Who We Are

Pipewriter is built by writers, for writers. “We” are a small team… of one (it’s a-me, Ivan) who believes that copywriters, UX writers, and content strategists deserve product development tools as sophisticated as those used by designers and developers. After all, great products start with great words. Even movie films have screenplays, after all.

Company Details: Pipewriter OÜ, registered at Sepapaja 6, Tallinn 15551, Estonia, reg. no. 14904870. We’re incorporated in Estonia but serve writers worldwide who want to create better documents in Google Docs.

What Pipewriter Does

Pipewriter is a Google Docs add-on that transforms your familiar writing environment into a wireframing and design tool. Think of it as giving Google Docs superpowers for creating professional website copy decks, email templates, and other structured content that looks like it came from a design agency.

Our add-on provides pre-made elements (tables, layouts, components) that you can copy or insert into your documents with one click. We also offer premium templates - standalone Google Docs with professional formatting and wireframe structures that you can purchase and customize for your projects.

Information We Collect

How Our Add-On Works

Here’s the technical bit: our add-on uses Google’s most restrictive document permissions to help you create professional wireframes directly in Google Docs. When you open our sidebar and insert elements, we’re using programmatic table generation to create wireframe components at your cursor position - like having a design assistant that builds tables, applies formatting, and structures content according to professional UX standards.

We also provide HTML conversion and AI prompt features that process your document content, but crucially, this processing happens entirely within Google’s infrastructure using Google Apps Script. When you use our HTML export feature or insert AI prompts, your document content is processed locally within Google’s servers and never transmitted to our external servers. The conversion logic runs as part of Google’s platform, reads your document headings and text, transforms them according to our formatting rules, and either inserts the results back into your document or copies them to your clipboard - all without your content ever leaving Google’s secure environment.

Important clarification: We can only access the specific document you’re actively working on when our add-on is open. We cannot and do not read your other documents or access your document content for any purpose other than the specific features you activate.

Google OAuth Permissions Explained

Our add-on requests only two specific Google permissions - the minimum necessary to provide our wireframing functionality:

Current Document Only (https://www.googleapis.com/auth/documents.currentonly): This is Google’s most restrictive document permission, allowing us to modify only the document you’re actively working on. We use this to:

Insert wireframe elements (tables, layouts, components) at your cursor position
Apply professional formatting and styling to create clean wireframes
Change background colors and table formatting for design purposes
Transform selected content into HTML for AI integrations
Update text styles and headings for consistent wireframe hierarchy

This scope is specifically designed to be privacy-protective - it cannot access any of your other Google Docs, only the one you’re currently editing with our add-on open.

Sidebar Interface (https://www.googleapis.com/auth/script.container.ui): This displays our element picker, AI tools, color customization, and other features in Google Docs’ sidebar.

Technical Reality: Our add-on operates through Google Apps Script, which means all document processing happens within Google’s secure infrastructure. We generate wireframe elements programmatically using Google’s native table and formatting APIs. When you use features like HTML conversion, all processing occurs locally within Google’s servers using your document’s existing content - your data never leaves Google’s secure environment.

Data Flow Guarantee: Your document content never leaves Google’s infrastructure when using our HTML conversion, prompt insertion, or any other processing features. All text analysis, formatting, and content generation happens through Google Apps Script running within Google’s secure environment, ensuring your confidential content remains within Google’s privacy and security boundaries at all times.

Limited Use of User Data and AI/ML Policy Compliance

Important: Pipewriter’s use of information received from Google APIs adheres to

Google API Services User Data Policy, including the Limited Use requirements

The use of raw or derived user data received from Workspace APIs will adhere to the Google User Data Policy, including the Limited Use requirements.

Specifically, we comply with Google’s Limited Use policy for:

Workspace API User Data — We only access the current document you're editing and use that data solely to provide the wireframing features you explicitly request
Photos API User Data — While we don't currently use Photos APIs, any future integration will comply with these same limited use requirements

What this means for you: We cannot and will not use your Google Docs content for any purpose beyond providing the specific wireframing and formatting features you activate. We don’t analyze your writing for advertising, don’t share it with third parties, and don’t use it to train AI models or for any other secondary purposes.

AI and Machine Learning Policy

Clear Statement: Pipewriter does not use user data to train, develop, or improve any AI or machine learning models - neither personalized nor generalized.

Our “AI Features” Explained

When we mention “AI features” in our app, we’re referring to our prompt library system - not actual AI processing. Here’s exactly what this means:

Prompt Templates Only: Our “AI prompts” are pre-written text templates that you can insert into your documents. Think of them as professional writing prompts optimized for different tasks (like “polish this copy” or “write a feature description”). These are just text templates - no AI processing occurs.

No AI Processing: We do not run any artificial intelligence or machine learning processing on your document content. We don’t send your content to ChatGPT, Claude, Gemini, or any other AI service. We simply provide you with professionally crafted prompts that you can use with whatever AI tools you choose.

Your Choice of AI: When you use our prompt templates, you copy the prompt text and use it with your preferred AI service (ChatGPT, Claude, etc.) entirely outside of our platform. This gives you full control over which AI services (if any) you use and how you use them.

No Data Retention for AI: We do not collect, store, or retain any user data for the purpose of training AI models. As outlined in Google’s API policy protections for generative AI, we are prohibited from using Workspace user data to train non-personalized AI/ML models, and we fully comply with this policy.

Future AI Features: Should we ever develop actual AI processing features (which would require additional permissions and explicit user consent), we will update this policy with clear explanations and maintain full compliance with Google’s Limited Use requirements.

Usage and Preferences

We collect information about how you use our add-on to make it better. This includes which elements you insert most often, your preferred themes (light or dark), and any customization settings you choose.

Personal Prompt Library: To get you started quickly, we provide a curated set of default AI prompts for common writing tasks (like “polish copy” or “write a feature description”). These starter prompts are copied to your personal prompt library when you first sign up, where you can edit them, create new ones, or delete any you don’t need. Your prompt library is stored securely in your individual account space - think of it like having your own private collection of writing templates that travels with you across devices.

We designed this system so you can build a personalized set of AI prompts that match your writing style and client needs, starting from our professionally crafted defaults. Your custom prompts remain in your private account and are only used when you explicitly choose to apply them to your documents.

If you purchase our premium templates, we keep records of your purchases and download activity. For subscription users, we track usage patterns to ensure our service remains fast and reliable.

Automatic Information

Like most web services, we automatically collect some technical information including your device type, browser version, IP address, and how you interact with our add-on. This helps us fix bugs, improve performance, and understand which features are most valuable to our users.

How We Use Your Information

We use the information we collect to provide and improve Pipewriter. Specifically, we use it to process your payments through Stripe (our payment processor), provide customer support, send important updates about the service, and develop new features that writers actually want.

For subscription users, we use usage data to optimize performance and ensure fair access to our servers. For template customers, we use purchase history to recommend relevant new templates and bundles.

We may also use your information to send occasional marketing communications about new templates or features, but you can opt out of these at any time. We’ll never send you spam or sell your email to other companies.

Information Sharing

We don’t sell your personal information, period. That would be pretty terrible, and we’re not in the business of being terrible.

We do share information with a few trusted service providers who help us run Pipewriter. Stripe processes our payments and has their own robust privacy protections. Google provides our authentication and document services. Firebase (part of Google Cloud) stores our user data securely.

We may also share information if required by law or to protect our rights, but we’ll fight any unreasonable requests and notify you when legally permitted.

Data Storage and Security

Your data is stored securely using Google’s Firebase platform, which provides enterprise-grade security and encryption. Payment information is handled exclusively by Stripe - we never see or store your credit card details.

Since we’re a small team, we take security seriously precisely because we can’t afford not to. We implement industry-standard security measures and regularly update our systems. However, no internet service is 100% secure, so we can’t guarantee absolute security (nobody can, despite what they might claim in their marketing).

Your Rights and Control

You have significant control over your information. You can access, correct, or delete your personal information at any time by contacting us. You can also export your custom prompts and settings if you want to keep a local backup.

If you’re in the European Union, you have additional rights under GDPR including the right to data portability and the right to restrict processing. If you’re in California, you have rights under CCPA including the right to know what personal information we collect and the right to delete it.

You can also revoke our add-on’s access to your Google account at any time through your Google account settings. This will disable the add-on but won’t delete your Pipewriter account or purchase history.

Templates and Content Ownership

When you purchase our premium templates, you’re buying the right to use them in your projects. The templates themselves remain our intellectual property, but any content you add to them is yours. You can use our templates for client work, internal projects, or personal use, but you can’t resell or redistribute the templates themselves.

Any custom prompts, settings, or modifications you create within Pipewriter belong to you. We may analyze usage patterns across all users to improve our service, but we don’t read individual custom content or share it with anyone.

International Users and Data Transfers

Pipewriter serves writers worldwide from our base in Estonia. Your information may be processed in the United States (where Google and Stripe operate), the European Union (where we’re based), and other countries where our service providers operate.

We ensure that any international data transfers comply with applicable privacy laws including GDPR Article 46 safeguards. Essentially, we only work with service providers who meet European privacy standards regardless of where they’re located.

Changes and Updates

We may update this privacy policy as our service evolves. We’ll notify you of material changes by email and by posting the updated policy on our website. The “last updated” date at the top tells you when the policy was last modified.

If we make significant changes that affect how we use your information, we’ll give you the opportunity to review the changes before they take effect.

We typically respond within 24 hours during business days, though sometimes it takes a bit longer when I’m deep in code or dealing with the inevitable challenges of being a solo developer trying to build something useful for fellow writers.

For urgent privacy-related concerns, please mark your email as “Privacy - Urgent” and we’ll prioritize it accordingly.

This privacy policy is governed by Estonian law and EU privacy regulations. If you’re a writer who’s read this far, you probably understand the importance of clear, honest communication - which is exactly what we’re aiming for here.
