Privacy Policy
Last updated June 25, 2026
Short version: Cortex keeps your data in your own browser. We do not run a server that collects your browsing or your posts.
What Cortex stores
- Your settings: which networks you have enabled and your preferences, saved locally in your browser's storage.
- Account tokens: when you connect a network, the access token that network gives back is stored locally so you can post without signing in every time.
- Share history: a local record of what you shared, so the undo and history features work. This stays on your device.
What Cortex does not do
- It does not send your browsing history to us.
- It does not sell or share your personal data with third parties for advertising.
- It does not track you across sites.
Permissions and why
Cortex requests access to the current tab and page content so the menu can appear where you click and can read the link, image, or text you want to share. It requests identity and network permissions only to connect the accounts you choose and to share on your behalf.
Third-party networks
When you share to a network, your content is sent to that network through its official interface and is then governed by that network's own privacy policy. We encourage you to review the policies of the networks you connect.
Data retention and removal
Because data is stored locally, you can clear it at any time by disconnecting a network in settings or by removing the Extension, which deletes its local storage.
Children
Cortex is not directed to children under 13 and we do not knowingly collect data from them.
Changes
If this policy changes, we will update the date above. Material changes will be reflected on this page.
