Terms of use

The plain-English rules for using Thesys. Short, because nobody reads long ones.

01

What Thesys is

Thesys is a decision-support tool. A team of AI helpers reads startup files, checks public information and suggests a decision. It is not financial, legal or investment advice.

AI can be wrong. Every fact links to its source so you can check it. The final decision, and its result, is always yours.

02

Your account

  • Keep your password safe. You're responsible for what happens in your account.
  • One person per account.
  • You must be 18 or over.
03

Your files and results

You own the files you upload and the results Thesys creates for you. You let us store and process them only to run the service for you, as described in our Privacy page.

Only upload files you're allowed to share, for example if they're covered by an NDA with the founder.

04

Fair use

  • Don't use founder emails for spam. Each user can send up to 20 emails a day from Thesys.
  • Don't upload malware or illegal content.
  • Don't try to access other people's data, attack the service or scrape it.
  • We may pause or remove accounts that break these rules.
05

Emails in your name

Founder emails show your name and set your email as the reply address. You're responsible for what you send. Founders reply to you directly.

06

Free use and paid plans

Thesys may offer paid plans. If it does, prices are shown before you pay and you can cancel at any time. Features may change as the product grows.

07

Availability

We work hard to keep Thesys running, but it's provided "as is" and may sometimes be unavailable or change. To the extent the law allows, we're not responsible for investment losses or decisions made using Thesys.

08

Ending

You can delete your account and all your data at any time in Settings → Privacy & data.

09

Changes and contact

If these terms change, we'll update this page and the date at the top. Questions: admin@thesys.app.
