You know that moment when you’re working on your solo project, you’re 17 tabs deep in documentation, and you finally cave: “Screw it, I’ll just ask ChatGPT.”
Yeah. Me too.
And every time, there’s that little voice that whispers: “Should I really be sharing this?”
This is the privacy boundary I’ve developed for myself as a solo builder using AI tools like ChatGPT, Claude, Cursor, and others. It’s simple, actionable, and will keep you out of trouble.
TLDR: The Fast Privacy Filter for Solo Builders
What You’ll Gain:
- Clear rules for what you can safely share with AI tools
- Concrete examples (not vague “be careful” advice)
- Confidence you’re protecting your business while still moving fast
Bottom Line Value: You stay safe while still leveraging AI aggressively in your solo build.
The Problem: Paralysis by Privacy
AI tools are insanely useful. They can debug your code, write your DNS configs, refactor your scripts, design your data models.
But because they’re powerful, you hesitate:
- “Is this safe to share?”
- “Am I leaking business secrets?”
- “Will this data train the model and show up in someone else’s answers?”
And when you’re solo building, you’re both the engineer and the security department. The result? You second-guess yourself into inaction.
The Approach: My Simple Privacy Rule
I use what I call the “Trusted Assistant Rule”:
“Would I feel comfortable sending this exact data to a trusted contractor who’s helping me on my project?”
- ✅ If yes: Safe to share with AI.
- 🚫 If no: Don’t put it in the prompt.
It removes all the ambiguity. And most importantly, it works in context of real solo building work.
The Actual Privacy Cheat Sheet
| Data Type | Can I Share? | Notes |
|---|---|---|
| Public DNS Records (MX, SPF, DKIM) | ✅ Safe | These are public anyway; anyone can query them. |
| Web hosting configurations | ✅ Safe | As long as no passwords or keys are included. |
| Code snippets (non-proprietary) | ✅ Safe | Normal AI usage. |
| Open-source codebases | ✅ Safe | Treat like public code reviews. |
| Architecture diagrams (without sensitive credentials) | ✅ Safe | High-level designs are fine. |
| Proprietary product roadmaps | 🚫 Avoid | Strategic business plans should stay private. |
| User PII (names, emails, phone numbers, etc.) | 🚫 Avoid | Always protect your users’ data. |
| Internal API keys / secrets / tokens | 🚫 Never | High security risk. |
| Full customer datasets | 🚫 Never | Massive privacy liability. |
| Private financial or legal documents | 🚫 Avoid | Handle outside AI tools unless fully anonymized. |
The Human Reality: Why This Feels Tricky
AI tools feel like you’re talking to a human. But you’re not. You’re talking to a system that stores some session history, may persist logs for a time, and (depending on your vendor and plan) may or may not use your data for future model training.
In the case of tools like ChatGPT (at the time of writing, GPT-4o, non-enterprise):
- Your chats are not used for model training unless you opt in.
- Your chats may be stored temporarily for quality and safety purposes.
- The safest assumption is to treat any input as something you’re OK with being seen by trusted support staff, but not the entire world.
The Business Impact
- ✅ I move faster because I don’t get paralyzed by vague fear.
- ✅ I keep sensitive data out of my AI interactions.
- ✅ I leverage AI tools for config generation, code help, debugging, and architecture work confidently.
- ✅ I protect my intellectual property and customer data.
What This Means for Solo Builders
You’re solo. You need leverage. AI tools are a ridiculous force multiplier. But you’re also your own security department.
This cheat sheet gives you a default operating mode that’s fast and safe.
- You don’t need to spend hours reading vendor policies.
- You don’t need to avoid AI entirely.
- You don’t need to expose yourself to unnecessary risk.
Next Steps You Can Take Today
- Save this privacy cheat sheet into your solo builder playbook.
- Apply the “Trusted Assistant Rule” before sharing data with AI.
- Review your AI vendor’s data policies periodically.
- Never paste credentials or customer data into any AI prompt.
AI isn’t dangerous. But careless use of AI tools can be.
The good news? With this simple framework, you stay aggressive, efficient, and safe as a solo builder.
