How to stop data leaks in Gemini
Gemini is one click away for every Google Workspace user. That convenience means spreadsheets of customer data, internal docs, and Drive content flow into prompts without any security review. LeakSnitch watches this surface locally so sensitive data never reaches Gemini.
Short answer
Gemini is an AI platform from Google. LeakSnitch scans text inputs, file uploads, and drag and drop content on gemini.google.com with publicly auditable patterns, and blocks or redacts sensitive data before the request is submitted. Detection runs entirely on the device and takes under 50 milliseconds.
The most common Gemini leaks
- Google Cloud API keys and OAuth client secrets

Frequently asked questions
Does LeakSnitch work on Gemini for free?
Yes. The free individual tier includes full detection on Gemini and every other supported platform, with no limits on the number of AI tools you use.
Can Gemini read data LeakSnitch blocks?
No. LeakSnitch intercepts the submission before it is sent, so blocked or redacted data never reaches Gemini, its provider, or third parties.
Is Gemini usage monitored without permission?
LeakSnitch only activates on the text you type into supported AI platforms. It never reads browsing history, other sites, or content outside the AI page. In enterprise deployments, admins set the policy and users see every detection in the modal.
