Classification errors lead to penalties. When in doubt, get advice.

Common Legal Mistakes for Founders

Mistake #1: Using No Terms

Operating without terms leaves you unprotected. At minimum, have basic terms and privacy policy.

Mistake #2: Copying Competitors’ Terms

Don’t just copy-paste. Terms should reflect your actual practices.

Mistake #3: Ignoring International Users

If you have users worldwide, you need global compliance (or geo-blocking).

Mistake #4: Not Updating Policies

Outdated policies don’t protect you. Review annually or when practices change.

Mistake #5: Making Promises You Can’t Keep

Don’t guarantee specific results or uptime you can’t deliver.
