Your email never leaves your computer.
No asterisk. Unsubscribe Me has no cloud backend, no servers, and no way to read your inbox — because the entire app runs on your own machine.
“Never hand a company you've never met the keys to your inbox.” That belief is the whole reason this app exists — and why it works the way it does.
The one principle
Unsubscribe Me is designed around a single idea: everything happens on your own computer. There is no cloud backend, no analytics service, no advertising network, and no telemetry. Your email content, message metadata, sign-in tokens, derived statistics, and any screenshots of automated unsubscribe pages are all stored exclusively on your local device.
What stays on your device — always
- Email content & metadata — read in memory to find unsubscribe links, never uploaded. Attachments are never opened.
- OAuth tokens — the read/modify tokens for your accounts live only in your operating system's protected app storage.
- Subscription history & statuses — kept in a local SQLite database on your disk.
- Confirmation screenshots — saved locally as proof an unsubscribe went through.
- Your statistics — computed on-device; we never see a single number.
The only four things that ever touch the network
Each one is an action you took, sent to a destination you chose. None of it ever comes to us.
- 1 · OAuth sign-in with Google, Microsoft, or your provider, to prove you own the account.
- 2 · Mailbox reads & edits through the official Gmail / Microsoft Graph / IMAP APIs — to scan, label, and archive your own mail.
- 3 · The unsubscribe request sent to a sender's published opt-out endpoint when you click unsubscribe.
- 4 · The opt-out email sent from your own account to a sender's mailto: address, when that's the only method available.
What never happens
- No cloud backend means there is no “your data in transit to us.”
- No analytics, telemetry, or crash reporting.
- No AI or machine-learning models — unsubscribe detection is deterministic pattern matching and browser automation.
- No profiling, advertising, or selling of data.
- No human — including us — can read your email.
Why “local” is safer than “trusted”
Cloud unsubscribe services ask you to grant a remote server standing access to your entire mailbox. You're trusting that the company is honest today, stays honest tomorrow, never gets breached, and never quietly changes its terms. With Unsubscribe Me there's nothing to trust: the data simply never leaves, and there's no server that could be compromised to expose it.
Security details
- All network connections use TLS 1.2+.
- The macOS app is signed with an Apple Developer ID and notarized by Apple, with the hardened runtime enabled.
- Tokens and the local database sit inside your OS-protected application data directory.
Short version: if a feature would require sending your email somewhere we could read it, we don't ship that feature.
