The Problem: Cloud-Based Tools Upload Your Content
What Happens When You Use Cloud Tools:
Your Content is Uploaded
Files, text, images, data - everything sent to third-party servers
Processed Remotely
AI models and processing happen on company servers, not your computer
Stored Indefinitely
Content may be stored temporarily or permanently on cloud servers
Subject to Terms of Service
Your content is governed by their privacy policy, not yours
Potential AI Training Data
Some services may use your content to train AI models
Data Breach Risk
Third-party servers can be hacked, leaked, or compromised
