SaaS Terms and "Standard Contracts" under the Civil Code
SaaS terms of service qualify as standard contracts (定型約款) under Civil Code Articles 548-2 to 548-4 — predefined terms used in transactions with an unspecified number of parties where standardization is rational for both sides.
Incorporation Requirements (Article 548-2)
Standard contract terms are incorporated into the contract if: 1. The parties agree that the standard contract governs, or 2. The provider has displayed in advance that the standard contract governs.
A checkbox "I agree to the Terms of Service" satisfies condition 1.
Unfair Clause Regulations
Civil Code Article 548-2(2)
Terms that restrict the counterparty's rights or increase their obligations and are unconscionable under the principle of good faith are void.
Consumer Contract Act (B2C Services)
For individual (consumer) users, the Consumer Contract Act invalidates:
| Article | Example of Void Clauses |
|---|---|
| Art. 8(1)(i) | Full exemption from liability for operator's intentional/gross negligent conduct |
| Art. 8(1)(iii) | Clauses stripping consumers of cancellation rights |
| Art. 9 | Penalty clauses exceeding average damages |
| Art. 10 | Generally unfair clauses restricting consumer rights |
Key point: "We are not liable for any damages" clauses are void as applied to intentional or grossly negligent conduct in consumer contracts.

Terms may be changed without individual consent if: 1. The change is in the general interest of users, or 2. The change is not contrary to the contract's purpose and is reasonable given the necessity, content, and other circumstances.
Changes must be published online with the effective date before taking effect (Article 548-4(3)).
Best practice: Email notification 30 days before + website posting, with records retained.
Summary
SaaS terms face dual regulation — Civil Code standard contract rules and (for consumers) the Consumer Contract Act. Full liability disclaimers are risky; use a reasonable cap clause instead. Amendment procedures must follow Article 548-4 to be enforceable.
