Launching a SaaS Product? Here's Your Complete Legal Checklist
You've spent months building your SaaS product. The code works, the UI is polished, and you're ready to launch. But have you thought about the legal side? Most SaaS founders don't — until they get their first GDPR complaint, chargeback dispute, or data breach scare.
The moment your product accepts its first sign-up, you're processing personal data and entering into a contract with a user — triggering obligations under data-protection law, consumer law, and your own promises. The good news: most of those obligations are met with a handful of standard documents. Here's the checklist every SaaS product should review before its first customer, with the specific laws behind each item.
This article is general information, not legal advice. Laws differ by jurisdiction and change over time, and how they apply depends on your specific facts. For advice on your situation, consult a qualified lawyer in your jurisdiction.
1. Privacy Policy — Required by Law
The problem: You process user data (names, emails, payment info, usage analytics). A Privacy Policy isn't optional decoration — disclosure of what you collect and why is a baseline requirement under the EU's GDPR and California's CCPA, and it's a condition of most app store and ad-network programs.
Who this applies to: The GDPR reaches any business that offers goods or services to people in the EU or monitors their behaviour, regardless of where the business itself is located. The California Consumer Privacy Act (CCPA) applies to for-profit businesses doing business in California that meet a threshold. Per the California Attorney General, the CCPA covers businesses that "Have a gross annual revenue of over $25 million," "Buy, sell, or share the personal information of 100,000 or more California residents or households," or "Derive 50% or more of their annual revenue from selling California residents' personal information." (California OAG, CCPA) Even early-stage startups under those thresholds usually publish a policy because partners and app stores demand it.
What it must cover: The CCPA gives California consumers a set of rights that, following the CPRA amendments in force since 2023, the California Attorney General lists as: "The right to know about the personal information a business collects about them and how it is used and shared," "The right to delete personal information collected from them (with some exceptions)," "The right to opt-out of the sale or sharing of their personal information," "The right to correct inaccurate personal information that a business has about them," "The right to limit the use and disclosure of sensitive personal information collected about them," and "The right to non-discrimination for exercising their CCPA rights." (California OAG, CCPA) A useful policy explains how a user actually exercises each of these, plus your legal bases under GDPR, retention periods, and international transfers.
The solution: Our Privacy Policy Generator creates a comprehensive policy that covers data collection, usage, sharing, security measures, and user rights under GDPR and CCPA.
2. Terms of Service — Protect Your Business
The problem: A customer misuses your platform, then claims you never defined the rules. Without Terms of Service, you have no contractual basis to terminate their account or limit your liability.
Why the wording matters: Your Terms — and your Privacy Policy — are promises, and regulators treat broken promises as enforceable. If you state that you encrypt data or never sell it, you have to mean it. Inflated or unsupported claims about how you handle data are exactly the kind of statement that draws scrutiny, so keep your Terms and Privacy Policy consistent with what your product actually does.
The solution: Our Terms & Conditions Generator covers intellectual property, acceptable use, termination rights, limitation of liability, and dispute resolution.
3. EULA — License, Don't Sell
The problem: Users might claim ownership of your software or share their credentials with others. A EULA ensures they're receiving a license, not ownership.
When you need one: Pure web SaaS is often governed entirely by Terms of Service. A separate End-User License Agreement becomes important when you ship something the user installs or runs locally — a desktop app, a mobile binary, an SDK, or downloadable code — where you need to define exactly what they may and may not do with that copy.
The solution: Our EULA Generator defines license scope, usage restrictions, IP ownership, and termination conditions.
4. Data Processing Agreement (DPA) — GDPR Mandate
The problem: You use a cloud host, a payments provider, and an email service. Under GDPR Article 28, when another company processes personal data on your behalf, that arrangement must be governed by a written contract — a DPA. The regulation is explicit: "Processing by a processor shall be governed by a contract or other legal act under Union or Member State law, that is binding on the processor with regard to the controller and that sets out the subject-matter and duration of the processing, the nature and purpose of the processing, the type of personal data and categories of data subjects and the obligations and rights of the controller." (GDPR Art. 28(3), EUR-Lex)
Why it's on you: Article 28 also requires you to use "only processors providing sufficient guarantees to implement appropriate technical and organisational measures." (GDPR Art. 28(1), EUR-Lex) In practice, reputable vendors publish a standard DPA you accept; you still need one in place with each vendor that touches your users' data, and you remain accountable for choosing them.
The cost of getting it wrong: The most serious GDPR infringements — including breaches of the basic principles for processing and of data-subject rights — carry administrative fines "up to 20 000 000 EUR, or in the case of an undertaking, up to 4 % of the total worldwide annual turnover of the preceding financial year, whichever is higher." (GDPR Art. 83(5)) A second tier, covering failures such as missing processor contracts, reaches "up to 10 000 000 EUR, or ... up to 2 %" of worldwide annual turnover. (GDPR Art. 83(4)) These are ceilings, not typical fines for a small startup, but they explain why the paperwork is taken seriously.
The solution: Our DPA Generator creates GDPR-compliant agreements covering data types, processing purposes, security measures, breach notification, and sub-processor requirements.
5. Plan for a Data Breach Before It Happens
The problem: A breach is a question of "when," not "if," and the clock starts the moment you discover one. GDPR gives controllers a hard deadline: notify the relevant supervisory authority "without undue delay and, where feasible, not later than 72 hours after having become aware of it ... unless the personal data breach is unlikely to result in a risk to the rights and freedoms of natural persons." (GDPR Art. 33(1), EUR-Lex)
What to do now: 72 hours is not enough time to invent a process from scratch. Decide in advance who declares an incident, which authority you'd notify, and how you'd document it — and make sure your DPAs require vendors to alert you promptly so you can meet your own deadline. (This is a procedural obligation, not a document our generators produce, but it belongs on every launch checklist.)
6. Acceptable Use Policy — Set the Rules
The problem: A user starts sending spam through your platform, stores illegal content, or runs a crypto miner on your infrastructure. Without an AUP, you can't enforce anything.
The solution: Our AUP Generator covers prohibited activities, resource limits, content guidelines, and enforcement procedures.
7. Cookie Policy + Consent Banner
The problem: You use analytics, session cookies, and marketing pixels. Under EU rules, non-essential cookies generally require the user's prior consent — meaning consent collected before those cookies are set, not after the page loads. Strictly necessary cookies (for example, those needed to keep a user logged in) are treated differently from analytics and advertising cookies.
Design it fairly: Consent under GDPR must be freely given, specific, informed and unambiguous, given by a clear affirmative action — which is why pre-ticked boxes don't count and why a genuine way to refuse should be offered, not buried. Build a banner that lets users decline as readily as they accept.
The solution: Use our Cookie Policy Generator + Cookie Banner Generator for a complete, customizable solution.
8. Refund Policy
The problem: A customer demands a refund after 90 days. Without a clear, published policy you're left negotiating case by case — and disputed charges and chargebacks add processor fees on top of the refunded amount. A transparent Refund Policy reduces disputes and gives your support team a consistent rule to point to.
A note on consumer law: In some markets, including the EU and UK, consumers have statutory cancellation or "cooling-off" rights for certain online purchases that a refund policy cannot simply waive. Treat your policy as the floor for what you offer, not a way to remove rights the law grants buyers.
The solution: Our Refund Policy Generator lets you define clear terms for refund windows, conditions, and methods.

Founders often delay this work assuming it means an expensive lawyer engagement before launch. Standard, well-drafted templates cover most of the items above and let you go live quickly; bring in a lawyer to review the high-stakes pieces — your Terms, liability limits, and DPAs — as you grow and your data footprint expands.
Start with the Privacy Policy Generator and work through the list. Then revisit it whenever you add a new data-collecting feature, enter a new market, or sign up a new sub-processor — compliance is a habit, not a one-time launch task.
Reminder: the above is general information and not legal advice, and using these generators does not create a lawyer–client relationship. Data-protection and consumer laws vary by country and state and are updated frequently. Verify current requirements for the markets you operate in, and consult a qualified attorney for advice specific to your business.
