Terms and Conditions for a Mobile App

Most app builders think about terms and conditions late — if at all. It feels like something for big companies with legal teams. But if you're launching a mobile app, terms and conditions are one of the most important documents you'll publish. They're what stand between you and a user who claims your app damaged their device, deleted their data, or caused them financial harm.

Here's what you need to know before you launch.

What Are Terms and Conditions?

Terms and conditions (also called terms of service or terms of use) are a legal agreement between you and your users. By downloading or using your app, users agree to your terms.

They define:

• What your app does and doesn't do
• What users are and aren't allowed to do with it
• What happens when things go wrong
• Who owns what
• How disputes get resolved

Without them, any of these questions are answered by default law — which may not favour you.

Why Mobile Apps Specifically Need Them

Both Apple and Google require apps in their stores to have terms and conditions if the app:

• Requires user accounts or sign-up
• Processes payments or subscriptions
• Collects personal data
• Offers in-app purchases
• Provides any kind of service or content

Apple's App Store Review Guidelines explicitly state that apps collecting user data must have a privacy policy. Google Play has the same requirement. Both platforms can reject or remove apps that don't comply.

Beyond the stores — users expect them. An app without terms and conditions looks unfinished. Enterprise users and business customers will specifically look for them before allowing your app into their organisation.

What Your Mobile App Terms and Conditions Must Cover

1. What the app does A clear description of your service. What does the app do? What are users getting?

2. User eligibility Who can use the app. Age restrictions (especially important if your app could be used by minors). Geographic restrictions if applicable.

3. Account rules If users create accounts: password responsibilities, prohibited activities, what happens if an account is terminated.

4. What users can and cannot do Acceptable use policy. This protects you if a user does something harmful with your app. Common prohibitions: reverse engineering, scraping, reselling, using the app for illegal purposes.

5. Intellectual property Who owns the app, the content, and any content users create within it. If your app lets users upload content, you need to clarify what licence you have to display or process it.

6. Payment terms If your app has paid features, subscriptions, or in-app purchases: pricing, billing cycles, refund policy, what happens on cancellation.

7. Disclaimer and limitation of liability This is the most protective clause in your terms. It limits your liability if the app goes down, loses data, or causes indirect harm. Without this, a user could theoretically claim unlimited damages.

8. Changes to the app and terms Your right to update the app and the terms without prior notice (within reason).

9. Governing law Which country's laws apply to disputes. For UK-based apps: England and Wales.

10. Contact details How users can reach you with questions, complaints, or legal notices.

The One Clause Every App Builder Gets Wrong

The limitation of liability clause. Most founders either skip it or copy something vague from another app.

A proper limitation of liability clause should:

• Cap your total liability to the amount the user paid (or a fixed small sum if the app is free)
• Exclude liability for indirect, consequential, or incidental damages
• State clearly that the app is provided "as is" without warranties

This clause is what protects you if a user claims your app caused them to lose business, data, or money. Without it, your exposure is theoretically unlimited.

Subscription Apps: Additional Clauses You Need

If your app charges a recurring subscription, you also need to cover:

• Free trial terms (if applicable) and when billing starts
• How and when prices can change
• Cancellation process — how users cancel and what happens to their data
• Refund policy — whether you offer pro-rata refunds, no refunds, or something in between
• What happens at the end of a subscription — does access end immediately or at the period end?

App Store subscriptions have their own rules (Apple and Google handle billing) but your terms still need to cover the basics.

Getting It Done Without a Legal Bill

A solicitor will charge £300–£800 to draft app terms and conditions from scratch. For a bootstrapped solo founder, that's a significant cost before you've made a single sale.
