Your Data is Yours — How EmailSlim Uses Email Access

Last Updated: January 15, 2024

What We Access

We only analyze metadata (sender, date, subject length). We do NOT read your email content.

EmailSlim processes email metadata through Google and Microsoft email APIs to show you storage usage patterns. We never access, read, store, or analyze the actual content of your emails—only the information needed to help you understand what's using your storage space.

Why We Need Permissions

OAuth is required to scan metadata and perform deletions you approve.

When you sign in with Google or Microsoft, you're using OAuth—a secure way to grant EmailSlim permission to access your email account. We request two specific permissions (same for both providers):

Read email metadata
This lets us see sender, date, size, and labels—but NOT the content of your emails
Modify emails (when you approve)
This lets us move emails to Trash (Gmail) or Deleted Items (Outlook) when you explicitly request deletion

These are the minimum permissions needed to show you storage usage and help you delete emails. We don't request permission to read your email content, and we never access it.

Deletions Explained

Deletions go to Trash (Gmail) or Deleted Items (Outlook) — you can recover them.

When you choose to delete emails through EmailSlim, here's exactly what happens:

1. You review what will be deleted
EmailSlim shows you which emails will be deleted before any action is taken
2. You explicitly approve the deletion
Nothing happens until you click the delete button and confirm
3. Emails go to Trash or Deleted Items
Gmail: moved to Trash. Outlook/Hotmail/Microsoft 365: moved to Deleted Items. Not permanently deleted.
4. You can recover them
Gmail: 30 days in Trash. Outlook: recovery period varies by account; you can restore from Deleted Items.

Important: EmailSlim never permanently deletes emails. All deletions go through your provider's Trash or Deleted Items, where you can recover them within the provider's retention period.

Control & Revocation

You can remove access via Google or Microsoft account settings anytime.

You're always in control. You can revoke EmailSlim's access to your email account at any time:

Through Google Account Settings
Go to your Google Account → Security → Third-party apps → Remove EmailSlim access
Through Microsoft Account Settings
Go to account.microsoft.com → Privacy → Apps and services → Remove EmailSlim access
Through EmailSlim Settings
You can disconnect your email account from within EmailSlim's settings page
Delete Your Account
You can delete your EmailSlim account at any time, which removes all stored data

When you revoke access, EmailSlim immediately stops accessing your email account. Any metadata we've already processed remains stored until you delete your account, but we stop accessing new data as soon as you revoke permission.

Common Questions

Can we read your emails?

No. We never read your email content. We only access metadata (sender, date, subject length, size). We don't have permission to read email content, and we never request it.

Do we share data?

No. We don't sell, rent, or trade your personal information. We only share limited data with trusted service providers (like Google and Microsoft for email API access, and Stripe for payments) as necessary to provide our service. Your email metadata is never shared with marketers, advertisers, or other services.

Can we delete emails without your permission?

No. All deletions require your explicit approval. We never delete anything automatically without your consent. You review what will be deleted, then explicitly approve the action. All deleted emails go to Trash (Gmail) or Deleted Items (Outlook) first, where they can be recovered within the provider's retention period.

Can you remove access anytime?

Yes. You can revoke EmailSlim's access to your email account at any time through Google Account settings or Microsoft account settings. When you remove access, we immediately stop accessing your account. You can also delete your EmailSlim account at any time, which removes all stored data.
