Simpler Threads privacy policy
What the Simpler Threads extension reads, stores and sends. Short version: it reads the Gmail thread you have open, keeps one on/off switch, and sends nothing.
Last updated: November 11, 2026
Simpler Threads is a browser extension for Chrome and Firefox that shows long Gmail reply chains as a clean list of messages. This policy explains what data it handles.
Short version
- The extension does not collect, transmit, sell or share any data.
- It has no server, no account, no analytics and no ads.
- The only thing it stores is an on/off switch, in your browser.
Where it runs
The extension only has access to https://mail.google.com. There it reads the Gmail conversation you have open, from the page, and rebuilds it as a list locally in your browser. It does not run on any other site.
It does not use the Gmail API or OAuth and never asks to sign in to your Google account. It only sees what Gmail already shows in your tab.
Permissions
storage: to remember whether the extension is on or off.- Host access to
mail.google.com: to read the conversation you have open.
What it stores
One setting, the on/off switch, in the browser’s extension storage (storage.local) on your device. Your email is not stored. Uninstalling the extension deletes the setting.
What leaves your browser
Nothing. The extension makes no network requests of its own. Images inside an email load the same way Gmail loads them.
Sharing and sale
The developer receives no data, so there is nothing to share or sell. Your data is not used for advertising, credit decisions or anything unrelated to showing your Gmail threads.
The use of information received from Google APIs will adhere to the Chrome Web Store User Data Policy, including the Limited Use requirements.
Changes
If this policy changes, the new version will be posted at this address with a new “Last updated” date.
