Why We Built an AI App That Doesn't Want Your Data

Every AI app you use wants something from you. An account. Your email. Permission to track. Access to your contacts. Agreement to share data with "partners."

We decided Sygil would be different.

What Sygil Doesn't Do

• No account required — just open and start asking
• No tracking or analytics — we don't watch what you do
• No ads — ever
• No data stored on our servers — questions are processed and forgotten
• No third-party SDKs — no hidden data sharing
• Everything stays on your device — delete it anytime from Settings

Why Privacy Matters for a Thinking Tool

The questions people ask when they're genuinely curious are often deeply personal. "Why am I anxious?" "Does life have meaning?" "Am I a good parent?"

People should be able to explore these questions without worrying about who's watching, who's profiling, or who's selling that data to advertisers.

A thinking tool only works if you feel safe thinking freely.

How We Make Money Instead

Simple: an optional subscription. Sygil is free with 5 questions per day. If you want unlimited access, it's $5.99/month. That's it. No tricks, no upsells, no "premium data packages."

Our incentive is to make the app good enough that you want to pay for it. Not to harvest your data and sell it to the highest bidder.

If you're not paying for the product, you are the product. With Sygil, you're always the user — never the product.
