Privacy Policy

Overview

Paperly is a Google Docs Add-on built by Presdin Works LLC. We take a minimal approach to data: your document content is never stored — it is processed in memory for the requested feature and immediately discarded.

Permissions Paperly requests

Paperly requests the following Google permissions:

• Read document content — required to run formatting checks, AI rubric review, plagiarism scans, and paraphrase suggestions.
• Modify document content — required to highlight flagged issues and apply auto-fixes inside your document.
• Display sidebar UI — required to show the Paperly sidebar inside Google Docs.
• Your email address (Google identity) — required to identify your account, manage your subscription status, and track free run usage.

Live Formatting Checks

All eight formatting checks (double spaces, contractions, duplicate words, long sentences, font size, font family, line spacing, and missing sections) run entirely inside the Google Docs sidebar. Your document text is never sent to our servers for this feature. No account or internet connection is required.

AI Rubric Check

When you run an AI Rubric Check, the following data is sent over HTTPS to our backend:

• Your full document text
• The criteria you entered for evaluation

This data is forwarded to the Anthropic Claude API to generate the rubric evaluation. It is not stored after the response is returned.

Plagiarism Scan

When you run a Plagiarism Scan, your full document text is sent over HTTPS to our backend, which compares it against public academic databases (OpenAlex, CrossRef, and arXiv). Your text is not submitted to those databases in a way that makes it publicly accessible. The text is discarded after the scan completes.

Paraphrase Suggestions

When you request a paraphrase suggestion for a flagged sentence, that sentence (and a small amount of surrounding context) is sent over HTTPS to our backend and forwarded to the Anthropic Claude API to generate an alternative phrasing. The text is not stored after the response is returned.

Account and subscription data

Paperly uses your Google identity (email address) to:

• Identify your account and manage your subscription status
• Track your remaining free runs for AI and plagiarism features
• Link your account to a Stripe subscription if you subscribe to Paperly Pro

We do not sell, rent, or share your email address with any third party except as described in this policy. It is never used for marketing or advertising.
