• The right to access: You can request copies of your personal data.
• The right to rectification: You can request that we correct any inaccurate or incomplete information.
• The right to erasure: You can request that we erase your personal data, under certain conditions.
• The right to restrict or object to processing: You can object to how we use your data or request that we limit our processing activities.
• The right to data portability: You can request that we transfer the data we have collected to another organization, or directly to you.

To exercise any of these rights, please contact our support team. We will respond to your request within the timeframe required by applicable law.

7. Security of Your Information

The security of your data is a priority. We implement industry-standard security measures, including SSL encryption and secure API token handling, to protect your information from unauthorized access, alteration, or destruction. However, no method of transmission over the Internet or method of electronic storage is 100% secure, and we cannot guarantee absolute security.

8. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Last Updated" date at the top of this document. We may also notify active users via email of any material changes.

Strictly Necessary (Essential) Cookies: These are required for the operation of the Service.

• Publish excessive, duplicative, or spam-like content that degrades the experience of Pinterest end users.

5. API Rate Limits and Enforcement

Your use of the Service is subject to the rate limits imposed by the Pinterest API. If your account triggers Pinterest's automated spam filters or API throttling due to excessive publishing volume, Postier will automatically delay or cancel your scheduled queue to protect your account standing.

At Holt Base LLC ("we," "us," or "our"), we understand that your Etsy shop is the lifeblood of your business.

2. What Data We Access

When you authorize Postier to connect to your Etsy shop via OAuth 2.0 and we never see, request, or store the user’s Etsy password. We request read-only access to specific scopes required to automate your Pinterest marketing. We exclusively access:

Public Shop Data: Your shop name and basic profile information.

Listing Data: Your active product listings, including titles, descriptions, pricing, tags, and URLs.

Listing Images: The product photos associated with your active listings.

What we DO NOT access: We do not request, access, or store any sensitive buyer data, order histories, financial ledgers, customer messages, or shipping addresses. Our application has no requirement or ability to alter, delete, or manage your Etsy shop inventory.

3. How We Use Your Etsy Data

Your Etsy data is strictly used to provide the Postier automation service. Specifically:

• We use your listing titles, descriptions, and images to our AI generation partners (such as OpenAI) to create optimized marketing copy and visual assets for Pinterest.
• Data sent to our AI partners (such as OpenAI) is used via secure API for inference only to generate your requested outputs. We strictly prohibit our AI partners from using your Etsy listing data, images, or descriptions to train their machine learning models.
• We use your listing URLs to ensure the pins we publish successfully route traffic back to your specific Etsy products.

4. Data Security and Retention

We treat your Etsy data with the highest level of security.

Storage: We securely store your Etsy OAuth tokens and shop metadata in our encrypted database.

Retention: We only retain your Etsy listing data for as long as it is actively scheduled in your Postier pipelines. Once a Pinterest campaign finishes or is deleted, any temporary assets associated with those listings are automatically pruned from our active servers within 14 days.

Third-Party Sharing: Your Etsy data is never sold to third parties. It is only transmitted to authorized infrastructure partners (like OpenAI and Cloudflare) strictly for the purpose of generating your requested marketing materials.

No Cross-User Aggregation: Your shop data is strictly siloed. We never aggregate your listing data, sales data, or tags with other users, and we do not use your data to power market research, competitor analysis, or trend-spotting features for other sellers.

5. Revoking Access

You remain in complete control of your Etsy data. You can disconnect Postier at any time in two ways:

From Postier: By deleting your store connection in the Postier dashboard.

From Etsy: By logging into your Etsy account, navigating to Account Settings > Apps, and clicking "Revoke" next to the Postier application.

Upon revoking access or deleting your Postier account, we immediately and permanently delete your Etsy OAuth tokens. All previously synced listing data, metadata, and cached images associated with your shop will be fully purged from our active databases.
