Privacy Policy

Last updated: March 3, 2025

1. What We Do

Metadata Cleaner is a Google Workspace Add-on that removes hidden metadata (author names, GPS coordinates, timestamps, edit history, etc.) from files in Gmail and Google Drive.

2. How File Processing Works

This is the most important part of our privacy policy:

• Your files never leave Google's servers. When you use Metadata Cleaner in Gmail, the add-on reads your draft attachments using Google's Apps Script APIs, processes them within Google's infrastructure, and saves the cleaned versions back — all within Google's servers.
• Our servers never see your files. Our backend server handles only license verification and usage counting. It receives your email address and the number of files processed — never file contents, names, or any data from inside your files.
• No third-party access. Your files are not sent to any external services, APIs, or servers outside of Google's infrastructure.

3. What Data We Collect

We collect the minimum data necessary to operate the service:

• Email address — To identify your account, manage your subscription, and count monthly usage.
• Usage count — The number of files you've cleaned per month (e.g., "15 files in March 2025"). We never store file names, types, or contents.
• Subscription data — Your plan type and Stripe customer ID for billing purposes.

4. What Data We Do NOT Collect

• File contents, names, or metadata
• Email contents, subjects, or recipients
• Browsing history or activity outside the add-on
• Contacts or calendar data
• Any data from other Google Workspace apps

5. Google Workspace Permissions

The add-on requests the following Google API scopes:

• Gmail read/compose/modify — To read attachments from drafts, create cleaned versions, and send emails.
• Drive access — To read and update files you select for metadata cleaning in Google Drive.
• User email — To identify your account for license and usage tracking.

These permissions are used solely for the metadata cleaning functionality described above.

6. Payment Processing

Payments are processed by Stripe. We do not store credit card numbers or payment details on our servers. Stripe's privacy policy governs the handling of your payment information.

7. Data Storage & Security

• Account and usage data is stored on Appwrite Cloud (hosted in the EU).
• All communications are encrypted via HTTPS/TLS.
• We use API key authentication between the add-on and our backend.
• Dashboard authentication uses one-time magic links (no passwords stored).

8. Data Retention

• Usage counters are reset monthly.
• Account data is retained while you have an active account.
• If you uninstall the add-on and request deletion, we will remove all your data within 30 days.

9. Your Rights

You can:

• Request a copy of all data we store about you
• Request deletion of your data
• Uninstall the add-on at any time from Google Workspace Marketplace

To exercise these rights, contact us at support@metacleaner.site.

10. Changes

We may update this policy from time to time. Significant changes will be communicated through the add-on or via email.
