Security & Privacy at MailMop
Cleaning up your inbox shouldn't mean handing it to a stranger. MailMop was built so you never have to: your Gmail is analyzed in your browser, and your email contents never touch our servers.
Your inbox is analyzed in your browser
MailMop connects your browser straight to Gmail. Sorting, counting, and grouping your mail by sender all happens on your own device. There is no MailMop server in the middle reading your email.
Email contents never touch our servers
Messages, subject lines, and attachments are not uploaded to MailMop. When MailMop reads an email to find a working unsubscribe link, that happens in your browser too.
Audited by Google's security program
Apps that ask for restricted Gmail permissions must pass Google's Cloud Application Security Assessment (CASA). MailMop passed it.
Open source, so you can check
Most inbox cleaners ask you to trust a black box. MailMop is open source on GitHub, so you, a security researcher, or a curious friend can check how it handles your data.
No ads. No selling data.
Some "free" inbox tools have paid for themselves by selling insights from your purchase receipts. MailMop is paid for by Pro subscriptions, so your inbox is never the product.
You stay in control
Nothing happens to your mail until you click. You can disconnect MailMop in one click, or revoke its access from your Google Account at any time.
How MailMop is different
Most inbox cleaners work by pulling your mail onto their own servers and processing it there. That copy can be kept, breached, subpoenaed, or quietly turned into a product. In 2017, Unroll.Me users learned that their e-receipts had been used to sell market research about Lyft to Uber.
MailMop takes the opposite approach. Your browser does the work, Gmail stays the only place your email lives, and there's no server-side copy of your inbox to leak or sell.
The permissions MailMop asks for, and why
When you connect, Google will tell you MailMop wants full access to Gmail. Permanently deleting mail, blocking senders, and creating filters all require that permission, so we ask for it once instead of breaking cleanup into a dozen prompts. That access is used from your own browser, only for the actions you choose.

No. MailMop runs in your browser and talks to Gmail directly from your device. Your email contents are never sent to or stored on MailMop's servers.
Why does MailMop ask for full Gmail access?
Permanently deleting email, blocking senders, and creating filters all require Gmail's full-access permission, so MailMop asks for it up front. That access is used from your own browser, only for the actions you choose.
Has MailMop been security audited?
Yes. MailMop passed Google's Cloud Application Security Assessment (CASA), the independent security review Google requires of apps that use restricted Gmail permissions.
