Privacy at a Glance

Introduction

Welcome to our privacy policy

Thank you for choosing PrivacyFill — the temporary email and identity generator that protects your real inbox from spam and unwanted newsletters. This Privacy Policy explains how we handle your information when you use our Chrome extension.

We built PrivacyFill with a fundamental principle: a privacy tool should itself be private. Your generated identities, temporary emails, and preferences stay on your device. We never see, store, or transmit your personal data.

The Irony We Avoid: It would be counterproductive for a privacy tool to collect your data. That's why PrivacyFill operates entirely in your browser, with no servers storing your information.

How PrivacyFill Works

Understanding our service

PrivacyFill helps you maintain online privacy by generating temporary identities:

  • Temporary Email Generation — We create real, working disposable email addresses through third-party temporary email services
  • Identity Generation — Random names, usernames, and passwords are generated locally in your browser
  • Inbox Access — You can receive and read emails sent to your temporary addresses directly in the extension
  • Auto-Fill — The extension can automatically populate signup forms with your generated identity

Important: Temporary emails are designed for short-term use. They may expire after a period of inactivity. Do not use them for accounts you need long-term access to.

Data Stored Locally

Information saved on your device only

The following data is stored locally on your device using Chrome's secure storage API:

Data Type Purpose Storage Shared
Generated Names
Display & auto-fill Local Never
Temp Email Addresses
Inbox access Local To API*
Generated Passwords

Generated Usernames

*Note on Temp Emails: To check your inbox, the extension sends requests to the temporary email service's API. This is necessary to retrieve emails but only involves the temporary address — never your real email or personal data.

Data We DON'T Collect

What we never access or store

We believe in absolute minimal data collection. Here's what we never collect:

  • Your Real Email Address — We never ask for or access your personal email
  • Your Real Name — We don't know who you are
  • Browsing History — We don't track which websites you visit
  • Form Data You Enter — We only fill forms, never read what you type
  • IP Address — We don't log or store your IP
  • Device Fingerprints — No hardware IDs or device identification
  • Analytics or Telemetry — No usage tracking, no analytics services
  • Cookies — The extension doesn't use cookies

Third-Party Services

External services we interact with

PrivacyFill interacts with the following external services to provide its functionality:

Temporary Email Providers

We use third-party temporary email services to generate working disposable email addresses and retrieve incoming messages. These services only receive the temporary email address — never your real identity. Common providers include Mail.tm, Guerrilla Mail, or similar services.

Chrome Web Store

Premium purchases are processed securely through Google's Chrome Web Store payment system. We never receive or store your payment details — all transactions are handled by Google.

No Hidden Services: We don't use Google Analytics, Facebook Pixel, advertising networks, or any data brokers. The only external calls are to temporary email APIs and (optionally) Chrome Web Store for payments.

How Auto-Fill Works

Form filling explained

Understanding how our auto-fill feature accesses web pages:

  • Page Access — The extension needs permission to interact with web pages to fill forms
  • Form Detection — We detect input fields by their type, name, and placeholder text
  • Data Injection — Only your generated identity data is inserted into forms
  • No Reading — We don't read, store, or transmit any data you type into forms
  • User Initiated — Auto-fill only happens when you click the button

Security Note: The auto-fill feature runs entirely in your browser. Form data goes directly from your browser to the website — we're never in the middle.

Data Storage & Security

How your data is protected

Your data security is ensured through multiple layers:

  • Local-Only Storage — All data is stored using Chrome's chrome.storage.local API
  • Browser Sandboxing — Benefits from Chrome's built-in security isolation
  • No Server Storage — We don't operate servers that store user data
  • No Backups — Since we don't have your data, there's nothing to leak
  • Automatic Cleanup — Uninstalling the extension removes all local data

Generated passwords are stored locally for your convenience. For maximum security, consider using a dedicated password manager for important accounts.

Your Rights & Controls

You're in complete control

You have full control over your data at all times:

View Data

See all generated identities and settings in the extension popup

Delete Identities

Remove individual identities or clear all data with one click

Reset Extension

Clear all data and start fresh anytime

Uninstall

Removing the extension deletes all data permanently

Premium & Payments

How premium purchases work

When you purchase premium features:

  • Payment Processing — All payments are handled exclusively by Google through the Chrome Web Store
  • No Payment Data — We never receive, see, or store your credit card information
  • License Verification — Premium status is verified through Chrome's licensing API
  • One-Time Payment — No subscriptions, no recurring fees — pay once, use forever
  • No Account Required — Premium is tied to your Chrome profile, not a PrivacyFill account

Free Version

What's included for free

The free version includes:

  • 10 Generations Per Month — Create up to 10 temporary identities monthly
  • Full Feature Access — Temporary emails, inbox, and auto-fill all work in free tier
  • Local Counter — Usage is tracked locally on your device, not on our servers
  • Monthly Reset — Counter resets automatically each month

Free Forever: The free version will always exist. Premium is optional and simply removes the monthly limit while supporting development.

Children's Privacy

Protection for younger users

PrivacyFill is designed for users aged 13 and older. Since we don't collect any personal information from any users, we inherently don't collect data from children. However, we recommend parental guidance for users under 18.

Changes to This Policy

How we handle updates

We may update this Privacy Policy from time to time. When we make changes:

  • Date Updated — The "Last Updated" date at the top will reflect the change
  • Material Changes — Significant changes will be noted in extension update notes
  • Continued Use — Using the extension after changes constitutes acceptance

We encourage you to review this policy periodically. Our commitment to not collecting your personal data will not change.
