QuickDef (“we”, “our”, or “us”) operates the QuickDef Chrome extension and related web services (“the Service”). This Privacy Policy explains what information is collected, how it is used, and your rights.

QuickDef is designed to minimize data collection and operate with limited, user-initiated processing only.

1. Overview

QuickDef provides instant, learner-friendly English word definitions when users double-click words on web pages or PDF documents. A free tier is available without an account. Premium features require account registration and a paid subscription.

The Service only processes information necessary to deliver dictionary functionality, manage your account, and process payments.

2. Information We Collect

A. User-Selected Text (Dictionary Requests)

When you request a definition:

The selected word
A short surrounding sentence (for context)

may be securely transmitted to our backend and AI provider to generate a learner-friendly definition.

We do not:

Transmit full web pages
Transmit full PDF documents
Monitor browsing activity
Automatically collect page content

Processing occurs only when you explicitly request a definition.

B. Account Information

When you create an account or upgrade to Premium, we collect and store:

Email address
Subscription tier (free or premium)
Subscription plan (monthly or yearly)
Subscription expiry date

This data is stored securely in our database (Supabase) and is used solely to authenticate your account and enforce subscription entitlements in the extension.

C. Payment Information

Payments are processed by licensed third-party payment processors. We do not store your card number, bank account details, or other sensitive financial information.

Card payments (USD) are handled by Polar (polar.sh)
IDR payments are handled by Xendit

We retain a payment record (external transaction ID, plan, amount, status, and timestamps) in our database for billing verification and support purposes.

D. Saved Words

If you use the Save Word or flashcard features, saved words and their definitions are synced to your account in our database so they are available across devices. Free accounts can save up to 50 words; Premium accounts have no limit.

E. Technical Error Logs

We may collect limited, anonymous technical error logs strictly related to service reliability (such as failed definition requests).

These logs do not include:

Browsing history
Full page content
PDF documents

3. AI Processing

QuickDef uses AI services to generate simplified, learner-friendly definitions.

When AI processing occurs:

Only the selected word and short context are transmitted
The data is used solely to generate the requested definition
No full documents are transmitted
The data is not used for advertising

AI processing is strictly limited to dictionary functionality.

4. How Information Is Used

We use information to:

Provide instant word definitions
Authenticate your account and enforce subscription limits
Enable saved words and flashcard features with cross-device sync
Process and verify payments
Improve definition quality and service reliability
Communicate updates (only if you opted in)

5. Data Storage

Account data (email, subscription status) is stored securely in Supabase
Saved words and definitions are synced to your account in our database
Payment records are stored for billing verification and support
Cached definitions may be stored temporarily to reduce repeated AI requests

6. Third-Party Services

QuickDef uses the following third-party services:

Supabase — account and data storage
Polar — card payment processing (USD)
Xendit — local payment processing (IDR)
AI provider — definition generation
Vercel — hosting and infrastructure

Each service is used only to operate the Service and is required to follow applicable data protection rules.

7. Data Retention

Saved words remain until you delete them
Account data can be deleted upon request
Payment records may be retained for legal and accounting purposes
Communication emails can be unsubscribed at any time

8. Your Rights
